Yes and no.

Mr. Big bucks would be gutting the factory box completely and having a one off custom engine management system manufactured that would allow full control, fit within the factory box, integrate with the factory wiring harness, and even utilize the factory sensors.

That's my point, Jeff. My letter requested a reversion back to OEM computers but allowed any modification to the software. So Mr. BB can't just "gut the factory box completely", lest he falls afoul of the rules. The limiting factor in my case would be the computer itself. As it is right now, the limiting factor is simply the size of the OEM case and the racer's wallet.
