Thank you. You have rated this product.

The solution to getting a standard +12v square wave tach signal from the LFX motor.

The LFX does not have a standard tach signal wire because the ECM transmits all of the data to the Camaro dash via CAN bus. This poses a problem when trying to get RPMs to a tachometer gauge, display dash, etc. This tach signal adapter by Autometer is the solution. Installation requires hard wiring the adapter in-line with the pink/black power wires to the coils. The adapter provides a tach signal wire with a standardized signal that is easy for almost all aftermarket tachometers and race dashes to read.

Install notes: Ships with instructions provided by Autometer. Follow the instructions for LS series V8 engines but with the LFX you are looking for the pink/black wire supplying power to each bank of the coils.

Wanted to say thanks. The exhaust system fit perfectly, no drone at steady throttle, but a nice sound winding thru the gears. And it does sound a lot like my old Alfa. The Racing Beat lowering springs are just right. Appreciate the tech advice and the service.
