Its similar to the ProEFI. They are targeting MKiV Supra as the number 1 plug and play application, with R35 coming a short time later. Its at least 6-9 months away for us.
It has the Ethanol Sensor input, Traction control, closed loop O2 sensors ect.. I spoke with some of the engineers at PRI, its a nice box.
Edit. Its not really cheap.
honestly the stock ECU will be dominated by EcuTek and Cobb. no real reason to go anything else due to the limited capabilties of the current crop of choices.Always good to see increased efficiency from stand alones. Has there been anyone who has been working directly on the car's ECU? Not the usual suspects ie Mine's, I am taking about some other tuner...
