Valet = Waste-gate boost level, Map #1 fuel map, and retarded ignition timing (might implement a rev-limit with the new version of the software as well).

There is no economy map, but you might be able to tune one for lower octane as some of the WRX owners have done.

still confused... If you have a stock evo i see the maps working, but for example my list of mods you would have to make a custom map no? Still not 100% sure exactly on this product, need some more information.

IF you get a dynotune do you only program 1 map how does this exactly work? I'm sorry just trying to comletely understand your product so I can take it in to consideration in the future.

 

Evo11v - I have been reading this for the past 15 minutes, this is giving me a better understanding of the product. A lot of the features that will make this system shine above most are in development. The manual is here: http://www.turboxs.com/EvoUTEC1.pdf

 

We can build any number of maps with a custom tune. We can run more aggressive boost and timing levels for a "race" map, or we can optimize the map for everything from 91- octane to high-octane leaded race fuel.

The UTEC is user-tunable so you can also make these mapping changes if you know what you are doing.

The sensor signal is still being manipulated no matter what sort of testing has been done. Are you implying that the guys at chip-torque have more resources or a better understanding of detonation on the 4g63 then the Mitsubishi engineers?

By the way, our dyno is load bearing as well there is nothing special about that and we've spent a great deal of time on the knock threshold settings.

We are also rather conservative on our ignition timing in the areas where the motor is a bit noisy. By the way what ignition timing are you running up top? Do you know? My maps are set to about 17-18 degrees. My stock ECU wants to run 23-24 degrees of advance. With the UTEC at least I have that data-point to compare against.

If you set the timing level to "ecu" the UTEC will use all factory knock correction settings. You can still use the boost control, fuel control, launch control, spare solenoid driver, wide band AFR logging, and every other feature but ignition timing adjustment.

At this point I almost get the impression that you are here to carry the standard for another product, and not actually here to ask questions about the UTEC. You are here to attempt to point out what you think are its deficiencies. We can go on about this all day long but it's not productive nor is it the purpose of this forum.

We will have to agree to disagree and leave it at that.

Another quick question. When will the TXS Stage 2 map be available for users with the TXS DP and Cat-back, any numbers as well? I think once the map library starts to open up a lot more people will jump on this unit. Also is the Stage 1 map feasable with the Walbro 255 pump in there or should an adjustment be made under the parameters section?

 

not true Nathan the reason we dont mesh is your a presumptious person that always speaks down to people. Your Nathan from TXS the professional. You misunderstood about a different product and decided to include it in a comparison I dont care about that anyway I wanted to know about the UTEC and its controls and features you wanted an easy welcome without having to get into the technicals. I know we all miss Phil and now we must get talked down to to eek a small bit of info about the actual workings of the UTEC. BTW Im running a tinsy bit more than your basemaps up top.

Let me ask you Nathan did I insult your product one time or insinuate something false about it? Were my questions on topic and informed? Were yours? For whatever reason you wanted to loose your temper feilding technical questions I dont think you were right you chose to get mad because you refused to recant a comment on a product you knew nothing about. At least I try to find out before I blab

 

I know enough about the knock sensor signal attenuation that happens with the xede. I didn't blab about it, I was using it as an example to point out that there is no user-tunable EMS on the market that truly uses the factory knock control system. They all either monkey with the actual knock sensor signal or screw up the ECU's load calculations. I am aware that the xede has the ability to both increase and decrease the knock sensor signal level to the stock ECU. The fact is that it is intercepting this signal and putting it’s own stamp on it. It is massaging this signal, which the stock ECU would
normally use as a reference for knock detection.

According to the Vishnu website


Further quoting Shiv directly

I resent that fact that you think I am blabbing about something I haven’t researched. I’ve been reading this site and following almost all the other shops results since before we even purchased our EVO.

I do not in any way claim the UTEC’s system is superior to the factory Mitsubishi system or even the Xede’s manipulation of the that system. I do not claim that our knock thresholds are 100% spot on, and I fully acknowledge that the average person should not be setting these thresholds on their own. I further want to state that I don’t think the average person should be tuning their ECUs. Just because something is easy to plug in doesn’t make it easy to tune. I’ve had this conversation with one of my friends at AEM several times. I don’t envy their tech support load.

My tone with you comes mostly from one of your first posts on this forum

That post is combative and derogatory. It was at this point that I put you in the camp of a troll and I think the closest I’ve come to actually expressing that feeling during this discussion is the last section of my last post where I said


With the exception of the above paragraph I was trying to maintain a discussion/debate. I don’t think I was “talking down” to anyone. Why is it that when I have a point-by-point discussion/debate it is always taken as me being an ***? I know in am very direct and if I offended you in my response then I apologize. I will say one thing, you have me at a serious disadvantage; you at the least know my name while you remain anonymous as you throw your barbs in my direction. I guess that’s the life on the Internet; but you have no right to make judgments about me based solely on what you’ve read. You have no right to act like you know me when you’ve never met me and likely never will. If I’ve pissed you off in person, so be it but at least let me know to whom I am talking.

The point is this, there is no system on the market that uses the factory safety net 100% short of say maybe a re-flash. If you are overly concerned with keeping the factory knock system 100% in tact you may need to look for other engine management, as the UTEC is not for you.

The real issue here is has to do with what we learned in the Subaru world. When you give people a knock detection system and tell them it works pretty well they will strive to tune the last HP out of their motor and rely on the detonation detection system to save them. While it works a large percentage of the time (based on the number of happy UTEC customers we have vs. the number that have destroyed their motors for one reason or another) it is not ideal.

If you are setting up a map that requires the intervention of the knock detection system very often, I think you may have gone to far in your tuning. With that said, I am amazed at the AFR levels that some of the EVO guys are running on pump gas. I suspect a few of them are going to learn the lesson the WRX crowd is just now starting to come to grips with. That last HP just isn’t worth it.

 

Great comments I must say and It takes alot to devote an explaination of your products weakness/ not so flashy attributes so candidly. Having obviously clashed and chaffed you from the begining I can understand your current reservation. But alas Nathan there are some comments still about the "shiv in his own words" quotes that look like a direct and conclusive rebutal to most members but I have a good feeling you are in most part in agreement - Of course it "messes" with the knock signal and I think you allude to it being much different than the UTEC. The main point is we need to quite focusing on all the "Goodness" of the UTEC for one second and please tell us publicly how do we properly set the knock threasholds?

As far as who I am Im a WRX UTEC user and have spoken to you many many times on the phone, internet, email. I cut my teeth on the UTEC and learned tuning on the difficult and moody WRX. The UTEC was a blockbuster hit with us all and yours and Phils support was vital for the thousands of noobs that bought your computer and had massive learning to do and massive power to screw up.

So lets not butt chests this is a good smart manageable place to get down and dirty with helping everyone out on properly setting those threasholds.

Ill call you soon so we can speak and avoid any unneeded animosity

 

Well Nathan in all do respect every time I talked to you. You have been patient and answered my DUMB questions in complete detail. That speaks highly of your personality. At least in my book.

Hey here is my grip does the utec do a smooth transition from factor ecu timing to Utec control??

Also does the utec's data logs show the actual factory timing value when the ECU is running timing?

I'm a xede user and you can let the ECU completely control the knock retard. (That's how I tune).

My best
Eric

 

Eric,
Currently the UTEC does not interpolate between stock ECU values and our base-map. The TXS base-map needs a little extra ignition timing in the low end to help bring the transition a little closer. We can make fairly large jumps and not "feel" the transition, but the current base-map is just under advanced down there.

On that note, I am setting up a MAP as load base-map in the morning. Using the closed loop boost control and MAP as the load reference makes life a whole lot easier due to the way I setup my map scaling.

The UTEC data-logs always show both the ignition timing the UTEC is running and the ignition timing the stock ECU would run.

 

Whats the word on the new flash? I am porting over the buschur map from the S-AFC to the UTEC and was thinking I should hold off.. I'm targetting about 2 weeks before I get the car on a dyno any chance I can get it by then?

BTW, I am going to contact Buschur about the map I'm working on, if its ok with them, I'll post it for everyone with a UTEC in Open Loop Boost (Basically plug in and go) and the Buschur stage 1 components.. I don't want to step on their toes so I'm going to chat with them first.
