ColorMFA

I've got a problem with my Golf mk4, when i'm driving along the gear assist works great, no issues what so ever.
But as soon as i let of the gas to "engine brake" it hops to N. When i press the gass again comes back to normal.
I've just instaled ColorMFA in an S4 B6 aswell and in that car its working perfectly.
My car is quite heavily tuned on the stock ECU(ME7.5), so i'm not sure if the gear assist uses caluclauted engine torque or something. I just updated to the latest firmware of ColorMFA but still having an issue.

What is the current consumption displayed when driving in "engine brake" mode?
Can you take video of CAN-monitor (only with an active "Motor CAN") while you driving with "engine brake" ?

Here are the pictures, the car has "overrun/pops and bangs" enabled. That's why the fuel indicator dosent go to 0.

Nothing is visible in the photo with such poor quality.
But it doesn't matter ... There is no fix in ColorMFA because you have changed all the markers used to identify neutral gear. If consumption is not zero motor load is also not correct and torque is not correct... It can only be fixed in the firmware of your motor.

That's what I thought, thanks

Autopilot could you short explain identification of neutral gear in latest fw ?
I found: if i put gearbox in neutral when car is in moving ColorMFA shows fifth gear (have no sixth) and shift down red arrow.
This is pretty logical for me - RPM on idle (800) is under minimum value i set (1100) and the ratio between speed and RPM is highest on highest availabe gear - fifth in my case.
Did you implement additional neutral gear detection (for example: 0 throtle pedal position, engine torque arround zero, RPM about idle combined with speed higher that corresponds to idle RPM ...) ?

Yes, additional detection implemented. Throttle, consumption, rpm... but this does not work on all vehicles now. Need to check cars where it not work, may be not all function is present on CAN and need use other "markers".

Good day
I have the same problem with my Passat 3BG 2.8L. It always shows N in "push mode". Engine control unit is 3B0907551CH. Could they fix this as well?

What is the current consumption displayed when driving in "engine brake" mode ?
What firmware are you using ?

Firmeware is the _b5_flash_v2.9.4b36. What is meant by this "What is the current consumption displayed when driving in "engine brake" mode"
The fuel consumption is there at 0.

It always shows N in "push mode".

"Push mode" is a same as "engine brake" mode ? Right ? Or am I misunderstanding ?
In this mode, the fuel consumption is 0 ?

Yes is the same.

See PM

Hi,

I have a 2005 Audi TT 8N and I also am having issues with the gear showing - if I lightly push the clutch in it does show the gear. How is it calculated? I have changed the clutch switch and it is still not working

the gear showing -

Showing - ? ColorMFA does not display -. Only 1-9,PRNDSL

Sorry gear is showing N, unless I press the clutch in a small amount

If you fully depress the clutch pedal, N is displayed ?
I do not know, but I think is a mechanical problem. It may be necessary to adjust the pedal position sensor.

When I'm coming of the throttle ColorMFA shortly shows N then goes back to the correct gear. This is because ME7.5 ECU atleast has overrun for 1sec where the consumption Is not 0. Can this be fixed with a newer firmware? Also when catalyst heating is active N always shows when engine braking. Cannot ColorMFA use clutch switch to know when to show N?

Yes, I know about it. I'll try to fix it in the new firmware.

ColorMFA use clutch for displaying N. Every pressing cluch ColorMFA must show N.

Maybe adding a condition that RPM must be lower then 1000 (when car is moving) to show N will be solution for unwanted N showing.
