Thread: Does Learn meet your Target AFR?

  1. #1

    Default Does Learn meet your Target AFR?

    I assume I set the Target AFR on that table and the computer (Dominator) will try to reach my set value by making whatever changes it needs to? Right now my actual ratio is running at 20:1 at idle and I have the table set to 14.1:1. Do I just have to keep driving the car so the computer can Learn? Thanks in Advanced

    If the actual AFR at idle is 20:1, it would not be running, I promise. Something else is going on. There's a lot more to the overly simplistic description that you posted. Yes, that's how it works, but other factors can come into play, such as you Learn Limits, and any other conditions that might be present in the Learn Parameters. More information about your car, engine, etc., would be helpful.

    If I can be of service with the tuning process, please don't hesitate to get in touch. Andrew

    @andrewb70: Thank you Andrew. I had it professionally tuned and it was running perfect. But long story short, had to wipe the computer and start from scratch and have no idea really what I'm doing.
