I am a student with the University of Connecticut FSAE team and this year we are using an Adaptronic e420c, a very nice upgrade from what we used last year. One of the things we are looking to do is some very comprehensive data logging of engine parameters during the in car testing phase. According to the user manual we can log data to a PC, however it is bit impractical to have a computer in the car whenever we want to log data.
Our car is going to have at least one micro controller on it to capture data not given by the ECU such as g-force, GPS, oil pressure and maybe a few other goodies. The micro controller will either then write all of that to an SD card or transmit it wirelessly through some other gadgetry we are in the process of cooking up. We would also like to log as many of the engine parameters as we can, especially EGT. The best way for use to do that would be to directly connect the micro controller to the e420c serial port that is usually connected to a PC for tuning. However we need to know things like voltages, pin outs and data protocols in order to do that without frying a bunch of micro controllers (or ECU's) in the process.
If this is information you are willing to provide (publicly or via PM) I would certainly be willing to keep the forum updated on what we are doing the the e420c, and the car as whole in exchange.
