I do have a stock airbox so I'll have to play with MLHFM. I gather I should compare it to a more stock scalar and mod back that way.

A straight scale may not work either, and you also may need to massage KFKHFM... sorry man, but the AWE maf housing is just really really honking weird.

You'll likely need to drive around a while and log your stfts at various rpm/load points. Don't forget to disable LTFTs before logging STFTs!

Thanks, I don't have a B box image despite searching. Sold the stock one long ago.

70mm inlet, 100mm at sensor. It is very very non-linear.

It's completely whack. They kept making bigger and bigger housings because they couldn't figure out how to do anything w/o crazy underscaled load.

Honestly, for the price of a straight housing, I'd just grab one. Unless you are SUPER budgeted, that's the way to do it. I have a few kicking around, I'll give you one for what I pay if you pm me.

From 551B:

0x14ECC

00 FC   E0 FC 0C 00 F0 FF    AA FA 55 55 55

Replace the string at 0x10C75 in the L-box with the one above. Most of it will already be the same.

Unfortunately I'm still getting the

18321 - Pressure Sensor for Brake Boost (G294): Short to Ground
        P1913 - 35-00 -  -

after that and modifying CDBKVP instead of CDBKV. What is the address of for CDBKV so I can be sure I'm modifying the right value?


After that comes the logging and attempting to deal with the MAF issues. I keep telling myself it must flow more than stock so its worth it....

Ok, from what I read setting NORLA to 5 is the way to disable the LTFT's. What's the address for NORLA in L/M? It's not in the M xdf file that I have.

I've done some basic logging and I think the fueling is OK. When things go open loop I'm seeing a higher O2 voltage, like .8 V or so.  My noob understanding is that rich, do I need more? I know, I need a wideband but its going to be a bit before I have the time to deal with that.

TIA, Al

Oops. I found a thread  with NOLRA at 0x18CD5. Hopefully that's right
