Oh I will for sure! Probably the weekend I'll get a few things on the car finished and start tuning. I have an LC-1 Wideband setup with Narrowband out going to B1 O2 sensor. |

Good to hear that it's working out so far.
Does the trimming appear to be behaving normally?

I think so. I should have some logs tomorrow morning.

I flashed my ecu just now with the "mono" lambda sensor changes.
I can confirm that both banks show exactly the same O2 voltage, with only the Bank1 hooked up to the wideband.
Good work!

$260 shipped, I just ordered the PMAS, wiring pigtail and aluminum weld on flange. I am finally going to convert to blow through and hopefully get rid of the no-ideal intake setup.

I am kind of nervous about the transfer function I came up with. Hopefully it will be a good place to start.  |

File I was messing with: see MLHFM
Using the HPX maf tool, calculated for 3" pipe......30 points transfer
Interpolated the 30 points to 512 for me7. The Low volt region .01 and a few points above have me kinda concerned. When I interpolated them I came up with a bunch of negative numbers. TunerPro made them 0, which is fine, its just something I think I m going to have to keep an eye on. I really need to start using ME7L so I can log MAF voltages, or better yet use one of the inputs from the zeitronix.

MLOFS exists so that MLFHM can be all positive.

More specifically for return flow detection. |

I'm using the HPX sensor too and the MAF curve I ended up with is a good bit different than the interpolated curve I started with. However I'm using a mostly stock air box (just with holes cut in it) and with KFKHFM all set to 1, so I kinda worked the airbox's flow characteristics into my MAF curve. There's still a few rpm/load spots I have to fix up with KFKHFM but overall I think doing it the way I did got me a much more accurate reading with my set-up. I would definitely suggest trying to get ME7L working, being able to log MAF voltage, g/s, fuel trims + Zeitronix AFR made getting everything dialed in pretty easy. |

Would you mind sharing your Mlhfm? |
