↑ Return to Supra


The Legendary MKIV Toyota Supra has two ECU options to choose from for the Manual transmission cars. The Pro128 with all the bells and whistles or the Pro112. While the Pro128 gives more I/O capability, the Pro112 offers a faster CPU and all tables and options live calibratable! Automatic Supra’s will need the Pro128 for it’s transmission control capabilities

We are very fortunate to have some of the best shops and tuners in the country to refer our customers to!

These two videos are of Zach Webb’s Stock engine with a single PT6766 turbo and a Pro128 on flex fuel.
Going over 200mph in the standing mile on a stock engine…VERY IMPRESSIVE!
At the dragstrip on drag radials and the ProEFI Traction Control, runs an impressive 10.5! Hard to believe
they will take that kind of punishment on a stock engine! Read his testimonial on his cross country trip HERE!
