Dennis,
I guess the idea is to be able to change the commanded a/f ratio if the boost (or airflow) is lower for a given rpm. For example, maybe the a/f can be leaner if the boost is 3psi at 3600rpm, than it is at 12psi at 3600rpm. I'm not sure whether there is anything to gain at this point, but it seems at least a little more useful than the original PE vs. TPS table.
Carl,
I agree that a +/-200% PE vs RPM table would be more helpful. I've found the same thing with big injector calibrations, PE vs. RPM can't add enough, so I end up with 50-70% in the PE vs TPS table (at least with the race chips). At least maybe we could get it all on one table.
All great info!
Eric
