Yup, tried it. Have to verify the injectors are off and 20+afr is hit, then push the button for 3 secs. After recalibration, my numbers are identical.

 

identical as in, no difference between calibration methods?

 

Ahh, identical as in, the numbers it reads after recalibrating it with the second method are the same as they were when I just did the free-air (not moving) calibration.

Also, before and after I'm seeing ~22.1afr during coast-down, not 20.7 as suggested above.

 

On coast-down, it's not AFR, it is % O2. It should be 20.9 or so....22.1 is too high.

Air is about 21% oxygen, so that is what you should be reading.

 

I know, it makes no sense!

 

22.1 is high? wow im getting 22.4 on coast-down

 

My LC-1 also tends to read about 14.5 on average. I've recalibrated about 10 times trying all the accepted methods several times, and each time, its 14.5 during closed loop.

So do all the ZT-2 users see 14.7 on average during cruise?

 

Ive noticed on coast my w/b goes to 20.9 on the xd16,but on my logs it reads up to 86.7.Is this dangerous or normal??It also blinks o2 for a second or two.Ive also read something on here about rescaling stock injectors to fix certain afr problems,ill find it and post the link.

 

Well, mine does. Some other ZT-2 users will have to chime in here.

 

That's because the LC-1/XD-16 is reading O2 % on decel. That's why it flashes O2 and 20.9. It's percent O2 at that point. You can see the little ligth on the XD-16 for AFR or O2 percent.

 

so if you guys are seeing 20.9% how come im getting 22.4?

 

14.7 here with my zeitronix. Of course it bounces north and south of that as well.

 

Yes, my ZT-2 sits at 14.7 at idle and cruise.

 

My LC-1 showed 14.7 to 14.9 usually at idle/cruise before changed the narrowband signal. My LM-1 showed 14.6/7 at cruise on 3 different cars so far. I haven't compared the LC-1 to the LM-1 ...

 

What did you change the afr signal to, and did the cruise afr follow like you'd expect?
