"Sorta. Government is the reason we have OBD2 in our cars, so a case could be made it's the government's fault we can't remove our cats, not the ECU. The actual processor in Honda's latest batch of ECU's have been the same since 1992. Oh, and OBD2 isn't engine management, it's emissions systems monitoring. The management system is all Honda."
I was refering to the technical aspect of removing the cat, not the legal ($10,000 fine if you're really unlucky) aspect.
Emissions control and engine management are one and the same. Yes OBD2 is emission monitoring at it's most basic level but it also includes emission strategy, new mil requirements, catalyst protection and generic data stream capability.
The generic data idea was really only for the emissions inspection programs. It is pretty much useless conpared to the OEM pids and bi-directional controls, I use it only as a last resort.

By the way, Spoon has an even thinner head gasket that raises compression to 12.2. Don't know what the HP claimed gain is.

whats the "piston to valve" and "piston to head clearance" like? Do you think we could change to the thin headgasket without interferance problems. Just detonation problems.
Is there enough room for a big cam without modifying the pistons first?

Some GM OBD2 vehicals maintain fuel control even at wot. They use o2 data at wot. On the dyno, you can see with a labscope that the o2 sensor waveform is moving but is biased rich.
