Special Offer Optical Trigger Wheel 50 mm for Nissan SR20DET or KA24DE DIYAutoTune

50 mm Optical Trigger Wheel for Nissan SR20DET or KA24DE. Convert your Nissan CAS to a more MegaSquirt-friendly arrangement with our bolt-in optical shutter wheel! This one replaces the ring of four slits with a 24-1-1 wheel that behaves like a 12-1 crank trigger. Then we added an outside slot to provide a cam sync where the 360 degree slot ring works. So you can use just the inner ring to get a rapid sync-up, or use the outer slot to allow for sequential injection or coil-on-plug. Intended for use with MS
