'91 Celica Alltrac running a MS piggback

Finally got her up and running on the megasquirt, thought you might
like to hear. Its only got control of the injectors and fuel pump for
now and its having teething troubles but it runs like a dream with
alternating 2 bank injecting and narrow band EGO feedback. Got the
wideband 02 to go in asap to aid tuning.

The main issue i have at the moment is that if you run with the denso
ecu in as normal (MS still thinks it has control but doesnt, and is
still sharing all sensors) it runs fine but when i put the MS in
control it runs fine until you blip the throttle above 2Krpm, and the
denso holds timing advanced (I think) and it stays at 2Krpm
indefinitely. I THINK its from 02 feedback and the denso system trying
to control idle speeds by tweaking timing based on AFR but im not sure.
Got a few check-boxes to tick before i can say ive investigated it
thoroughly - i was just really pleased with it actually running!
