Code P0234 (Overboost Error)
Code P0234 (Overboost Error)
I just recently got my Flashpro for my 2019 civic si. Car is stock.
Flashed it with the +6 tune.
Every time Id do a pull the car goes into limp mode and the check engine light, VSA, EPS, brake hold, and some others would come on.
Im running the Hondata Mobile on my nav, and the code P0234 (overboosting problem) would show on it.
Ive tried reflashing the car multiple times already and that would fix the lights but I just run back to the same problem over again.
Anyone else having this issue or can help?

Re: Code P0234 (Overboost Error)
Post your calibration and a datalog using that calibration that shows when this occurs.

Sorry for the late reply.

Re: Code P0234 (Overboost Error)
Why do you have the secondary O2 sensor disabled?
Re: Code P0234 (Overboost Error)
Oh I must have accidentally disabled it while I was going through the calibration section.
Anything I can do to prevent this error from occurring?

Do you have any throttle pedal modifiers installed?
Re: Code P0234 (Overboost Error)
No I don’t have anything installed except for the FP
Re: Code P0234 (Overboost Error)
If you return to stock, form the online menu, do you still get the error?
Re: Code P0234 (Overboost Error)
Post the calibration used and a current datalog showing the issue made with that calibration.

I have the same issue happening. We’re you able to fix it?

That is from almost a year ago was not using the current software.
