For dyno tuning, we used FAST’s XFI system with an XIM ignition controller. After tuning the Base VE table in closed loop with minimal correction, the progressive nitrous feature in the XFI was used to turn on the nitrous at 3,500 rpm and over 85 percent throttle and ramp it in over one second so we didn’t shock the engine with a hard hit. The XFI was allowed to use closed loop to make changes to the fuel curve that would keep our target A/F ratio in check. This is the ultimate solution for drawing out the power safely and can even hold multiple tunes for street and strip.
