I'm going to be installing 60 lb injectors in a 2000 SS when I procharge it. I and ran into an issue previously on a 99 SS where I needed a new .cax file so I could see B9021 min transient pulsewidth so I could keep the car from running pig rich. Is this .cax file available? I uploaded my existing NA tune that I will need the cax file for.
Calibration is 9385741 and OS is 09381344
Attachment 20273
OS 09381344 is not listed here (see post #12): need-B9021-for-01250003
Would this PCM be able to run say a 2002 F-car OS (e.g. 12212156)...?
Thanks for the response Joe. I have to admit I've tuned plenty of cars but I've never done the update to an 02 OS on any of them. I assume from reading that there's no reason it wouldn't work assuming someone can walk me through it. Last time I had the same issue with a 99 SS I simply uploaded the file and someone sent me back a cax file.Quote:

( I've run into a 1999 F-car PCM/LS1/4L60E transplant, and the PCM was not compatible with 12212156 or 12202088 )
If it does flash, then you have to edit into the 12212156 tune file all the changes from the 09381344 file (if the 09381344 file was already tuned and running good)...
or you could simply run the 12212156 file as is, and do some tuning on it (you will still have to change some things like A4 shift points and speedo parameters, DTC's, and a few other things).
Last time you probably had an OS that had a B9021 cax defined for it.
So basically try and upload an 02 OS and if it takes it than makes all my changes to the 02 OS. Then do I use the cax files from that other thread to see the min injector pulse table to run the 60 lb injectors?
Yes, if you manage to load 12212156, then you go ahead and use the B9021 cax for it.
Cool I'll give it a shot either tomorrow or Thursday, we have a big hurricane hitting this week so I should have some time to see if it takes the 02 OS :online2long:Quote:

So I just tried loading a stock 02 camaro SS A4 file I had (1212156) and I got an error that said "The files operating system number: 1212156, is not compatible with the PCM's operating system number: 09381344." What do i do now? I was doing a calibration only flash, do I need to do a operating system and calibration flash? I feel like the answer is yes, but want to confirm.
