Hi everybody,
first of all, I'm from Germany and my english might sound strange, so please apologize for this.
I have a strange behaviour after changing the gear wheels on a Chevrolet Camaro MJ2017 V8 European Model
The standard setup for the Gen6 for 5th gear is 0.74:1, for the 6th gear 0.50:1.
What i did - and have done for the Gen5 about 30 times without any problems - is, i took the ZR1 5th and 6th gear wheels and swaped them against the original ones.
Now the gearing is for the 5th gear 0.81:1 and for the 6th gear 0.67:1.
In addition we changed the gearing ratio in the ECU by entering the new ratio in the schema.
5th gear is working without any problems, but 6th gear is causing a power reduction and a short time engine emergency mode if i push the gas Pedal more than about 10%.
It further indicates too much slip @ the clutch - which makes no sense in 6th gear. (a picture with the German Fault Code in the display in the notes)

Direct Translation of the Picture:
Action required
Reduced power
Reduce clutch engagement
So the 6th gear is not really usable....
Do i have to change any additional tables / schemas where the gearing has to be adjusted?

Looking forward to your thoughts and recommendations!
