After not hearing any updates on the Utec I emailed them about the Utec. They say it will be available 8 weeks from the time they're done testing it on their Evo. They say it looks like they'll be done with testing in about 2 weeks.
I guess it will be another good alternative for everyone. I think the price is about $995.
Just thought I'd give everyone an update on possible release

 

Cool. I look forward to selling the Evo Utec along with TXS's other great products !!

 

I am not 100% sure about the 10 week quote that you received, but I do know quite a bit about the EVO-UTEC. One of the nice things about the EVO-UTEC is that it should be released with the all features of a full standalone ECU. I am more then looking forward to saying goodbye to the days of piggyback engine management. The WRX UTEC currently only allows stand-alone ignition timing control, but will be updated to full stand-alone capabilities very soon.

The UTEC is on our EVO and working out quite well, but I want it to be a bit more “feature rich” when we make it available to you guys.

Since the UTEC has its own coil and injector drivers, we have quite a bit more flexibility over some of the other piggy back systems available on the market. You’ll still have a stock ECU in the car, so you’ll have the opportunity to cede control of any load site to the stock ECU if you so choose. This gives you the ability to have stock like fuel economy, idle quality, etc, without being limited by the abilities of the stock ECU when you are under load.

We are still working out the bugs, but encourage you to keep in contact with us to see how things are going on this project. If you guys get a chance, stop by the booth at sema and we can let you have a look at our EVO. If all goes as planned our UTEC, exhaust system, intercooler, and Garrett turbocharger upgrade kit should be on display.

For those that don't know. The Utec seems pretty similar to the Xede but it has more features for tuning. I'm pretty sure they use similar methods for fuel control which is controlled via MAF sensor signal offset. So will the Utec have the same issues with open air filters and supposed maf disturbance caused by aftermarket intake setups?

nmyeti,
Since you know better than anyone, maybe you can point out some differences between the Utec and the Xede for everyne that is interested but doesn't really have the same knowledge.

I'd also like to hear about the whole maf air turbalance/signal disturbance caused by aftermarket intakes...from you and also from Shiv and the effect it has on each system.

 

I think you missed the whole post above. Our plan is that the UTEC when released for the EVO will have stand-alone fueling. It will not use MAF signal offsets unless you specifically desire to run it in piggyback mode. The time it takes to implement this is unknown which is why i think your 10 week quote is a bit unrealistic, but we’ll see what happens in the near future.


The differences between the 2 systems are fundamental. The UTEC was designed from day one as a stand-alone management system and has all the hardware needed to pull this off from revision 1 (we are now on revision 6a for the WRX).

It's taken some time to get the software where we wanted, but we are almost there and will release it as a stand-alone computer for the EVO.

The UTEC has always had stand-alone ignition control. With a piggyback you usually have to program how many degrees of advance or retard you wish to add to the stock timing curve and then the piggyback monkeys with the crank angle sensor to fool the ECU into firing the spark early or late. With the UTEC we fire the spark when we want to fire the spark. We don't have to trick the stock ECU into doing the work for us. This lets us have some freedom from the whims of the stock ecu as well as prevents our own MAF signal distortions (due to piggyback fueling) from having any impact on our ignition timing curve.

Up to this point we've piggybacked off the MAF sensor for fuel tuning. For the EVO in the near future, this will not be the case. We will no longer have to trick the stock ECU into running the required injector on-times… that’s why we have a fuel map.

Some of the features;
Full stand-alone EFI control to 9000rpms
Progressive 3d mapped n2o/water injection control
2d stock FMIC water spray control
2-step drag launch/flat shift rev-limiters
User definable knock correction maps
5 user programmable maps with remote map selector switch
Wide band 02 logging (via separate TXS wideband unit)

There is a whole lot more that I am not at liberty to discuss. If you get to SEMA look us up, because we’ll be talking more about this product at the show.

Thanks for the info. Your website implies that it is piggyback type at least for fuel,etc. with stand alone features. It doesn't say that it is an all new system that is a complete standalone. That's why I asked the question eventhough you stated it was standalone in the previous post. Is the price going to remain what is on the website or is that incorrect also?

 

As of this time the website is correct. The website represents accurate information as of this moment.

In the future, near future that is, these things will change. I really want the EVO utec to be standalone from day one so you guys never have to deal with the update, but we'll see what happens.

As of this moment there is working UTEC stand-alone software, how long we keep it to ourselves to work out the bugs is up in the air.

Go ahead and release it
What kind of bugs? I'm sure it's nothing we couldn't deal with for now. How about releasing a few for testing on other Evo's like is being done with AEM EMS?

 

I don't think TurboXS is in the business of beta testing on customer cars (yeah, that's right, you know damn well what I'm insinuating).

 

It will make a nice christmas present for me
Im holding out till the Utec , i had it on my wrx and loved it.
