changing injectors

[Larry]

I have 83# injectors.. running 66-68% duty cycle.. Id like to change to 72#.. What do I need to do in changing my program set up on my speedpro?? Thanks Larry

First, just change the injector flow rate setting in the Fuel Calculation Parameters screen. This should cover most of it. You may need to tweak your VE table a little bit, but this should be a very painless change. The speed/density calculation takes the injector size into account, so simply changing this value should land you pretty close to where you were.

The only other thing I can think of is that you also might want to re-adjust your starting settings, since this is in inj ms and not a calculated fuel-flow number.

(If you run a dry nitrous system then you'd want to re-adjust those #'s as well, since they are also in inj ms)
