How to change ECU for EFI timing

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.

Re: How to change ECU for EFI timing

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.
