PCM Tune

Would anyone like to tune my car? I can really use whatever extra gas mileage I can get, and a higher speed limit on the governor is always fun as well. Frederick MD area. It's a bone stock 96 S/C.

Might check into this. Not sure if deekster is still tuning or not.

IIRC HP Tuners still won't do a '96. I don't have a PowerTuner anymore.

Turtle, did you have any luck tricking HPT into working on a '96? Or converting to run on a '97 PCM?

I haven't tried any '96 with hpt.

If you're willing to give it a shot, and there's no risk of bricking it I would be glad to let you go for it. I'm an IT guy, trial and error is just a regular occurance with me.

It's not that simple. HPT doesn't have the OSID for that PCM in their software, so it won't work period. It won't even try. If you can find someone with a DHP PowerTunr I'd be happy to look over the file and make some changes for you, and explain what I did and why so you can take it from there on your own. I still have my old PowerTuner software.

I'll do what I can. Will post back here if I find anything. Sorry if I sound a little dumb :p

The only stupid questions are the ones you don't ask. Never apologize for that. There are a few threads about tuning here, but it's hard to sift through, so no worries. Do search, but it isn't the end of the world if you ask a repeat question.

I would like to respectfully disagree on that one. Every question ever asked will sound stupid to someone because that someone will know everything about the mentioned topic, and it will be common knowledge to them.

Well you go ahead never asking questions and I will happily not answer them!

Alright
On a related note, what if I got a PCM out of a 97-99? Would it work? I don't see any immediate issues.

What a stupid question!










Ok, the transmissions are very different, so no. Unless you take the transmission too, but that's a bigger project!

Well, my tranny has been giving me a few issues lately, to that's not entirely out of the question.

Gotcha but that's a whole different kind of project. Keep your eyes on ebay for an old DHP PowerTunr (they aren't produced anymore) as that's pretty much your only option for tuning a '96 PCM, and your easiest way out.

Thanks all for the help.

I can't figure out how to post a new topic so I'm just going to ask for help here. I loaded a bin file from scott on to my car that has a different osid and now it down shifts funny. like if you are cruising around 40ish then give it about half throttle it will feel like its takes a second then it slams. I have both hpt and dhp. so after loading the new bin with dhp I read the file with hpt. basically all the shift tables are the same as my original tune that shifted fine, so I don't see any problems. what could be happening? I assume it has something to do with it being a different osid. I could just upload my original file with hpt, but i wanted to edit with tiny tuners which i have to use dhp. and if i use dhp i have to use an different osid since mine is not supported. is it just not going to work? am I missing something here? Thanks in advance

Not sure what's going on. I never had that problem.....I'm at work now. I can't look at the file until I get home tonight.

If all the shift tables are the same, it shouldn't be a problem. That doesn't make any sense.
Which file did you load? The '98 file I sent? I have a N* TB and a ported SC on my Riv, so my MAF table would be wayyyyyy different than yours. The TP sensor range is different also. Maybe that has something to do with it?

Thanks for the quick reply Scott. So I guess I was wrong about the tables being different. I went back and compared the files again and there are some differences, so I changed all of them back to what I had originally and everything is fine now. Thanks again Scott for the file and the reassurance that it should work. I got a little freaked out for a bit just thinking of the worst.

All it takes is 1 wrong number to mess sh*t up! Glad you found it!

Anytime
