1422D probably, but would be better to disassemble the file.

Can someone help me to get CC work on ME 7.1 file
8D0907551G is well defined, but I can't find CWFGRGA. I cant find it in any 2.7T file, only in R filr but that is M7.1.1.

My problem is after fitting 6HP gearbox I don't have CC in 6th gear

I can't fool ECU with NVQUOT beacuse it get gear position from CAN-BUS(gearbox)

CWFGRGA don't exist in 8d0907551G.
This ME7.1 file use constants
GAFGRO  - 10C75    [Max. zul. Gang bei FGR-Betrieb]
GAFGRU  - 10C76    [Min. zul. Gang bei FGR-Betrieb]

BTW 6-th gear is valid in original fimware.
Your problem is that this firmware can't be coded to use AT tranny.
There is only two valid coding 10611 and 10711.
I think it will be easier to cross-flash firmware to 4B0907551S_0001 factory made for 5HP and adapt it to 6HP.

To be precise I use 4Z7907551D software that can work with AT trans , it is really similar to 8d0907551G software only that G is MT
Tomorow I go to trip, you save me 500 miles holding foot on throttle

Hi all, my friend have a 2011 Caddy Ecofuel with 2.0 BSX CNG engine. Its stock 5spd gearbox had been swapped to 6spd GQN gearbox from 1.9tdi. So gear indicator on the dashboard is off and cruise control doesnt work.

I have found damos for old sw version, found NVQUOT maps and make two files: first with simple 4 and 5 gears mod for values of 5 and 6 from original EDC16, second file with addition 6 spd instead of zero.

But nothing: the gear indicator only flashing for a couple second and off. With second file 6th gear indicator began to appear. Cruise doesnt work.

We simple measured the gear ratios and they approximately coincide with the average values of the ranges from the EDC16.
So unfortunately I dont understand where is mistake. Can somebody advise please?

Caddy ecu is 06G906022S Me7.1.1, gearbox donor is 03g906021KC EDC16.
In the EDC there are reversed gear ratios named Gearbx_rVn from 1D4D2E address


Did you manage to get the CC working in 6th gear? I have the same Me 7.1.1 with 06G906022S and I did the same gearbox swap. From 5 to 6 and no CC. Do you still have the flash ? Or somebody can modify my flash please? I can't find anybody in my country to modify it. I attached my flash .
