So i swapped a d16y8 into my EG back in may. IT still does not run right. The motor is converted to obd1 using the EG's dizzy, alt, and ecu. The ecu i suspect is the problem. The car turns over 10 to 15 times before it starts. Also when it starts, it runs real rough until it gets warmed up. I adjusted the idle a little bit and that helped some. I'm guessing the obd1 ecu designed to run the d15b is not sending the d16y8 the correct information to make it run right. The reason i have always shot this theory down is it runs perfect after it warms up. So after recently getting promoted and having to move i now need to work on the car again. Would using the correct ECU fix this problem? Instead of using the obdII ecu with an adapter harness i want to chip the obd1 ecu and install a y8 basemap. Mainly because this is cheaper. Please dont give me the chipping is hard nonsense. I can solder, its very easy. Is there any advantage to chipping the obd1 ecu with a y8 basemap rather using the obdII ecu with an adapter besides price?
