some of my parameter never change.

For instance my baro always stays a 99.1 and my FAR stays at .07 on the trinity itself and on the data viewer it stay at 14.37

not sure what the "baro" is you're talking about...

but the AFR will always be 14.xx at normal part-throttle driving.... it will only change when you go WOT...

Baro is the barometric pressure. What vehicle do you have? Do you know if that is even used for your vehicle? That probably won't change a whole lot.

You are looking at commanded Fuel/Air ratio, not actual.

I have a 2005 srt 4 neon. I'm trying to use my fuel/air to make sure I'm not running lean. And also how do u change tire size to fix speedo

You need a wideband to monitor the air/fuel ratio, you can't use commanded.

You can't change tire size in the SRT-4, you have to change the gear in the transmission.

Oh, these use a mechanical speedo?

I was wondering why we did not do tire size....makes sense.

Oh ok makes sense. Duh. Thanks for the help
