Custom maps, sure things have advanced since the making of this video. I would recommend coughing up the money for a stand alone. If you’re strictly racing the car an emtron kv16 with a pdm would highly benefit in what you’re trying to do. You could add sensors to your suspension, professional awesome has inexpensive tire temp sensors and if you a digital dash you could log you laps and go over the data to see where you can pick up time.
Just an idea instead of adding a bunch of other stand-alone devices to the car, just more things to monitor, more things to go wrong, and at the end of the day you spent just as much money as a stand-alone and pdm, plus there downtime figuring out how to get all this to work with the factory ecu.
