I loaded the Trifecta Tune in my 2009 HHR SS Automatic . Now it will not start and it has two Errors that im sure is the clue. PO807 and PO80A 05E8 History Current Stored Clutch Position Not Learned... PO807 dev 05E8 History Current Clutch Position Sensor Circuit Low..

Im thinking they gave me a Tune for a Standard not an Automatic. Always have a second car to do this , im stuck . Any help with this is appreciated

 

Sorry. We can't help.
You need to contact the Trifecta vendor you bought the tune from.

 

Push the go back button.

I guess you could get a used ECM programmed to your VIN. That would probably take just as long.

If they sent the cable and the program to flash, I would hope they included a "save old firmware" provision for just such events.

 

Better yet, i have a brand new never used ECM for sell in the classified section, for the same price the a used ECM normally goes for...

I believe in Mr Murphy's laws, that's why I have a backup ECM, ready to go. which has my stock GMPP program on it ..
Whenever I take my 'buggy' in for factoryr service, I 'pop' this ECM back in, incase it's needed for proper factory troubleshooting.

This came in handy a couple of months ago when I had an issue with my doors unlocking at random times when driving. My extended warranty was expiring soon, so I took it in for service. They thought for sure that it would turn out to be an ECM problem, and had ordered a new one before I arrived. It turned out to be a loose ground. They stated that there was an updated ECM 'flash' available, & updated my ECM also. Since they had no use for the new ECM that they had ordered, they offered it to me for $200, so I took it incase anyone needed one in the future. You never know when they will stop selling parts for our 'buggy'...
