I would be amazed if bosch designed this oh so familiar looking piece of hardware specifically for motorsport use... as the volumes would not justyfy it. What it looks like is familiar Me7, offering assorted inputs and outputs, and the mapping software is very familiar in contruction but more detailed. It would not support maf for motorsport use. Given this is a high end ecu, and the thick end of £2500 plus extras like dbw support, wideband control etc etc, it would only be professional motorsport teams who could afford to use them. Point being, you dont need a maf to properly tune an engine |

Be careful with your definition of motronic. There are ME7 ECU's that from the factory that have no MAF and use MAP as their load base. Point being, you dont need a maf to properly tune an engine Other than on a system that was designed to be use MAF as its load base. |

The thing is, it does not really run traditional speed-density when you remove the MAF.
It pretty much runs alpha-n with enhancements.
Agree. ECU runs ONLY in alpha-n as the MAP sensor is located outside the manifold... the files I saw make you run alpha-n (with an small map by the way) pretty rich and you Wideband (when it is present) does the rest of the trick |

Thanks for additional input, I was not aware than running a mafless setup would perhaps interfere with the ABS system of the car. That in it self is a risk I would not like to take.

If MAFless is what you really want, you would be better off to just run a standalone ecu, like the Vipec plugin ecu.  |

After a year, I am still waiting to come across any issue on my ME7.5 running MAFLESS on a +500whp BT 830cc setup.
Still have great mpg, smooth throttle response (idle, part, and WOT)...Have LC and NLS coded...will be swapping to 80mm TB shortly for further optimization...Have no ABS/ESP/ASR issues and have full cruise control functionality...
Have actually not noticed any difference in how the car feels by running alpha-n...

I still don't understand the point to it, unless you are running standalone or a motorsport ecu which is designed for it.

from reading this, it went to wrong direction... the question is "can it be done" and not "is it smart or stupid to do it".. ...I do not understand, why so many discussions in different forums make the same mistake  ...imagine you go into a pup an order a beer... and you get an education about the harmful effects of alcohol consumption from the tender  ...so I will bump up the question again... can it be done and what to do in Me7 to make it ... (without judging about it)  ...reason maybe.. you have no space for mounting the MAF... |

But you have to dial in a new MAF curve in ME7... but no Space on pressure side either :-( |

Also complaining about dialing in a MAF - are you kidding me? but no Space on pressure side either :-( This I don't believe. On a 2.7TT there is plenty of room pre-turbos and on all the four bangers there is TONS of room everywhere. The fact that you can't do it right means you are just lazy. |
