RPM Tachometer conversion
I own a 1969 Corvette C3 and I recently converted the old 454 Big Block to a LS2 engine but the rpm gauge stopped working. I was told by the mechanic that I need to convert the rpm tachometer so it can adapt to the new system (ECU). I need help with the conversion for the rpm and what to use to connect it straight into the ECU, because when connecting it to HP Tuner, the rpm works fine, it's just the gauge. Thanks.
