xcal2 analog issue - just shows 0V RESOLVED!

Edit, resolved, my friend messed up making my connector

So I'm finally trying to set up datalogging for my wideband. I set the voltage out to 2.1V at 14.7:1 with a 0.75V/afr slope, with 0V below where it hits 0 and 5V above where it hits 5.

I have my 9pin mini-DIN cable all hooked up, and copied this diagram which Ryan posted on the SCT boards to get my voltage at analog 1.




Then I go into Livelink and set up the analog1 to be (1/0.75)*v+11.9

press the green button to datalog

"bluouououooop!" the xcal comes to life and starts datalogging. I also turned on ACT and ECT to make sure its logging correctly, which it is.


Analog 1 sits at 11.9


I checked my cable with a voltmeter, and I have anywhere from 1.9-4.9V as my wideband warms up and reads from 14.2-18.8. So there seems to be a problem either with my xcal or my pinout diagram...

any ideas?

I just did this a couple weeks ago and I had the problem that the mini din connector actually didn't go far enough into the xcal2 port. All I did was shave a little bit of extra plastic off the mini-din cable so it fits into the xcal port farther and it works perfectly.
If when you plug the cable into your xcal2 it feels a little loose this is most likely your problem as well.

Well, the plug itself was bottoming out not the plastic.

The problem was what I thought it was, one of the pins. I was using one of those solder-type connectors. My friend put it together. Apparently very poorly.

So the analog1 wire's pin wasnt getting pushed in.

Now i just have the pins bare with no connector, put them in the right holes, and it works! False alarm.
