So I did Dave W's conversion with the ZIF chip on my '87 R10. Burned a new stock chip as well as a new tuned chip. And it ran great...for about 10 minutes. Then the SES light started flickering and I could only keep it running by giving it throttle at all times. I was trying to back the camper between my garage and the neighbors fence. Super fun! So obviously I screwed something up and while I could see about getting another ECM and trying again, I figured I'd see if anyone had one that they no longer needed. Thanks!
