Cool Fundimental tuning question for TN

Why does everyone persist in doing cat back and intake work first?
There is so little power to be gained vs the cost.

For the same, or less money you could do some ECU tuning and have more mpg, more power and the ability to tune for anything else in the future.


I've just always been curious. I just ask for people to think before they state why.

Intake and exhaust upgrades open the door up for bigger power.

You can't have a turbo with 1.75" exhaust pipe.

i think for beginners it seems a more feasible task to do intake/exhaust. with sumtin like an ecu its not really a tangible thing, you know what i mean? i started with an intake cause its easy, and i was scared shitless by any other mod.

Just ordered my S-AFC II, it'll be my second 'go-fast' mod. In the least, I'm expecting it to be something to grow with my following mods.

I hope to have my catback/headers done shortly too.

What userlain said, and that most cars are too rich, simple mods usually help that, give better gas mileage, etc.
But I've never spent $1K on a polished fart can exhaust, or $250 for a section of tubing and a cone filter either, so maybe I don't apply to what you're thinking of.
Pretty much have to do it all to get decent power anyways, but some cars just need certain things more than others.

I focused on the following as a minimum before considering ECU tuning:

Intake & Exhaust
Headwork
Clutch & flywheel upgrade
Diff upgrade to LSD

Cool

But the question is why not do ECU tuning first, like many people from non Toyota back grounds have been doing the last few years.




For the cost, nothing else will give you as much power, stock exhaust and intake or not. It'll sure as hell do more than an intake and exhaust together, a flywheel, or a differential/LSD upgrade.

Won't outrun good headwork, but that's double the cost if you don't DIY to begin with.

n20 costs a bit more with larger gains... But no other cheap work can touch it as a group, or by itself.

Thats kinda stupid ( excuse me but I'm not trying to insult anyone) ... Thats like learning to pull of a dive before learning how to swim... Or tuning your car for a bigger turbo and big injectors while you still have stock injectors and still n/a ..

You have to get the basics done first before installing the big toys..

besides any modifications to the pumping mechanics of your motor would require re-programming of your ecu ...

By choice, I would much rather handle the hardware aspect before tuning the software (ECU) side as I learn about my car. With the cars that we have, it's only natural that most will look into the engine side first as part of the learning experience on how to make it stronger.

ECU tuning in my opinion is more of the "fine tuning" phase when compared to focusing on the "foundation" of your power; which is the engine itself. Yes, everyone has their own preference when it comes to how they want to work on their mods. Personally, my preference is to focus on my foundation and build a stronger engine first. Once you've made your foundation the way you want it to, then you can look into the fine tuning aspect.

Do most of you here tune ur car mostly for performance or Aesthetics ??
well, i reckon thats a bad question...tuning would usually indicate performance upgrades.

so then the questions is, performance or Aesthetics?

Performance, sure..i'd love to have a decently fast camry (for a camry anyways) , but i also want to have a car people look twice at and wonder what kind of car it is, or "IS THAT A CAMRY?!?" or as they gossip among thier friends "Do you remember that camry we saw, badass"
(no huge wings would be used at attention getters either!)

anyways, to your question....I just love the sound, thats why those were 2 of my first mods, not because they would possibly make my car any faster...i dont want people to think that i think my car is fast.

So what would be a great onboard ECU tuning tool?
Do you need a laptop connected and is there an autotune mode?
