Crankshaft Trigger Wheel 36-2

Improve the MX-5’s engine management with the 36-2 trigger wheel, for precise and detailed engine timing resolution when using an aftermarket ECU. Whether you’re fitting a crankshaft sensor to an older engine or replacing the original trigger wheel, this upgrade guarantees the precision you need for optimum performance.

The 36-2-tooth sprocket replaces the factory 4-tooth timing sprocket and is compatible with all Long Nose engines (1991–2005) fitted with an 8-groove crankshaft pulley and a larger pulley bolt. It is compatible with the original crankshaft position sensors from 1999 to 2005.

Compatible with all aftermarket ECUs such as Megasquirt, ME, Hydra and others that support 36-2 trigger wheels.

It doesn't work with the standard ECU.
