    Re: PCM Tuning Progam for NorthStar V8's?

    I have a friend with a 96 that needs it.

    I just stumbled across it when I put in Northstar just for giggles and low and behold there is interest.

    Is the 95 and older REALLY a plug in PROM? Or is that just a guess??

    Anyone got a N* PCM that can take some detailed pictures of each IC for me? Maybe we can find out something on that it might take to make it work.

    Worse come to worse, we unsolder the flash part, put it in a real programmer and do it the old fashioned way. I just wish they wouldn't have adopted this goofy OBD2 protocols.

    Re: PCM Tuning Progam for NorthStar V8's?

    Anyone got a spare PCM to work on?

    It might be faster to pull the flash memories and then read them to get a actual code.

    You need to determine which IC's they are, what processors they are and then decipher the communication they are to use.

    But like they said, screwing up can "blow" a PCM. But, rarely is the PCM "bad', it is just a corrupt flash. So you simply toss back in your programmer and flash it back and solder it back down. The PCM is back in business.

    The fun is then breaking down the OS and figuring out which table is what, which switch setting is what and what constant is what.

    I work on hardware, I am not a software junkie. So the first part is pretty easy. Second isn't my forte....

    Owch. HP Tuners is ticked at Cadillac owners!

    http://www.hptuners.com/forum/showth...?t=9364&page=3

    Not quite sure what sent them over the edge, but I guess that is how they handle it.... Oh well.

    My guess it would take $2-$5K to do the work to break the code and get a solid definition file. Salary, PCM's, technican work to pull parts and fix things, and software guys to do the work.

    How long to break even and then how long to be profitable?

    A long time. The number of people that own N*-powered vehicles and have shown significant interest in a tune sure wouldn't be enough to motivate me as HP Tuners to get to work on it.

    Well, EFILive has done some work on the 4T80E in the 06-07 Devilles. Maybe they are next on the list!

    Everyone who is seriously interested, email TC@tunercat.com, he is the software engineer and designer of TunerCat OBD1 and 2, which 2 is now Jet Spectrum Tuner, but he still is the software guy to convince....

    Re: PCM Tuning Progam for NorthStar V8's?

    I have been talking with them and I understand why everyone won't mess with it. It would really take a pretty good overhaul of the existing program to make it work right. They do it now, but have to apply some manual processes to the .bin before they can write it back into the PCM.

    Looks like Tunercat OBD2 (now called Jet Dynamic Spectrum Tuner) IS working on it, if anyone would mess with it, they would.

    From what I gather, keep watching, support might be closer than you think. Westers CAN do it now, but the PCM must be shipped to them for it (I agree on the reason)

    Call Westers now and see what they have.
