Title: mlhfmm_w to gs calculation... i want to be sure
Post by: Kompiesto on October 30, 2018, 06:54:37 AM
Hi,

I have VR6 car, tuned by me... anyway a lot of things is scaled and i modified st10 flash to get real readings of MAF before scaling data to diagnostic block. I found variable before MLOFS offset value substraction....

On WOT at 6800 rpm i have 18000 number in VCDS... after calculation like.. 18000 * 0.1 - MLOFS ( 200 ) i get 1600 value. If i am on good way, when i divide by 3.6 i should get 444 value of g/s.

Why asking about it... i want to calculate theoretical power using maf sensor... 444g/s should by around 555hp. Good thinking?

What is the maximum value of original MAF? Why in MLHFM i have values from 140 to 1464 only?

I have confused the data.... I get maximum 14464 * 0.1 -> 1446.4 -> ~433hp. MAF max value in MLHFM is very close my measured value. I heared that VR6 MAF is good for 500hp...my MAF is too smal for 500hp?
