MAF (165, $6E, APYM) VE tuning
Am I missing it or what? Where are the VE tables to adjust? My BLMs are a tad bit high. I've tried searching and couldn't come up with anything. I'm using TunerPro with the 6ev009.ecu file and an APYM-based BIN.

There are no VE tables in MAF stuff. You'll probably want to look at the BPW Fuel Vs. Load table for adjusting that.
But FIRST!! Read this post https://www.thirdgen.org/techbb2/sho...hreadid=133967

Ya know, I had started to read that at one point but saw that it said "$32 and $32B" so I figured it wouldn't apply to $6E. Thanks for the heads up though.. now that I've read through it, I see it does have a lot to do with $6E too

Sorry, I completely missed the fact that you were running an 89 bin.
From what I've read the only have 2 ways to change the fuel (exc. PE and AE) The injector size constant and the MAF tables.
Let me see if I can find some links I was looking at about it...

Thanks.
All of my BLM readings were quite lean at first. Then I upped the MAF tables 8%, and then again 5% in the next burn. I finally decided to drop my injector constant from 19.48 to 18.50, and now all of my cruise BLMs are 3-4 points high at 24, and at 48, my BLMs are within 3-4 under 128.
PE shouldn't kick in until I'm in the 72 range, so it shouldn't be enrichening anything I don't think. Am I correct in saying this?

I've decided I'm going to wait until my EEPROMs come in the mail, and then I'll start with the stock MAF tables but with all my constant/flag changes and I'll start tuning my changing injector constant first to get BLMs close instead of changing the MAF tables so much. It seems that people suggest doing that first.
