Mods Face Off Result: B&G Stage II Flashed PCM

This test consisted of testing the B&G Stage II PCM on an extensively modified 2005 Magnum RT at the Mods Face Off 5 (MFO5).

Mod Tested: B&G Stage II PCM
Date: 10/12/06 - 10/13/06
Dyno Location: SVS R&D, Sacramento CA
Track Location: Sacramento Raceway, Sacramento CA

***Remember to always review and keep in mind the Mods Face Off Testing Methodology Q&A while reviewing these results.***

The Good:

• While the averaged maxes show minimal gain, there seems to be a consistent gain throughout the power curve
• The in neutral 3500 max RPM has been removed (is this truly good?)
• Torque management has been reduced, and as advertised, that has a minimal effect on shifting (not shown here).

The Bad:

• You cannot use this flashed PCM with the Superchips tuner, thus you're giving up the adjustability of wheel size, max speed, minimal shifting dip (not shown here as fuse 17 had to be pulled in order to make this flash work; it otherwise attempted to go into limp mode)
• There is currently (as of 10/18/06) a known issue with limp mode. The B&G Stage II has the rev limiter set to 6800 RPM. The TCM, however, is programmed to go into limp mode when it detects an RPM above 6300. Many reports have been made that, while burning out, the car (as it transitions from hi RPM in 1st to low RPM 3rd limp mode in a split second) feels like it blows apart. Also, reports have been made that upward of 15 minutes is required before limp mode is reset (or you can pull the battery lead).

The Numbers:



The these are the numbers after installation of custom ported and polished heads & HEAT Stage I Non-MDS cam. PLEASE NOTE that there is only a single run for the B&G after the installation. The other two runs data is only half complete and therefore could not be used. I caution you from drawing conclusions about the power effects from this dataset. Its just not complete enough to fairly compare. However, it is interesting to note the AF ratios graph. Clearly the B&G is fattening things up; not a bad thing at all, considering more than a couple eyebrows were raised at the 13.7 AF with the stock PCM (concerns were that is on the lean side of safe for a naturally aspirated engine).



The Graphs:

These two pulls closely follow the averages for the entire set. This is average vs average, not worst vs best.



And the AF ratio comparison for the same run pictured above:



The these are the graphs after installation of custom ported and polished heads & HEAT Stage I Non-MDS cam. PLEASE NOTE that there was only a single run for the B&G after the installation; that run is graphed here compared to the average run of the stock set. The other two runs data is only half complete and therefore could not be used. I caution you from drawing conclusions about the power effects of the B&G from this dataset. Its just not complete enough to fairly compare. However, it is interesting to note the AF ratios graph. Clearly the B&G is fattening things up; not a bad thing at all, considering more than a couple eyebrows were raised at the 13.7 AF with the stock PCM (concerns were that is on the lean side of safe for a naturally aspirated engine).

Also note that, toward the end of the run for the B&G things get screwy. Not sure what was going on, but clearly something wasn't happy. This deserves more testing next time around.

Why no info? Good? Bad?

[lafrad]

it probably gets filled in as we go...

[MattRobertson]

I'm guessing he goofed and accidentally posted a work-in-progress

[Redfox0099]

Regardless of what this says

My car wouldn't run without it

Yep . Should be all set now.

[Husker]

Did you guys test the SRT B&G flash?? I have read that it really makes a difference..

[CoolVanilla]

No. The only PCM flash we had access to was the 5.7. MFO6?

[lafrad]

man that goes pig rich after the shift... B&G Goes RICHER and it has more power?


Odd-ish....

Do you have results (either for this thread or another one) for the B&G operation AFTER the heads&Cam?

[MattRobertson]

Yes, but I expect its taking some time to chew thru both this info and whatever his day-and-a-half job is throwing at him. Don't worry there's data and plenty of it. Including track results.

[CoolVanilla]

After data is up. But, PLEASE read my notes. Something went wrong during the B&G after testing, and the numbers are just plain weird. Not sure if the B&G was screwing with things, or we lost a signal into the dyno... at the time we knew something was up, but time just didn't allow for redo's.

In all fairness this really deserves more testing, and I strongly suggest no power conclusions should be drawn for the after heads/cam + B&G tests.

Which computer did we start the night at the track with?

The B&G. Care to offer any impressions as the official track driver?

[gotls1]

Well, I'm pretty sure that the second run after switching the computer out was the miraculous 13.5. After that, they were 13.7 as long as there was no significant wheelspin. Just an observation.

[MattRobertson]

"after switching the computer out" means that you went back to stock PCM and times dipped down to 13.5, followed by 13.7's? The runs with this cam and PCM/TCM combo are going to be closely watched I think.

Or are we saving discussion of the times and performance for an overall results thread of some kind?
