Iv got a 2014 zforce 800ex and got a magnum tuner for it but the diagram and instructions ain't clear. Does anyone know which wires are the signal wires on the o2 and iat sensors? 

Service manuals are out there. I do have one for the z6. I tried to upload it but no joy. For the z6 it is O2 ecu pin 24 O/W wire. For IAT it is pin 6 Y/GR. Hard to see second color but yellow for sure. Let us know how the tuner works out. I did look into one of these but seen it as a gamble. When I changed my plug, it showed I am running a bit lean.

I was thinking about getting on of these because they're cheaper and some don't require programing or adjusting. Did you get yours hooked up? How well does it work?

I never could get it figured out spent all kinds of time researching and emailing the company but no one could answer my ?  Ended up going with the ejk and  glade I did its worth the fifty extra bucks

OK. Thanks.
