FAST Crank Trigger

Until now, "crank triggers" have used bulky inductive pickups always suffering the risk of broken magnets or losing magnets at high engine rpm. The new FAST crank trigger is magnet-free, using a wheel constructed from ASTM A36 grade steel that is so strong that it only needs to be .125" thick just like the OEM style crank trigger and is virtually indestructible. With the wheel being this thin, it not only weighs less but requires less space than competitors’ aluminum versions. And the FAST™ inductive sensor is also much smaller than others on the market and is hermetically sealed with the connector molded into the body. In addition, the FAST Crank Trigger is also compatible with many other EFI systems on the market.

fast crank trigger
  • Innovator of EFI technology, develops new crank triggers for Ford & Chevy, eliminating the possibility of inaccurate or inconsistent rpm measurement
  • A magnet-free device, this new piece from FAST™ includes a wheel constructed from ASTM A36 grade steel that is so strong that it only needs to be .125" thick and is virtually indestructible
  • The FAST™ inductive sensor is also much smaller than others on the market and is hermetically sealed with the connector molded into the body
  • Because the tabs are a part of the single wheel unit, there is no possibility of loss or fragmentation--as with the magnetic style trigger

HOW TO INSTALL A CRANK TRIGGER FOR USE WITH FAST XFI SEQUENTIAL OPERATION

Step 1--Remove distributor, remove gear, slide shaft out of housing. Now remove seven of the reluctors. (They are easily removed by a pair of pliers). After removed, you may want to file down the sharp edges. Now reassemble the distributor. The distributor will now be used as a cam sensor. Install distributor.

Step 2--Now you need the reluctor to line up with the magnetic pick-up in the distributor anywhere between 60 to 130 degrees before TDC. Lock the distributor down. Next, rotate engine to the max amount of ignition timing you plan to run. Now you need to line the rotor up with #1 terminal. If it does not line up, you will need an adjustable rotor or the distributor can be sent to MSD to be indexed. (Remember once you locked the distributor for the cam sync, you can not move the distributor housing.)

Step 3--To install the crank trigger, you need to position the wheel so the magnet will line up at 10 degrees before your max timing. (E.g. if you plan on 40 degrees of timing, you will need to set the trigger up at 50 degrees. The XFI needs a 10 degree heads-up. If you plan on 43 degrees max timing, you will set the trigger up at 53 degrees). The pick-up needs an air gap between 0.030-0.060.

Step 4--If you have a FAST XFI harness, the crank trigger will plug into the crank plug in the harness and if using a MSD distributor, the black and orange distributor wire goes to the black IPU plug and the black and purple wire will go to the red IPU plug. There is a ground at the cam hall effect plug and at the crank trigger plug. Make sure they are grounded.

Step 5--Connect with the FAST XFI; go to view, then open system configuration. Then change your settings to sefi (sequential fuel injection). Set your crank reference angle to what you set it to physically (step #3). Then set your ignition type to IPU (inductive pick up).
