mega jolt v4 tach out to rpm input race capture pro
Im trying to use the signal from my v4 megajolt tach out to the rpm input of the rc pro.
I recieve a signal but its not matching the one on the megajolt config screen.
any ideas how i can get this to match? It shows the rpm 200 less the the config screen?

I have an update for you guys.
Had a couple more goes at getting the rpm signal to work properly and I have solved the issue!
Firstly I had a dirty cable connection going into the rcp unit which made the signal intermittent.
Secondly the rpm settings are as follows,
for the correct rpm signal from a megajolt v4 tach out pin, using a 36 toothed trigger wheel on a 4 cyclinder engine the clock divider needs to be 128 and the pulse input per ignition event needs to be 2! NOT 36 as expected.
unsure why but these settings work for my 1.3 polo gt
now to crack utilising the oem temp sensors without any calibration data!
I will pop a picture up when ive finished the wiring of my install
