I use a Toshiba 480CDT with Windows 98 to run my MICROTECH tuning program and so does a friend of mine. You will find that most nearly all ECU's will have a serial port connection and the older Lappy's suit this better. You may also need a dongle depending on your ECU choice, so try not to use a Lappy that has to have an adapter, otherwise you will have 4 inches (over exageration) of crap hanging off the back before you even attach it to your ECU!!!!

Got a spare one if your interested? $200.00. Bloody cheap for tuning and working on.

PM me if interested??
