Trigger Wheels

DIYAutoTune.com presents our line of 36-1 trigger wheels for use with the Megasquirt. The trigger wheels are laser cut from 11 gauge (1/8″ steel) and work with Megasquirt-I with the MSnS-E code, and Megasquirt-II with either the standard or MS2/Extra code. Use the spacers to put the trigger wheel out in front of dish-type pulleys. We’ve tested these wheels with both GM and Ford style VR type crankshaft position sensors. V3.0 and higher boards can read the sensor output directly, while a V2.2 board requires a Ford EDIS external module or added VR conditioner circuit.

Trigger wheels and spacers are unpainted steel and can be painted or powder coated to match your engine compartment.
