Just got my Ecutek on my stock WRX and it runs really really good. It seems like the car is much smoother than stock. Plus, you get more power. One thing I notice is that the boost is better manage. Before, it would just jumps to 6-7psi at partial throttle or WOT around 14.0 psi.

5th gear, feels like 4th gear. 4th gear feels like 3rd gear........
To me, the car pulls so much stronger than stock.


Thank you Shiv, Brett and Ken at Vishnu for your help.

BTW: Shiv, thanks for the drivng lesson in the rain today. :)

I had a question on the Ecutek. Did you need to do any tuning at all or was it that the Ecutek was installed and you were done?

Tuning MUST happen to make any map. You then load the MAP into the ECU of your choice.
The question I think you are asking is, "was your car tuned or did you just get a flash (premade MAP)."

christoph1371,

Yes, that's my question.

Maps need to b made since all WRXs aren't created equal, right?

-Buzz

Buzzman, I had my car on the dyno to get the reflash. Remember, you do not have to get your car dyno to get the Ecutek reflash for a stock car. From my understanding that the generic map, works very well and safe. I think the advantage of getting it tuned is that you get a alittle more HP. I believe that the new stage sub-zero is plug and play. Very nice.

Hope that helps.

Just to muddle your minds more... Dyno tuning is a great way to determine how well your car runs... on a dyno. On the street, it's always another story.
Don't always believe that because your car was tuned on a dyno that it will be the cats' meow. It can be a great map, but not always.
I have always believed that the car should be tuned to your driving style. So if you just like spirited driving around town or you had a weekend track car (both cars with same setup) then the map would be different for both setups.

christoph1371, good point. I agree.

Hman,

Do u know if the install is easy and could b done by myself? I heard that the install is something like $300

Install for the ECUtek?

yeah

There is no install for an ECUtek. It is an ECU reflash. Pretty much a vendor, like us i-speedusa.com, plugs into your OBII port, links up to your computer and loads a map into your car. Of course tuning will have to occur to refine a map for your cars' ECU.

An initial Flash is between $950 and $750. That fee is set by ECUtek UK. That first time fee registers your ECU as an ECUtek flashed ECU. After your flash and IF you decide to get new modifications, you can go to ANY ECUtek vendor and have them reflash your ECU. There is no set fee for what ECUtek vendors can charge you for your 2nd, 3rd, 4th etc... fee.

If you want to see it or get a ride in a car that has a reflashed ECU then you can swing by our place this saturday. We are having an install session all day.

To my understanding there are two ways you can do it:

1. If you live near Vishnu, you can make an appointment to drop off your car. You do not have to do anything related to install for the reflash. They will not need to take your ecu out.

2. You can take out your ecu and mail it to them. In return, they will mail you back the same ecu with the new reflash. If you do not want any down time, they can mail you a core to use while waiting for your ecu to come back.

Taking out the ecu is fairly easy. It takes some people less than 10min. to remove the ecu.


Cheers.

hman,

Both of those statements are true and I am sure other companies will be doing the same thing.

Hi guys,

Here's my 2c on dyno tuning. Conducted properly, it provides an excellent platform for proper ecu mapping. With it, the tuner can isolate and adjust for trouble spots. He can also find areas of over-advance (which causes unnecessary engine stress) which would be impossible to determine through street tuning alone. He can also develop the safest-possible fuel curve by running richer until the point of torque loss (same applies to ignition tuning, of course). And more. These basic tuning techniques are simply not possible through street tuning alone.

Of course, street tuning should be a part of any tuning process-- after dyno tuning, of course. Without it, transient over-boosts, lean-run, etc,. can go unnoticed. But as for making power through preliminary mapping, the properly-conducted dyno tuning is, by far, the best tool for the job. When trying to extract 150-200hp/liter, dyno tuning is the only safe way to derive proper ECU mapping.

Just my 2c,
