Title: Bosch me7.5 Post by: laringa on January 17, 2016, 01:28:16 PM Can someone tell me how much power can do through 80mm airflow sensor connected to bosch me7.5 ecu?
Title: Re: Bosch me7.5 Post by: adam- on January 17, 2016, 04:00:44 PM Airflow is not a direct measure of power. Log MAF voltage and see if it's pegged. I'd say atleast 450.
Title: Re: Post by: laringa on January 17, 2016, 09:17:46 PM Is it possible to run the me7.5 on a TT without MAF as it is the only sensor that measures the load
Title: Re: Bosch me7.5 Post by: aef on January 18, 2016, 12:26:37 AM Yes it is, search for "mafless".
Title: Re: Bosch me7.5 Post by: adam- on January 18, 2016, 12:41:49 AM It's a hack though. There's no good reason not to run one, there's loads of space for one.
Title: Re: Bosch me7.5 Post by: littco on January 18, 2016, 02:48:41 AM It's a hack though. There's no good reason not to run one, there's loads of space for one. Hack yes but a good one. 80mm maf is max grams of 292. But you need to appreciate that maf is converted in principle to load and that is used for axis. Therefore you can run more than the theoretical max but you axis's will stop reading after max load is reached.. 490bhp has been run without issue on a 80mm maf. It is better Imo to fit an s4 maf and rescale the maf to account for this and associated load axis Title: Re: Post by: laringa on January 19, 2016, 10:41:41 PM Iittco thanks for this info and i would like to do as you described but i am very new to tuning the me7.5 and dont know how. Can you help?

Title: Re: Bosch me7.5 Post by: adam- on January 20, 2016, 12:07:20 AM I don't understand any advantage. There has to be some room in the bay for a 4" bit of tube.
Title: Re: Bosch me7.5 Post by: dream3R on January 20, 2016, 01:35:52 AM some people prefer alpha-n. Especially big builds. Read GGHFM carefully as there are limiters there / RPM etc..
Title: Re: Bosch me7.5 Post by: nyet on January 20, 2016, 10:13:37 AM I can't think of many 1.8t builds that make that kind of power. Not only that, it would require replacing the stock MAP sensor, and all that that implies as well.
Title: Re: Post by: laringa on January 20, 2016, 11:49:02 AM I am running with stock maf. Just asking how much power can be done. Its a good idea to upgrade to s4 maf but i am new to tune bosch me7. Any help/suggestions apreciated

True it depends on how driven he is but it can be done but ur right not for a noobTitle: Re: Post by: laringa on February 09, 2016, 11:53:38 AM Nyet. There is no map sensor in 18t it is a boost sensor. In only read positive pressure
Title: Re: Bosch me7.5 Post by: nyet on February 09, 2016, 12:53:14 PM By MAP I mean boost sensor, sorry, misnomer. Bad habit.
The stock boost sensor only reads 2.5 bar max. |
