NOW,

I have replaced my broken EPIC diesel pump with a Bosch.... long story, short ending it WORKS!

However the tacho drops away at 3000rpm (normal for this conversion) EXCEPT......

My wife used to drive the car (with her spare key) and the tacho would work all the way up to 4500rpm!!!!!

So, I have 3 keys, 2 original and one recut key.

When I drive with the recut key the tacho works perfectly!!!! With the other keys it doesn't.....


Can anyone explain that to me???
