How to connect a MTX-L Plus wideband digitally

[AREA876]

Did a custom conversion and got the analog to match but digitally that's where I'm having the problem

Can you show me what it reads when set to LC1?

Analog 3 is my wideband and it was reading 2.28 when the innovate was reading 0.97 lambda

What have you programmed with MTX analog output as? Mine used the change every time the connector got wet...

Custom conversion I was using at the time. Please ignore the highlighted AF as it was set to the wrong input.

The default innovate values are 0V = 0.5 and 5V = 1.52 Lambda

[Hondata]

Yes, but what are the actual values the innovate has? Like I said, mine used to change on its own.

Values have not changed, I have never had a problem with values changing and I have owned two LC1 and a MTX-L

So now switch the analog input to voltage and check it matches the lambda.

I've checked and both the KPro and KManager use the 0.5-1.5 lambda range for the LC2 analog input. So they should work.

So is only the digital input the problem? In that case can you set the analog to LC2 and compare the digital to analog when both datalogging, and also by making a datalog on the KPro and then loading into KManager.

Thanks. It is something with the digital stream which is different from the LC2. I'll try to get Innovate to respond again.
