    Custom Computer Tuning

    Hey, I finally got my programmer, and all the adapters, now im trying to program my prom chip in my 93 grand am, with a 3.3L (3300) v6, i put a manual trans in it( getrag 282) and the car is having trouble idling, and also my speedo says im doing 18km/h when im doing 90km/h , now i need a good program to modify the prom chip, but i dont know what to use, and is it really hard, i did some programming back in high school, and am very computer literate, and i have programmed sats for years, but i have never attepmted to do cars, anyways, i need to fix the idle, service engine soon, due to qdm failuer, and no tcc lockup. and the spedo. please help me, i need this fixed asap, the car is stalling at every stop. thanks.

          ECM swap time... I don't think anybody make a definition file for the 3.3........because nobody uses it.
          Okay now, that's enough of that.

            would he need to swap the ecm or just a memcal? if its a 93 it might be running the 7730 or 7727 ecm and since a motor is a motor and doesnt care what runs it, maybe the right chip would work, like one from a berretta or a j-body.

            i think the 3.3 was a 90 degree motor wasnt it?

              Yeah, the 3.3 is a smaller 3.8 V6. Great little engine, but no aftermarket, and only made for a few years.

                I don't think the 3.3 uses any ecm we're familiar with... just like how the 3.8's use a different ecm from us.

                  ok, so what ecm could i swap into it? i programmed my chip last night and the car starts but it is no different than the stock chip, there is no difference. would a computer from a 91 w body fit in? because i have tons of those laying around.

                    You might want to go on thirdgen.org and then go to message boards/ computer tuning and talk to "Grumpy" in the message boards. He has done some work with the 90 degree V6s somewhat unique ECM code. Maybe something from the '8253 ECM would work for you. It is a MAF 90 degree that I think uses the same sensors and such.

                    BTW what flywheel setup did you use?

                      Contact the guys at tunercat. The only thing you need to change is the road speed constant. That should be relatively simple to find with an ALDL definition file. You could probably bribe them by saying you'll pay them the cost of a definition file for their help... Since you're now running a manual, you're probably going to need to change your throttle follower to keep from stalling at stops, but you could probably get by by opening the throttle via the throttle stop, and just accepting a "0" IAC count.
                      Okay now, that's enough of that.

                        Well first off i used a 3.1L flywheel, with all the holes welded in and drilled out to the bolt pattern that i need, then match balanced to the auto flexplate. works great. ok, i started a thread at thirdgen.org, i asked them what they thought, and i was looking at tunercat, and they dont have my application in there list, i should email them anyways though. how do i find out what ecm i have? i ripped the whole thing apart and i cant find any numbers, i also ripped apart a ecm from a 91 gtp and there is no numbers there, but the board look identical, they even have the same chips on it, just different plug ins on them, but how do i find my model number, any help, i feel like i just wasted alot of money, i really need this fixed. thanks for everything,

                          you likely have a 1228706

                          Can you take a picture of it? Supposedly it is in the same family as the '49 and '30... which could mean you just burn a 3.1 V6 prom, move a couple wires, and tune it.... if you wanted to go that way. I think it would be easiest just to change that road speed constant, but you have to know where it is located first...

                              You can use a 3.4 *memcal*, the chip (binary) won't work with your computer or engine. Since you've already got the moates adapter and atmel chip, program a 5 speed V6 binary and see if it does anything wierd.

                              I'd recommend BFUZ for your application. the 3.3 is DIS right? I can't imagine it being a whole lot different internally.... The 3.1 (bfuz) binary won't run your engine well, if at all. It would require retuning the VE tables. But the good news is you *can* tune it.

                              Highly recommend tunerpro.
                              Okay now, that's enough of that.
