TurboXS seems to have stopped participating in the Evo product when they released the 350z product, the market is much bigger for the 350z so their obviously spending more time on it. We have been complaining for almost a year before any reflash tools came out.

FWIW I will be switching back to the UTEC this week, I will probably not be using OLF features though, since I want the timing features, and the fueling using MAF intercept is okay with the reflashing setup.

By doing this, I get the ECU launch control, and the UTEC Flat shift feature.. (Two different RPM's)

I have 3 distinct tunes that I run, and its unwise to reflash the ECU as frequently as I have been. I would much rather run a base tune in the ECU and get it running perfectly.

I need to simplify my setup a bit, I want to remove the AVC-R and the extra stuff I have floating around that gets in my way.

 

Good stuff, I was looking to do the same thing with the evo, have my base map for my daily driving and autox and then fine tune my meth maps and nitrous with the utec...keep us updated jack...

 

OK Jack - I give.... how do you make the flat shifting work???

 

there is no real nls function, but raise the lc to the desired rpm and it works in all gears...

 

Yep.. The problem is with Open loop fueling enabled, is you override the stock launch control in the ECU when the TPS crosses 30% or whatever the UTEC is set for. By doing my base fueling and configurations in the ECU, and setting the ECU launch control, and disabling OLF, it should use the ECU's standing rev limiter for launch, and the higher RPM for the UTEC flat shift (launch control) will do the flat shift portion of it.

I have to verify this once my perrin EBCS shows since my car is in pieces right now waiting on a few small parts.

 

yo guys, we should make some kind of reunion for the 5th aniversary of this thread

 

I laugh b/c i forgot about this thread. I still have a Utec but dont use it. I couldn't get rid of that thing if i tried so i just decided to keep it even though i have a custom flash. This is the worst support i have ever seen out of a company. If this is the attitude than i dont know how much longer TXS will last as a company in the aftermarket car market.

 

Sadly there will always be a fresh stream of uneducated enthusiasts for them to bilk.

 

The hardware is good, actually, its an amazing bit of technology, I just wish we'd either get an update, or get me source code and I'll start writing my own code for it.

 

So Jack, with the UTEC can you see like in the Subaru's how much boost is the car running or you need the external MAP sensor? Im reading a bit on this, I loved my UTEC on my Subaru because I could change maps on the fly, reflash wont let you do that....

Let me know via PM or here better so everyone can learn.

 

Well, the Evo ECU has no provision to accurately determine boost, it functions primarily on load, which is actually a better method of operating, but is confusing for many of us.

In order to use and log boost, you need to hook up an external MAP sensor, a GM is easiest as the calibration in it already is close, but you can use any 5v boost sensor if you can calibrate it.

Map changing on the fly is the reason I'm using it at the moment. I am working with a combination of a reflash, and the UTEC, which means I"m not currently using the open loop fueling features, and only adjusting the fueling through MAF signal as all my fueling "Setup work" is already done in the ECU. But I am using it for boost control and timing. The secondary reason I'm not using OLF is that the UTEC does have a launch control / flat shift setting, but its one in the same, so I use the factory standing rev limit for launch, and the UTEC's flat shift feature for shifting. This is something that doesn't quite work right with OLF enabled as OLF defeats features in the stock ECU that would allow the standing rev limit to work (its because the OLF features were the only way you could overcome these things before reflashing became available to anyone)

 

So Jack, can you post some screenshots of the system how you see it on the UTEC datalogger? My main concern is seems UTEC's work miracles on Subaru's but on EVO's they seem kinda weak, I would like to read more, some support info might help, my Tuner is a Certified UTEC tuner, but still before I buy the product so I can change my daily driving map to a drag map or my Road Racing map, I need to understand how this actually works. If you have some good information I can read, let me know, also with the new software, any better results?

Thanks for your time

 

I have no idea what you really are asking. The UTEC works fantastic if set up properly. Only very few have spent the time to work with it long enough to make the numbers. Its not weak at all, the problem is once people start fiddling with it, they don't take the time to learn how to work with it, and then were moving on to Reflashes or standalones. Because you have direct control over timing, and depending on the setup, direct control over the injectors in open loop, there really isn't anything it couldn't do. This is something you really need to search for.

Basically how I do it on my car, is with a base flash for my daily driving and pump gas, slightly detuned for the most part, this way I have the drivability and other settings done correctly such as injector scaling and raised rev limits, and other fuel cut settings, on top of that I run either the ECU+ or UTEC (depending on the testing I'm doing) In my case, I run the UTEC in MAF Intercept mode (OLF Disabled) so the standing rev limit in the stock ECU works correctly, but its not required if you don't use it.

What I have found is any piggyback ultimately needs a reflash as a base to start from if you want the best drivability.

The maps themselves are really straightforward, it has its own load calculation and range, and you set it accordingly, if you ask for 5 degrees of timing, thats what you get. I would recommend taking the time to match the Knock settings in the UTEC with the factory ECU as its similar, but not the same.

The real deal about the UTEC, or any engine management is the tune is only as good as the tuner, and most tuners for the Evo seemed to shy away from it, hence it never got the same level of popularity as it does in the Subaru community. Additionally Evo owners in general seemed more reluctant to tune themselves, where in the subaru community, it was very common for people to do it themselves. Its got its good sides and bad sides for that reason, because people were more apt to tune themselves, the "Bad rap" it got for blowing up motors also was more prevelant, when in reality, its pretty hard to blow up an engine if you take adequate precautions.

 

I know many of you haven't gotten your hopes up about an update, but looks like we're going to get the short end of the stick again while they develop new products for yet another car.

The products they have in development are alot less complex than the UTEC, I would be upset if they announced a UTEC for it without supplying us with an update.
