2016 OVTune Tacoma 3.5L Manual Transmission / Engine ECU Reflash

@St.Germain and I have very similar exhausts,we both have the URD Y pipe cat delete, downstream from that we have different parts. No CEL from the cat delete Y pipe on mine.

 

Not to derail thread but we’re there noticeable gains with the y-pipe cat delete?

 

My butt dyno noticed an immediate difference,real world dyno...who knows I do know it seemed to lose some low end but increased top end power. It also increased drone immensely, I solved both problems by adding a 2 1/2" spiral louvered glasspack in front of the muffler. I have the Flowmaster American Thunder dual outlet system down stream of the Y pipe/ and glasspack.

 

Just butt dynos

 

My butt dyno is saying good things.

 

My butt dyno is saying good things aswell, but I doubt the Golf GTI I met earlier was happy about it.

 

Check out the URD Spec u thread. That is the way exhaust I have and it deletes the rear cats. I had no lights or codes come up after install. It has been on for over a year.

 

Looks good! Been planning for a couple months to buy the Spec-U exhaust once the snow melts and I can work on my truck again. Love that sound. Good ground clearance since the exhaust has the t-case re-route.

 

Yah. My only issues were the drone was a bit much at first so I welded in a resonator and the exit of the tailpipe reduces ground clearance quite a bit. I am trying to come up with a solution short of getting a different dump pipe.

 

That's interesting,you must have the first Gen system.The pipe from the drivers side crosses over in front of the transmission/xfer case cross member on mine.

 

Do you have the URD y-pipe or the URD Spec-U equal-length exhaust? They have different routing.

 

I just have the Y pipe/cat delete.

 

That is why. I have the full spec u system.

 

This may be a dumbass question, but as a dongle user is the registration step required??? Fought with my laptop across two nights just to get through step one......

 

Nope. Just download flash manager to get the new tunes and new version of pcm flash

 

Yeah.....I really hate computers. I argued with it for about 15 minutes. It would identify on the p5, but when I tried to find the downloaded tunes files they weren't there in the
indicated location. At that point the wind started blowing rain into the garage right where I was at, so I unhooked and retreated to the dry....

 

I feel ya man. I couldn't even get the new flash manager installed.

 

Just flashed my truck tonight as a first time user. No problems. The PDF installation instructions seemed accurate.

I'll give the 87 FOB tune a few days to settle in and give myself some time to adjust. The throttle is very responsive, maybe even twitchy now. My WRX was just the opposite -- stock, it had a big jump at tip-in, while the Taco stock throttle slope is almost flat.

 

You dont need to be connected to the internet to flash. Prep in the house, take it into the truck... I see no need for standing in the wet.

 

never had a code on mine either, and i did the exhaust in stages so stuff was changing every other week for about two months, never a code.
