The photo was mine.
I'm on here as well... I still don't understand why you want to simply use the sensor you have in a different MAF housing. Rather than simply using a different MAF sensor/housing and using it's respective MLHFM.
MLHFM is tied to the sensor/housing pair.......not just the sensor.
What MAF are you trying to use and what car is it going into?

Nyet- I have read the S4 wiki many times, thank you for your hard work, great job.
Mmmboost- I was really just curious. I appreciate your awesome pictures. Listen, 6 months ago I had no idea about eeproms, ecu, hexadecimal, etc. I'm just trying to learn all I can. This stuff is just starting to make sense to me....sometimes. The fact that I can respond to you all and follow what your saying is a friggen miracle in and of itself. And honestly, housings are a dime a dozen, and sensors get expensive. If I can find less expensive ways to do things, I will....no, I rarely ever shop on eBay for car stuff. I'm just trying to learn.

I am still a bit confused on how ME7 handles load >191... got any advice/insight?
The ECU internally has an 8 bit and 16 bit representation of load. The 8 bit value is limited to 191%, the 16 bit value is not. The limit of 191% load is only for the systems and maps using the 8 bit value. I believe the 16 bit value is used almost everywhere, except when it needs to do a lookup on a map using an 8 bit axis value. |

rl (0xff*.75=191) vs rl_w (0xffff * 0.0234375= something big) ?
i.e. 0x00F98B vs 0x00F990 in mbox?

Correct. VagCom measuring blocks only show you the 8 bit value. You have to use a RAM based data logger to see the 16 bit value. |

Audi s4 v8 maf should work for that setup. For the time being you could try dialing in KFMSNWDK/KFWDKMSN then moving to FVVKS (within map limits). Then beyond map resolution go KFLF first or KLAF. Rescale torque model maps and you should be setup to dial in the new maf.

When you are changing from tt 225 maf to rs4 bosch maf which maps should be copied?
MLHFM
MLOFS (keep it 200?)
MLFHFM?
KFMLDMX?
MLMAX?
KFKHFM?
FKKVS?

You just need to change the scaling the of the MAF initially, MLMAX may need to be increased, KFMLDMX if you get the engine check light , but if you're going with an RS4 maf you must be running a bigger turbo and a lot more maps generally need to be changed. |

Thank you
I am upgrading from gt2860rs to gtx 2867r so the maf will hit its limits.
If I am not wrong the tt 225hp maf's limits is about 290 g/sec
