Going to be buying a WRX soon, and heard that a Reflash of the ECU is absoutley necessary, Not really looking for horsepower gains just some honest advice.

Thanks

it is necessary because it helps the car run much better and adapt to our local piss gas. It helps the car out alot and at the same time help with gas and the overall performance of the vehicle

I say this because i know you will be hitting the X very hard very often and i prefer saving the engine as oppose to breaking it

There are guys doing opensource. lot cheaper but you would not get the guarentee of ECUTEK.lol

you could also DIY buy a cable get a map from someone who tuned their car and flash it to yours. Would work out a lot cheaper. The cables cost about US$90

trinidad has no proper tuner for opensource

which one of those have you tried has the better tuning?

Knight1 · Posted: Tue May 06, 2008 9:33 am Post subject:

^^I can't really compare them 1 on 1, as both were done slightly different setups, and at different boost levels.

What I can say though, is that relative to the starting point for each method of tune, both provided noticeable power gains (via "butt dyno" Laughing

) and on real dyno numbers as well.

Knight1 is giving good advice there. Opensourse is not witchcraft as some people would like to suggest. Its a matter of eliminating knock to save the engine and then adding some power once you get in that safe zone.

Ecutec uses the same method of tuning as opensource all and except that they added some additional coding to make tuning easier for the agent. They also back their stuff and provide a lot of R&D so as not to have customer failures. Remember ecutek broke engine after engine in their labs to get a perfect map. Local tuners dont have such a facility.

Suby (member since 4 May 2008 ) seems to have a bias or a strong position against opensourse. To start with there is no such thing as a opensourse tuner. You have tuners, fullstop. Some tuners can only use opensourse some can tune on many other platforms and opensourse. All tuning is the same, manipulation of fire, air and fuel.

Opensourse tuning doesnt break engines. Subarus are very prone to two things. One is spun bearings due to lack of proper servicing (bad oil) and the other is broken pistons. The latter a direct result of a bad AFR mixture or very high compression vs igntion.

So to agree with knight1, look around talk to people who have results. Right here, Scoobytnt.com, or Subytuners.com you would find articles on opensourse. To tell you the truth if you can afford it go ECUTEK. If you looking for safe tune or willing to learn how to tune your car yourself examine opensourse.

BTW you also have other aftermarket options, such as Hydra, AEM etc.

Go Fast, suby is STI. He has been trying to start flamewars on all the sites. He thinks as he as an ecutek forester he has the fastest car in Trinidad. Lol.

Dont take him on, he knows nothing.

ECUTEK is a company that reflashes ECUs. They added extra logic to the ECU programming buts its the same thing.

OPENSOURSE is just a process of copying the ECU maps to a PC, changing values and copying it back the ECU. Same process of ECUTEK but no extra logic added.

The extra logic I refer to gives some limited live tuning, boost switching and Launch Control.

Opensourse only has limited live tuning and launch control now. Boost switching underdevelopment.

ECUTEK comes with some guareentee that engine would not fail because of the tune. Engine failures have happened in Trinidad on ECUTEK cars but causes are not related.

Other Opensourse tuning does not have the guareentee.

ECUTEK would not push the limit of the engine performance parameters.

Opensourse may (depends on tuner)

ECUTEK (T&T) limited to 1 agent so far

Opensourse many tuners available, guys who making good power (more than ecutek) without failures.
