Well I finally am going to surface after months of lurking and learning. I have some questions on the UTEC and tuner interaction. From what I can see, the safc2 is going to be sold to a friend due to the fact the UTEC has the timing control feature that the safc2 didn't have. I am going to purchase the stage 2 kit from nino today, since I missed the TXS special. Anyway, since I have had my safc2, I have had the problem most have had. I had no idea if the adjustment made are making the a/f ratio leaner or richer. Since I am getting the UTEC, and trying to go all out on tuning, I need an a/f logger/display. I read around and the TXS tuner seems to be the way to go since I will soon own the UTEC, but how does it exactly funcition in series with the UTEC. Since information on the tuner is scarse, I have come here to some of my fellow UTEC tuners. From what I can find, it seems that the TXS tuner is a display and logger, which is fine, but why is there a knob on the front? You can't exactly make adjustments by the turn of a knob, even though that would be great. And does anyone know what the future gameboy feature is for? Is it just another display, or will you be able to make full adjustments on the fuel, timing, parmaters, and boost tables like the laptop will be doing? Any help on this will be.... well.... helpful.

 

The tuner is a great feature to have with the utec. I don't know why you'd look into any other wide band if you already have the utec. The wide band will display in it's own column on the datalog features of the utec. It will also display on the dashboard when you have it hooked up. You don't tune your afr by turning a knob, the afr is there for a target, something you use to know where to tune your timing and fuel to. The knob on the front of the txs tuner is a volume control for the headphone jack that plugs into the supplied knock sensor. It allows you to listen for knock while you're tuning the car. I'm unsure on the features of the gameboy, so maybe someone else can help you out there.

 

It acts transparently with the UTEC so you can work with it, configure it, and tune it.. when you do a logger-1 (a data log capture) It will append the AFR data to the log data.. Much more comprehensive and easier than matching it to your runs..

The Tuner itself is not a display device, but there will be a gameboy interface where you will be able to do some level of tuning with (from my understanding)

The dial on the front is a volume for the headphone jack on the front, its used with the tuners knock sensor (you don't need to install it if you don't use this feature since the UTEC does use the stock knock sensor) so use that knock sensor to listen for audible detonation.

Hope this answers your questions.. The new UTEC Firmware also has quite a few new and cool features that make the UTEC THE piggyback to have.. It has many of the strengths of a standalone ECU without the pitfalls associated with it.

 

I am going to purchase them both at the same time. I was looking into a wideband when I was just running the safc2 by itself. After some serious soul searching, I realized the safc2 was not going to meet my ulimate needs, and some sort of stand alone/piggy back was going to be needed.

I understand that, but it would be nice though. The logistics of how that could possible work are beyond reality though.

That explains the knob, thanks.

As for the rest of any relevant information, just add it to this thread. Thanks.

 

First off, the tuner being a display device as well as a datalogger was my understanding. The 3 digit led panel on the front, should display realtime a/f ratio, right? As for the gamboy interface, I haven't been able to find out much on it other that articles in some mags stating that it was coming.

As it stands for now, the UTEC is the ultimate piggy back as malibujack stated, and the tuner will drasticly help in the tuning functions of the UTEC.

 

Yes.. It will display AFR, I thought you had meant will it display anything other than just AFR, I just assumed that was a given..

 

Piggyback... don't insult our engineers . We drive your injectors and your coils. Piggybacks don't do that. Piggybacks don't let you type in actual Igntion degrees as timing either . With the fixed fuelling software release we are even making the full on decision when to turn on the injectors as well.

If UTEC could talk it would probably say "I'm not a piggyback, I'm alive"



I am loopy i am going to bed.

Thanks,

LOL Been a long day eh? This damn weather killed another tuning day for me! Agh!

 

Ya know.. Thats a good point, the UTEC isn't really a piggyback.. But its not a full standalone, its just the best parts.. Kinda like having a supermodel with a genius IQ, you get the best of both worlds..

 

Not to get off topic, even though I started this topic , but Jermaine, check your e-mails. I just sent one to you in which I have some concerns and need help. Thanks.

 

Is there a book or manual on how to use and tune th utech for the EVO?

 

You get a decent manual with basics and can fill in the rest from this forum.
The whole unit isn't that complicated to tune, it's the understanding of what you're changing.

 

When you say decent manual, do you mean the version 1.3 pfd file that's on Turbo XS's website ??

The "manual" that came with my utec was a photocopied edition of that - real great especially when most of the color photos in the pdf turn out almost ALL black on a photocopy.

You'd think for a thousand bucks outlay, teh manual would be a little bit better.

 

That's why I said decent and not great. The information about the product and how to change parameteres however is pretty good and they explain the basics. I downloaded the PDF version myself because you can't see **** in the b/w pictures
My opinion is, if you're going to modify the engine on your vehicle, you better the hell know what you're doing => people that understand what they are doing and know the basics about engines should not have too many problems working with UTEC after reading the manual and if you're not sure what you're doing then you either read, ask questions or you get it tuned by someone who knows what he's doing.
