yes, you can use a mr2 vpc the pressure sensor is the same as in the supra set you have to hard^wire it into the factory harness. you have to order the right vpc chip for your car and set the dip switches for the supra as well. pls have a look for this procedure on the www.mkiv.com by tech articles under vpc install instructions. I already bought and mount an mr2 vpc for my supra, there was no problem.
