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

You must code ECU to 6 gear also in VCDS

Do you change ECU coding from 5G to 6G ?

No, I dont coding anything. What coding are you advice to try, stock is 0030071? This engine doesnt have stock 6spd gearbox, most likely no coding will be accepted.
Anyway my first file should work without coding, because I only change 4 and 5 gear ratios to new 5 and 6 values.

Accepted coding for this ecu are
30071
30051
30031   
30011   
20071   
20051   
20031   
20011
I do not have a exact description of the coding values
But you can try to change something and see what's happen.

Thank you very much, please tell me how you found possible codings? From the flash file?

Unfortunately I have found coding description for this ecu, so its not possible for 6 spd coding.

Yes, the table is in flash.
See at addr $EFEE2

Yust extend the 5 gear so it covers rstio for 6 gear. I think that is only solution. Or crossflash/diffrent ECU that came with 6sp gearbox

Thanks!

BlackT Ok, thanks I will try another values for extending 5 gear

CWFGRGA
bit = gear
change .6 to 0 to enable cc on a 6th

bit 0 = REV
bit 1 = 1st gear
..
bit 6 = 6th gear

value 1 = disable CC; 0 = enable CC for gear ?

Do I have that correct?

How does one find CWFGRGA in a bin? My ASM looks like this:

I know it's referencing CWFGRGA, but I can't figure out what absolute address from that code above. Any help?

edit: I just looked at my 5spd tiptronic bin @ 0x14512 and a C1 looks reasonable. 1100 0001 <= Rev disabled, 1-5 enabled, 6-7 disabled.
5spd manual bin has C3 disabling 1st gear. I'll change that and see if I can get DSG 6th CC enabled.

Thanks

yes
0x14512 & 0x14513 depending on engine coding

to enable cc on a sixth you should also touch FRARAWG a bit

Ah, I did wonder about the adjacent byte being identical C1 C1. I'll be sure to modify both.
Reading up on FRARAWG now.

Thank you!

CC works in 6th now. Thank you!

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)

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

Log stfgrab_w
Check fr for details

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.

Thank you till sky that is what I looking for.
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
Thanks again

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 .


Can you help me please?

i need to make the same things

As you can see one year since I posted nobody replied :( I almost got used to drive without CC.
