I am thinking about buying the Crane HI-6M to replace the TB V on my 1998 HP500's that are now 620HP. Does anyone know if the merc knock sensor and module are compatable with the Crane ignition?
The Crane box has a brown wire that will activate the retard mode when grounded, the merc module also has a wire that goes from the knock module to the ignition module that triggers the retard. I am not sure if that trigger wire on the merc igniton grounds for retad or not, this is the same circut that you ground to set the timing on the TB V. Thanks in advance . Jeff

904-258-6174 Crane. Hope this number is still good.

Ive really had good success with their tech support.

Just curious on the reason for the change? Rev limiter? Reason I'm asking is that I have thought of doing this myself.

This has been a couple of years ago but I witnessed an independent test of ignition boxes. The Crane was impressive to say the least.

Scott,
The rev limiter is the main reason.
Chris,
Thanks for the feedback on the crane box.

randy at cobra has them and the coils that go with. he also has a trick stainless bracket to mount the works. it really a clean set up even has a built in engine lifting ring. cranes wires are also great 25 ohms of resisitance per foot.

ratman,
I was going to fabricate a bracket to mount them to the back of the cylinder head, but crane says not to mount them on the engine.

Wags, do you mind my asking what you did to your HP500's to get another 100 hp????
