I would double check the repin job you did on the dizzy for starters, your problem will lay somewhere in the wiring

I bet if you used a obd0 PR4 ecu it would probably run just fine. Both ecu's youre using are having a hard time figuring out the b18 distributor signals. the pickup gears inside the b18 distributor differ from that of a sohc mpfi and dpfi. try and borrow a PR4 ecu and see if it cure your problem. also better to use an obd0 distributor with obd0 ecu. Hope this helps you.

I have a D16Y7 ef and smokes a lot. I think the sensor detects no map that I connect and disconnect and nothing happens
