Afr innovate lc2

[Massimiliano]

Hi,

So I use the Zeitronix on the Brova bench. I just looked at the comparison values with the Innovate...

The Ecumaster control unit uses the Bosch 4.9 probe, but it doesn't have an external reader, it's integrated, and I can't see the values there.
But I see that the Ecumaster and Zeitronix read the same AFR in all conditions...

Having the Innovate connected to the Utcomp, I see a difference of 0.7/0.8 AFR, with the Innovate data... so a = 3.01 and b = 7.35

I wanted to "correct" this Innovate reading. Since Utcomp with Innovate is fixed in the car, I'd like to see the actual value of 11.4 and not 12.2.

Can I correct the Utcomp values to see the correct reading?
Do I also need to correct the Innovate values?

Interesting to me is the source of difference.
If you see only constant offset 0.7/0.8 AFR you can decrease "b" with 0.7-0.8 and you will get the same values:

e.g. b = 7.35 - 0.75 = 6.60
b = 6.60 instead of 7.35
