Sorry, didn't look at fuel. Should have.
Lamba control is maxed out. Definitely something wrong. Might not be the MAF, could easily just be a vac leak between maf and turbo inlet.

Thank you so much. After your fast reply I checked the turbo intake hose and found that my cheap ebay BOV, which was supposed to send air both into the atmosphere and back to inlet hose, has no border between the two exits. So my turbo was sucking air from it (without any filtering :X) and messing with MAF readings. Now the maf easily reads about 139/140 which is still bothering me that this value is not what it should be. But thanks to You guys I'm a step closer to perfectly mapping my car. |

Don't use a vent to atmosphere BOV, use a recirculation valve like oem!

2nd. Ditch the BOV, you'll have even more MAF issues down the road. There is zero benefit to BOVs, and in MAF cars, it is doubly stupid because you are venting metered air. Whoever started this unfortunate fad needs to DIAF. |

I've installed an LPG system but now I can't make logs. It seems that LPG ecu interferes with cars ECU and ME7logger doesn't work. And do the LPG ECU makes its own timing corrections or I have to change kfzw. 10x

Another noob question from me here. If I flash stock file and log MAF readings, which I expect to be lower than they should be, can I then calibrate it to show maximum of 130g/s ~~~ 163hp. 10x

I found that my MAF is 11% off. Until getting new one I tried to increase MLHFM by 11% but then the car won't idle. Is there a way. Anybody. 10x

Why did you add an LPG system to an ECU you can't even properly mod for a different MAF?

Well, there is only one straight answer....... Money Savings! Here, Petrol price is over 1.2$ per litter and LPG is barely touching 50 cents per litter. My MAF is not different. It's the original one the cal lef factory with. It's just old and off correct readings. Info about MAF scaling here covers mostly same MAF diff housing but not diff MAF same housing. That's why I can't still figure it out. |

I did another research and what I understood is that I should subtract all Values from MLHFM by 200(MLOFS) then multiply by 11% offset, then add 200. Am I correct? 10x

Searching for help again ..... New MAF installed, OEM DV installed, turbo checked(perfect condition)... still low MAF readings, even with stock file. It looks like vacuum leak after MAF still. Where to search and how to test. Thanks in advance. |

Could somebody take a quick look. It's not raw .csv it's converted... sorry for that but I replaced the original file and lost it. There's not many variables so it's easy to read. 10x in advance!
