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.

Last week I spoke to Brian, I ordered a aluminum Koyo 37mm radiator for 97 Miata. Brian, you run a first class show! It arrived the next day. It is a fully polished work of art. The welding is perfect. The fit is perfect, old radiator slipped right out, new one slipped right in. Perfect. I am very pleased. Thank you.

As you can see, i placed another order for more parts for my car. I wanted you to know that I'm pleased at how quickly the wheels/tires came, and the radiator too. Great service and response time.
