I'm in the process of creating a SBEC sim for my Jeep sbec. It's USB and simulates a com port. Generates IAT, CTS, CKP, CPS, MAP, and TPS signals from data supplied thru the USB/com interface. It is able to measure injector pulse width, Ignition dwell and ignition timing. The software is open protocol and open source. Kind of a one off project to convert a Jeep SBEC from a 1 bar to 2 bar without endangering my engine. However, I'd be willing to make some to help others.

Anyone interested?
