Hmm, HPFP looks okay to me because its holding stock 110bar very good. LPFP is not @ 106, you have to find the correct block. Should show numbers up to 6bar. Dont know whats going on. How good is the fuel in your country? How old are your Spark plugs? Correct ones? There is lots of retard and maf diagram looks shit. (should be related) Interested in other opinions on this as med9 is still new to me.  |

On a stock tune, the fueling isn't being pushed like it is on a maxed out Stage 2. Lots of folks have fueling issues at stage 2 levels, in which case they upgrade the HPFP. Octane isn't helping. |

Same measuring blocks, same way, both files. HPFP and LPFP request and actual. Didn't we already see with the stage 2 log that high pressure actual is below requested, and lambda is adding 25% at wot? What else do we need to know? Lower the charge pressure, or upgrade the HPFP. |

Why does he have the ignition retard?
Is it because of the maf size?
I dont know the diameter of the stock maf because its oval, not round circle.
Im out of knowledge

Can't know for sure but, these things come to mind? 1. 91 octane and/or overly aggressive ignition timing/boost profile. 2. Fuel system that can't keep up. It's adding 25% which is all it can do. Clearly it needs moar. 3. Engine health Why is/was there all this focus on the maf? I rarely see maf's fail on these. |

The engine health see good, motor now has 250,***km follower replaced when I did motor swap, I did notice my themostat wasn't ready correct, I am replacing that this weekend when I have a few days off, so 91-v-power isn't the same as 93-v-power

Friend of mine mounted bigger intake/diameter@maf in his mk6r and he had -12degree across the rpm range instantly! |
