TimingLockTM Pro

The TimingLock is a simple and effective timing solution for your Ford TFI-IV vehicle. The TimingLock does not modify your ignition timing during normal driving conditions; however, upon activation, your timing is locked to the advance of your choosing. The TimingLock can be activated with a boost pressure switch, a nitrous oxide system or a toggle switch. Perfect for power adder applications. Includes a 2-step rev-limiter.


TimingLockTM

The TimingLock Pro has all of the functionality of the original TimingLock and more. The original TimingLock is no longer available for purchase, but is still supported by XPI.


UniRevTM

The UniRev is a universal multi-coil 2-step rev-limiter that is compatible with most inductive ignitions. Two independent rev-limiters are at your disposal to safely limit your engine's RPM by suppressing spark on alternating cylinders. The UniRev promotes more consistent launches and helps eliminate turbo lag.
