Engine Management question

Is there any purpose to use engine management with the following mods:

1. Green drop-in air filter

2. TBE


Basically, what i am saying is............would there be any reason to tune fuel maps or boost maps (or any other item that can be tuned) with those mods?

Wouldn't you need other significant mods (i.e. bigger turbo, fuel pump, etc.) before you could actually use engine management to create more power?

Thanks in advance

I would help, but it all depends on what you are willing to spend.

A good tune on an otherwise stock car will gain 10-15 hp. On your car, I'd say you would see more than that. Engine management is the single best mod you can make on any car, no matter how many mods.

I prefer the UTEC (although I'm about to get rid of mine in favor of a stand-alone). You don't really need the fuel pump and injectors with the stock turbo.

A good dyno tune will be the best thing you can do for your car.

I agree with Cosmo, the only thing I would do before tuning your ecu is the up-pipe. I have the Ecutek and I am very happy with it, so if you don't plan on doing alot more mods right away that would be a good way to go also and more power is always a good thing!

Whats the difference/advantages of switching to stand alone instead of the UTEC? Would that be for when your done adding mods?

Thanks,
Mark

No the standalone has more potential. The UTEC has limits because it can only control fuel, timing and boost. A standalone controls everything, but is much more complicated than the UTEC.

IBAUCLAPlaya, don't you have the Cobb AccessPort and how's it working for you? Anyone know anything about the AP for the '05's?

Yup I got the AP and love it. I had the UTEC but it didn't work for me. The complaint about the AP is the limited number of maps. It would be nice if they had a map for the VF34 with an IC too, and some stuff between stage 2 and 2.5. But I love the gains I had, and I especially love the STX legal map

What else does the average person need to control?

And, it controls more than that....

I hear the UTEC doesn't work well w/ injectors about 700 cc. I don't know what else but I just hear once you start getting BIG power, you need a standalone becasue the UTEC isn't giving the maximum potential.
