I would ideally like to use the Rally Design RMD gauges in my Sylva J15. I have a Tacho output on the EMU/ECU pin (48) that runs to the instrument cluster and directly to the above unit. Can anybody tell me if the specs of the Ford EMU and a after market Tacho are compatible.

I phoned Rally Design but the chap could only quote the settings on the rear like 4/6/8 cylinders. A calibration pot. An indication that it wires on to the primary of the coil if you have one. What happens with Ford wasted spark! No reply!

I could take a simple pulse generator and work out a bit more of the picture like the number of pulses and their amplitude per 1000/revs but that would only be useful if I had the same information about the RMD gauge.

Any ideas?

I can't answer your specific question, but I use a standard fiesta rev counter with my emerald ecu on problem and have now swapped it to am after market lcd rev counter with the same ecu feed with no problems

I use an after market gauge with my eec-v I just cant remember what I set it to.

I have ETB gauges - the rev counter is connected to one of the coil pack wires, easy.
