Block 031 Graphs

Installed 310cc injectors and 3 bar FPR this weekend (thanks to Greg and Ed) on my K04ed 1.8T. Seemed to help my lean condition, but the car is now pulling fuel. Block 032 reads -4% @ idle, -10% @ part load.

Here is a graph of 031 from about 6PM last night.

Then about three hours later

Sorry no RPMs on the 2nd one, wanted a greater sample rate. Both were WOT pulls in 3rd though.

Seems like A/F ratio is alright, but will the car keep pulling fuel until it is too lean again?

-4 and -10 are where you want them.

Your graph #'s also look good since they stay above .82, a few others also said that chip ran a little rich in the mid range which you can see on your graph.
