I have a Zex Dry Kit and VAFC. I set the Lo/Hi throttle point to 10% 95% instead of the default 10% 50% and only adjusted the narrow throttle settings leaner (about -6% correction across the board) , leaving WOT (Zex TPS Activation) occuring at 100% throttle +- 5%. I have an A/F Gauge (Yeah I know you should not tune with Narrow Band O2 Sensor!) But anyhow the readings seem to consistantly stay at the leaner end of stoich until 95% throttle and richen slightly during spray activation with vafc not manipulating MAP pressure during the Zex Spray which also causes the exact bottle pressure to go the FPR letting it controll raising the fuel Pressure.
Anyone else try this or have any comments?
