Honda Accord 2.0t 10th Gen issues after Flashpro

[echrispot@gmail.com]

Hi there,

I used the Hondata flashpro approximately 10 days ago on my Accord with the stage 2 tune. Everything went great and the tune was active. Fast forward to 3 days ago and I begin to get a barrage of error messages and check engine warnings while driving but the vehicle continued to run well.

I decided to reflashed the car to stock last night to see if it would make a difference as I have service booked on Monday anyways. Last night I am driving to the gym and the car starts stuttering and I was unable to get past 60 km/hr, no boost and having issues going up hills. I stop the car for a while and it begins running fine but with the warning lights still present.

Now today I begin to play around with the Flashpro and manager again because I am becoming concerned and now when I try to use the push button start on the vehicle, I am unable to turn on the engine. So now I cant even bring the car in for service this Monday without a tow and my car is sitting in my parking spot.

Please help! I am a car modification noobie and I am worried I may be in over my head. The battery light is essentially the only light on my dash not flashing right now so I don't think I need a boost.

Thanks! If anybody is able to reach out over discord to help troubleshoot I would be willing to pay. I really need my vehicle up and running.

So it is doing this on the stock calibration?

Have you checked for error codes?

Hi! Yes I went through the return ECU to stock process. I went through the OBDII diagnostics as well and it was showing every error code. Since the engine wont start now I cant really do anything because the ECU cant connect to the flashpro correct?

Since it is returned to stock you should have this looked at by a Honda dealer to see what has happened in your vehicle. If they have to replace the ECU make sure you unlock the FlashPro before doing this.

have you checked the fuel pump recall?
