Hondata

Disregard original post, issue is resolved.

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.

Update: I reinstalled the USB driver and now it's working... I think... I'll get back to you.

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 ...

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.

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.

Although I'm sure Hondata will give 10th Gen Accords some love in the future, for right now I need a little help and I'm hoping one of you either has something already, or can work some tuner magic.

What Hondata system: FlashPro
What vehicle: 2019 Accord Sport 2.0T 10AT

Is your ethanol content of 32% accurate based on what you have put in the vehicle?

You're running large negative fuel trims - up to -25%.

Go back to E10. Disable ethanol. Check fuel trims and if necessary adjust the AFM to get them correct.

Then enable ethanol.


Forgive me but I have no idea ...

Yes, 32% is about right.

Those fuel trims are what is in the base "flex" calibration.

Also, something I noticed is the throttle plate is very erratic sometimes. Not sure if this has anything to do with my problem.

Let me add a third person on here with the same problem...

I've had that problem for literal years now but found that holding the rpm a little higher keeps it from hesitating. I guess I've gotten so used to doing that I forgot it's actually a problem. The next time I use the cruise control I'll ...

Spunkster is 100% right. Honda dealer took care of this for me and it had absolutely no effect on my tune as the BCM is a component that's completely separate from the ECU. Don't recommend leaving your FlashPro plugged in when you take it to Honda though.

rainy187, I too want more for the accord. Post your idea for a change here: viewtopic.php?t=17390

Looks like the 3D tables do not have the same values as the 2d ones in the base calibration. More accurately, the 3D tables have the value of "3.000" in every space for the Ethanol advanced boost limit, and "0.000" in every space for the Ethanol advanced fuel multiplier.

Why not use the advanced ...
