Running fuel only with 36 tooth crank trigger

Post by 1986mitz »

Hello just trying to get my settings right . Manual has a lot of info , but is not specific to my setup. I'm trying to control fuel only with 36-1 trigger wheel with hall sender to vr+. I was told in base ignition settings to put deg to zero and skip pulses to 1. In dual spark option select single crank trigger and then go to advanced options and enter 36 to 1 wheel.. Options in advanced will not burn and I got no rpm?? Any help would b great thanks . An example of settings of similar setup would be cool.. I have version 3.83 and have a 4 cylinder engine thanks.

You will need to set this up as if you were controlling the ignition - just leave the ignition outputs disconnected.

Thanks Matt. so I finally got to drive my Microsquirted Montero with a turbo.. I was pretty excited to finally roll down the road. I put the auto tune on and started driving. it worked pretty well till my electric fans came on. then it died and would not restart. Possible noise, not sure. let it sit for a while then started and ran decent till fan came on again. heres my Msq. I m going to wrap my hall sensor in foil tape and check alternator output. I may need to up the amps its the original 1986 alt. noticed when I start turning on lights and other consumers , the micro gets funky... what you think? Thanks for any replies.

So I ditched the hall sensor and installed a ford vr sensor and now my rpm signal is solid.
