ECMlink general; how close is your gauge/logged AFR at wot?

[miliman13]

Again this is just general.
At WOT how close it your log to your wideband gauge?

Are you dead on?
A bit off ?

My gauge is calibrated and dead on at idle and cruise.
Towards the end of my wot my log says 11.1 but my gauge says 10.3....

Keep in mind, this is just what i remember glancing at during the pull.

Just looking to see if this is common.
Thanks people.

I have an innovate mtx-l wideband, and my WOT pulls logs almost spot on. My WOT target is 11.8 (e85) and my gauge matches what my log says. However, at idle there is some variance because it is constantly adjusting and too hard to match every spilt second.

What gauge setup do you have? I have a the MTX-L wideband and my tuner said the same thing about my WOT readings. The log and the gauge are roughly .8 off on mine as well.

I'm also curious to see if placement matters in the descepinces. I have my mtx-l in the stock o2 placement simulating narrowband and wideband.

Mine is located in the gap between the engine and the subframe on the down pipe, shouldn't make a different from having it in the stock located on in the recommended distance(unless you have an exhaust leak).

Yeah, that location shouldn't make that big of a difference. However, the further away does increase the lag in accurate reading. Like one in the rear o2 location won't be as accurate as where we have ours.

I'll see if I can post a log and have the wife take a picture of the gauge tomorrow to show the accuracy of my wideband.

I have the AEM eugo.
Tapped in a few inches down from the O2

Yup, I know nothing about AEM widebands besides what has been posted about them, mostly negative about their accuracy.

I have been using innovate for the past 2 years in the stock o2 location without any problems.

As of today during a pull, my target afr was 11.8 and my wideband read 11.8 on log and gauge.

How's your wiring to the ecu, like soldered, crimped, or etc? I know with innovate most of the problems with inaccuracies is with the wiring to the ecu.

It's common for the AEM to be off in the log. It will be more accurate if you set it up as linearwb.

Yes soldered and heat shrink.

I found the Video corey made.
Incase some one else needs it.

You want things to track as closely as possible, and yes you "ideally" want your WB to match between gauge and what is logging. Mine doesn't.. but just because I took a shortcut doesn't mean that other people should.

 

[miliman13]

Well i followed the video and my gauge and captured value do match more closely at wot.
So it appears my gauge was correct and link was showing a bit leaner.
Now they both appear around 10.3-10.6


Ill lean out more on the VE. to see 11afr on both.

just to mention these are my numbers.

14.7 AFR = 2.66 Volts
11.0 AFR = 0.90 Volts
