MED9.1 Speed limit 32km/h

[MarkusUPP]

Hello! Could anyone help me with a speed limit on a Audi A4?

Audi A4 2007
2.0 TFSI 200hp (BWE)
Quattro
Automat

MED9.1

Its a "Swedish EPA tractor" thats a 15years old can drive, and they are only allowed to do ~32km/h
And if I remove ABS fuse, Car need to still do max 32km/h.

So maybe limit rev on each gear? so then its work even if car dont have speed signal.

So can anyone get this working good with a nice, soft cut wich is not felt. and working good with automatic, so car never can go faster.

Flash + eeprom read with flex on bench

Thanx!

Hello, try to set this two Adresses (1DDD5E,1DDD60) from 32640 to 4480 this is Maximal zulässige Fahrzeuggeschwindigkeit

if you want to change rev Limit you can try to set this Adresses (1CA7B6) from 6800 U/min to a new test value maybe 3500

But i think to limit it only by rev its not the best solution.

please try and report !

Hm... as i know gear detection is based on correlation between engine and vehicle speeds.
So, my opinion is, that without speed signal is not possible to do speed limitation.

[morgano]

Just an idea...

What about setting vmax to 32

And locating abs dtc when fuse disconnected and modify that dtc behaviour not to allow car start?

[MarkusUPP]

Vmax I have solved to ~32km/h

But now problem is abs.

Car inspection test remove fuse and wheel sensor to se that car still only do 30km/h

Any way to do a limp mode function that limit engine rev/dont work at all if its any fault in abs system?

[bobolin4o]

Test this file and report...
No checksum, FLEX should do it.
Regards!


BTW... these GAYS at car inspection test must know, that is not possible to limit the speed without speed signal!

[MarkusUPP]

Only speed limit?
That Have I already solved

Don't lough... test the file with abs off.

[MarkusUPP]

I dont lough, I just asked

I test it, 10min (Y)

Speed limit work, but car go normally (full speed) when abs fuse is out

Test again, the PW is same...

Should have 1500rpm all the time, without fuse...

[MarkusUPP]

Yes it was limit on 1500rpm. But even with abs fuse in xD
So its not working when car is "normaly"
