I installed the flex fuel kit and flashed the hondata tune for 2.0 touring. Car seams to drive fine but has lots of errors for lane keep assist, collision mitigation, tpms, can't change to sport or eco and many other errors. I returned the tune to stock and all errors went away and it drove fine. What did I do wrong? Car is a 2019 2.0 touring automatic.

Have you tried reloading the updated tune file?

Not yet. It was late last night and I had work this morning. So I figured I would try again today and see if there was anything I missed.

UPDATE:

I reloaded the tune and it works great. Put in half a tank of e85 got 37% ethanol total mix.

I installed PRL Flex Fuel Kit in my 2.0T Touring and later, with low fuel warning, filled with E85. KTuner ECU tuned for flex fuel and E85. E55 mixture. Running great. Will fill several more times with E85 and tune again. Great acceleration!

I have a 2.0 accord running on the base map for ktuner. Thinking to add in the prl flex fuel but would I need a custom e85 tune for ktuner? If so would anyone be willing to give me a copy of theirs so I can also use the tune.

Yes you will need a tune otherwise the car won't know what to do and you will have miss fires and other issues. I used the hondata and the e85 tune was free to download.

Nice. I have a ktuner but I don’t think it has free e85 tunes for it or on my v1.2 as far as I can tell. Anyone with a ktuner have a tune for me.

I recommend waiting to do this until your fuel pump has been replaced by the recall. I have to get back to an e10 mix and back to stock before they swap the fuel pump.

There is another thread on this further down on this forum. A few people reported no open recalls but either got an email or call from the dealer. I got a letter. Supposedly around 1k 2018-2019 accords, but it also seams to be expanding. I will wait a little while for the dealer to get slightly better at it before the mess with my car.
