holley ecu
By H. Bennett
I bought this item from Amazon found it to be cheaper than from any other source I've found yet. It is made to replace the analog system ECU, (direct replacement). It is installed and seems to be working good for now, but It has some minor issues that I still have to work out. The instructions need to be better at troubleshooting problems, but For the most part it's pretty clear though.
