fastest way i know of is to adjust the global injector vs kpa table. Increase the given size of the injector there and the ecu will think the injectors are bigger- thus scaling down fuel globally in that region.

someone should ask why your fuel trims are so rich, what did you do to get that way- but I am not addressing that. I am only answering your question directly in the simplest quickest manner.

Where are fuel trims -25? At idle? Cruising? I assume LTFTs?

Have you cleared your trims after tuning? You should always clear your trims when you go to log fueling.

Also, are you logging your VE table or MAF table?

If you're rich in a certain area, you need to lean out that area. No need to change the injector vs kpa table. Quickest and right aren't the same thing.

Just search for how to tune VE. Do not try to do the injector scaling just like the old Diablo Sport handheld. It screws up so many areas in the tune. If You need to ask more, We're here.
