hi im a new evo owner bought a 14 evolution and i love it better then my subarus but was wondering how do evos work tuning wise because for the subaru you had to tune for everything.


for evo i know you need to retune for a full exhaust from the turbo back. but what about

intercooler piping? can i do one pipe at a time ? or should i do both at once ? what happens if i did one at a time?

what tuning method do you suggest cobb ap or open source. whats better ?

do you need to retune for an intake ?

 

Bump

 

I'm a noob as well (have mine for less than a month) so sorry I can't answer all your questions:

You should specify if you have a GSR or MR because if you have an MR you'd pretty much disqualify the Cobb AP.

Retuning for an Intake: Yes.

In general most of the time you'll be retuning for each change. So just grab a bunch of things and do it at once then tune.

CBE is an exception though.

 

I pretty much get tuned for anything that really affects air flow and fuel. Some intakes you do not need a tune, for intercooler piping I would recommend getting a tune as well.

As for tuning methods, do not use Cobb OTS maps if youre planning on buying a accessport!! the AP is pretty much a waste of money for our cars unless you like switching between multiple maps. Open source tune FTW!

 

our cars run rich, so most mods are okay without a tune, though you won't be able to exploit their potential. if you are concerned about the stock tune as you modify, get a wideband sensor/display and keep an eye on it. you will need one if tuning, anyway. they are a really, really good gauge to have as they are a great indicator of when something isn't right.

EcuFlash is much (x1,000,000) better than COBB. there are waaaaaaaaaay more options within the software. either will cost the same to tune, so may as well go with the better product. plus, i think a Tactrix cable (what you use to log/tune) is cheaper than the AP. if you take your car to a tuner, then you won't even need to worry about that; all you will need is a wideband (unless your tuner uses his own @ the tail pipe).

 

I'm not an expert but. New parts like intercooler, exhaust and piping then you should get a tune. I bought my car with TB exhaust, intake, and a cobb tune. While i may stick with cobb on the mild tunes, i plan to go open source once i get deeper in. My plan is also to collect more parts and install at once and get a protune. You'll spend $400+ on a protune so you should just install all at once then do it. Otherwise it will be a waste. Also, some intakes require tunes, some don't, to greater benefit from the intake get a tune otherwise it's for looks and sounds.

 

What's a "pro tune"?

 

Make sure to check out our site: http://www.extremeturbosystems.com

You don't need a tune with our

ETS Intercooler
ETS Intake
ETS Intercooler Piping Kit
ETS Catback

I do recommend a tune with

Downpipe
Test Pipe or High Flow Cat

You definitely net more horsepower and torque with a pro tune. Cobb has made it pretty easy to run their maps with our intake and modifications.

Hope this helps!

I will take a wild stab at it- a tune done by a professional

 

I'd assume so. Now that you day that, I think I have heard the term before. I just call it "tune".

 

Yeah I would say like others did, with downpipe and test pipe/high flow cat you would look at tuning. I did full bolt ons all at once to just eliminate any concerns
