Adjusting fuel consumption display for injectors

[gtimart]

I just realized that the fuel consumption that my trip computer displays is wrong. I know, it took me a few months to discover that, I just wanted to believe my car was a good performer
I have a GIAC FXK03 with 380cc injectors, so I understand why it's off. I have read on these forums that there is a way to set a compensation factor using VAG-COM. Have any of you done that and if so, what factor have you all been using ?
For the trip I did today, I seem to have been using 25% more fuel than what the display says, but I know measuring when filling up the car is not very accurate. Therefore, I'd say I think I probably need a value around 15-20% more but I'd like to hear other people's opinions.

Post #13 and 15: Clicky click Use a factor of 115% (max). You cannot correct it completely. The FX program will be off closer to 130%.

130% even for ko4?

i adjusted mine to 115% and its fairly close when i do the math..

I thought with 630s we can still adjust the computer? Although it is pretty cool to see 60mpg

Oh no old guy, don't leave us. Do you need moneey to keep your A4? Maybe we can raise some funds

Would the APR 1+ with TT injectors also be at 115% or a little less?
