Ken - you don't need the ECU connected to just have a play with the programs and get a feel for what they are capable of. When I opened Interpreter, then clicked "FILE" then "CHANNEL NAMES" I just couldn't believe the datalogging capabilities. I was like a kid at Christmas as I went through all the sensors that I'm putting around the car.....
The more I look around the software, the more I find! If I can't work it out, I send an email to Motec Tech, and have a reply within a couple of hours - their tech service is second to none.
I've sent you a Private Message, lest I be accused of turning this forum into a business.....
See you,
Craig
