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.

Everything that I've read says to drive the tach via GPIO. You might need to futz with it a bit to get it to work.
There's an option under Tacho Options called "Tacho M" which is the multiplier. |

The wiki says that 95.5 - 05 cars need a tach circuit. On my 94, the GPIO tach is wired to the OEM connector.
Sorry I'm not familiar with the NBs as much! |
Factory tachometer is driven from one of the GPIOs. A pullup resistor is required. All of this is included in our PnP package.
