just the factory ECU, Ive tried one that I had to replace the caps and onother that was okay already. Timing is at 10deg BTDC with the TE1 and E1 pins bridged.
THe DLI uses 2 x factory ignitors and 2 coil packs but only uses 3 of the pins. it doesnt send a IGF signal to the ecu from the ignitors and i can only assume that the IGF comes from the DLI box. when I tried 1NZ COPS i also tries the IGF signal from them directly to the ecu but it made no difference. Using the COPS i dont have to use the ignitors at all.

One option is to do the waste/waste spark COP conversion people are doing on 20V's and that would do away with the DLI box, but that would kinda be going backwards and I dont know how much of the original stuff I need to go backwards is there.
