Any way around using a different motor harness and computer? I'm not afraid to hack into my body harness to make things work.

You would need to swap to an ECU that is supported by your choice of tuning software. The ECU in 07-10 2.2L cobalts is supported by EFILive and HPTuners. I am unsure of all of the differences between the 05-06 cobalts versus 07+ other than the 05-06 models do not have a camshaft position sensor where 07+ models do. Hopefully someone who is more knowledgable can drop in and help.

With a 07 computer could you possibly just plug in the camshaft sensor and tune it out?
But doesn't the 07 run the timing off of it?
CBM said: "Delphi MEFI 5 computer and one of our custom harnesses" but it's 1500 for the harness and ecm and 1000 for the cable to tune it.

What does the cps actually do on the 07+? Could you just plug the sensor into the computer and zip tie it off somewhere and change its values to run right?
I also forgot the 07+ is coil on plug. Ughh

Your next issue could be the differences in transmission control. I am not sure if there is a difference; ie: a separate transmission control unit or is it controlled by the ecu/pcm.
Edit: just saw recent post. You might be able to get away with leaving the cam sensor unplugged and tune it out. Not sure.

07+ models do use the camshaft sensor along with the crankshaft sensor for timing the rotating assembly. As mentioned, I would avoid ebay kits and the like. Your best bet might be to find a junked 07-10 2.2 to take the electronics and harness from it along with the cylinder head.

I think I'm going to contact aem about the fic. As I already have a trifecta tune that works without any problems besides it's not giving the full potential. A local shop to me is a aem dealer so maybe they can dyno tune it also.

Joe, have you had to contact Trifecta lately? I've sent a few emails to them and Weller but never get a response. They no longer list our cars on their site so I think we got the shaft.

I think they stopped when Vince left/retired.
If you need a s/c tune I think you might beable to flash somebody else's tune?

It was mentioned on here they stopped supporting it around new years this year. I guess that explains why repeated emails, Facebook messages, etc sent to both Vince and Steve have gone unanswered. Murphy's law it happens when I have a forged motor and supporting mods.
That seriously makes me question ever buying one of their tunes for the models they support now if they just drop you like that.

I thought about that but for some reason thought they were coded with the Vin number. I could check around I'd anyone has a L61 tune for a stock or 2.9 pulley. That is assuming the flash doesn't brick my ecu and I can flash it back to stock if it doesn't work. It's either that or f/ic8...

Another reason why HP Tuners is better lol
