Tunerstudio Erratic Afr reading
Hi everyone,
Just got my Ms Lab Ms3 Basic install in my car
One thing I notice that seems a little odd is my Afr gauge on the tunerstudio.
It jumps around even if the actual wideband gauge is showing steady 14.3-14.4
Did I set anything wrong on my megasquirt?
It doesn't happen when I had my adaptronic ecu install so I doubt it's the wideband.
By the way I am running the Innovate Mtx-l wideband and wired the yellow signal line directly to the db37 behind the ms3 basic unit.
Here is a video of it on youtube. Please help, thanks in advance!

Sorry forgot this is probably a plug and play setup. Ground the mtx as close to wherever the megasquirt is grounded as you can.
Yes calibrate afr table, choose custom linear wideband and and try these settings. Should get you within .1 or .2 of what the gauge reads
.22v = 7.35 and 5v = 22.4

the problem with using sensor ground for the mtx-l is that both the o2 sensor and its heater use the same ground wire. It should not be connected to sensor ground on the Megasquirt.
With widebands that have a separate ground for sensor and heater however, that is the way to do it.

Does this looks normal now? Sometime it drop down to 14.3range while the gauge is at 14.7-15 range,
Also one thing I've notice during startup is that the gauge in Tunerstudio is richer during warm up. After a while it will slowly catch up with my mtxl. Is it normal?
I feel like I should look into the setting in my mtxl hopefuly that would smooth out the aft output.
Thanks
