Hondata

just reflashed my tune after software update and battery change and now im getting super high idle... can drive the car. i turn it on and it revs to like 3-4k on its own and keeps wanting to climb so i shut it off. what could it be?

What vehicle are you referring to?

Sorry about that. It's a 2019 honda accord sport 2.0 manual

With everything plugged in and the ignition in the on position, go to the Help menu and click on “send feedback”. Include a detailed description of the issue.

Ok done
It did throw a code too.

P0507

If you go to the online menu and return to stock, does the problem persist?

Yea so I had it on the flex fuel flash and I flashed the base calibration and it still happens.. I'm going to reset the throttle position sensor Sunday to see if that does it.

Did you go the online menu and return to stock, or did you use a stock equivalent calibration?

Base calibration. I need to take it back to stock and try that bc it's still doing it after a oem scanner tool trying to reset/relearn throttle position sensor didn't work. I took it to Honda and they want me to get a whole new ecu.. Any thoughts?

Do not replace the ECU. Please go to the online menu and return to stock and see if that resolves the issue.

Ok
I'll do it tomorrow and let you know what happens. Thank u.

Please download the most recent version of software at: https://www.hondata.com/software

This should fix the issue.

Ok. I got that email from your support staff. I'm literally flashing back to stock now. Standby.

😲 It worked! Is it safe to flash my flex fuel tune back on?

Yes it should be ok now.
