Default Any Bottom Line UTEC 1/4 mile times?

I was wondering if anyone has run the 1/4 mile with a stock car using the UTEC tuned maps? Any results?

Sorry TXS.

I'm very pleased with the UTEC so far. I have forgotten how to drive which had nothing to do with the UTEC. I think part of my problem was that I had my nose down looking at the screen so much, a few times someone had to yell at me to move up while waiting in line in order to drag.

I definitely wasn't focusing on my launch, I was thinking of how I was going to change my timing. I think I need to increase it, but Nathan from TXS also notes I need to maybe not increase that much due to the 91 octane piss they have on the island. I've also since put in an uppipe and have some Samco hoses coming, so I'm going to have to have to look at maybe changing my fuel, as well.

In my mind, I think the UTEC is the best thing since sliced bread; I wouldn't trade it for the world.

Default Huh?

Doesn't sound too good, and it doesn't make me want to run out and buy one without any proof that these maps are superior to the stock. Some of us have problem stock ECUs and would like to do the change, without voiding the warranty, or having to remove a bunch of aftermarket hoses and downpipes before taking it to subaru. Thanks for the information

I don't think we've ever claimed a given 1/4-mile time for a car with a UTEC. 1/4 mile times are way too driver dependant to make such claims.

On the other hand, at the east coast Subaru shoot-out 2 of the top 3 cars were utec equipped. Since then Iíve had a customer run 113.5mph in the 1/4 without n2o on his UTEC equipped WRX. The UTEC has been into the 11s. The UTEC has taken an automatic WRX to 13.0@105, and a few WRX's with stock turbo chargers have made enough power on our dyno that I feel they could make it into the 12s. A UTEC equipped WRX has won its last 3 events in its region in autox. I'd say there are more than enough people showing just how much power you can unlock with this ECU.

Here is the kicker, and everyone should consider this. It's more that likely that the UTEC that we ship you will need some tweaking and tuning. This is the reason that we made it user tunable. If you are not prepared to play around with some of the maps to get the most out of your car, you might need to consider other forms of engine management. Our base maps are going to be evolving over time, and will get better, but frankly there is enough variation in fuel quality across the country that it is unreasonable to expect that you'll both get the most hp out of the UTEC as possible and that you'll never have to touch it.

The utec is a User Tunable Engine Computer. Every car is a little different, and you the "users" are going to have to tweak the maps just a bit. Even our tight nit Bata testers found this to be the case. What worked for one didn't always work for the next. As more maps become available, I think you'll find that you have to tweak the UTEC a bit less, but with the big change from summer to winter fuel, I suspect everyone is going to have to add some fuel into their maps.

If you are hesitant about purchasing a UTEC, please donít. If it makes you feel better by waiting until the unit is a bit more proven then by all means wait. I would rather you wait to be sure that youíll be happy than to have an unhappy customer out there. Donít get me wrong, we are in this business to make money, however we want to do it one happy customer at a time. Iíd rather loose a sale or postpone a sale then just try to make a few bucks off of you.

I understand what you are saying, but a dyno or a range of 1/4 mile times might convince me better. Specifically on a stock drivetrain. Thanks.

I guess the question is begged... what do you consider stock.. on one post you talk about drivetrain, but drivetrain isn't powertrain.

FWIW, I've personally tuned a handful of "stage 2" cars.

Those are exhausts.... not even up-pipes.

And those run with strong midranges and CONSISTANT performance levels.

one of those exhaust only cars ran 13.8's IIRC, on mediocre launches (sorry Cody heheh)

Not bad for just an exhaust and CONSERVATIVE tuning... and when I mean conservative... I'm talking about ZERO tolerance for knock potential, and LOW EGT's..

4 of us in this car WALKED AWAY from a built RSX-S starting AFTER 80MPH...

Which is saying a lot since anyone with half an understanding acknowledges that an RSX-S will eat a stock/mildly modified WRX from 60MPH on.

How's that for a testimonial.

I would like to respond to your question although it is not the answer you may be seeking. Judging an engine mgm system by the times people are running with them is really not the best gauge of a product. With a safc and delta dash, I was able to run a 12.52 @ 109.5 in nearly 80 degree weather with an average to poor launch (1.80 60'). Does that mean I have a safe, yet aggressive tune and that I couldn't benefit from the utec? No, of course not. Although my a/f was pretty good, my timing could use a better curve that would be safer and provide more power.

I have read enough dd logs and played with a/f and timing a bit to have a good idea of what the ecu does and the potential of the car. The stock ecu is a good one but it has limits trust me. Although I don't own one yet (on order), the utec can allow you to tune all the important variables for power enhancement. Your track times will not be determined by the addition of a utec but by how well you know how to tune the car. The utec gives you the tools you need from stock to highly modified. It is not just a guessing game but you can monitor knock, boost, and a/f to finely tune the car. For the price, there has never been anything even close to date that can offer you daily driveability combined with safe, reliable power improvement.

Nathan, make that the last 5 Auto-X's .

Regardless, I think the UTEC is awsome. The ability to tune the maps the way I want and need them is really great. Being able to switch from 117 Octane C16 to 93 Pump only requires a flip of a switch.

Did I mention the knock correction, it has saved my ass several times.

I think everyone is missing my point. You can have peak powers and torques and sharp curves that don't give flat power response. As for a 13.8, I know people with the stock power train that do that with an MBC.

I would buy the UTEC, if it came pretuned with a map that put my car in the low to mid 13's on my stock powertrain. Then as I modified the car I could retune easier with the UTEC.

Seeing the differences between those using the UTEC and the stock powertrain with an MBC makes me think subaru did a better job tuning "most" of their ECUs, than we can buy in an aftermarket package.

I understand that most of you UTEC users have a lot of mods which must be tuned to. My goals are short and long term.

Very good points... people should listen up.

I don't want anyone to take this the wrong way, but the UTEC is not for everyone. If you are looking at it to be a magic bullet for your desired time slip, it's just not going to happen, and I would suggest you save your money.

As Iíve stated in several other threads, the stock ECU with an MBC can sometimes run very aggressive timing that will allow you to make a great deal of power in the short term. I've seen cars on the dyno that would detonate, and yet the stock ECU would continue to crank up the spark advance. I've also seen situations where it would pull timing, but not quite enough to keep the car away from the detonation threshold.

If all you want is for the UTEC to duplicate the same timing and fuel curves as the stock ECU under those conditions, I suggest that you NOT purchase one as Iíd hate to have you be the first to turn the knock control off and blow your motor.

If however you want to attempt to get the maximum power out of your motor without having it detonate to bits the UTEC is a tool that will allow you to accomplish this goal.

The bottom line though is that Subaru didn't put 300hp worth of parts on the car, and to expect to have the stock motor make that sort of power though the stock parts is a recipe for disaster. If you are looking to cook that up with the UTEC, please donít.

The UTEC is not about bottom line ľ mile times. Although, it has however more than proven itself very capable in such a short period of time, it is more about giving the end user access to a flexible, reliable, and safe engine management system.
