I have been using an AIM XG Log system for 3 years. I have it on both cars and there is a good number of racers using them in NER.

Jim, you can PM me if you have some specific questions or let me know what events you will be at. I am sure we can get some basic data for you to use. It also depends what sensors you have since the 90 ECU will not plug directly into to MXL.
