tuned my pcm

some guys from the 3800 community got togethor last night, the persons house we were meeting at has a tuner program with his buddy and they happily wanted to scan my car

after 20 minutes we found the obdII port because it was stuffed up by the column, the guy has tuned 5 cars and messed with tune alot so i trusted him.

he gave me the skip shifts, trans pressure increase, set the tranny to shift asap, took ther rev limiter off, and i cant remember anything else

we started messing with some timing and i just got knock so i had him go back to stock values, he saved my orignal file so if i want to go back to stock setting i can

thought id share my little tuning lesson for the week, those downshifts into 1st at 35 are wicked

TO bad You aint in Chicago Cause I need It

tell me about it, the other guy i rode with had an intense pcm that sucked, it didnt have anything changed.

still the 3 injector turn off, no trans pressure increase, and i know for a fact it turned to cooling fans on at 180

I got to find Someone I need to tune mine?

What are you talking about?
3 injector turn off ????

actually im not sure and not going to give you wrong facts.....but something along the lines after you go so fast 3 of your injectors turn off?

someone might fill the rest in

now you know the power of a tuned PCM

damn straight, ive been told a good tune with no knock on a stock pulley will have more power than shit tune, and a smaller pulley

That's not such a bad thing.

Glad you are enjoying the new tune. Perfshift is one of my favorite PCM upgrades as well.

How do you do the skip shifts?

To my knowledge, you must actually activate "perf shift" mode in the PCM, then use a switch to turn it on. I don't do it. Instead, I've programed trans pressures to shift harder.

My Riv's shift from 3-1 is pretty nasty hard and abrupt, even though some say it's not really a "skip shift". I just don't believe it needs to be any harder. It goes from 3 to 1, there's no 2nd gear in there. Same with 4-2 shifts. Throws you back pretty hard.

when you put my car in 3rd that's it's perf. shift!

My PerfShift is on in any gear when I press the gas hard enough.

I LOVE the trans shift changes, compliments of AA.

Dave, if you want my upgraded shift program, it has improved since last year. Lots more high revving during normal driving, but not as jerky when you take it easy. Nasty hard shifts when you get on it. Let me know.

Can I take a look at what you've done AA? I can't seem to get mine right. TIA

actually if im not mistaken he set it to 30% throttle when i have peftshift

the person who tuned me only tuned other 3800 cars and he said the factory settings were very rich thats why i had no knock

he told me our stock values are basically a shit tune, is this generally true for most?

i dont know

Blake.. you need to actually spend a day or two there and get some real tuning. From the sound of it you got the standard things typically done and when he tried some timing your current tune rejected it.

One thing to keep in mind with the trans changes he made is that yoru trans is probably taking a much harder hit as he most likely pulled almost oall of torque management out.

It's a great feeling though, enjoy it while it lasts.

so, is it because the delay was set to the minimum?

TM is there to help soften the shifts between gears. I've lowered mine somewhat, but lots of guys remove it completely. There was someone at the Regal board who said his car would chirp tires on the upshifts. Not long after he claimed GM transmissions were made of wood.

Man U really Need To Get A Tuner, Is Swapping from A 96 pcm to a 07 hard or easy?

i dont nessessarilly neeed one, good local guys are really happy to help me out, im fortunate to have down to earth people here in ohio

Our stock tune is a "Safe" tune, designed to combat many external variables. The stock tune has to work mediocre from northern canadian winters to arizonian summers, and account for drivers who don't run on premium like it says they should. If you tune for your climate and driving style, you can do a lot more with the performance.
