Fitted some new clocks today, from an Efi car...
now it idles at 2k (on the dial), and revs off the clock ??
any ideas why, and how i can stop it ?
car is a EFi ZVH, I dont understand whats up with it

You need to change the little resistor by the coil. Its on the green wire. Not sure what you need to change it to off the top of my head. #
But I remember when we were building a Mk6 EFi Turbo, same thing happened.

seeing as you are using Efi clocks with an Mfi Loom

I have a coil pack on my car with Omex 710 management. The clocks were kept the same from when the car was MFi, all APT did was fit a resistor on the back of the clocks on 2 of the rev counter prongs

You'll probably find if you had fitted Efi clocks on yours tony it would have been alright!
Im just trying to help, without you having spend more money than need be! And a simple problem like this, you shouldnt need to!
Dont get me wrong I aint no tight git! Ill spend money where it needs to be spent like my internals!

Good Luck anyhow mate!

I think you will keep a problem with your rev counter.
The inside electronics of the MFi rev counter are different from the EFI one.
The MFi is fed by the negative lead of the coil (conventional rotor ignition).
The EFI is fed by a low tension pulse from the DIS ignition module.
Cheers.

Standard clocks can always be used on any setup. Using efi clocks with a distributor setup is more difficult. I assume you still have a distributor? Why did you change the clocks in the first place?

I too had this trouble worked out cheaper and easier in the long run just to slap in a set of std mfi clocks as by the time it takes to find someone who can do all the relative working out to tell you what size resistor to put in the circuit to get it to work anywhere half way decent you could have pissed the job off and be onto the next headache ................................. besides if you go looking hard enough you can pick a set of clocks up for a tenner or less than if you know the right ppl.
Oh then you got the next probem of which clocks will work the best with your fuel sender unit as 90spec clocks on a 88 harness just dont really work below 1/2 a tank
