I was just looking at the "book". There are 2 different key relearn procedures; 10 minute and 30 minute. If you replace the ECM you MUST use the 10 minute method. That is the one that requires a Tech2 or equivalent.
I did put a new, programed to my car, ECM in my 2011 without having to do any security fiddling. It was just plug and play, aside from having to re learn the crankshaft sensor. But, that was for the correct engine, year and BCM.
so I am going to buy a tech two scanner any thoughts on a clone vs a $4000.00 tool
It would be cheaper to put the right engine in than spend $4000 on a tool, hoping it will fix everything. Then resell the engine you have now. Probably even cheaper than a clone.

well looks like vector bundle say they can have it running with VIN change for 300 so I am happy with the 800 bucks I spent total for and motor and tranny that have only 76k on them and gets 4 mpg better than my old one. I still may have codes from the missing components like abs and other little things but it will pass deq and run I like it.
Thank u all for the input it was very helpful. I am sure u guys will hear from me again
The ECM doesn't know about the ABS , so you shouldn't have codes for that.
It is on the GMlan so, yes it could cause problems. The LAN is basically a token ring network; where each segment must be terminated somehow. It might not, but could.
If one of the modules on the "ring" becomes faulty the "ring" breaks at that point. I am not sure if absence would cause the same thing as a fault. But the controller is looking for digital signatures of the modules.
Too complicated for me this morning. I wish I had been partying as much as my head thinks it was.
Hello all I have posted here about two years ago I have a 07 hhr 2.2l that I put a 2010 2.2l into I used the harness from the 2010 from power distribution through out the motor. I can get it to start because I had the vatts disabled and jump the crank relay. But the TCM is not communicating also the BCM is out of the 07. I can't find any good pin outs for the cars and need help please it's a big job with out
So, the 2010 2.2 has VVT the 2007 2.2 did not, hmm I don’t think there’s even a possibility of including those.
You might get away with changing the timing chain camshaft gears from the 2010 to the 2007 .
This would eliminate the cam solenoids and the camshaft part from the VVT
I think I am confusing everyone the car starts and runs great I just need to correct the wiring differences between the years and don't have good prints
