Title: Anyone knows what these maps are ? Post by: Blazius on June 19, 2019, 12:52:45 PM Title. Are these SOI maps or something lol? There are 8 of them in total. They are slightly different to eachother in some areas.

Title: Re: Anyone knows what these maps are ? Post by: Blazius on June 20, 2019, 12:15:05 PM post the file rather? I mean sure, but why would that help, unless you dissassemble it, and I dont think many people would do that for me :P also if you havent read my other posts its an 1.8 not a T.( well it is now I suppose but thats beside the point :D) None of the 1.8t ecus have these, well atleast in the same relative location.

14E23 KFKHFM 14F05 KFPU Pulsations - Kennfeld 14FE7 KFPUKL1 Pulsations - Kennfeld etc etc As per an NA ME7 FR: The pulsation map is used to compensate pulsation errors of the HFM; it is not intended to correct errors in the reverse flow range. Definition of pulsation range: Voltage oszillation of air mass sensor HFM < 0.5V Definition of reverse range: Voltage of air mass sensor HFM < 1.0 Adaptation of the pulsation map: - Definition of the pulsation range; poss. distribution of interpolation points of the pulsation map for better coverage of the pulsation range In fuel systems without constant differencial pressure upstream of the injection valve (e.g. RLFS), i.e. where the pressure regulator does not operate against the intake manifold pressure as a reference pressure, this must be specially guaranteed for application of the pulsation map (connection of the pressure regulator to the intake manifold). If this is not possible for technical reasons, the varying pressure differential upstream of the injection valve must be taken into account beforehand in a correction map (see note on RLFS systems).

Ive completly missread. I defined KFPU back when i was starting out finding maps a, but I didnt save the bin as I started from fresh and discarded the WIP project. I completely forgot about it, thanks. Btw I dont fully understand the purpose of this map. The FPR on car gets its pressure from the manifold.. Does it not get the pressure in the Alfa romeo that FR was made for ? |
