I just install a Walbro 255lph fuel pump in my car. All I have is an AEM intake and an exhaust with 2.2 inch piping from the cat. My fuel pump went bad so I decided to get a high flow instead of stock cuz I'm going turbo soon. NOw that I have the high flow pump, I believe I have to change my VAFC settings so that I don't flood the engine with too much gas....especially when VTEC kicks in. Any experiences with a situation like mines? What settings could I use to regulate my fuel now?

 

Go to the dyno....Thats really the only thing you can do. I mean im sure you can get settings somewhere but like its always said..."every motor has different needs" So even if we had the same setup there would be differences in our vafc settings...not every motor is alike.

Also, ive never heard of a vafc and walbro flooding the motor...you may run rich though. With my mods and vafc (i have a walbro too) ive never "flooded" my engine...just really really rich.
