nice plot ron. im assuming this is your car?
getting the A/F curve is not the hard part tho, theres A LOT more to it , especially with a full standalone, but then again thats why sfp and frank are one of the best

just out of curiousity why was he stepping into so late? an sc61, no matter what trims are in it, will definitely spool earlier than 6500. and also i would have leaned out the mixture a bit(12.0-12.3)but it all depends on what u were trying to do with the tune and the owners preference if he has any. any idea where the timing was under full load?
but all and all like i said earlier nice numbers.
