Default Evaluate my UTEC datalog :)

So I managed to get my laptop working for one quick run (then it locked up hyperterminal -again....more on that below).

I've converted the text file to Excel and highlighted the ranges where I was in gear at WOT. During the pass I had a few flickers of the CEL (indicating a knock event) but after checking out the log file, nothing was noted. I really have to do more datalogging to find out if its really missing these events or what....

Anyway, here is the location of the file for you to download and view (just to get an idea how this thing runs in the "real" world).

http://24.79.147.156/utec/logs/utec1.xls

About the laptop issue......

This is the second laptop I've tried to datalog with. I had the same freezing issues with my FJO wb02 software and the PCLink software on BOTH of my laptops (running WinXP/Win2K). I've tried just about everything in the book to get this damn thing to work. Well I'm off to grab another laptop....this one will be simple (win31 or 95). The lockup is so bad I have to either hibernate or restart the system to get it to connect to the UTEC again

I can't see it being an issue with the UTEC...

how are knock events determined ... I don't see any where in your logs a knock sensor value ....

you might want to check the cable itself. That may be the issue if you have used the same one in all cases

Tried the cable, no luck. The UTEC comes with a cable and I had an old one from when I tuned my Link.

As for the knock events.......ya, nothing showed up. I could feel the timing being pulled and did see the CEL flicker. Just nothing in the logs....

I'll try again tomorrow...

The knock detection runs much faster than the logger. The logger only takes a snapshot of the engine data. This is why the logger doesn't always show any knock counts, however because the timing is retarded for a number of crank cycles this can normally be seen on your logs. I had a look at your logs and rows 257, 262 show lower than normal timing.

Your Hyperterminal(tm) issues are frustrating for me. I'm not sure what to suggest at the moment, please keep us all posted.

Perhaps you should try some different terminal software?

Tera Term Pro?

Make sure you are set to "8 N 1 None"

It's more like, lock, load, and FIRE!

I have a Palm IIIC, a Compaq iPaq 3870 and a Compaq iPaq 3760.....one of these should work!!

I just graphed the data... If anyone wants me to email them the excel file please feel free to email me at jcb@cbcl.ca.

Some observations:
- based on the data I see it looks like you had some timing pulled midway through third gear and then it advanced a bit higher after the event. odd. hmmm
- your timing in fourth gear was pretty consistent... very little advance towards redline.
- The MAP signal seems to be fairly erratic. Why would that be?

JC and others... I need to get most of you updated to version 2.2a of the software soon. In reference to your question, the map sensor is fast enough to catch the opening of your valves. There are moments of low pressure and high pressure in your manifold, and the map sensor will see this.

We have smoothed this out a bit with 2.2a and will have that on our website soon.

As to the timing issues; the UTEC will retard timing and then allow it to advance back to the programed rate as soon as the knock event is over.

How does it get the AFR? Is it accurate?

please don't take my observatiosn as criticism. If fact, based on this run, I think this unit is doing everything you claimed it would. I have yet to see anyone mention the launch control feature however... has this been scrapped?

I guess we have no way of looking at the timing/fuel map unless we're connected to the UTEC huh? It would be nice to have a program that could load the UTEC map info and display it for viewing/editing.

I'm not sure (without loading up hyperterminal) what the timing is *supposed* to be at...

Why does it display "rich" at WOT instead of a value for the AFR?

What does it mean when it says "rich"? Just curious.

If you were to search back on the original Delta Dash threads, the W/B O2 sensor on the WRX looses it's reliability in terms of reporting, sometime under 11.172:1 As a result, the UTEC will stop reporting under that point.

That's going to change as an add on will come out later on that will put a VERY ACCURATE (read $$$) O2 sensor in with the UTEC.. it'll be around that time that you will have TRUE lambda based tuning.

Meaning.. you can type in 10.2:1... and you will GET 10.2:1...

Is that the cat's-ass or what?

JC,
Launch control has not been scrapped. It's just not in THIS version of the software.

This was discussed in a different thread.....

to bring you up to speed though, the factory o2 sensor is in NO WAY accurate beyond 12:1 a/f. Rather than showing inaccurate values, TXS decided to show "rich". You'll need a true wbo2 for accurate a/f info.

A/F targeting is just silly, silly I tell ya. How can you get any more easy to use? Its almost an autotune. Adjust boost and timing and then punch in an A/F target. Glorious. So, what about that financing? Will you take an even trade for a diamond engagement ring? What?? Its insured.

I can`t wait for this.

Any general time frame when we might see this? months?, year?

No clue.....

Right now we're walking before running...

What does that mean...

the next thing your going to be seeing is true MAP based, speed density fueling... (read: NO MORE MAF)

That is the precursor to lambda based fueling.
