J-M kujala,
I built my MS2 V3 all by myself and to be honest I never really adjust any pots from the package from DIYAutotune. At first I fired up the engine with MS3 V2 in "Fuel only", I left the distributor and the toyota igniter do the sparks and just connected "Pin #2" to -coil only.
Once its all fired up and be able to tweak with the idling fuel map, only then I connected Pin 36 to -coil and disconnect the wire from the Toyota Igniter and run a 1K ohm resistor across it.
The diagram below is what I did to my wiring
This trick should work with any dumb ignitor, not nessesary must be Toyota ignitor.
Hope that help.
Cheers
CHB
