HPTuners/FAST Wideband integration?
HPTuners/FAST Wideband integration? Has anyone integrated their FAST wideband into their HPTuners? I have been doing some readin on this but I am confused. The part I am confused about is the values that I should enter into both. The FAST documentation says that its range is 0-4.096. On HPTuners website, I see where the example uses 10 min afr and 18 max afr. What are the reasons these numbers are chosen?
I used this guy's equation when I had an issue with my LM1, and only had access to a FAST wideband. Worked perfectly for me.

OKay, I got the histogram and the custom PID programmed. When I scan the car and look at the histogram that I created, I just get 0.00 in a yellow box. This value never changes. What could be my problem? I went into the FAST and set it up as the highres setting which I think is right. Even when I look at my charts view in the HPTuners scanner I don't get a readout. Any suggestions??
Okay I just made some progress. I realized that I hadn't inserted the PID into the table and that is why my histogram was not working. But now I have another question. In HPTuners I am getting a reading of like 9.72 for example and on the FAST dislpay I am getting a reading of like 14.xx. What would be the cause of this? Is that a part of the AFR correction I have read about?

Okay, now the HPTuners is logging an AFR a little closer to the FAST controller. Now it is like the FAST will read 14.0-16 and the HPTuners will read an AFR of like 12.8-13 something. I know this has to do with the voltage offset but I need to know the best way to get that reading. I need to make sure that 20.986 AFR is actually a 4.096 voltage output reading. I have tried connecting the multimeter to it but the wideband jumps around so much that I can't see what the voltage is at a specific AFR reading.
