XDI FUEL PUMP and 1400 cc injectors hondata settings

[govols187]

First, Merry Christmas to everyone. I have a FBO 2019 fk8. I've recently installed the RV6 turbo about 2 weeks ago. Everything was fine. Yesterday I installed the xdi fuel pump and 1400cc injectors. It runs fine except the short term fuel trims are +10-+15. The long term is cutting fuel. Does anyone know any settings I need to change in hondata to fix that? The instructions that came with it said to change overall fuel trim to -19.5% but it ran poorly when i did that. The plan is to drive it to the tuner about 45 minutes away. If not I'll have it towed.

When people buy my tuning services I provide a base calibration or can be custom tuned remotely or e tuning by email , no need to drive at tuner location .

Long term is subtracting fuel while the short term is adding? Sounds like your long term hasn’t updated itself and needs more time. Drive it a little more and see what it does. Stay out of boost as best as you can. The trims can go from -20 to +20 so you should be okay for now

I did end up changing a couple of settings but you're right it did get better with time.
