I am running a FuelinjectionPro (uses the same software) with the stock injectors. What year is your car? If you have one small and one large injector you way want to run 4 squirts per cycle to compensate for the deferent injector sizes. The best thing to do would be to use to large injectors (green), this would give you over 2,000 CC a minuet. :wink: Here is the constants and enrichments page on my setup. Required fuel: 6.2 Inj opening time: 1.3ms Bat voltage correct: .2ms PWm current limit: 100 PWM time threshold: 25.5ms Speed density 4 injections per cycle Alternating Four stroke 4 Throttle body Injectors: 2 250KPA Even fire I remind you this is set for 4 injections per cycle, at two injections per cycle the “required fuel†would be 12.8ms If you pm me your email addy I will send you two files. My latest, supper smooth idle, good low end toque and fuel mileage. Two, a two injection per cycle that has good top end. :twisted: Tom Cat 8)
