Id still love to have P10 full flashing, the P12s got it!! Want to run my 02 P10 on an 04-05 OS for more fan parameters. And paying the dealer $75 bucks if it goes wrong both ways doesnt make much sense, Id probably have to buy another PCM and use another license (another 100).

How close are the 2 OSs , I mean one has SD tuning and the P12 has MAF .
Would that pose a problem ? Would be interesting to see if it could be done .
Yeah the OS I am trying to get a hold of is a updated OS that has some trans and other things changed by GM for the better so they say .

Requested P12 file is below.

They're not close at all, the P10 is a lot like the 99-02 4cyl PCMs vs the P12 is like the E40. I say "like" not exact.

Bummer, no way to reprogram the ETC CPUs memory? I wonder if an 05 P10 file will run my 02 P10 with the stock wiring...might be time to buy another P10 if I end up keeping it longer than December.

Ah, but that ones easy because its an E67!!! haha:hihi::fluffy: Have to challenge you some times!

Weird though, if I keep the 02 Ill buy a few extra P10s and have them flashed with at least an 05 cal to see if I can get it to work with the 02 electronics. Last I checked just the emissions stuff is different, or maybe Ill borrow a PCM from a friend and see if I can make it work first.

Think here soon once I order a WBO2 Ill start tuning the E67, hope its as easy as the tutorial makes it out to be haha!

The SS will get its set of LSx goodies over the next few years as I can afford to do it, my eventual goal with a Maggie TVS blower is 450-500awtq hehe. Plus cam and all the bolt ons.
