If anyone is going to SEMA, I would highly recommend stopping by the AEM booth. Yes, I know AEM hasn't made much for the Supra's. There is a new Engine Management System that will controll all of the stock Turbo actuators, Automatic transmission controlls and still have plenty of left over outputs to controll anything you desire. The system plugs directly into the stock wiring harness with no wiring adapters (the ECU has the supra plug built in to it). All of the functions are user definable. It has 6 times the functions of a Motec M48 Pro, built in datalogging up to 1 meg (or about 45 minutes of logging all channels). The Software is all Windows based, and very easy to use. The system will sell for under $2k complete. Absolutely nothing needs wired, cut or spliced. The stock ECU can be re-installed at any time for dealer warranties, or smog (did I say that, of course not). Believe me, this thing is bad-ass. Oh, it also comes with a complete dyno tuned base map, so start up is as easy as plugging in the stock ecu.
