Have a 1990 4Runner I have put a turbo on and am using a VEMS standalone ecu. Having a buddy doing the install and although the engine is running it is breaking up above 1500 rpm. He is using the distributor to give both crank and cam signals as I went with cnp LS coils. There are a few issues to be troubleshot but I'm wondering if this configuration is giving enough resolution to the ecu with the dizzy having both a four pint wheel and a single point wheel to run both hall sensors.
The reason I didn't go with a proper crank wheel is the lack of space behind the harmonic, some LC Engineering uses magnets in the outer ring and I think that may be trouble if slippage ever occurred and the fact that I've had belts go before and I wanted access to change the belt without a sensor being in the way at the front of the pulley. I may revisit machining the rear of the harnic if necessary.

This will be interesting

I have never had a need for those extra sensors on this low horse power engine

Is this something for your stand alone ECU

More then likely you will need to source the sensors from them and build what hardware you need.

also without knowing just what kind of signal or communication protocol you need.

Like I said Interesting!!!
