I've worked with NASCAR as part of a manufacturer's support group and with 4 of the GM teams. There is a clause in the NASCAR license that you agree to inorder to get credentials for entering a track that prohibits criticism, derogatory language, unsafe practices and using unapproved equipment.
Brad was upset to learn that the fuel injection equipment he was running, on that day, to participate in a fuel injection test session was not port or direct injection, but was throttle body injection. That system uses a single or pair of injectors to feed both or individual banks of cylinders. He was expecting a system with 8 injectors programmed specifically for each bank.
You can just imagine the monkey shines that a race motor engineer could dream up in order to gain an advantage (buy power, save fuel, save heat (loss of coolant), limit rpm, balance torque, adapt to cam twist, inop cylinder, adaptive compression (aging during the race), knock sensor, post race power audit, dry ice in the airbox, etc.) once some wires and a controller and a computer are hooked up to the fuel supply. Yes, NASCAR would issue the boxes, but what things the box talks too and what things listen can be a creative genius's best work.
NASCAR does not allow real time or remote control modes in engine or chassis systems management like INDYCAR or Formula1 does. In those leagues, the ones with the most money usually win. NASCAR likes 'creativity'. I loved working with them. For example: steel coated titanium parts: All parts of the chassis must be magnetic steel, tested with a magnet (per the rulebook). And the magnet sticks, just not to titanium....
