    I have an ultragauge and so far so good. I purchased it because of a check engine light. I am thinking it is an o2 sensor. I'm kinda thinking I have a bad cat as well. I get an occasional p0430 code. I'm i jumping the gun by thinking it is a bad cat?

    Here is the reading from the ultragauge.

    LED conversion on every accessible bulb, TRD exhaust (dealership threw in for free along with the Blu-Logic).
    At normal cruising my truck with DTLT and URD Y-Pipe sounds vicious. At WOT watch out, super RICE sounding! I don't mind because I don't drive around all the time at WOT. It does have a similar rumble to a V8 Tundra that has an aftermarket CATback exhaust.

    edit*
    I have noticed a MPG increase already even though the ECU has not settled in after having the battery disco. My Torque app shows I am running super rich, up to 18:1 but at WOT it only drops to 12:1. I think after the ECU settles I will have a ratio closer to 14:1 at normal cruising.

    Thats LEAN

    rich is 10:1


    Idle or cruising, ur trucks gunna do its best to be around 14.7:1

    closed loop, I still hover around 14.7-15ish....................... WOT I usually dip down into the 10:1 area

    this is using a wideband AEM......... what are u using?

    10.1 is too rich that can be very bad for your engine

    The member I quoted was confused on how afr worked since he assumed that 18:1 was rich.

    Just wanted him to know Thats lean and that he may have confused the reading.

    U can watch trims with it..... At least Thats what I remember from when I used to run one... I have the scangauge2 right now thats awaiting custom mounting and isn't hooked up to try.

    I do have an ultragauge MX thats awaiting proper configuration and still looking for a mounting solution.

    Another option I'm toying with is a Bluetooth obd2 dongle for my galaxy note 2.... Thats awaiting some (hopeful) firmware tweaking to set on/off options for permanent install.

    A right angle OBD2 Y adapter cable works great!

    Currently I'm using an AEM UEGO for my AFR plumbed into YPipe.

    The scangauge2 with an x-gauge typed in will do afr. Not sure how accurate it is and when you set your refresh rate to fast it does a pretty good job of not lagging behind to bad. I like watching it sometimes. I'm at 14.6 at idle and cruise and 17.9 under open loop coasting in gear, like down a hill. and 11 something under wot in higher rpm ranges.

    When you guys say WOT are you talking about actually having the pedal to the floor?

    On another note. I ordered urd headers and a DT ypipe. Headers shipped about a week after the scheduled ship date. I was not too sour over that but the DT ypipe that was placed in the same order was not shipped. I was told they will ship seperate. Also not too sour about that. Another week passes with no tracking number for the pipe so I message URD. They tell me the pipe is on back order and they are looking to get out back into production in 20 days!! Then they offer for me to upgrade to the URD pipe and I will have to cover the cost?!

    How about if this shit is on back order mark it on your website!!

    /end rant.
