Is it possible to read the PCMs with EFI even though they're not supported? If so, you want any more files? I could probably pick up a few for you.

It's embarassing for me. Actually Jesse (Wait4me) has some of the 2007 P12's heading my way too, so we can add support for them too. Talk about a one year wonder PCM the 2007 P12. What was GM thinking?Quote:

Sweet to hear about the 08 LL8, Im working on seeing if I can do a PCM swap from my 02 P10 to an 08 E67, maybe our neverending search for boost using a GM PCM is over???
And Ive heard that 06 P12s have 1/2 the memory of the 07 P12s, I have no idea wtf GM was thinking on that one.
The P10 code is efficient, maybe too efficient? Interesting... But thats weird of GM to make the V6 code so different than their norm, but then again the 07 P12 comes to mind...lol
If anyone has an 08 TrailBlazer I6 .tun file, Id love to see it! :D
I have many, many v6 files as well, let me know if there is anything specific you need.Quote:

There is another issue with the 01-03 (maybe 04+ as well, but I haven't verified anything) pcm's that I can find no parameter mapped so far that fixes it. When running without a rear o2 sensor, the pcm will set both long term and short term fuel trims to maximum positive, adding way to much fuel, (I've seen cars hit 10.x:1 afr when cruising due to this), the issue only appears in closed loop and while at a steady throttle. The only way to fix it is to run a rear o2 (a simulator doesn't even fix it all the time), however, many of us run open headers at the track, and this will screw with our WOT fueling, and cause stalling while in the staging lanes. Finding out what causes that will be of great help. Running a 98-00 OS instead causes 16 degrees of burst knock, which is completely unacceptable, again probably due to parameters we don't have mapped out.
This is the issue with the P10, the code is tight, makes adding things in a little tougher. I think your better bet would be to fit a P12, not an E67. Remember the P12 can handle boost as is.Quote:

The thing you have to remember with computers, they can't think, they only do what they are told, so if it is going to full + trim with no rear O2 it is either a calibration or a code decision, which means it could be stopped.

GM states in their tech update for 07 that the extra 1MB of memory was for emission purposes, BS IMO.
The P12 can handle boost? (Looks like and E38 or E67 from the outside anyway, dont know what the internal differences are)
Really...I have the pinouts for an 02 P10, 06 P12 and 08 E67, Ill compare the P12 vs E67 too now. Why would you recommend a P12 vs E67, there should be more E67s floating around? And do the P12s have the boost VE table, the E67 should have them there already (at least from what Ive seen on the other E67 .tun files). Any way I can get an 02-05 I6 to run boost and Ill be a very happy man, plus a ton of others will be too.
IE7??? :( FireFox! :)
(P.S. You can always email me that TB file, email is in my profile. :) )
After driving my Mrs' 2002 3.4L, thease features are sorely need:
- being able to disable VATS;
- being able to lock TCC in 3rd;
- being able to disable fan run-on after turning off AC.
Ross V6 support would be awesome!!!!! :D
one of my buddy's is doing a custom 3.8 (series II) swap into his 1989 toyota rock crawler/offroad/dailer driver pickup. We dont even need tuning really, but are really looking forward to the simple things such as VATS and DTC enablers...
thanks

This all sounds really good for the US crowd but what about the Aussie V6 support...young Ross?
Don't let them Bosch PCM's scare you off now...:)
At what year model did the Aussie Holden V6 start using Bosch PCM's?
I like the V6 operating systems that have switched s/c options and map scaling up to 140 kpa. For a OEM operating system this makes things a little interesting.
I think there is more potential then people release in V6 support.
Does anybody now if there is a V6 operating system that uses a 1220411 PCM?
Mick
Mick, the 3.8L in the US and the Aussie 3.8L PCM are totally different, the US one pretty much has the LS1 hardware, the Aussie one (as you know) uses the old Delco 68HC11 based PCM's.Quote:
