Longtubes going on today...tuning question

[larr12]

Placebo. You can also see yourself that it’s looking great in the logs before hand.

Ok. Thanks for your input.

And where's your insight ? Your just repeating what you hear from some tooners.


Exactly.

My 2018 Gen3 A10 non drag mode was already tuned by Trevor from PBD [E85 and 93] before I added LT's , sent him a data log and he sed they looked good and all he did was turn the CEL off.



I installed used MBRP LT's and connected them to the 3" Outlaw catback I already had, After adding the Helmholtz pipe to kill the drone and adding a Vibrant mid resonator I finally got the nice deep drone free sound as close to a 2V I've ever heard from a 'Yote.

Never dyno'd with LT's but it made 465rwhp/420rwtq with cats and E85, trapped 122 on the 1/4, Trapped 124 after the LT's.

Careful now, you'll upset the know-it-alls.

But... but...but... You said that once you had a tune, the "logic" was already there for long tubes???? What happened with that statement? He shouldn't have needed a retune, right?

According to the major tuners, you don't "need" a retune for adding long tube headers. Never once did I say you need a retune for headers. Is it wrong to do a data log and have it checked after you add something like headers?

Oh, got it. You were referring to yourself with the "upset the know-it-alls" comment. Makes perfect sense now. Thanks for the clarification. Sorry to rattle your cage over nothing.

Okay clown.

SO...I know this thread got a little heated. Headers and corsas are now on and what an insane sound this thing makes now. The car is not fully tuned, although the shop I brought it to did do something as there are no codes popping up or CEL. I will say something worrying did happen, however, after a pull to about 6k the engine turned off and the car went into accessory mode. I also have been smelling a sweet scent that I initially thought could be coolant but after further research I assume is just fresh pipes.

After the accessory mode incident, the car turned back on without a hitch and ran fine with no CEL or codes. It didn't happen again for the rest of the night, although I was nervous to fully rev it out. Called the shop this morning and they said it was strange but that's it. The car will be going in for a full dyno tune whenever they have an opening.

Has anyone else experienced this or had a sweet scent after new headers install?

No scent, but it initially took 3 days before I got the CEL for the first time. Give it a week and drive it every day, if the cell doesn't come on by then you should be ok.

Okay clown.

Great rebuttal ! ← sarcasm

 

[larr12]

@degajake glad to hear everything went perfect. Yes, I agree, the sound after the headers is beautiful. The CEL on my car went on after 100-125 miles. Did a few data logs, my tuner sent me a revision and its been perfect.

Send us a sound clip to hear that combination.

I'm getting long tubes installed next week on mine. Then 3 or 4 months later I'm having a blower put on. The shop told me there is no point in doing a tune if I'm going to add a blower in 3 or 4 months. Just the headers will free up 15-20 HP without a tune, and there is no chance of damaging the motor. There is no point in me paying a tune with just long tubes, when I'll need to retune the car again 3 or 4 months later for a supercharger.

I was told the main risk of running long tubes with no tune is the CEL will stay on. So if a completely separate issue pops up that would normally throw up the CEL, I wouldn't know it, because the CEL will already be on from the O2 sensor.

If there is a way to damage the engine by having long tubes with no tune, please let all the performance shops in America know, because they don't seem to have that information.

I agree, get it tuned once you get the blower on it.

We did essentially the same thing. We had our headers installed by an Optima Battery series champion. He told me that running without the tune and LTH would not have adverse effects. Once we data logged VMP sent the revisions, he/we installed the tune. I do get the pesky O2 codes referenced above after about 100 miles or so.

Enjoy!!!
