Trouble loading 2002 OS in 1999 PCM

[Beer99C5]

I have V1 Commercial and upgraded to V2. The V2 is up and running and I transferred the licenses to the V2.

I am trying to upload a converted 2002 Vette OS to my 99, I believe I should hit "Program PCM with currently loaded Operating System and Calibration" to do this, however it is not selectable (greyed out)...

[kbracing96]

My V2 has done that a time or too. Doesn't seem to recognize its a commercial version. Try unplugging and repulging everything, maybe even close down the software and restarting it. Usually works for mine.

[Beer99C5]

Yep that worked...

Thanks kbracing96
Car even starts with the New OS...

had to reset the oil life after the update

But now I have a DTC 1336 Crank Position CKP System Variation Not Learned

[kbracing96]

Just use the scan tool bidirectionals to do the CKP relearn.

[Beer99C5]

That was not so bad, did the relearn (it stumbled at about 3800-4000 RPM and the DTC is cleared).

Took it out and did about 40 miles no codes and drives fine...

So next is the Cal only flash with OS5?

I am getting close to wrapping this thing up.

First do a full flash of COS5 (02020005).
Then do a cal only flash from your saved 2002 OS (12212156).
Then edit the out-of-range values to some sane value (or to max-1 for some).

LOL damn I gotz it backwards you get me about once a year there Joe doing something ass backwards fortunately i did not try to merge em yet

[joecar]

[Beer99C5]

OK not getting anywhere...I did various combinations

Base 2002 (full OS load) with the COS 5 (cal only) loaded cal only goes into reduced power mode on start up

Loading the COS 5 (full OS load) first then the 2002 tune cal only yeilds no start.

After a quick look, some comments on the second tune:
- looks like MAF is enabled, increase C2911.
- B3547 is very rich at idle, and lean at high MAP values.
- B5913 has too much advance for boost, seems to me.
- C6301 doesn't look right for 2 bar MAP sensor (but I'm not sure).
