Can you post your calibration as well as a datalog showing the problem?

Hi everyone, I'm getting the same issue. I'm running the +6base map as well. I only use Shell 91. I tried getting back to stock to see if it was Hondata issue and...I got the misfire code as well.

What I notice is that is only when is cold and humid...I check spark plugs and coils and they are fine. Injection perhaps? How long of data acquisition do you need?

TL;DR, had faulty injectors and had them warrantied out.

Can you please attach your calibration and a Datalog to your post here?

Already did :-) datalog can be accessed by WeTransfer. File is too large to be attached here.

You can trim the Datalog down to make it much shorter and much smaller file by right clicking and selecting a start and end point then saving the Datalog with a new name. You must also include the calibration. Please post them here.

hope this help. I'm using calibration Hatch Manual, but my car is a Sport Manual. I don't know if this can affect anything...
