I've fitted a 20V 4AGE in my AE86 so now I've got it running using VEMS. I'm close to have the diagram for the harness done but I'm not quite sure how to run the trigger.
I would like to use the sensors in the distributer. Its got three sensors: One has 24 teeth and the others share one and is 180 degrees apart. Some say 12 -1 others 24 +1. Anybody got either of these working or having any opinions on the matter? Or should I just run a 36 -1 wheel on then crank pulley?
Don't think it's usable, i've done something similar to this to a 16V to have 36-1 timing:

Or talk to Gintsk, scroll down and you'll see:
Toyota AE 86. GT25 bb turbo. Fully sequencial on stock 24+1 VR sensors. Active COPs from VAG driven from stepper chip. For drift.

I'll try making it work with the 24+1 setup first. If this fails I'll go 36-1.

My harness is just about done. I need to wire up the wideband sensor and its all done. This is my most recent pic:
I'll be running COPs from a 1ZZFE Avensis but I'm not sure if I can run the stock revcounter using their tach signal
(Found on a miata forum)
1 ground
2 trigger
3 tach
4 +12V
Any thoughts?
