That's because your trying to use an mpi rev counter on a earlier single coil ignition system it wasn't designed for and hence reads double the actual revs.

thanks for the reply is there a fix to this issue ?

[Fast Ivan]

as above; the mpi uses a wasted spark system so the rev gauge reads double

good news is there is a way round it, see here http://www.theminifo...pi-rev-counter/

Would it do the same when using megajolt? Read double?

[Fast Ivan]

I believe megajolt would also be wasted spark, so the mpi gauge should work fine, not done it though, just in theory it should be fine

[bluemini1979]

Yes your right the megajolt is a wasted spark. I've got a nos set of mpi magnolia clocks. I didn't want to have to break them to be able to use them out of an mpi. So I will use tem with my megajolt on the supercharged mini I'm building

I would assume the purchase of SPi gauges would sort this.....
