I have just fitted an 06 TD42ti motor into my GQ and just curious if anyone has a work around for the TCV on the pump and tacho sensor?

I don’t have the factory ECU, using a GQ loom, have read about using a Hobbs switch to “trick” the TCV and using a spacer on a GQ tacho sensor but can’t find any real information about either.

I will eventually be replacing the pump with a full mechanical pump but not flush with cash either so looking for a temporary work around, thanks in advance....
