Can't Open-air Cal my WBO2, Vs. 2.5
So, I'm putting in my WBO2 today, and I have everything up and working, and the thing won't calibrate. I'm following the manual availiable from FM's website.
Basically, here's what I did (twice).
Car is key-on, hook up laptop, load from ecu the map I'm using.
With sensor unplugged, check in Settings->sensor that the value in WEGO zero cal is between 125-130 (it is, 127).
And check that the AFR reads 14.7 (it does).
Plug in WBO2, verify it starts heating up (ouch!), and check to see that AFR changes slightly. Once stabalized change WEGO Grad Cal to make AFR 20.7.
That's where I get issues. Changing the Value under Grad Cal does nothing. Changing the zero cal I can get it to move. Also, it fluctuated before heating up a good bit, especially when you blew on it. Doesn't move around once heated up.
Any idea's? I'm going to go back and verify the wiring is right, but I'm pretty sure this isn't the issue. never know, however. Though, if it gets readings, and heats up, I don't see issues there.
Hoping not to blow my car up,
