Your information is terrific. Perhaps you have, or know of a system that is already on the market that works with the Crossfire. Read, Write, Modify ?
Yeah, after watching the California police training video I figured you must be off-road-only.
Of the tools I know of (which are only available to chip tuners) the costs are right up there with the MOTEC if not more and they typically still don't tell you where the maps are or how to scale the parameters.
In your case I'd try to collect some data and figure out where the car isn't running right and see if there is anything you can do to make it run better.
(ie fuel trims not working, knock causing enrichment, temps too high on the track, MAF out of mapped range, etc. etc.) Perhaps Powerchip can do a re-map based on your setup?
Otherwise for a lower-cost approach maybe look in to a piggyback like the SMT-6 from
http://www.perfectpower.com or see if one of the air-fuel-timing calibrators from Split-second might do the trick

These work by altering MAF and crank signals although you have to stay within the limits of the stock ECU mapping. Your mods are not that extreme relatively speaking so it might work for you.
