THE owners manual says that any time the battery is disconnected or replaced that the MDS has to be reset by the dealer!
MINES been acting funny since a battery upgrade and was wondering if it can be done myself some how so i dont need a trip to the house of con artist's and since i have my battery disconnected all the time for audio upgardes non stop.
MAYBE FUNKY CHICKEN WILL KNOW AND CHIME IN.
I'd be unstoppable if it wasnt for Physics & Law enforcement
Acting weird as in? By chance does it seem to kick in with more of "feel" now? ANy engine work done?
Stock catback, and stock drivetrain
Typing from a tablet, excuse typos.
its kicking in at lite pedal and at 25 mph in 2nd gear or some times is 3rd gear around 35-40.
yes headers/cats/cat back/fan mod/cai [the basics]-does it with diablo and with it returned to stock also. motors is fine and in prefect tune/trans is fine and been serviced and was very clean. car has 24.000 on it.
IF i'm on the throttle its fine any thing over a 1/3 of the pedal its all good.
driving down my street to day in 2nd and just as it was going to shift to 3rd the mds kicked in and it seems to bog the motor down.
THERES no codes or cel
there has to be a way to teach it!?????

mine has been doing the same thing since i bought it. i thought it was normal. it goes into 4 cyl mode anytime the motor has little to no load on it is how i understood it regardless of what gear it was in. correct me if i am wrong please.
it is kinda annoying.
At one time, long, long time ago.......There was a way to reset MDS. I have used this method a few times to get MDS to work better. Seemed to work, but haven't used it in quite a while. You would start the car, put it in 1st gear, nail it up to about 40mph or so, let it back down all the way to barely moving, (keeping it in 1st gear)after stopping, put it park, shut the engine off, then start again and this was supposed to reset MDS. I'm not saying it will work, but it seemed to work the last time I used it.

WELL-I FIXED IT!!!!!!
RETURNED my tune back to stock-reset the throttle-did the 1st gear run to 4500 rpm-cycled the key-and cleared the havc code AND IT FREAKING WORKED LIKE A CHARM.
CAR drives much better and the MDS doesnt kick in till after 40 mph on lite pedal and 4th gear or above.
drove it for today and rechecked for codes [nothing] reloaded the 93 tune and drove for 30 miles and no codes after 5 key cycle's SO ALL IS GOOD.

Nice. Some say the MDS reset does not work, but it gets it to start working sooner after the battery is disconnected. Confirmed by my MDS light.
My problem was that it was kicking in at 20 mph in second and making a funny noise and boging the motor.
