Maybe someone knows the answer to this.
I use Innovates LM-1 WB with DB gauge.
The controller has been back to the factory for calibration, its calibrated with the sensor and DB gauge.
This is dead on between the controller and DB (meaning the readings are the same.) Accuracy of my wideband has been confirmed. Been driving and tuning with this and my new engine since April.

So last night I decide its time to connect back up the the EBL. Connected it to channel one, set my preferances to 0-5 volt. Went into channel 1 of the LM-1 an set those properties to 0-5 volt

But in the EBL software it never matches what my controller and DB gauge read. Now I'm not talking less than 1. We talking at times in about 4 points off. This is making me begin to wonder about the accuracy of the EBL software. If its not reading from the LM-1 controller correctly how do I know its reading all my other sensors correctly? I don't dare do a VE learn using the WB feature, if I did that then I'm sure that my .bin will be on the rich side.

Any insight to this I would really appreciate your help as to why did does this. I hate to question it but can't help to after seeing this.

This is a very short video of what I'm talking about. Thanks

I had some similar issues however not nearly as bad. Did you follow the instructions on grounding? If not for detailed info check out Innovate forum and search on ground offsets- you will find all info needed to correct this. Also the preset on EBL for the LC1 0V=10:1 5V=20:1 , you can make a custom defined parameter 0.000V=7.3500:1 and 5V=22.3900:1 this also was an issue because the newer LC1 is defined that way on analog 2 out by default, analog 1 is set to lambda on the LC1 by default. Hope that helps.

How do I make a custom defined parameter in EBL?

JDUBB

Open EBL whats up. Click file/user devices now enter the name for the device (whatever you want) and put in the fields the 0v=afr and 5v=afr as described in my previous post then click apply. Then click preferences / adc channels and select the custom definition viola good to go,. Another thing when at lambda 14.7:1 your stock narrowband should be at 450mv so when you datalog in closed loop swinging back and forth 300-800ish look at your narrowband vs wideband when the narrow band is near 14.7 (450mv) your wideband should be 14.7 when calibrated correctly and good grounds and (in correct places). Good luck I spent several days getting it all calibrated correctly so EBL would correspond with LC1 gauge and also matched stock narrowband at lambda.

Version 2.2a and up WUD has User Devices. ALT-File, U for the dialog.

6/30/2009 v2.2a

Added user defined analog linear input devices, up to 16
Kept all current WB & fuel pressure devices
Added ability to assign a device to any channel(s) (Preferences dialog)
Added ability to define WB or FP sensor as preferred, for VE Learn and WUD displays

RBob.

I reset the parameters in EBL according to channel 2 of the LM-1 0v- 7.35 and 5v=22.39. Still reads 1 to 2 points off.
Should there be a seperate ground connection to chassis at the terminal board?
or maybe the speed of the EBL isn't as fast as the LM-1?
Just some thoughts I had...
thanks for the replies

Well, ground offsets effect the readings quite a bit so check the forum over at innovate on offsets The instruction from innovate contradict each other so that can be confusing, depending on what you read one says separate ground from gauge another says same, so from experimenting I found your gauge and controller should be grounded to the same place preferably the engine block. I grounded it to a bolt on the rear of the cylinder head and for ease of installation ran a single wire into the cabin and attached grounds under dash (less wires under hood =cleaner install). I don't think soldering is needed as innovate may suggest, I just crimped everything nice and tight.

I agree with those ground connections. Thats what I have already set up and the controller and gauge read fine.

Let me revise my question.
Should I extend that ground to the ground on the terminal strip inside EBL's ecm?
thanks

I was able to get things agreeing correctly by creating a custom device in EBL same voltages I posted earlier, and grounded all to block then voltage matched, I also set the filter at 10 in EBL and left it default on the Innovate. I did not ground to EBL, I may be wrong about the grounding however it did work for me after trying different ground location ect.... Block at same location was best for me. You can manipulate the signal to EBL by adjusting voltage vs afr like Rbob posted. If you search the forums here there is a lot of more info on this. Read tuning with EBL thread 3 hours to read all but well worth it!
