Default ECU question. Ecutek vs UTEK?

I'm trying to compare the Utek vs the Ecutek reflash that shiv does.

I like this aspect of the UTEK from turboxs website and wanted to make sure that the reflash from vishnu will do the same things..

from turboxs
UTEC enables complete programmable control over ignition timing, fuel, and boost, while allowing the factory ECU to maintain control over tedious and mundane functions that make the car drivable on a daily basis._ Functions like cold start, hot start, intake temperature compensation, AC compensation and closed loop fuel control signals are all managed by the factory ECU reducing your tuning time significantly while enhancing daily drivability._ Spend your tuning time doing what we all like to do making your WRX faster!



sorry if this is a basic question I can't find much info from vishnu's site and know there are alot of really smart people on here!
THANKS!

The Utec (not Utek) only alters the signals that the factory ECU sees. ECUtek remaps the factory ECU with new values (fuel, timing, boost).

They are different means to the same end. I prefer ECUtek, but that is because I don't have to change my maps anymore since I like the power I have. Tsis is the main benefit to the Utec. You can change your maps along your upgrade path to make the most of your mods.

ECUTek keeps all the factory controls in tact. In fact all ECUTeck does is change the factory maps so that it runs the AFR and advance that you need for your mods. ECUTeck does not add anything to interfere w/ the operation of the ECU, so the ECU runs the same as stock, just w/ different maps.

Ok so with the ecutek I need to have someone that knows what they're doing remap it, and with a Utec I can mess it up myself.. thanks for the clarification I definitely understand it better now.

Just don't assume someone knows what they're doing just because they purchased ECUTek's DeltaECU tuning product :-)

haha thanks, I'm getting tuned by shiv, and from what i hear he knows a thing or 2 about these cars. im just thinking farther along when i do a turbo if hes not coming back for a while I'd have someone modify it slightly.

.
The UTEC does not alter any signals related to boost or timing to trick the stock ECU. The UTEC offers full standalone timing and boost control, and soon will stop using piggyback fuel control.

Yeah sorry 'bout that. It only modifies the MAF right?

The only signal manipulation of the current UTEC is for the MAF sensor. In the near future the UTEC will handle the fueling directly.

Sweet. That will definately be a great feature. The best of both the piggyback and standalone worlds.

Utec is great if you will be making changes to your car over time. it's cheaper in the long run than getting reflashed.

Ecutek is great for set it and forget it. You put everything into the engine then get it tuned and dont touch it again.

Either way, as long as you get a good tuner to work on the car, you'll be happy.

will current UTEC users be able to flash the firmware to get this feature as in the past?

Just to let you know there are many companys that say they tune EcuTek's. There are definitely recommended shops as suggested by many people on the boards.

I would do some research on who are recommended tuners and who is not. there are definitely well know tuners that do good work, such as Vishnu, Cobb or I-Speed USA.

Yeah I had to get my 2 cents in,

Every UTEC we've ever sold will be able to get the free firmware update that will enable this feature.

Nathan,

When is the expected release date of the new ECU. From the sounds like it, it will be a pretty good unit.

Cheers,

Bill the new firmware is in beta testing now. I hope to have a preliminary version of this software out sometime in the next two weeks, but obviously it has to pass the beta test first.

elsanto don't forget about Cobb's AccessECU or AccessPort. You do the flashing yourself with their maps, and if you have to go back to stock, you do it yourself. Eventually they will have a tuning setup available which will give you full control of the ECU.

Used UTECs = HIGH resale value

Used AccessPORT = HIGH resale value (ok i know they aren't out yet but I'm smart and I know these things)

Used custom ECUTek ECU = hard to sell and low resale value.
