Hello fellas. Today I tried E30 map on my 135i. Put 4 gallons of e85 and the rest 93, maybe short one gallon of being fuel tank. Should be around e31%.
I drove it around for a bit and then did a 3rd gear log. Hard to get traction this time of the year, so I think tires slipped a bit causing some issues. Traction control was off but stability control on.
The things that worry me are cyl4 timing corrections and especially the HPFP actual pressure being completely off. The LPFP is falling off quite a bit as well. The boost is sporatic as well and spikes quite a bit (see the graph to the right of the log).
Does this mean the HPFP is going south? I think it was replaced last year according to previous owner.
Here is the log:
