Ok I have read and read and read and Im just stomped. Had a friend who was going to tune it but it just sat for 4 months so here I am back at square one. I need help with tuning this thing. My wideband reads at 14.x when i start it but as it warms up it just stays at 10.0 no matter what I change unless just hit the gas pedal. Then it fluctuates and goes back to 10.0. Im in desperate need of a base map, a lesson, something. I'm tuning on hondata s300. T3/T4 turbo, 1.2 turbo regrind cam, 650cc injector, F22a6, H23 IM. Can anyone help? I at least want to get it Idling fine, which its not bad where it is, and drive it NA. Just some kind of progress before boost.

Hondata has an excellent help file that tells you the basics of tuning their software. Hondata also has an online forum.

Well, a bit of Google shows you a lot of results of forum threads, like this one:https://honda-tech.com/honda-prelude...e-map-2218853/

If you are not sure about you are doing with tuning, leave the job to a tuner. A bad tune would broke your engine

It's most likely an injector battery offset, if it's a tuning issue.
I would also check for physical malfunctions, like an injector stuck open, bad wiring, bad main relay, bad ecu or S300. Or perhaps a malfunctioning wideband.
...you are using a wideband right?
You can read the tuning manual in my signature. it's for crome, but since they're both rom editors, it's the same thing. Just a different layout.
