I have a glowshift wideband with a bosch LSU 4.9 sensor. They gave me the following calibration info

0.00 Volt= 10.00 A/F
1.09 Volt= 12.18 A/F
1.25 Volt= 12.50 A/F
2.50 Volt= 15.00 A/F
3.59 Volt= 17.18 A/F
4.99 Volt= 20.00 A/F

I'm in the calibrate afr table in tunerstudio. My wideband in not in the drop down list, so I selected custom linear wb, and I need
to enter two points of reference "point1 and point2". Which of the 2 above should I enter in? the 0.00 and 4.99? or should I go with
the 1.09 and 3.59 set points? Thanks again for all the help guys!

Doesn't matter, since it's linear.

Ahh, makes sense. I will put the 0.00v and 4.99v info points in then. Thanks for your help.

Does your glowshift guage AFR readings match what it says in tunerstudio. I have same setup and my AFRs are reading different.

I am still buttoning up the car. This is a new engine combo with turbo's and ms3x. I am waiting on a few parts to finish it all up, but at that point I will know if the AFR's match.
Sorry I couldn't help you now. But I think you can adjust the wideband calibration in tunerstudio to get them to match each other. But i'll let the pro's here confirm that.

You have to manually calibrate it and change the default values a bit to get it to match. The grounding offset is why they do not match perfectly.

Ok thanks gonna start messing with things. Appreciate the help guys.

Boostaholic how did this go for you? Was everything matching up between gauge and megasquirt? I'm about to install mine today with the same setup.
