I am curious how to fine tune the fuel delivery and A/F ratio with the FMU being used in the vortech supercharger kit. Some people have mentioned changing discs to control fuel flow but this sounds pretty crude. What to do???

 

There are two ways you can do this. You can change the disc inside of the FMU, but I would only do that if I changed out injectors size. Or you can purchase on of those air bleeder regulators for $25.00 that will hook up directly to the FMU and you can further adjust it the FMU to a full ratio setting.

 

Isn't there something you can connect to a laptop and modify programmatically? My installers have mentioned something like this.

What disc size does the Vortech unit come with in the kit?? I am assuming probably a 10:1 . I am at 2200 ft elevation so I wonder if going to an 8:1 disc in the FMU might be a better choice to keep from getting overly rich? Opinions from Vortech guys??

 

Are you referring to a plastic aquarium valve to bleed off boost pressure like we used to use on Honda's to trick to MAP sensor out of seeing boost??
