22.4% oxygen on gauge = not working. (22.4% means the controller thinks the sensor is in free air and not metering any fuel whatsoever)

7.38AFR in TS = no signal.

No now that you are not reading 22.4 it is probably not the wiring. (although make sure it is grounded properly) it looks to me like a setup issue in tuner studio. Hopefully someone will get on here with some insight on that for you.

You will probably need need to manually adjust the calibration in TS for the wideband. In the instruction book for the wide band it will give you what voltages match to what AFR. You can do a custom calibration and put those in. You will probably have to try slightly different values from the book to get the 2 gauges to match.

use .22v = 7.35 and 5v = 22.4

gets you pretty close, but 2 full points off from gauge to TS seems pretty far off, it's usually like half a point at most.

So would I leave my wideband on LC-1/LC-2 and adjust the values, or do I need to select linear WB and input the values myself?

One thing I have not done is hooked my MTX-L up to logworks. Is that a necessary step? I assumed I wouldn't need to do anything in logworks since I had MS.

Also it seems I'm not the only with this issue of 2 different numbers :http://www.msextra.com/forums/viewto...?f=131&t=61483
I'll do some more research as well.

try that as a custom calibration in TS, see how close it gets you.

I just want to be totally sure.

I should write these values to the controller?

Yes. But expect to have to do this a few times to get the 2 gauges to match.

To better my understanding, do you mean I'll have to write to controller multiple times to get the settings to stick in TS, or will I need to turn the car on and off multiple times after I have input the settings to get them to match up?

No...you will likely need to try multiple times with different numbers to get it right.
write to controller once and test. repeat with different values until the gauges match.
remember that your mtl-x gauge is correct you are changing the TS gauge to match

So should I leave the AFR's the same and just change the volts? I don't know what range of values is safe to input.

I found this post over at MXExtra, does this information help at all? (Megasquirt Support Forum (MSEXTRA) ? MTX-L and MS3 - some interesting readings. (View topic))

Quote:
Here's what I got on the first try:Code: Select all
Code:
MTX(v) MS3(v)
0 0.01
0.1 0.11
0.5 0.52
1 1.02
2 2.04
2.5 2.55
3 3.05
4 4.07
4.5 4.57
4.7 4.78
4.8 4.88
4.82 4.90
4.90 4.98
4.92 5.00
I ended up with 0V=10, 5V=20.1 in TunerStudio to get the physical gauge to match TS's gauge.
When I input the 0=10 5=20.1 settings, TS reads 12.4 and is stuck. The gauge is bouncing from 12.6-13
When I input 0=9.5 5=22.39 TS seems super close. the gauge is reading from 12.6-13 and the decimal is moving fairly quickly. TS is reading basically 12.5/12.6. When I give it throttle My car dies and gauge moves to 22.4 and TS moves to 9.5
Hit as high as 13.2 and TS never left 12.5/12.6.

I'm no expert but I think you still have a problem 10 - 20.1 AFR isn't the complete range. Hopefully one of the experts will chime in....

I played around with a lot of numbers in TS, and I couldn't get the AFRs to match up. I have to go to work right now and on lunch I can grab a serial to USB adapter so I can start messing around with the LM programmer.

Update: I got LM programmer and logworks setup. I have tried multiple calibrations. I have changed the settings countless times based on lots of threads. Nothing I do gets TS to read the AFR the same as the gauge. Logworks is reading the same as the gauge. Do you think this could be a grounding issue?

So update: I have redone my ground, soldered all the connections. I still have the same exact issue.
No combination of AFR calibration numbers for Custom WB gets TS to read my AFR the same as my MTX-L gauge. Nor do any of the default innovate settings.
My gauge and LM Programmer are reading the exact same.

What are my options now?

Where is the wideband o2 sensor installed? Pre-cat (near the header) right?

Can you plug in the stock ecu, leave the wideband installed, and drive around a little bit and watch the gauge? After startup it should read in the 13-14 range, and once warm should read between 13.5-15.0 or so. It should hover somewhere around 14.7, but won't be super precise since the ecu won't have the stock o2 sensor to properly calibrate, and it'll throw a code eventually. This should at least let you know if the wideband is operating correctly before throwing in wiring/megasquirt complications.

The wideband is installed in the normal location of the stock o2 sensor. When I installed the MTX-L I was advised on this forum to wire the power and ground into the MS3X's harness. Therefore, if the MS3X is unplugged the gauge will not come on.
