BXX Posted April 20, 2008 Report Share Posted April 20, 2008 Well, my buddy and I decided to go half and half on a HP Tuners setup.. Should arrive in about 10 days I have my 96 CS where I will be swapping to a 97 or 98 PCM.. He has a 07 Impala 3500 and his GF has a 04 GP GT.. I cant wait for it to get in so where can start changing the crappy stock shift points and I really wanna have my cooling fans kick on a bit quicker... Of course once we get the hang of things, we will start dyno tuning out cars, especially since I am gonna be looking into a 3400 top end swap and prolly a nice cam.

BXX Posted April 21, 2008 Author Report Share Posted April 21, 2008 ya know, you guys could make some money back by 'renting' it out. hint hint hint! We intend on in someone wants some tuning done, that we will charge them like $200. $100 of that will be the rough cost of buying credits to register the vehicle to be able to tune it. Depends on what happens, we might buy a tunershop licensing credits, but that would be a large chunk of change. Quote Link to comment Share on other sites More sharing options...
Brian P Posted April 21, 2008 Report Share Posted April 21, 2008 I love my HP Tuner! I have been able to do priceless adjustments to my cars. You should be careful though. I don't like messing with cars that aren't mine due to the liability risk. If you charge for the service, and something should go wrong that they can blame on you (Bricking the PCM, MIL light, driveability problem) it's all on your shoulders. So please be careful.

Anything I might end up doing in the future will be for friends really, but yeah, I know about the liability and that is why my car can be a guinea pig while I learn the ropes. PCM tuning is something I always wanted to do. The best thing about it is I can diag just about any OBD2 vehicle, which that is what can make me some money. Hey Rob, your OBD2, right??

pwmin Posted April 21, 2008 Report Share Posted April 21, 2008 I've been trying and trying forever to figure out how to get HPT to work on a 96 car (w/o actually buying a unit). Nobody could give me a definiite answer on how, so maybe you could tell me. I want it so I can still tune my friend's "96" and tune my Cobalt since DHP won't be supporting it.

BXX Posted April 22, 2008 Author Report Share Posted April 22, 2008 Thats what Brian here told me... I'll prolly snag a used PCM from a 97 CS at a junkyard that I have been pulling parts from lately.

Hopefully Brian can chime in, I think he's running a 98 Venture PCM Quote Link to comment Share on other sites More sharing options...
Brian P Posted April 22, 2008 Report Share Posted April 22, 2008 You can't run a '98 computer unless you repin the PCM harness, and there might be more to it also (like a couple more sensors like a fuel tank pressure sensor we don't have that '98+ does) So you're stuck with a '97. With HP Tuners they get tricky with using up your credits. Powrtuners are much more forgiving as far as what file IS in the PCM and what file you WANT to put in there. For example I grabbed a PCM off ebay from a '97 Bonneville 3.8. Same part # PCM but obviously I don't want to use that file. With the PT I requested the correct '97 Venture 3400 file direct from DHP (you're allowed two per license) and after ignoring some warnings about the new file being different, and will lose the original file, I flashed the new file to it, and all is well. With the HP Tuner, don't quote me but I think it will take 2 credits to use one particular PCM and its original file, and another 2 credits to edit and upload the correct file. Now if you have a PCM with the correct file already (for example, you just installed a '97 Cutlass Supreme PCM in your car) you only need 2 credits total to read that PCM and edit that file. It's a little weird, but that's how they stop people from just flashing a "paid-for" file into different PCM's. If you could flash the correct file into the PCM via a tech-II you're in good shape. You have a resource most others WISH they have. I don't know what HPT would do with a Powrtuner edited PCM, I haven't tried (yet). Quote Link to comment Share on other sites More sharing options...
pwmin Posted April 22, 2008 Report Share Posted April 22, 2008 The other concern, and the main one, (just remembered) was about the tranny. If the PCM is from a 97 Monte Z34, then it's going to think it has a 65e trans. What do you do about that? It's a 95 Z wired for OBD-II (PCM is a 96 Z right now).

Brian P Posted April 22, 2008 Report Share Posted April 22, 2008 it depends on what engine you have. You could get a 3100/4T60e combo from later Luminas thru 2001. 3400/4T60e from '96-99 minivans. The 3.4 DOHC you'd be taking a chance if it would work with the trans, HOWEVER note that my '97 3400/4T60e file has provisions for the 4T65e pressure regulation that are just zeroed out. Maybe that's all it takes? I don't know. Quote Link to comment Share on other sites More sharing options...
pwmin Posted April 22, 2008 Report Share Posted April 22, 2008 Hmm, guess it's something we'd just have to try. I can't believe their customer service isn't interested in trying to figure it out. I'm not sure why they just don't support 96's, either. It's a 3.4. Maybe I will check out someone local's HPT and see if it helps. Do you know if I can get an HPT bin file to look at, or whatever they call it? Quote Link to comment Share on other sites More sharing options...
BXX Posted April 22, 2008 Author Report Share Posted April 22, 2008 Oh, ok duh, it's a 97 PCM Im an idiot Thats what I thought as far as the credits go with my situation. I can get a 97 CS PCM, but their support doesnt show the CS.. Prolly didnt list it because of only a 97 could be supported. But yeah, I have quick and free access to a Tech 2. The company I work for has a few that the shops use. But at the same time, i can simply go a buy a 97 Lumina PCM for like $100 that is already flashed. I just need a valid VIN for a 97 3100 4t60e Lumina so when I order the PCM through AutoZone, their reman company knows what file to flash it to. Ill shoot HPT an email for see if the 97 CS is included. Brain also said in a past thread I made that they dont do 96 PCM's since they have half the memory of the 97's Quote Link to comment Share on other sites More sharing options...
pwmin Posted April 22, 2008 Report Share Posted April 22, 2008 they don't have as much memory, but it's still OBD2 and easier to decode because of less tables, but whatever. You would also think they would do it seeing as how DHP is going to be defunct leaving that part of the market wide open. Quote Link to comment Share on other sites More sharing options...
BIGBULS Posted April 22, 2008 Report Share Posted April 22, 2008 BTW............ Where shiftpoints are concerned, don't go too crazy right off the get-go. I worked up ideal shiftpoints for a STOCK 3100 (L82) on an L-Body, and got 5850-5900rpm for the 1-2, 5650-5700rpm for the 2-3 and 5500rpm for 3-4. These DO take into account the slippage that the 60-E gets off the various shifts and was done using a dyno chart as reference. I know W's tend to make a little bit more power on the top end as their intakes and exhausts aren't quite as restrictive, but I really doubt that you'd need more than a 100-200rpm bump over what I listed (even WITH the CAI you showed in that other thread). But, that being said, you CAN get very NICE performance (if not power) gains by upping the upshift and kickdown limits, and that can be worth as much as 2 tenths in the 1/4 all by itself (not to mention making the car a lot more fun to drive). Either way, dyno your car and then PM me.............I can shoot a few questions back your way, and I can get you some shift tables that you WILL like (my old neighbor LOVED the shift tables I did for his GTP, and I have some experience with L-Cars too).

BXX Posted April 22, 2008 Author Report Share Posted April 22, 2008 I just really intend to start with a slight changes to the gear to gear change based on rpm and tps... I will actually up the WOT shift points once I get some dyno time. Quote Link to comment Share on other sites More sharing options...
timg Posted April 25, 2008 Report Share Posted April 25, 2008 Currently, DHP is the only tuner that supports the 96 3.1 and 3.4. HPTuners will only support 97+. In other words, if you have a 96, you have to swap to a 97 setup even if that includes swapping out the wiring harness, sensors, transmission, etc... (as is the case for the Z34) If there's enough interest, EFILive may get in the game. Tim Quote Link to comment Share on other sites More sharing options...
