very high idle.

[kpthemanatee]

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?

[Spunkster]

What vehicle are you referring to?

[kpthemanatee]

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.

[kpthemanatee]

Ok done
It did throw a code too.

P0507

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

[kpthemanatee]

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.

[Spunkster]

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

[kpthemanatee]

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?

[Spunkster]

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

[kpthemanatee]

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.

[kpthemanatee]

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

[kpthemanatee]

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

[Spunkster]

Yes it should be ok now.
