Hey guys my 87 Toyota Levin is running a go tech pro x ecu just wondering has anybody running this ecu had crank sensor issues causing problems, I've been told by a mechanic that if its not my crank sensor gone wrong I will be looking at a new ecu, just wanted to no if any of you guys have any ideas or expericend any similar issues ??

What crank sensor setup are you using ?? Toothed wheel on the crank ?? Distributor ??
Crank sensor signals are best tested with an oscilloscope as they are usually very low
voltage. The sensor cable needs to be shielded, and should not be run close to high
voltage ignition wires. If you have a toothed wheel on the crank, the clearance between
the pickup and the wheel must be set correctly.
