Tach Signal generator for Fuel Injection

Installed Edelbrock EStreet2 fuel injection on my Oldsmobile. The instructions recommended this module to generate a clean tach signal. Installed easily and the car started right up after the installation of the module and the fuel injection system. I am using an HEI distributor with the HEAT module and MSD coil, cap, and rotor. I haven't driven the car for long periods of time yet, so far everything has been excellent.

Easy installation!

Installation can't be easier and the programming of the rev limiter is super simple.
