Really need some help wiring an ABF tdc sensor to a megasquirt. on the db37 i have the following pin 24 pin 1 pin 2 i believe 24 to be a signal wire and pin 1 and 2 to be earths? dont know where to wire them to though. any ideas?
You can use the ABF hall sensor as long as you configure the MS board to suit, its been a while since i did mine but looking at this diagram you should be using pins 24 & 25 and wire pin 1 from the sensor to earth. not a great pic but left to right 1-2-3?
hmm not sure thats right. its showing v2.2. This is v3.0. pin 2 +earth, pin24 signal and a voltage ref.
Things may have moved on, it was 2007 when i did this work I have also just found an old post of mine on the MSEXTRA forum saying: On the sensor, Pin 1 +12v in Pin 2 Signal out Pin 3 Gnd Might be best to check with toyotec......
Thanks for the help so far guys, i guess i need to send voltage to the crank sensor then this is where i was confused the board is modded as per toyotecs sticky which says i can use 5v instead of 12v.
Once the board mods are complete, then follow Steve's pin outs on the sensor. MS1/2 ver 3 PCB for Hall CRKPS. G28 Pin 1 to MS 'TPS 5v Ref' Pin 26 G28 Pin 2 to MS 'TACH SIG' Pin 24 G28 Pin 3 to MS GNDs Pin 7-11 **The 'How to' thread has been now updated with this diagram.
