I know the RSM can be wired up to be in series between the speedo speed output and the ECU.
It can be used to de limit the car if you want.
My question is does the 'speed pulse adjust' function change the speed signal going on to the ECU, or can it be done with other settings.
Or does the RSM just dumbly send the speed signal on to the ECU from the speedo. I know it can de limit so it can't be too dumb!
I need to convert my speedo dials to mph (I'm in the UK) but when you do this it seems the ECU receives a 50% slower speed frequency signal...potentially confusing the HICAS, power steering, ABS etc.
I was hoping I can recondition the signal with the RSM back to the correct speed.
