Hi,
I noticed that dfco in my 00 C5 is just working when decelleration in 4th gear. I have tcc lockup in 3rd and 4th.
I get 99mpg inst. only until it shifts down to 3rd.
My dfco settings are pretty agressive arleady but still I would like it to be active until my minimum set speed of 24mph.

Are there any settings to be made to let it stay on in 3rd and 2nd gear?

Thanks
Alex
