I may not have the correct terms,this will be in KY hillbilly terms.
I had a customer a few years ago that was doing what the article talks about by accident.
He had mustang sbf turbo running 8.5X26 outlaw class, they ran a low 5.20 and was going down track like was on a string,they tried to step it cranked around 4-5 lbs. more boost in should have blowed tires off or flew,still went low 5.20 like it was on string,took them a while to figure out,that they couldn't go any faster than a low 5.20 until they changed the timing curves in box,everytime car went to spin or rpm went above certain rpm at certain time/point it would yank timing out to keep it within the settings of their baseline low 5.20 pass.
Made changes in ignition box then they could blow tires off and go faster,went 5.0's almost instantly eventually went 4.90 something.
A guy in shop yesterday said dirt track guys run two boxes,when track gets black slick during race they switch boxes.
I'm not sure,I guess you have to hook laptop up to make changes,would be why they use two boxes?
