Because $2k is alot of cheddar. I know quite a few people that have both and it works great, but it doesn't really seem worth an extra grand.

What top speed problem are you talking about?

hey t-kid,

they use both mostly when they're using bigger than STI injectors.

Since thoses PE are a little slower than the stock injectors, they're a little harder to tune with a utec, Reflashing the stock ECU is the easiest way out of this problem.( but $$)

my 2 cents

I am a faithful and loyal TXS users.

I used the Ecutek to do a few things.

A: get rid of the 4EAT speed limiter
B: raise the redline on the motor to 7500
C: scale for the 785CC injectors I run
D: adjust the parameters for the catalyst tests
E: adjust the closed loop cross over conditions for more spirited driving.
F: setup a more appropriate timing curve and fuel map designed for the mods I have in case of a UTEC failure.
G: adjust the learning parameters of the ECU to learn hard and fast after an ECU reset.

My UTEC:

A: runs my water injection system
B: allows for more robust fine tuning then ECUTEK's user tune features
C: has an 87 octane, 93 octane, 100 octane maps on it.

It's worth the $$$ if you really maximize the merits of both. Cause in the end, it's still less then a full blown EMS with a LOOOOOT less headache!

If you could self-tune with Ecutek, I don't think anybody would keep their Utec's around...

Hmm...not too sure about this..the ability to tune is just one of the many great feature of the UTEC.

The way I see it, it's the other way around...If the utec could manipulate some base parameters in the ECU, nobody would have a UTEC with an ECUTEK

As Rift does, Adam and I both (locally here in Portland) run STI RA V7 ECUs with UTECs on top. I have the EcuTek flash software, and I still run the UTEC on top. Why?

(1) The EcuTek flash is mandatory for running these large setups, especially if you want to have the car really drivable. Like Jorge said, speed limit removed, scaled for injectors, scaled for BIGMaf, scaled timing, change to MAF response curve, change to injector comp for slower PE injectors, change to open-loop/closed-loop parementers, etc.

(2) The UTEC on top gives easy to adjust on the road fine tune, including mapswitch. I use the UTEC for my C16 map (lots more timing, leaner mixter), as well as flat-foot shifting and launch control (worth the price alone btw). As well, it can drive WI or Nos.

Of course 2k of engine management seems expensive, but you really can't spend enough on management. That is the glue that makes all of your mods work.

When running ECUtek and Utec... are you guys leaving timing control completely up to the ECU (on pump gas setup)?

So is the ECUtek tuned for 93 octane and the UTEC is left at 0's all the way accross the board. I'm really confused to how this works altough I do want to do both.

In my case on engine 3, the UTEC was MANDATORY!

it was such a noisy motor I HAD to hardcode a timing map, something that CAN be done with an ECUTEK, but is so much simpler with the UTEC.

Typically, I run an AFR for the average gas I want to run, and hard code that into the ECUTEK, same with an ideal timing curve, and ignition correction map. In a perfect world, all I need to do is leave the UTEC fuel maps at zero.

Now, with the engine 4, I'll be relying on the ECUTEK to typically handle all my 93 octane issues. With the UTEC handling extended knock control outside of the my defined ignition correction and knock correction parameters (maps in the Flash2k2 software).

The ECUTEK tune will be conservative! Then, from there, I can use the UTEC to do boost, timing, fuel tweaks for a variety of fuel.

The ecutek itself (when provisioned in the ignition correction maps), can downgrade itself for different fuels. So I'll go conservative on the 93 octane tune, leaving me room for anywhere from 89 to 94 octane. The UTEC will be handling 99+ octane stuff.

That's how I use both in the real world.

As I see it, it really comes down to what you want to be able to do?

1.) Do you want to play around with tuning, have different map settings for different occasions, different kinds of controls.
2.) Do you want a reliabel daily driver you can drive anywhere in the country and never have to worry about anything ever, just fill up and go?

Some people prefer to control there power some more and have fun with there car. UTEC is a great setup then.

Though all our customers prefer to not have to worry about that. We give them the limit of what mods they have in the car with the EcuTeK on 91 octane, though once in a while we tune a car with 100 only. Those guys just want a track car day in and day out.

It comes down to what you want. Anything is possible with both setups, you choose what you want.
