Fuel Injector Scaling and IDC

Hi guys Does fuel Injector scaling have any effect on Injector Duty cycle ?

I noticed my ID 1300 CC is nearing 95 percent already on e85 i am trying to diagnose if its because fuel pump needs upgrade or if i set my fuel injector scaling too low or high.

No, IDC is what it is so if you're at 95% IDC then that is what the ECU id commanding of the injector. Scaling effects what pulse width (and hence IDC) the ECU will command to achieve a target AFR.

I use the fuel trims as a guide to how well dialled in my injector scaling is. I'd be checking the fuel pressure to see if the pump is struggling to keep up.
