Yes you can still change the selection, but whatever it lists automatically when you have it plugged in and click New Calibration are compatible with your vehicle.

All stock sir. No after market parts. Going to try and reflash after work. Also had a CEL flash while driving to work this morning on a 6+ base map had to pull over and turn off the car and on restart it again. I've watched @phong.vlg video for reference. If I'm doing anything wrong let me know, thank you.

It seems like when I put it in third gear it has a hard time accelerating, when I push on the gas

You should try returning the ECU to stock and see if the problem persists. If it does there may be a problem with the vehicle that you will need to have Honda look at.

I’ve been having these issues since I converted to flashpro on my ‘17 si. The misfire codes you posted I got after I changed over to the fx400 clutch kit. Turned off misfire detection and that went away. Lately the issue got worse. I have miss’ under accelerated positive boost while the engine is near 135*. Once the car warms up it goes away. So I’ve switched over to use MAP to determine WOT and a lot of adjusting on the lean tq table and wot table. Check your fuel injectors on a data log to see if your hitting 9ms or over 40% duty cycle when it happens
