Hello,  I'm new here. I want going mafless in my s4 b5 because i'm going to do over 600hp on gtx35 turbo. I read about mafless but i have obscurity. I can disconnect maf and already tune any map? Which map i should tune after doing mafless so that fuel would good? Is the car will work correctly, while map sensor is before throttle plate (not see the vacuum)? I come up with an idea to connect the maf cables to the map sensor connector after the throttle plate and scalling the maf map for this pressure that ECU would be able to see vacuum beyond closing throttle (would be two map sensors). Whether this would work? If not, how to do the classic mafless in order to my s4 to work properly? Best regards Mateusz |

I don't want standalone. Standalone take away a lot of facilities that for example have Motronic. My car will be a street car. If I want to have standalone I'd not be writing this post on the forum. |

There are numerous threads about this on this forum, just search.
You will lose traction control though, just keep that in mind.

If you want the traction control back, I have a solution I imagine a coding change to supply load after all .. I might be academically interested in it... and maybe even empirically since I would love to feed turbos directly from two cone filters instead of screwing around with y-pipe et al. |

Could someone write anything like a tutorial? What maps i should tune after mafless (mainly fuel)? And if there is a possibility of tune up the car at closed throttle?

 I wouldn't expect any tutorials if you don't even want to read threads already posted about it man.

If you want the traction control back, I have a solution I've been researching MAFless, and I think I found out how. But I would love to know how you do it if you care to share. |

In almost every thread I read: "Not for free". This is already the world. I wrote "like tutorial". I'm from Poland and certain technical words be tough to me. Thread can be closed i guess because leads nowhere. My poor ideology of two map sensors come to grief. |

Two MAP sensors will work but requires re-write of ECU code. Again, not for free |

You should just put that in your sig Kinda cheeky of you don't you think? Considering the amount I've contributed to the forum. Yeah sorry, I am not going to spend my time working specifically on something you need for free. I have enough cars to tune for paying customers. |
