There might be a fairly expensive route, IF Apex makes a Power FC for the 7M. I don't know where to find out if they have one though. Guess you could ask a shop. On my S13 SR swap it would show temp, timing, voltage, rpm, speed, injector duty, knock, and some other stuff. You can view up to 8 things at once. The FC itself doesn't log data.. for that you buy the Datalogit program, which I believe is made in Austrailia. It plugs between the FC and commander and can log everything. You can basically have a fully programmable ECU w/ datalogger for around $1400. A lot of money, but remember you don't have to modify ANYTHING to use a Power FC. It's 100% plug n play. Even retains A/C controls for the girls.
Just remember, I DON'T KNOW if there's a Power FC for this car. They used to have an application list on their website but I can't find it now, if they have it.
