Need help here.
I bought PLX SM-AFR

I don't have the Pro version of HP tuners and honestly i don't want to buy it!
I did search but have not found anything pertaining to our TBSS's. Both here and google.

I know there is a way to hook up the wideband to read off of the EGR sensors/wires. Even to hook up threw the A/C pressure switch.

Has anybody done this?

How are y'all logging AFR if you don't have Pro version of HP tuners

Thanks in advance

There are ways but the people who know what they are doing use a interface that accepts 0-5v inputs. I wouldn't skimp when It comes to getting lambda/AFR dialed correctly with a known voltage offset.
So true... First person that tuned my truck "did" this he claims... Truck wouldnt go over 80 end of story... Had to get it tuned elsewhere and wideband hooked up.

You should be able to do it with the ac pressure sensor and just not use it while you are logging. There is a chance you could get it to work on the map sensor 2 or 3 input also on 07+ tbss
