Question COPS Missfiring (99% ecu issue)

Installed Toyota COPS (wasted wiring) on my 94 NA MS2PNP with correct dwell times and, they dont get hot but i am getting mad missfires when even slightly giving gas.

The hardware is 100% in order, swapped and checked.
Current tune:


Things i tried/verified:
  • It runs normal with the stock wires.
  • The COPS hardware is 100% in order swapped and checked.
  • I tried skip pules to 1, and a higher nominal dwell but no success.
  • Base timing is correct and it works with stock ignition wires.
  • Rising edge doesn't work, car wont start.
  • Going high is correct, with going low they get hot
  • Car runs on same settings (correctly) with stock wires exept for the dwell times.
