Acewell RPM ford zetec
Dooey99 - 12/10/13 at 11:42 AM

Has anyone used a acewell dash on a zetec engine I guess people have but how do I wire in the rpm sensor? It shows on the destructions to wie I to the switched side on the Coil pack but there is two switched wires on the coil pack so do I wire it to both? Or it also says wrap it round the coil lead which doesn't help as that is for a single cylinder engine

Please help me.

I wired mine into the ECU.. MS then Omex no problem.

At the minute I'm running an old zetec ECU so has two outputs controlling the coil pack plus the power, I look to run a nodiz pro in later life but would like to get in running how it is at the minute :/

I can't remember how I did mine - I have an Acewell and Megajolt.

I think I wired it to one of the two coil pack wires and then adjusted the settings in the Acewell to make it read correctly.

Ah right well I have found a wire that comes out of the ECU that goes to the standard tachometer and have wired it into that sadly I'm still waiting for exhaust parts so cannot run my engine to test it.

Sorry to revive an old thread but did that work, I'm looking at the Acewell dashes and will be using the standard Zetec ECU and want to know if I can wire up to the sensors out of the standard ECU?

Thanks

The 4 cylinder Ford coil pack is effectively two wasted spark coils with control trnasitor for each oil. The connector has 3 wires the central wire is +12v supply the two wires on either side are the control signal wires for the pairs of comanion cylinders 1&4 and 2&3 respectively.

Each signal wire will be pulsed once per complete revolution of the engine.

Ok, but how would that get wired up? I was hoping that the OP had managed to wire up through the tacho wire that comes from the ECU rather than coil pack. Would wrapping the indication wire around one of the coil wires do the job then and would it need to be screened off from the other to avoid interference?

If it helps, i had a blacktop zetec running on standard ECU and had an acewell dash fitted and working.
I can't actually remember where i wired it up to, but the suggestion i've had is pin48 for the blacktop.

This link from wasa has all the pinouts for the blacktop and silvertop:

That is excatly what I did, Pin 48 on the ECU and set the Acewell dash to 2 pulses per 1 revolution.
