This thread is for the discussion of the VTCM made by TRS300 (Tim) of LX Custom Solutions.

Beta testers are encouraged to discuss there experiences both good and not so good with the VTCM. We should also share our suggestions for future product development.

This thread would also be a good place to ask questions regarding the installation and operation of the VTCM and it's associated software.

I know Tim has put in a ton of effort to make this product available. I am very thankful to Tim for doing this.

I will make a new post soon to share my experience with the install and driving performance of the VTCM.

"Shift By Code" program... I like this did you tell me about this ? This would reduce one step of the install , right ? plus one less harness and board connection ? This would fit right into my KIS program . Plus one less part to go wrong in the future... Beta is a cool thing ... :thumbs_u:

<< Yes, we could delete the shifter board and no longer need to get under the center console at all. It also opens the door futher that the VTCM controller could be run as a stand alone module that could be run with exising devices like the TranZformer. Meaning, if you had a TZ already, you could use the VTCM controller to handle the shifting strategy, and let the TZ manage the firmness and do the other things it does now...>>

Hello Tim,

I have one more request if you would like to do it. I think I would like to have a up shift rise factor and possibly a down shift fall factor for each gear. Not hard coded.

<< Did you sense the hard coded rise factor in the program I sent? I never heard back... We would need to talk off line about the pro's and cons of exposing this to the user as a variable... I'd also need to better understand what your thoughts are on the Fall factor idea... What your trying to get from it...>>

This would be super awesome!!!!!

I know you are working towards a KIS solution. Ha!!!!

What do you think?

Kirk

PS: The modulation adjustment sounds great. You may be on to something there. Like it.
See notes above...

[QUOTE=cksigmapi;3747864]Not sure if I missed it or not - did anyone check to see if their car had the canbus leads under the steering wheel like mine?[/QUOTE]

I'll check on Friday... Mon-Thur I'm busy making money to try and pay the bills LOL (my real job)...

Hey Chris, Just curious, How would you rate / compare the SFC to the VTCM?... I still think there is a place for an SFC type device in the choices we have today...

Thoughts?

Vtcm

Tim wanted to let you know I am very happy with performance of the VTCM. Now that we found out the problem was a code problem in my car and the unit works just as it should .
I can say it does more than I ever hoped . Hard to be leave all of the adjustments I can make. You talk about tailoring my car to my driving habits now I have mild and wild ...Well Done .

Yeah... Sounds like we tracked down the problem with your car and corrected it... A few more days will tell us for sure... I'm really happy we got this resolved... The other testers are just driving and happy. Every time I check in they just say they are busy etc..., but that the system is working well and they are loving it... So it seems to be a case of no news is good news...

Chris is unique in that he is the only tester with a V-6, and that he also ran another device I created called the SFC in his car. The SFC is dynamic firmness controller that is simple and effective. It senses you gas pedal position and applies increasing firmness to the shifts in proportion to your gas pedal position. It requires no CAN taps or computers... It's a simple plug and play unit... It does not shift the car like the VTCM does however...

Anyway, We put the SFC in Chris's car to be sure it worked as expected (like it does with the V-8's)... He ran the SFC for almost two months before installing the VTCM. I sent an email asking if he would give me some frank fedback on what he thought of both the SFC & VTCM... Part of me still thinks there is a niche for a product like the SFC... As an inexpensive way to increase firmness without all the overhead of computers etc...

This was his response via email... I don't think he would mind me posting it here...

Well, I would have to say that both devices are worth the money. With the said, I was completely happy with the SFC. I am even happier with the VTCM mostly because I have complete control over it. It actually changed my perspective on auto transmissions as I can now set it up to automatically shift as I would. Obviously, it takes some tweaking for it to behave just as I would, but that's the fun part - right?

All in all I would say both products could be on the same shelf and people would grab the one they feel fits their needs best. For those that want a simply firmer shift - the SFC does all they would need. For those that want full control over every aspect of shifting, obviously the VTCM is for them. I prefer the latter.

I can see it being similar to the predator in that we find "canned tunes" specific to each motor that behave predictably and consistently. Of course, leave the ability to change the details in there.

Tim,

Would a device like this prevent LIMP mode on a Jeep when used with a Mopar TCM? I think it would have to control the torque management in order to solve this problem.... Sorry disregard my question Tim you touched on it in posts 17 and 23....
 
#147 ·
Tim,
You're right about me not minding! In fact I was going to post up my response but you beat me to it :)

To expand a little, if the SFC was the only thing I tried, I would've been completely happy with it. If I weren't so eager to tinker with things, I might have just stuck with it lol. BUT, I am very happy I decided to go with the VTCM. I wish there was more time in the day to play around with it. There are some things I'd like to try that I just haven't yet. And you're right, no news is good news. I've had zero issues with the VTCM so far. Oh wait, as I type this I remembered that the CC control still controls the VTCM when CC is engaged. I only use it once in a blue moon so I almost forgot about it. I know thats just a coding thing so I'm sure it's an easy fix.

Anyway, once I've had time to make some tweaks I'll share my mode settings with the other testers. The only real tweak I've made so far was adjusting te float setting because it had too much lag for my taste in the 2-3 and 3-4 upshifts when I punch it to get on the e-way then settle into a cruising speed. I noticed it hung out in 3rd too long. Easy fix of course, just one of those things I wanted to share.

Oh and I'll be sending out some stuff for you on tuesday probably (SFC and rear seat covers) so keep an eye on your email for a tracking number. Don't hesisate to remind me as I tend to be a tad scatter-brained these days with our son on the way :)
 
#148 ·
I'm keeping up with this and prob. going to be selling my Tranzformer since there is no support for it and it keeps turning off!
 
#149 ·
If your serious PM me... I've been considering a price adjustment down to $250 ($50 less).

Any new sales will provide a rebate for those who already bought in... I'll not make any money but my goal was to break even on the Beta units... I'd like to simply get more folks on board at this point and maybe reward thoes who helped me get this run off the ground...

Also, I'll say this again for those that have not heard it... The VTCM controller could be run in conjunction with other devices like the MTCM or the TranZformer (or both). I see no reason why it would not work. The TranZformer could continue to deliver firmness and the other features it does while the VTCM shifts the car for you based on your custom settings... Hope that makes sense...

Project update.... I would say the Beta test of the VTCM is a success... We had a few bumps but the outcome was exactly as I had hoped, it's a better solution today then when it started... I'm surprised actually by how many changes were implemented. But also pleased that most of the changes were minor. Nothing needed to be changed at the core of the logic... :)

I do have some work to finish... Here's my to-do list... It looks like a lot but actually it's mostly "Nice to have stuff" with the exception of the first two bullets... Even-So... I'd like to try and get most of this done before the next release...
  • Fix the CC wand defect (*VTCM still gets adjusted with CC Engaged)
  • Generate Operating instructions...
  • Make the Kick-Down firmness a % of the US firmness. Alter VTCM Manager for these settings.
  • Suppress up-shifting while brake is on.. (Happens as float is still dropping during a braked deceleration)
  • Default Common settings by car model
  • Default Mode Settings. (Canned settings)
  • Remove any inactive components from the VTCM Manager
  • Custom RGB Color settings...
At this point I would declare the system "Stable"... :beerchug: Not sure of the future of the VTCM however... I Love it... Those that have it seem to really enjoy it... But the lack of interest might end things... :grind: It's surprising actually... For what you get from this it's odd that more folks are not interested... :doh: Oh Well... Maybe it's one of those things you need to experience to appreciate...

Gotta learn how to put together instructional Videos now... More later...

Best Regards...

Tim it's easy to see we are happy it looks like we left you a positive I TRADER feedback.

I hope there is a future for the VTCM . It does fIll the hole the automatic transmission has. By that I mean those times you step on the gas pedal or turn that corner and nothing happens then it kicks in we have all been there. The tranny was not ready for what we had planned . Not the case with the VTCM it's ready. My feeling if this was not needed why is Dodge going to offer the sports shift option starting 2012 which is a simple version of the VTCM without adjustment and different modes to pick from. It's hard to say how the car feels with the VTCM other than to say it feels ready at all times.. I like to feel my car shift both up and down . If needed I like the tires to chirp when going into 2nd gear with 50 to 60 % pedal . I call that mode 3 setting for my car . That still leaves two other modes for different styles of driving . Some of the other guys might not like that setting that's the cool thing about the VTCM don't like it change it . I had another one of the beta testers e-mail me his favorite around town mode . I installed it in mode 1 this by itself is a great feature of the VTCM being able to email modes back and forth between your friends. I wish my D P Turner would do that.
I did not know Tim when I signed up for this . Did not take me long to find out the passion he has for this device . My car had more problems than all of the other put together. Tim was there the entire time working thru those problems that had nothing to do with the VTCM it was my car . Even so he did offer to refund my money more than one time. I did not want a refund I wanted the VTCM to work even with my problems I knew I did not want to drive my car without it.
So if you are on fence about this PM Tim I know he will work with you. Ask all your question ,concerns and whatever else . Keep it in mind he will be there for support, he will return your emails ,return your phone calls and he will want you to enjoy his creation .
Thanks Tim for working with me I am so happy I stayed with the program.....

Tim,

Just wanted to say that I am experiencing no negative issues with the VTCM. I have been super busy til now. I still would like to discuss two ideas regarding upshift factor and a float curve.

My car will be in the body shop in a few days for a few days. Damn stupid drivers.

I'm on an all day ride on the Harley on Saturday Kirk. Can you talk by phone on Sunday sometime? Sounds like you have some Ideas that might be better discussed in person... If you think you can put it into words go ahead and write it o I can think on it before we speak. Otherwise we can just wait till we talk.

Been doing that for 3 weeks now . People keep using the shifter putting the VTCM in pause . I tell them do not move the shifter . :doh:
I am sure in time I can make the point .. Wish Tim would re-post the thread again that made use all want to test the VTCM remember the Forum God pulled it before Tim was a vendor .
 
#159 ·
I love my VTCM. I am amazed at the lack of interest in it. There once was a time when it seemed everyone wanted a partial throttle shift and firmness kit. You can now get the firmness from a few vendors but not the shift strategy part. I would think people would be lining up for the VTCM.

I would also let someone check it out in my car.
 
#160 · (Edited)
Hi Guys, Pleasant surprise to see the thread active again! LOL... As for the lack of interest part... Who knows? I don't get it... I'm loving my ride and doing this project too... Fortunately I have a 33 year career job that pays the bills...

As an update we did get another tester in the group (trsmagnum) and his purchase is what gave you guys the $40 rebate. This brings the system to its new cost of $260 shipped.

As always, I'm working on the program based on your feedback. You have all made it clear you are very happy with what you have but with anything like this, there is always room to improve and polish the design...

So with that said, I'm currently running a Version that is different than yours in the following ways...
  • Repaired Defect: The control of the VTCM using the Cruise Control wand does not work if the A/C is on... This defect is now repaired...
  • Diminishing Rise Factor: If you recall we added new setting called "Rise Factor" about a month ago. We did this to custom tailor the way each gear moves toward max target (specifically, we wanted 1st gear target to rise faster than the rest). Adding this factor worked well and gave us a better feeling 1 > 2 shift target based on pedal position. But it also introduced a kickdown speed to 1st gear that was a bit too aggressive. The rise factor now diminishes (or gets cancelled) as you move toward max throttle... So the target rises more quickly to begin with, but continually slows down and reaches Max upshift target only at max throttle. Just like it used to be. This resolved the agressive kick-down and also got rid of the "Holding Gear" feeling at ~ 75% pedal position. Simply, it orks like it was supposed to now...
  • Normalized Float. As you press the gas it raises the shift targets. When you let off the gas these targets will "Float" back down based on the float rate you have set. Float is necessary to dampen the rapid changes in gas pedal movement by the driver. If we did not dampen this the car would kick-down and up shift much too often... The problem with the original float strategy is it would come down at the same rate no matter how far it got pushed up to... So if we made a hard acceleration (max throttle), and let off immediately, the shift targets would have been pushed to max, and then have a long way to float back down... Holding the targets up for a little time is good, but in some conditions it can seem to hold RPM high for to long. The change that was made is this... No matter where the float gets pushed up to (let's say max), the float now falls rapidly down to 10MPH above the current speed of the car. From there it then floats down at the rate you have it set at. What this does is makes it so that the time that the float is engaged is always the same no matter how far it gets pushed up beyond the current speed of the car...
  • Inhibit Float Induced Up shift: In the past we could have a situation that while slowly braking the speed of the car is dropping slower then the targets are floating down. This condition can produce an up shift while lightly braking. It did not hurt anything but would just seem odd that the car would up shift while braking, only to be followed by a downshift again as car continues to slow down. The change introduced says that if the brake is on, the float rate will be stopped if the target is < 10MPH above the current speed. In other words, it inhibits upshifts while the car is braking... The float/targets will follow the speed of the car as it slows down...
Let me know if you would like to do an update your program files to this new version. I've been running these changes for about 5 days now and like them a lot. It's the version I wil be having TRSMAGNUM (Tom) start off with...

Best Regards...

Tim,

Cool to see you still working this. The new float function sounds interesting. It is pretty much what I had in mind but got super busy again and never made a call to you. If we could set a float down curve I think that would be really cool. I do find that the VTCM programming (user) is very subjective. I think that hard code settings might not work well. I hope you can find a way to make it so we have control over these new things.

I never felt any change with the upshift rise factor coded in the test version I am running. It is hard coded and would probably have been better with a user control instead. I know you are trying to keep it simple but I am concerned with hard code parameters that can't be changed. There is just no way to make everyone happy with the same settings.

I think if you could do a user controlled float I would have no more wishes.

What do ya think?

Thanks again for your efforts.
Kirk

Hey Bryce... Sorry I did not get back to you on this. I remember we spoke on PM and you said you always run in auto-stick at the track and that you did not want any auto-shifting at all.... I would have been interested in what your thoughts were on how the VTCM could help while you are racing however... But I thought you were not interested when we spoke...

My thought was that you would probably always initiate the down shift yourself when going into a corner... And doing so would cause the VTCM to go into pause... But then as you accelerate out of the corner you could re-engage the VTCM with a flip of the CC wand and it would shift for you until you take control again... And as I said, taking control is as simple as initiating a shift yourself causing the VTCM to pause... Since the VTCM shifts while in A/S it's not the same as going in and out of "D"... It's much more seamless...

Fun thinking anyway... :)

How does this work with the Jeeps since we don't have the same tranny settings in the Pred/Trinitys that the LX's do. IIRC, didn't you say that the Auto Up Shift needed to be disabled? Jeeps can't do that unless we have a MTCM.
 
#175 ·
Theoretically since the Jeep mirrors a lot of LX stuff, and spending some Off Board time in emails schooling and chatting with trs300 ...

This product should work in the Jeep.
 
#178 · (Edited)
Tim any new updates or news you would like to share about the VTCM . I know the last one for my car using both B and C bus made all the difference....
Hi John, Yes... The unit was always reading from both busses but changing the source of a data point from one to the other did help out.

Recent news is the VTCM was deployed on a 2008 Charger and for the most part went pretty well... had to do some minor adjustments on the CAN messages for the Key position and the Cruise Control wand movements. We also deployed a new shifting board that worked perfectly first time thanks to help from PLCMAN.

All in all I'm very happy with the system but I'll continue to make it better (and simpler) as time goes on...

It's been so long since I've driven my car in "D" that I decided to give it go tonight on the way home from work... I almost puked... I immediately got those bogging soggy shifts that ALWAYS happen WAY to early. And the high flaring kick downs that send the RPMs almost to max way beyond any good pulling range... Needless to say I re-engaged the VTCM after only a few minutes of driving in "D". I'd almost forgotten how much I hate the stock TCM shifting plans... Boy was that a rude reminder... LOL..

I couldn't agree more love my VTCM would not want to be without it . Hope the other beta testers feel the same way ? This might not be a beta program any longer in my opinion it is a working sell able product now . See if Tim feels the same way about his baby being non beta now ....I know it's only been 2 months in the beta program but Tim has 6 plus months on this version before he offered it up for testing . The problems I had were car and or install problems not VTCM problems . Most if not all of my problems could be traced back to installing the controller under my seat which I do not recommend. I needed to extend my harness in order to do that ,plus tap into bus locations not used before .
................................. Install the controller in the glove box and you won't have these problems ...........................
 
#180 ·
Tim and I recently installed the VTCM on an 08 charger. Like he said above everthing went well and we got it working, there was just a few minor differences. I love the VTCM so far and I have not even had anytime to touch any settings yet. Whenever I have the time I will post a writeup on the vtcm. Can anyone save me a little time and tell me what settings you changed if any for an SRT8?
 
#181 ·
Tim, I will try the new updated file when I get home and see if the wand works. Sorry I havnt got back with you. Ive been pretty busy and really havnt even had a chance to truly drive my car yet.
 
#184 · (Edited)
Btw Tim I sent you some stuff!
LOL... That almost sound Illegal... I did get the SFC in the mail. Thank you... Hope all is well Chris...

BTW Folks... I have three of these systems left for a cost of $260 Shipped in the USA. It truely is a unique system. I'd love to have one go into a Jeep... And as I've said before, the VTCM shifting controller could easly deliver it's strategy in conjunction with existing devices like the TranZformer, Silver Box, etc...

Cheers!

Finally had time to play with this today. Its awesome...I love the reaction and gear shifts when you get on it, and the float when you let off. I still didnt have a chance to load the new file you sent me Tim. I will do it tomarrow. I notice my shifts are moderately hard at mid throttle but at full throttle they feel the same as stock. I need to fix this. I want neck snapping shifts all the time. I think I may have tweaked the config file the wrong way. I just simply replaced 5900 with 6200 not remembering to factor in your equation.

Thanks for the write-up Kelly... See comments below...

Finally had time to play with this today. Its awesome...I love the reaction and gear shifts when you get on it, and the float when you let off. <<This is REALLY what makes the VTCM unique. The VTCMs shifting strategy (logic) is much different then stock (much better IMO)>> I still didnt have a chance to load the new file you sent me Tim. I will do it tomarrow.<< I'm actually going to send you a new file... Check your email... Keeps getting better... :mrgreen:>> I notice my shifts are moderately hard at mid throttle but at full throttle they feel the same as stock. I need to fix this. << Be aware that as you approach full throttle the firmness effect deminishes... This is true with ANY of the devices being sold that increase shift firmness using the "Electrical Bypass" method... The stock NAG1 can only produce so much firmness... Period. The stock TCM will move the firmness toward maximum under full throttle conditions... Because of this the firmness effect deliverd by the VTCM (and all devices like it) get cancelled out... Think of it this way... These types of firmness devices bring the firmness on sooner then the stock TCM would... But they cannot produce more firmness then is available...>> I want neck snapping shifts all the time. << Oddly enough the most "Neck Snapping" effect is when the RPMs are spinning high with the gas pedal in the 50-70% range... This is why it's so cool to have control over the actual shift points... TRUTH IS IF YOU WANT TO HAVE MORE FIRMNESS AT WOT CONDITIONS YOU NEED BLUE TOPS OR AN UPGRADED (PERFORMANCE BUILT) TRNSMISSION... YOU NEED TO MAKE SOME TYPE OF MECHANICAL UPGRADE.>> I think I may have tweaked the config file the wrong way. I just simply replaced 5900 with 6200 not remembering to factor in your equation. << No Factors involved... Just be sure your rear gear ratio, tire diameter, and Max RPM sttings are adjusted for your car...>>
