An interesting article, RiftsWRX. Are you soliciting feedback/discussion via this thread?

If you'd like, sure. It was more of an FYI, but I'd be more then happy to attempt to indulge you in any questions you may have.

Does it come with a manual? I'm confused on some of the knock correction stuff - for example with the LINK, you start off at a fairly low knock number, and increase it to account for noise. On your map, I see just the opposite of that - starting over 100, moving down to mid-80s.

Can you datalog ON SCREEN while you are tuning? I'd like to see what exactly is going on, and tune on the fly (ie a/f ratio is 13.3, go to load%/RPM and decrease fueling in that cell). How would you go about doing this, if you could? Involve opening two terminal sessions (is this possible?)

Can the UTEC adjust stall speeds? I know that you have the torque convertor mod which can change your launch RPM's. So you can launch at a higher RPM. Can this UTEC do that without having to do the TC mod?

Awesome. The interface looks solid and easy to use. Very nice writeup. Can you post some captured log files up?

Default stupid question?

remember guys, the only stupid question is one that was never asked... so here goes...

why were all the RPM columns filled with zero's on your posted logs and why does it look like you were running 14.7:1 AFR when at high TPS?

One feature I would love to see is on board data logging. I know the utec is supposed to be very expanable but everything is only expandable by the end user to a point. I wouldnt want to always have a laptop or palm with me so I can log, and besides I wouldnt want to be playing with some terminal program trying to get it to capture while at a stop light.

It would be awesome if txs made a small cheap device that plugged into the utec that had a secure digital or smart card writer allowing quick logging with a flick of a switch. With it logged onto a small disk I could easily just pop it into my computer and have a deep hard look at it and its corresponding graphs. Im sure you could fit a TON of logs on to a 8mb $15 card that has a abundance of card readers readily available everywhere.

I realize txs is a great company that always tries to bring out products to fill its consumers demands but I am a bit afraid that they wont be able to bring every little feature to its utec users. It would be awesome if txs wrote up some documentation on the way their utec works allowing others to produce devices such as the data logger, gui interface, and maybe even a small lcd tuning device like link has. Txs could always put some sort of constraints on the information or production of devices that would allow them to keep a firm hold on their important technical information. Im sure they dont want competitors to be able to punch up their web site and replicate parts of the utec's functionality. I bet people would be glad to produce devices if the utec takes off.

I really hope the utec gets big. The expandable model its built on is a awesome idea(wether its txs's or not, i dunno).

I only hope to be able to scrounge up enough pennies to get myself a utec...

A: knock correction... honestly it be a matter of defering that to TXS.

B: currently no. With a 19200 baud rate your limited to ANSI/ASCII based programming. There isn't exactly a way to split screen it, without using ANSI type programming, which may affect update speed on slower terminals. It's that fine line of flexability vs. versatility. Right now it's super flexable. But at a price (like what you just asked for)

C: Since it works on a TTY based feed, you can't have multiple "channels" of data going at a time. Not using conventional serial protocals. Usually one thing "locks" a serial port.

Stall is a factor of input torque by the multiplication factor of the torque converter, to a max amount.

So no.. the UTEC cannot circumvent a physical limitation. It could allow you to reach that ceiling more consistently by giving you more low end torque, but in the end, your at the limit of the converter you have installed.

I really don't have any. I happen to own a delta dash, and still use it since it's a completely open ended and customizable tuning solution.

But, FWIW, I've done a lot of my tuning via the seat of my pants, my knock link, my Greddy A/F gauge, and my EGT gauge. Just to show people what is possible with a few simple tools.

Cause when I took all the screen shots it was at my desk, powering the UTEC via a 9 volt battery.

Theoretically, there is no reason why this can't be done.

See, in essense, what happens is that the UTEC is serial based. You initially go to a main menu, with logging setup by hitting one keystroke. There is no reason why a logger couldn't be plugged into the serial cable that would normally go to your laptop, and have it send the number 1 which would invoke one of the logging functions, and have it start recording. When a disconnect is sent, it could either issue a ctrl-x to leave the logging back to the main menu, or the UTEC could be programmed to head back to the main menu on a carrier loss (if it isn't already, to be perfectly honest)

So, doing what you want, is rather simple. If someone could write the firmware on a programmable microprocessor you could build it right now.

There is no voodoo here... which is exactly why the TTY platform was used. You could theoretically write scripts and execute them via your favority terminal program to do mundane type tasks, like uploading and downloading maps. as opposed to all the keypresses.

Hope that helped bud!

Doesnt the utec mess up a lot of the data your ecu is reporting to delta dash? I would think that the utec is just about as good as deltadash, and I bet you can even use the dd log grapher to look at your utec logs.

Your right, I probobly could. But, again, I'm really only using a handful of tools. When I use the DD it's more to confirm calibration levels that the UTEC has programmed, to stuff like ECT, and IAT.

TXS website shows 12V DC input in the pic on their website. Were you using a converter on that 9V, or is it really 9V input?

9 volt worked just fine. I'm sure (like most electrical devices) that it's fine.

It comes with a schnazzy 9 bolt battery type plug, so you just snap a 9 volt right into it, and viola!

It's actually grossly simple.

But people who are looking into this, know what to expect.
