BXX Posted March 17, 2008 Report Share Posted March 17, 2008 I did quite a bit of searching... Found tons of cables to connect aldl to laptop for diag and code reading, but nothing really for reflashing/tuning I know about DHP, but they seem, uh, outta business maybe?? Hell, couldnt find anywhere to buy from them in regards to my vehicle.. Anyone have some info to help me out here.. BTW, my car is a 96 CS 3100...

Brian P Posted March 17, 2008 Report Share Posted March 17, 2008 Yeah the DHP Powertuner is discontinued. For your situation, your option is to go with a '97 PCM (specifically) and run a '97 Buick Century program. You can tune that with HP Tuners programmer.

What is so different about the 96 and 97 PCM's??? Quote Link to comment Share on other sites More sharing options...
Brian P Posted March 18, 2008 Report Share Posted March 18, 2008 '97 PCM is 512k, '96 is 256k memory size, so the program is not interchangeable. It wouldn't matter except that I don't recall HP Tuners being able to read '96 PCM's. Quote Link to comment Share on other sites More sharing options...
BXX Posted March 18, 2008 Author Report Share Posted March 18, 2008 Oh, ok... So just as simple as swapping a 97 Cutlass PCM and flashing it with a 97 Century's programming. Seems simple, do you know off hand if the PCM pinouts are the same?? If not, I can just use the PCM wiring info from Mitchell Quote Link to comment Share on other sites More sharing options...
Brian P Posted March 19, 2008 Report Share Posted March 19, 2008 PCM's interchange no problems. I'm running a '97 Venture PCM with my '96 Lumina harness. Quote Link to comment Share on other sites More sharing options...
BXX Posted March 19, 2008 Author Report Share Posted March 19, 2008 So its plug and play, just it needs the Century programming.... Sweet, I should pick one up soon... Reman PCM's are dirt cheap and come preflashed.. Quote Link to comment Share on other sites More sharing options...
Brian P Posted March 19, 2008 Report Share Posted March 19, 2008 actually (I had a brain fart) you could look for a '97 Cutlass Supreme PCM or file too. Most of the PCM's from '97 are identical, meaning you could get one from an H-body, W-body, U-body (van) but the file will be wrong. If you want to run the PCM as is for a little while, you'll need to stick with the same powertrain and body. Quote Link to comment Share on other sites More sharing options...
BXX Posted March 19, 2008 Author Report Share Posted March 19, 2008 Ok, sorry that I may not be understanding this.. But I just need a 97 CS 3100 PCM, plug it in, and it can be tuned via HP Tuners?? Or will the new PCM still need the Century programming file?? Quote Link to comment Share on other sites More sharing options...
Brian P Posted March 20, 2008 Report Share Posted March 20, 2008 Just tune the '97 Cutlass Supreme file. I just forgot about it because I thought the '97 CS got '96 carry-over parts, but it didn't. I'm not positive but you could try to contact HP Tuners and see if they added in '96 GM PCM support. The Beretta guys were lobbying for this, I don't know what became of it. That would make your life very easy. Quote Link to comment Share on other sites More sharing options...
BXX Posted March 21, 2008 Author Report Share Posted March 21, 2008 I looked at their site... It shows only 98 up 3100 Century's... But that doesnt matter, as long as I use the 97 CS's PCM right??? I just have to make sure it is initially flashed with a 97 3100 file such as the Malibu or Lumina?? Here are the V6 vehicles that they support from what is on their website.. 97-02 Firebird/Camaro 3.8 00-05 Chevrolet Impala 3.4, 3.8 06-08 Chevrolet Impala 3.5, 3.9 97-01 Chevrolet Lumina 3.1, 3.4, 3.8 97-03 Chevrolet Malibu 3.1, 3.4 06-08 Chevrolet Malibu 3.5, 3.6, 3.9 (3.5 in 07 only) 97-05 Chevrolet Monte Carlo 3.1, 3.4, 3.8 06-07 Chevrolet Monte Carlo 3.5, 3.9 97-05 Pontiac Bonneville 3.8 97-05 Pontiac Grand Am 3.1, 3.4 06-08 Pontiac G6 3.5, 3.6, 3.9 (3.5 in 07 only) 97-05 Pontiac Grand Prix 3.1, 3.8 98-05 Buick Century 3.1 97-05 Buick Lesabre 3.8 97-05 Buick Park Avenue 3.8 97-04 Buick Regal 3.8 97-99 Buick Riviera 3.8 99-04 Oldsmobile Alero 3.4 07-08 Saturn Aura 3.5, 3.6 BTW, I crossed PCM's and it appears looking up a 97 CS shows its only interchangable with a 97 CS and a 97 Cutlass... But I look up a 97 Century and it says it is interchangable with several vehicles, including the Malibu and 97 CS and has a different part number... Hmm, if you arent able to help me (which youve been doing great help already) then I will CALL HP Tuners... I was gonna email them, but this is something that seems like it would be easier handled by calling them.. Quote Link to comment Share on other sites More sharing options...

BXX Posted March 21, 2008 Author Report Share Posted March 21, 2008 So those are all the same PCM in 97 model years??? Are they also the same for other model years as well.. BTW, thanks for all your help guys.. Otherwise I would be going with MegaSquirt... But a burned out MS cost about $300... Another used PCM from a JY cost $50 Quote Link to comment Share on other sites More sharing options...
ManicMechanic Posted March 21, 2008 Report Share Posted March 21, 2008 That's what PCM works on a 1997 Cutlass Supreme, what else it can come out of. Quote Link to comment Share on other sites More sharing options...
BXX Posted March 21, 2008 Author Report Share Posted March 21, 2008 Ok... perfect man, really appreciated!!! well since you posted the pn, im gonna put my hook up at the GM dealer and put him on a hunt to see what all years and models it is the same as... Just to have all the info I can have on the PCM.. Quote Link to comment Share on other sites More sharing options...

Brian P Posted March 21, 2008 Report Share Posted March 21, 2008 IIRC the PCM Part # is 16217058 off the top of my head. If you want it to be plug and play with the correct file (like a used one) you're stuck with the '97 Cutlass Supreme file, or possibly '97 Century, '97 Grand Prix SE 3100, and that's really it. If you do call HP Tuners, ask them if they can supply you with the correct file you'll need ('97 CS) and if you can change the VIN #. Unlike the DHP powertuner where you can flash any file you want to a compatible PCM (which makes things so much easier), the HP tuner registers the PCM you connect to and I think you cannot download a different type of file to it. So I'm thinking you're stuck with a '97 CS PCM but double check with them. I'll check the tune repository if there's any '97 V6 files available however most people that post up files have a V8.
