I have a pc5 on my gen 3 drag bike. Recently I did some dyno work and got the AFR where I wanted it, the PC5 worked great establishing a NA map. Once happy with that I started spraying a 20 hp shot of nitrous at it. It went lean at first, as expected since I didn't make any changes to the map. I then added upwards of 35% fuel in the 80-100% TPS cells from 7000-13000 rpm and it literally made no difference to the AFR. I double checked the adjusted map was sent to the PC5 as well as double checking I had the map switch in the proper position to run map 2. After all this, there were still no changes to AFR.
At this point we stopped before the motor got hurt.
My question is: does anybody know what % fueling the primary and secondary injectors perform at wide open throttle? Aside from going back to the dyno to make another pull and see the duty cycle of primary injectors, I can only assume the primaries are maxed out and can spray no more. I do not have a SFM on my bike, yet, so as of now I no control over secondary injectors.
thanks in adavance.
