Awesome, consider me proven wrong!Bingus wrote:Here is the bin I pulled from the 07 P12b I have. It is indeed 2MB.
It also took a lot longer to read due to failures - wondering if the resistor trick would help. I'm surprised at how unstable the P12b read was compared to the P12 I have.

Re: PCM Hammer Release 021
Yep the 07 is the p12b 2mb. I was able to reproduce this last night and I think the timeout is borderline too short for the larger sectors on the amd flash chip with the xpro timeout calcs. I'll try and get this sorted soon and send you a test build. Can you confirm the 07 actually has 2MB? GM talk...

Re: P04 R&W Testing
P10: MY 02-05 P12: MY 04-07 For P04/05, I'm not as familiar as the others on here with these PCMs. So you are telling me that there is an overlap of years where the vehicle COULD have EITHER a P10 OR a P12? (04-05) The P04 is a FWD (3100, 3400, 3800) V6 PCM up to 2005 or so, while the P05 seems to ...

Re: P04 R&W Testing
I am HOPING to go to the local JY this Saturday and get a few PCMs. Anyone care to help me with models, years, and powertrains to look for? ALSO, does anyone KNOW what the cutoff year was for the P10, P12a, and P12b? Thanks, Mike P10: MY 02-05 P12: MY 04-07 (P12a=1MB - I believe P12b/2MB is more a ...

Re: Getting started with PCM hammer
Can you confirm you've converted the factory PCM to a P01/P59 PCM with this swap? A 99 Yukon 5.7+60E would have come with a Vortec BlackBox PCM, which isn't supported by PCMHammer at this time.

Re: PCM Hammer P10 development
I've got a few P10s and would be happy to test. Send me a link to a version of PCM Hammer (or Github link?) with the changes and I can test!

Re: What PCM is this
If you can (know some eBay listings have 1 bad pic), look at the connectors: P12s have small - big - small. E67s have small - big - big.

Re: What PCM is this
That's exactly what it's out of. My 08 TrailBlazer 6.0 has the same p/n, OS should be 12618164.Gampy wrote:Thank you!
Bummer ... They said it's out of an 08 Trailblazer 4.2, connectors didn't look right, I didn't order it.
This is an E67, P12 was 06-07 only.

Re: PCM Hammer P12 development
So if I read that correctly then the P12 was used on 4,5, and 6 cylinder engines. Which would be really interesting they all used a common Operating System with different calibrations like the P01/P59 did. Yes, all Atlas family engines (I4/I5/I6, 2.8/2.9/3.5/3.7/4.2L displacements) used the P12 at ...

Re: Help identifying Motorola chip
Maybe this is the main or secondary/DBW one? I believe there are 2 chips that are really CPUs in the P12 (and P10). The main and secondary, with secondary being the DBW/electronic throttle controller. Both are in the PCM, similar to how all Gen IV+ ECMs do DBW.
