I was wondering if there's any type of device that can be hooked up to the cars to record or display telementry data such as throttle position, transmission fluid temperature, exhaust temperature, A/F ratio, differential temperature, intake temperature, fuel flow rate, oil pressure, etc.
I know COBBTUNING
http://www.cobbtuning.com/ makes a device for Mazda, Mitsubishi, Subaru, Nissan and Infinitys. However they don't seem to make any products for European cars.
Also does anyone have recommendation for a GPS lap timer device?
