What do you mean with "the fuel gauge falls always as same slow/fast down"? The fuel level vs distance figures look about right, so I'm sure I am missing something. 60 km to move, 100 km = 75%, 200 km = 50%, 300 km = 25%, 400 km empty. If that is not correct, what would you expect?

Ok,

so:

1. If i refuel my tank completely full, than the fuel gauge goes up to completely full!
2. After 40-50 km the fuel gauge are not be moved (the fuel gauge indicates still completely full)!
3. After 60-70 km the fuel gauge goes one line down (compared to completely full)!
4. After 100 km the fuel gauge is about two lines down and not 75% (compared to completely full) !


Correctly the fuel gauge to go down to 3/4 full tank, after 100 km.

Yes, after ~200 km the fuel tank is 50% fully, after ~300 km, the fuel tank is 25 % fully, after 400-430 km (depending on driving style), the fuel tank is empty, thants all correctly!

But why the fuel gauge falls into the first 100 kilometers down so slowly?
Is it possible to calibrate this issue?

And please answer my question, what causes to change the following setting (for example 750cc/min)?!:

It is no differences in behavior, no matter if i use 750cc, 850cc or 1000cc etc.!

Here is a screenshot after completely refuel and ride ~87 kilometers.
The fuel gauge moved/changed just 2 lines compared to a maximum full tank!

That's fairly standard behavior for a Honda. My fuel gauge does not move at all for the first 100 - 120 km.

Ok, thank you!

And for what is the "injector flow for fuel economy" option in Hondata Flashpro Manager?

"injector flow for dash" changes the value that the ECU sends to the dash. The dash does some black magic with the fuel level and fuel consumption values to determine what the fuel gauge should show.
"injector flow for fuel economy" changes the ECU internal calculation for fuel economy. I don't think you can see the result anywhere.

Hondata, i have a another question about the "Injector flow for dash":
If i put in (for exemple) "845" and click on "save", the value jumps to "844" and when I click again to save, the value jumps to "843" and so on...!

Now i have put in "846", but it is not possible to put in "844" or "843", I would like to do!

Is this a bug and can you fix this?

Thanks for feedback!

It is a rounding error and we have fixed it.

Hi

I have been using a race calibration FlashPro tune on my 2010 FN2 for over 2 years now. About 6 months ago I reflashed the ecu back to stock via flash pro. Recently, I decided to put the tune back, so I upgraded the Flash Pro Manager to the latest Beta version and started facing the same problem as Neoark along with this error on the Flash Pro Manager.

Please can you advised why is this happening only now. And what alternative do I have now?
Thanks & Regards

You can still use it, but you must realize that no new features are being added and we no longer support the race calibrations.

I have ID1700x injectors and I changed all the values according to this thread but I am seeing around 23L/100km on the dash.
The values I used for dash and fuel economy tables are 1587cc. The fuel gauge seems more realistic now instead of suddenly dropping down from almost half tank to zero and also the current L gauge seems to change according to the throttle angle.

What value should I put to make it more realistic? Thank you
