In-car RPM, Boost, Air Fuel, etc. PSP Guage.
I figgure since alot of devices that read information off of your cars ECU (mainly OBDII) and output it through usb to a laptop, it would be posibile to input the signals through USB into the PSP and have the PSP display the infromation such as RPM, Boost, Air Fuel ratios and more. Alot of these programs just need Windows 95 to run and I belive some are even open source. The real problem is, can we get the PSP to accept information though its usb port?
