In the market for a new EM...i see people making big power with Hydra(is this sti only)out of my price range anyway
i have a wrx
I see some good numbers with AEM, but not usualy every day driven cars..
what about UTEC..can it be tuned and power worthy with big turbos..like gt35r, 40r, with worked blocks??

Consider this- BV's 9.67 STi is using a UTEC.

I think it will be plenty for whatever you're going to be doing.

I'm pretty sure they switched to the Hydra...

I drive my AEM every day, My personal opinion is that it is by far the most tuneable standalone available for the wrx. I have seen a hydra being tuned, I didnt get to play with it myself. However I didnt care for the interface.

They did, but they were doing 10 second passes with the UTEC before switching.

If I remember correct they did 720whp with the UTEC, Gadiel once told me that were there might be a diference is at 30+psi with a GT35 or bigger turbo. So unless you are going to run in does parameters every day or every weekend I'll use the UTEC. Much more friendly!

i think utec is garbage. it has no way of learning outside temps and different weather. . blinking light everyday. i use my utec on my sti simply for a race map and then use the trouble free ecutek with a turboxs knocklite. cant go wront there. just make sure whom ever does the tunning is pretty good at it.

Remember that the UTEC its only as good as the tuner who set it up and obviosly UTEC its not the only ECU that is on the market. Depending on your need is it's the computer your going to use. I just think UTEC cover more needs than others.

are yo ulooking for a utec ? I have one i took off my 2002 wrx before i traded it for my 05 sti. I'll sell it cheap. I only used it for a month . still set up pre programmed from turbo xs

Are you talking about the knock light??? If so, and If you see it everyday, I think your tune is garbage not the utec.

The UTEC is *not* an ECU.

If your utec knocks everyday, get a new tuner, not a new em.

Big v made that 720whp on utec and made almost the same on the hydra. Many guys do not have good tuners and do not get the results that they are looking for. :eek:

It is with a Wideband 02 sensor. The UTEC is capable of doing anything with this add on.

However, the cost of a wideband 02 sensor and UTEC alone cost the same as a Hydra. If your power goals are that high and you don't have a EM yet, go Hydra. I don't know much about the AEM unit.

Well I have tuned Utec , Hydra, AEM , Cobb Accesports, Motec and others

I have to say that Utec is a good product but at this moment I like more others products.

If you want high horspower use a AEM or a Hydra.
The first thing that you want on a good ECU specially on a high horspower aplication is a reliable knock control.
Other thing are a good speed procesor, good resolution, and good dataloging.

If you use a good tuner is possible to reach good number with the UTEC but I think that you reach the same numbers and more safe with other ECU like Hydra and AEM.

I know that every body wants to know the diference between Hydra and Utec.
With both computer I reach similar horspower up to 700whp. I test both comp. at the dragstrip on a back to back pass on the Big Valley car and always the car run between .3 to .4 faster on the 1/4mile with the Hydra.
Why this happen? the answer is better resolution. With better resolution you refine more the power over the whole rpm range.

If you see my car I run 10.7@129mph with my STI . I run my car on boost only. I dont think that I could reach thats numbers with the Utec on my car. Thats the reason I switch to Hydra on my car.
If you are going to install a Gt35 or Gt40 and build block on a Subaru use Hydra or AEM and dont look back.

If you have more question send me a PM.

..yeah.......really.....bad juju if it blinks all the time....sniff----poor motor dying a blink at a time.....sniff :(

Also v5 of the firmware has temp compensation for timing and fuel...blinking CEL = knock.

utec=maf :(
stand-alone=map :banana:

which equals more money and having to convert it over to map...right??
now im considering a hydra but i also need a map sensor and a wideband(whichever route i go)

The hydra include the Map sensor. And the wide band you can ask the tune or the dyno to bring the wide band for the tunning session.

By the way the Utec use the MAF but also use the stock Map sensor.

Or just put your utec over an Ecutek tune.....tis fun!!!

this is very powerful.

yeah...i love it.
safety and ecu learning with some more crazy map tuning on top of it!!!

Can you tunne the utec to eliminate the oem maf.

Or put it on top of a free ECU reflash using the tools out there. Just as powerful.

Can you tunne the utec to eliminate the oem maf.

Not officially. Anything is possible but the likelyhood of it working well is not so much. EVO UTECs are starting to do MAP and not using the OEM MAF, if I recall correctly, so it might be in the future we see this for the Subarus.

How you get a free reflash?

well if you added a temp sensor it might be alot easier because the MAF is a temp sensor as well as a meter

Good forum. what tools are you using.

I haven't tried any map editors made yet.

Let me know if you do it I'm a little bit comfuse with that forum, don't know how it work.
