the utec doesn't have an RJ12 port. the rj12 port is only on the tuner.

Connect the utec and tuner the way I listed a few posts back. Once you are connected, you can toggle between the UTEC and the Tuner within the interface, while connected of course.

 

For a good explanation of both open and closed as well as tuning for performance go to www.URDUSA.com...

 

Yeah, it'll look like this:

"TUNA" is TXS's slang for Tuner. :-)

 

So from what I understand is that, Ecu runs Closed loops from 1 - 1600 rpms and UTEC controls it after. Or so I presume atleast, because you can switch different maps under 1600 RPMs correct?

 

You can set the open/closed loop threshold to anything you want... Mine is set to 25% TPS and 2000 RPMs.

 

quick question, I bought a used UTEC and was wondering if I had to reset it? It also came with a selector switch. Is there a fast way to reset it. Thanks.

 

Yea, reflash it with the latest firmware.. It will get you right back to 'stock' settings.. I forget what the latest version is, but it will be fine if you reflash it..

 

Question about the Rev Limiter... When using the utec to change the rev limiter, is the new limit still a fuel cut limiter or an ignition cut?

 

I believe UTEC can only adjust the rev limiter for non-revups - via fuel cut. You can put a value in there for a revup, but it'll have no affect on a revup. You'll need to reflash the ecu for that.

 

Great thread!

Just a couple questions.

When you make a run what gear should you be in? Should you be at WOT till redline?

I know that 4th is closest to 1:1 ratio but does that matter when tuning?

Does the utec record my A/F ratio if I have a seperate A/F gauge?

 

yes 4th is good, yes WOT till redline.

UTEC wont record your a/f unless you have a turboxs tuner that plugs into your utec. I assume your talking about a seperate wideband? Your seperate wideband will not interface with the utec, although you can connect it to your laptop with a serial cable and use software that will allow you to mesh the widebands a/f readings with the utec log so you can compare. But there is some delay :P

 

actually, 5th gear in the 6MT is the 1:1 gear.

You can recoord A:F along with the UTEC data in 2 different ways. If you have the TXS Tuner Wideband, connect the Tuner to the UTEC and log into both of them and the A:F will log together with the other UTEC data. If you have a separate A:F setup, you can use a program like the UTI interface (www.jeffsoftware.com) to log the A:F together with the UTEC data.

 

Does anyone have that link to the guide on how to tune with the utec made by a subaru guy? I remeber seeing it and it had tons of great info.

 

Here's one...but I'm pretty sure it's not the one your thinking about http://www.wrxhackers.com/forums/showthread.php?t=2944

I think the other one can be found somewhere here though - http://forums.nasioc.com/forums/forumdisplay.php?f=141

 

Thanks thats exactly what Im looking for

 

...or u can download the MPS UTECLogger Software !

 

maybe you guys can help. I have my utec and tuner installed. I can read my AFR on the tuner and the utec works fine. My question is when I have the utec main screen up I can not see my tuner. Any suggestions, maybe something I am doing wrong. I have the tuner plug into the utec through the serial connections.

 

it should be Utec -> Tuner -> Laptop/PC. I'm a little confuse with your question..

 

I am running a usb from my utec to my laptop. I am running a serial connection from the tuner to the utec. when I am on the main utec page I do not see the tuner at the bottom to switch too. Its like the utec doesn't see the tuner.

 

You have to connect you laptop to the tuner and not Utec. You have to connect the Serial that is coming from Utec to your tuner. Then you connect your laptop to the Tuner. Like I said Utec -> tuner -> Laptop.
