Wow-alot of interesting talks, thanks!
But maybe somebody tell me-what codeworte i must disable in me7 with MAFless, for switch back motronic from limp mode to normal mode? I dont whant to use external boost controller etc.
x2 I'd really like to know how to prevent the ECu from throwing itself into limp and also allow the ABS/ESP to function without the MAF's load input anymore |

For ABS/ESP you have to tune CAN coding on ECU. ECU sends signals to ESP module via CAN and when MAF is unplugged then ESP goes OFF. You can have ME7 boost control with MAFless of course, torque model is still there...  |

But when MAF is eliminated, there will be limp-mode in motronic. Same as in situation, when EGT sensors or front lambdas fall. In limp mode, there is only about 1440 millibar of requested boost, regardless of what we have in LDRXN map. Or i am wrong and MAF absence is light error without limp mode (like second lambdas error for example)?

Exactly, so how to prevent this? |

Any further thoughts on coding out the maf, so that ESP/ABS doesn't freak out

Mantis, run a maf, pre or post turbo doesnt really matter much because even the rich condition on shifts can be tuned out with the pre turbo setup and a bov, if you are running re-circ then all the better/easier for you. I am ordering the pro-m 3" tube soon. look into it, the price is right. it is intended for blow through and i really suggest you go this route if your plumbing is setup to allow it. both turbo and bov must be before the maf for the blow through to work right.
Btw- i am not knocking on any poster here, because everyone has a right to post whatever they want, but I wish there were less winks and leading talk and more actual tech on posts like this. a few of you in particular are telling us you know for a fact how to do something and that it will work well on the 2.7t and 1.8t. instead of flexing your e-knowledge muscles maybe actually tell us how to do it.
not a demand, just a suggestion from another user and thanks you for the information you have provided, however vague it may be.
sorry for the thread jack, my opinion on the main topic of the thread is that I have built all sorts of crap new and old, the stuff with a maf always runs the best. dont defeat great tech when you can set it up properly for any setup. my $.02

^^^ Agreed with everything you said. That said, I think I'm going to copy julex's setup: |

I just don't have the room to run it on the inlet, the outlet is not ideal either |

So how am I supposed to look at the code if all I get is "I am using the file which prepared by myself." What is the exact numbers of the software?  |
