Update:
I've sourced my problem...
The plugs are actually fouling, because I have magical disappearing coolant...
I'll see myself out...

Re: FlashProManager 4.7.7
Only does it when comparing an old calibration to one you just made.
I played around with it and I'm confident you can recreate it. Not sure if it happens for all new calibrations, or just mine so here are the exact settings for the one I was using.

Re: FlashProManager 4.7.7
I just updated to 4.7.7.0, and it appears that the compare calibration function is still not working right. In the image, the identical values shown are from two identical calibrations, but it still says there are differences in Injector phase (WOT). This is the same behavior I saw in versions prior ...

Re: Misfire, hesitation, lurching, something? Please help.
Update:
Car would NOT start a couple of days ago. Replaced the spark plugs (again) and it fired right up. However, it still has the "misfire." Plugs I removed were OEM purchased from Honda (NGK 92411 DILKAR8P8SY). The plugs were only two months old, and based on the heavy deposits, it looks like ...

Re: Misfire, hesitation, lurching, something? Please help.
I forgot to add to the last post that I'm also having a hard time starting the engine now. It really struggles and seems to only fire on a couple of cylinders for a few seconds then the others start to fire with all four eventually working.

Re: Misfire, hesitation, lurching, something? Please help.
Ok so I've replaced several parts, but I'm still getting what I'm calling a misfire, though it may have a more appropriate name. This is the same issue that my original, and all subsequent posts are about.
I've replaced:
Low pressure fuel pump (w/ Hondata pump)
Fuel Injectors (OEM - Honda ...

Re: Misfire, hesitation, lurching, something? Please help.
Thank you! Alright, I just ordered a full set of ignition coils (Hitachi). Should be here in a day or two. I can tell you that it was 100% NOT my fuel injectors as recommended by my local Honda dealership... Just shelled out $1,500 for that today and it literally changed nothing so now I have a ...

Re: Misfire, hesitation, lurching, something? Please help.
Car still hasn't blown up, but still having the same problems. Can someone please take a stab at recommending something other than what Hondata told me because their advice was absolutely no help.

Connected my FlashPro to the computer today fully expecting for the firmware to update as I haven't connected it in a few months. I made sure before starting that I had the latest version of FlashPro Manager. When I connected the USB cable, it said it would update the FlashPro firmware, but then ...

Re: Error code, hesitation on idle, fan runs constantly, high idle on start
A little late, but thank you for the answer. That fixed the issue as I'm sure you already know since the base flex calibration now has that disabled.

Re: FlashPro Manager 21 Accord 2.0T 10AT
Follow up question:
Do you ever intend to create mods for the 10th Gen Accords?
I would literally pay for mods and updated calibrations at this point. If you charged a subscription fee for access, I would pay.
