Hi,

I have a ford ranger 2000 and want to change the duty cycle of my injectors. How am supposed to do that ? Do I need to reprogram my ECU ?
If yes, how ? I really appreciate if someone can help !

Thanks

Yes, you can either send in your ECU do be reflashed, get a chip custom burned, or use some sort of custom engine management software that piggybacks onto your ECU.

You could also use some sort of generic piggyback like an Apexi SAFC.

I am thinking of controlling the fuel-air ratio and was thinking to do that by controlling the injector duty cycle ! is there a simplest way of doing this?

with an Apexi SAFC I believe you can do that directly, and it's a generic part. You'll need the pin-out diagram for your ECU to install it though.
