Does anyone have the memory address for uushk_w in 4Z7907551R so I can log my wideband with full resolution through the ecu?
I'd post the ori bin, but it's a very common file and I don't want to unnecessarily take up server space.

If I remember correctly your car uses wideband o2 sensors so logging your front o2s and requested and current AFR will be an accurate wideband reading.

I'm confused, if you are using the ECU, you have a wideband, if you aren't, how is the location valid?

nyet, 551R is a narrowband ecu. I have an innovate lc-2 that I am attempting to log by running the signal through the rear o2 sensor (rear o2's coded out)
You can't just log the normal o2 voltage variables (ushk/2, 8 bit) as they are capped at ~1.3volts. I need full 0-5 voltage resolution to log my wideband, and uushk/2_w (16 bit) will give me that resolution... at least that's what I think based on other examples.
Will report back.

I can now log a 0-5v signal through uushk_w, instead of ushk.
ushk gave only a 0-1.3v resolution and required scaling the output of the lm-2, resulting in inconsistent samples. It was good enough to let you know if you were rich or lean, but not a very good indicator of actual lambda.

ah i understand. I thought the output impedance wasn't low enough to drive those narrow band inputs?

link to how to install nefmoto? thanks no, but if you download the folder there is your ecu file with what you need I see you figured that out |

For the one millionth time. THERE IS NO 2.7TT WITH WIDEBAND.
Thanks.
