Hondata

Hi,

I recently purchase a Flashpro for my civic 2016 turbo.

I flash the computer and then a got a check engine. I looked for the code and I saw U0301 and I'm unable to erase it. I looked on the internet and I see it is a mismatch computer.

I try to flashback to stock ECU and it still showing that error code.

My ECU number is 37820-5AA-C66

I bought my car in Canada

Please help me.

Thank you,

Samuel

The error is because the ECU probably has been flashed by the Honda dealer to 2017 to match the TCM.

What calibration did you load? The 2016?

Hi,

You are right. Honda had to flash my computer one day because the car rpm varies on the highway.
I first flash with the +6 psi first. Now I back to stock ECU. So you think flashing with 2017 will solve my problem. If so, how can i do it? And if I want to go back to stock ECU, how do I do that?

Thanks,

I tried to use a 2017 Canada Touring one and it didn't want to flash. I tried many other, same thing.

I flashed on a 2016 one.

How can I flashed with a 2017 one?

Can you use the 'support support information to Hondata' function from the help menu (with the FlashPro plugged in)?

Hello,

I did a firmware update and I was abble to flash on +6 psi 2017. All the error code is gone.

Thank you so much.

Ok, glad it is sorted out.

hello, i am also having this same problem. but with the recent update of hondata. its says i cant up load the 2017 or 2018 cvt tune to a 2016. please advise

to add, i was able to do this before on 3.5 i think, but once it updateed to 3.7 it no longer let me upload the 2017 tune

Our crystal ball is broken - please some details.

nevermind, went for a drive after uploading the base map and check engine light went away.
