Also, anybody want to loan me their wideband? 
Maybe I need to do more research. I thought you loaded the software to a computer and mapped it from there. Then the wideband plugged into the truck and you monitor and make adjustments from there to the desired settings.I've read better performance and mpg's with a properly tuned unit... so that's how I voted.
Don't you need a welded-in 02 sensor bung-hole to insert the wideband probe? :lol:
Use the money instead toward the cost of some alloy's. In theory, that should better your mpg's a bit.
Yeah Ryan, something like that... My understanding is a scan tool is needed to check if its in Open or Closed Loop, and what the fuel trims are. The fuel trims are what gets adjusted in Closed Loop. The wideband is used for programming ideal Open Loop (full throttle) AFR by adjusting the MAF sensor signals to the ECU. That's my understanding at least, I'm sure there's a lot more to it. Sorry bro, I'm not much help here. Sometime down the road perhaps...Maybe I need to do more research. I thought you loaded the software to a computer and mapped it from there. Then the wideband plugged into the truck and you monitor and make adjustments from there to the desired settings.
Aftermarket electronics are a mystery to me lol I'm still trying to learn all these things. Help me Ryan! haha Am I totally clueless? I think I am now.
