BOFI Racing 36-2 Trigger Wheel for Mazda MX-5 NA NB

With the later 1.8 engines (NB1/NB2) they come with both a crank trigger and a cam trigger. This is used to give the most accurate position of the engine at all points, however, the stock setup comes with a 4 point trigger wheel – which while in an OEM capacity works very well, when using aftermarket ECUs we’re able to improve on this.

Using a 36-2 wheel we have even more fine control of the engine and information about its position. It allows the car to start faster, respond faster to changes in load and gives far better timing control and resolution at every rpm, with the VVT engines using this type of wheel far better control over the VVT solenoid and position is possible.

A highly recommended upgrade for any car running forced induction.

Compatible with Long nose 1.6 engines and all 1.8 engines using all Megasquirt ECUs and Motorsport Electronics ME221/442 Gen2 ECUs. When installed, the missing teeth should be oriented to the left of TDC (counter clockwise from TDC).

Direct bolt-on upgrade for stock harmonic dampers currently fitted with a 4 tooth trigger wheel and Fluidampr’s. Not compatible with ATI SuperDampers.
