ECMlink LC1 AFR Doesn't Match DSMLink Log

[Nate355RS]

I've just converted to SD using ECMLink's plug and play cable and gone through their wiki and the how-to threads here but I can't seem to get my LC1 to match what DSMLink logs.

Here's what I know and what I've tried so far:

1. Wiring
White wire is grounded to ECU ground
Brown wire to pin 4
Yellow wire to DB gauge's white wire
Blue wire is to chassis ground, same ground as the LC1 gauge and calibration wire

2. Default for the LMProgrammer showed the settings as 0-5.0 volts and 0.5 to 1.52 lambda. I set both analog outputs to these values and made a LinearWBO2 sensor in DSMLink that matched

3. Gauge reads about .2-.5 off what DSMLink reads, BIG difference.

4. Just to make sure, I hooked my laptop up to LogWorks and its serial reading was also different than DSMLink, but not as bad as the gauge. Eyeballing it looked to be about .2 off.

5. I've done a free-air calibration of the LC1

6. LC1 is in the front 02 location and I'm running DSMLink's NB simulation

All of my wired connections are soldered and have heat shrinks on them. Could anyone help me find the issue? I apologize if I left out any important information.

You need to go into logworks and change the voltage points and also do the same in ecmlink till they match up alittle better.

I'm not too sure how the voltage affects the log. I tried playing around with it but every change I made seemed to make it worse.

Ecmtuning recommends the yellow wire to be taped off and unused since you are going to run narrowband simulation. What do you mean by "DB" ?

I teed off the brown wire. Run it to both the lc1 gauge AND your front(or rear) ecu input. I had the same damn problem for a long time until i finally just ran it per link's site recommendation and T'd off the same output wire. Last time i fired it up and ran a log, both matched perfectly.

Phantomdsm's link is exactly what you need to follow. Do exactly as it says and it will work perfect for you. Lmconfig is the worst program ever written. Its hard as hell for most people to actually get it to hook up in the first place. Took me a bit. then running it over and over and messing with links voltages etc etc. Its just stupid. That needs to be stickied as THE method for lc-1 wiring. No need for lmconfig at ALL.

The DB Gauge is the name of the gauge that shipped with my LC1. I wired up everything according to the link below. Tomorrow I'll try cutting the yellow wire and running the brown to the gauge. Fingers crossed, trying to calibrate this thing is getting frustrating.

Duh the DB is the name, my bad Cool let us know, check out the link i posted above, Hopefully that will fix the issue.

I finally got the gauge, LC1 controller, and DSMLink logs to match. Because there's no really easy way to log the gauge, controller, and DSMLink WB in one program I found another way to compare their values.

I ended up taking a video with my phone. I put the the gauge beside my laptop and positioned LogWorks and DSMLink on my desktop so I can easily see their AFR values. When I played back the video and paused it, I could compare all three values at the exact same time.

So after I studied the video, I found the gauge and controller were identical. The difference I thought I saw yesterday was a split second lag between the gauge and LogWorks. But after going over about a couple 15sec videos I'm convinced they're showing the same value.

After that I calibrated the LinearWB sensor in DSMLink to match my controller. The LinearWB was showing about .4 higher than the controller. So I had to go into the LinearWB preferences and increase the min voltage to 0.07 and everything lined up great. I'm sure there is a mathematical art to figure out the voltage offset but I just used the trial and error method and .07 worked for me.

If someone else has this problem calibration problem, you need to increase min voltage to bring the LinearWB values down, and decrease max voltage to brin LinearWB values up.
