Re: ECM swap question
The 1227747 never came in a Caprice, it is a truck ECM. You may be thinking of the 1228746 ECM, which is the stock ECM for your RS. What you can do is to obtain a Caprice chip and try it. This is the calibration data. It will eliminate VATs as the Caprice didn't have it.
It should run OK. However, the calibration will be different as the Caprice is a heavier vehicle. Won't hurt to try it. Just be sure that the chip is for the '8746 ECM, a '6965 chip won't work in the '8746 ECM.
