Hi,

I have an Innovative MTX-L and Crome Pro 1.6.5

I have noticed that the wideband gauge is showing different readings vs the datalogging on the laptop when I compare the two simultaneously.

Is there an offset somewhere?

This is on a p28. I'm using the yellow wire from the MTX-L output, and have not made any changes to the output.

Is the p28 expecting a slightly different voltage range?

 

Go into File/Settings/Tuner Logging (tab) and adjust the Lambda offset until it matches your gauge readings.

 

is the wideband grounded to the thermostat?

 

No, I grounded to the chassis.

But the thermostat is also grounded to the chassis.

You think that's it?

 

I already did that.

What voltage range does the Honda ecu look for from the stock o2 sensor?

 

I did some digging and the default outputs for the innovate are yellow (0v=7.35afr and 5v=22.39afr) and brown (1.1v=14afr and .1=15afr).

I went back into Crome and I can't decide whether to change the output of the wideband or what Crome expects.

What do you guys suggest?

* I went ahead and changed the settings in Crome for tuner logging to Innovate and then just plugged in the numbers for what the default Innovate pulldown has and saved the changes.



What about the lambda recording conditions range?
What do you guys put in there?
If all else fails, I guess I can readily apply the offset lambda correction too.

 

If the drop down scalars in Crome do not match what you have for your widebands specs, I would change them.

As far as the lambda recording conditions go. You can change them to whatever you want. Depends on where you want to record your AFRs. I have mine set so that it will record pretty much all the time.

Throttle: 0-100%
Lambda: 0.60 & 1.20
Engine speed: 0-10,000 RPM
Engine load: 0 - 3000
Water Temp: 40 - 250 °C
Gear(s): 0 1 2 3 4 5
