G'day all, I'm an old fart having a go at this new technology so have patience with my stupid questions .
I'm thinking of using the LS ECU to power my !uz in my 37 chev. Wanting to use the original crank and cam sensors if possible which are VR sensors and LS has Hall. Is there a way of using these with maybe a small circuit change or similar and using the 36-1 reluctor wheel that is already fitted? I noticed that the 24 tooth reluctor on the early LS is double sided with a starnge tooth configuration. If need be i can make a normal evenly spaced 24 tooth reluctor and adapt the genuine hall sensor but don't know if that would work. I think i've worked out a way to use the trans control to change the solenoids in the toyota trans with a couple of relays as the Toyota trans is positive switched where GM is negative (or visa versa. My memory aint what it used to be).
it means you loose sequential injection, but from reports batch fire to sequential doesnt make much of a difference. Up to you if this is acceptable or not.
You need to keep the standard but unique 24 tooth pattern.
If you use the factory dual wheel, you'll need the OEM sensor as well well. You can get aftermarkets single wheels and sensors to adapt to the Toyota crankshaft. That's the best way then you will have the 8 coils.
Further to that, if you can replicate the OEM cam signal which is a 50% duty cycle to indicate which bank is active you'll then retain sequential spark and injection.

Thanks Dylan, i read all the answers before but they really hadn't answered the question to my understanding. Your reply now makes more sense. I have no problem making a a single wheel trigger to suit the toyota engine. I'm sure i could make something for the cam as well to duplicate the signal and i could possibly use the LS cam sensor for that. I just didn't know if the crank sensor would work correctly with a single plain 24 tooth wheel. Thats why i asked about using the VR sensor. I know they give a different signal but have read that their are signal converters around. Just don't know if they would work in this application or not. I will see if i gan find a hall sensor that i can adapt to fit and work. Thanks again for your input
Without cam signal on 24x, I think sequential still works, but will have extended crank until pcm figures out which firing sequence to use to get engine running.
