ls3 into xlr which tune file to start from?

[jlaw]

put an ls3 into my xlr that has a e67 pcm, to get this thing running should I modify a zr1 tune file or tbss tune file not sure if the 6.0 runs similar enough but the zr1 would have to be altered a lot. I should note that I used the ls9 pin out. any help or point in the right direction greatly appreciated.

An LS2 tune is going to get you a good starting point. Compare with LS3 tune and adjust as needed.

I believe now (playing with every car that had the e67) that I need the zr1 tune, its the only car that operates on the e67 that can operate the ls3 and match the transmission OS ID the xlr has. Why isn't the zr1 not available in the tune repository? would someone be kind enough to send it to me?

apply the correct injector data and it will be fine

hate to ask for more clarification... do you mean just change the injector tables on the xlr stock file? the northstar has a different firing order than the ls so I cant see how that would work.

^ no that will not work. i was under the impression LS3 with its PCM
