Product Description

Add a crankshaft position sensor to your engine with our laser cut 36-1 crank trigger wheel. This trigger wheel is 6 3/4″ in diameter and 1/8″ thick, with a 1/2″ diameter center hole (with plenty of room to enlarge it for larger crank bolts) and eight radial locating slots 1/4″ wide. The teeth are 1/4″ high, so this fits crankshaft pulleys up to 6 1/4″ in diameter. It also has a balance hole in it for smooth balanced rotation. We designed this wheel to fit most modern engines with average sized crank pulleys.

    Perdon, no vi que querias swapear un LS1, a mi punto de vista si vas a hacer todos los arreglos para distributor less, no tiene caso usar tu TBI es mejor usar el intake del LS1.

What MegaSquirt versions does this trigger wheel work with?

  • MS1/Extra, MS2/Extra, MS2 Bowling & Grippo, and MS3 firmware all have support for the 36-1 pattern. Some of the traditional MegaSquirt versions may require hardware mods. "Pro" wire in systems like the MS3-Pro and MicroSquirt can use this with no internal ECU mods.

What cylinder counts can this be used with?

  • MegaSquirt code supports using a 36-1 pattern for 1, 2, 3, 4, 6, 8, and 12 cylinder engines. The latest MS3 code is also capable of running this on 7 cylinder radial engines. 5 or 10 cylinder engines require a tooth count divisible by 5.

Can this be used with a non-MegaSquirt ECU?

  • Many other ECUs support a 36-1 pattern, although we have not tested our trigger wheels or sensors with them. Consult your ECU documentation for details.

How do I measure what size trigger wheel I need?

Can this wheel be bored out to make a ring shaped trigger wheel?

  • If you need to bore it out for a larger size than a typical crank bolt diameter, we recommend using one of our unslotted trigger wheels instead.

Can trigger wheels be ordered in custom diameters or with mounting holes pre-drilled?

  • We are not able to deliver custom trigger wheels with a reasonable cost or turnaround time. Our current lineup can be adapted to most engines with some fabrication.
