Hi All, If you have a Tec3 or Tec3R with WinTEC4 4.8.20 and a wideband controller please chime in.

I'm having a problem where EGOv is intermittently showing 0v which causes AAFR to stick at 9.98. I'd like to see if I'm truly the only one with the problem.

Thanks in advance.

Im having the same issue after being stuck at 9.98 I tried to uninstall then reinstall wide band now it will not pick it up at all.Have not messes with for a while I just put in my other tec3(wintec 3.56).

Maybe Try upgrading to to to 4.8.25 see if it helps

Tec3 on Wintec4 and an Inovate wideband. No problems whatsoever.

Just to be clear, you are using A/D4 for the WB input, correct?

So we are all on the same page, A/D4 = G19 = WinTEC4 GPIO#8

It's weird that both our units went 9.98 afr.Then mine went off completly. I can not remeber but I think mine showed the voltage of the input but would not show afr.
It's been a while since I messed with it.

If you feel like messing with it let me know. It would be helpful to compare notes. I'm guessing it would also help Uwe and EMI track this issue down.

That's where it is with my unconverted Tec3 with WinTec3.5.6 (if I remember the version number correctly), and when I converted to WinTec4, I didn't change it and I can't even find a A/D4 in WinTec4. The GPIO selections only go up to 3! I looked around the software and maybe somebody can enlighten me please. I searched the Wintec4 help files and nothing. So right now I don't know where in the software it setup

This might be a clue guys - the way JimK describes it is the way it should work if you are using A/D4 as the EGO input. In other words, if you are using A/D4 for EGO it is not available for other uses.

John - do you see this behavior in your software too, or is A/D4 available for GPIO programming?

In WinTEC4, if I select "Use WIDEBAND EGO" in the EGO calibration screen, Input 4 aka G19 is removed from the General Purpose Input/Output screen. if I select "Use STANDARD EGO" in the EGO calibration screen Input 4 is present. Below is a screen capture of the GPIO screen when STANDARD EGO is selected. It does not appear as though there is any difference from WinTec3. Still four outputs and four inputs that are not interchangeable.

card counter, Just curious, what type of laptop/PC did you use with the WinTEC4 when the AFR went to 9.98? (CPU, memory, OS, serial port or USB)

I'm using a AEM UEGO on an updated purple box and haven't had a problem yet.

I have a TEC3 and using 3.56 with an FJO Wideband. The sensor ground was not reading the same voltage as the TEC unit so I had to use a conversion table. I then inputted the correct settings and it still did not work. (this was a while back)

I called Russ Turner and he told me that the first number in the conversion table had to be more than a 9 so I used 10.01 and it worked fine after that.

Not sure if this is related to your issue but I figured I would throw it out there.

card counter,
Just sent you a PM
