L61 from an ‘07 G5 in an ‘05 Sunfire?
Thursday, July 23, 2020 1:24 PM
I have a ‘05 Sunfire that needs a new engine. ‘05 PCM does not allow tuning, is it possible to use an L61 and PCM out of a ‘07 G5?



She may not look like much...
... but she's got it where it counts kid

Where did you hear the 05 wasn't tunable?

Plenty of people have tuned with an 05 PCM.

On to the engine side of things, you would need to swap a few things over from the original engine like crank trigger and what not since they run different tooth counts.

You would still use the 05 PCM in that case.
