EMS-4 tach problem
I am still having problems with my tach. I am pretty sure my tach is being driven directly from the crank sensor rather than from the ECU. Per the ECU my idle is around 1000 and the tach reads 2100. Can someone please give me some guidance to correct this whether going through gpio or putting in a resistor is the best way.
