Piggybacking a standalone

Post by Cummins90 »

I got tired of some of the inconsistencies of the piggybacks and when you really start pushing any engine hard you want a reliable result. So I put together an arduino set up with a single coil that works on the distributor ignition system. The ecu can be infinitely tuned and has many options ie ethanol content, boost control, launch control, rev limiters, boost cut, etc.

It is plug and play with the JTEC system. It will trip a CEL.

The stock ecu can no longer control fuel or spark. The warm up and o2 feedback are done through the arduino.
