UCON Flex Advanced Engine Management System

So are all the bugs worked out finally? Or people still having issues?

 

Some have issues still. Mine seems pretty solid.

 

Some occasional random check engine lights, but they always go away. It works well enough.

 

Im still having issues unfortunately. Hope to have them ironed out eventually. If im unable to figure them out, ill be going to the trd tune

 

Pretty much how mine is.

 

I’m one of the lucky ones I guess. Roostfactor and I installed mine two or three months ago and I have not had one check engine light. Knocking on wood! I have all the possible mods except the 7th injector, however that is on my bench still in the URD box waiting to be installed. I did what Loginfailed did and took my TRD flashed ecu out and put in a stock ecu at the same time the UCON went in. I think that is the main reason I’ve been good. Truck runs hard and pulls all the way through.

 

When did you get the 7th?

 

About six or seven weeks ago, it’s collecting dust. I want it mainly for reliability, I just need to figure out when to do it. Also I wanted to run all ten plus mods you and I did at the same time to make sure everything is cool before adding anything else. I’m more excited about my Borla muffler experiment. I need to get up there so we can play again, which is too much fun.

 

Cool! There will be a significant amount of metal that needs to be removed from the injector adapter.

I'm curious how the Borla will sound as well.

Good times.

 

@5thGearPinned whats the Borla experiment? I have one on my Taco as well.

 

We are going to remove his

$125 Vibrant 1142 3" Ultra Quiet Resonator

Vibrant 1142 resonator and install a 16" Borla XR1 muffler before the Magnaflow 12579 muffler.

So he will have a high flow cat, Borla, then Magnaflow. All 3".

 

Please post up some sound clips when yall finish that up! Definitely interested in how it's gonna sound!

 

lol. thats pretty much EXACTLY what I have. I pulled my Vibrant.. and switched to the Borla and Magnaflow.. all 3".

 

Is your Magnaflow the one that splits into two pipes inside the back to one prior to exit?

How does it sound?
Nice and quiet?

 

ahh no. Mine is single center/single center.

its great. I spent a ton of time dialing in my exhaust. I've gone through so many setups over the years. this is by far the best I've found. no rasp, smooth, quiet, no drone in cab. My Blower is louder than anything else.

I'll see if I can find some clips.. or make one.

Its: URD equal lengths > 2.25 high clearance Y pipe with cats > 3" piping with Borla and Magnaflow > dumped over the axle/down

 

I may give this a whirl as well. Do you remember which Borla part number you used?

 

I'll poke around in my build for the info. it was a few years ago. I had the Vibrant resonator.. and it still had some rasp to it.. the Borla muffler got rid of all that.

 

If you cant find the number, maybe I can figure it out off of style and dimensions. Is it round or oval. Straight through orturbo style? Case length & width etc. Summit has a pretty good sorting system.

Got it this far:

40575 is the one @5thGearPinned got. Its 16" body.

 

So did you start with the URD Spec-U system? If so the muffler that came with it is the 12579 Magnaflow. It splits into two pipes internally but is still a single 3" in and single 3" out.
