Customer came to me with a swap he had performed. 8.1 into a 90 blazer. They did their own harness etc had a mail order co remove vats etc. The problem is they did not use the electronic throttle, so naturally it wont go over idle. Serv # 12602801 ykyw hdw # 12589161 ykyw 2007 silverado processor.
Is there any way to go in and change some parameters to make it work with a cable throttle?
