TunerPro RT EGO Correction

[WiredForStereo]

08 XB12XT, modded muffler, front exit.

I was following the walkthrough posted by ReadyXB here: http://www.buellxb.com/Buell-XB-Forum/Buell-1125R/tunerpro-datalog-help It's an excellent explanation that was lacking from other sources. So I followed it to the letter except he appears to be using and older version of TunerPro. Mine doesn't have the "LOAD" option when creating the table. The closest thing is "Load1". I have tried it with both Load1 and with TPS and all of my EGO Corr. values are always 100 across the table.

I know this bike needs retuned because I don't have a flat spot in the middle, I have a dead spot and I can tell from the oxygen sensor logs that there are areas that need work.

I can do data logs, change settings, it all works, but I cannot get the EGO Corr. to read anything useful. Any help would be appreciated.

Hi, the values "Load" and "Load1" that are used for the live data and logging are defined in your .adx file. Which .adx file are you using?

In Tunerpro RT v5.x, go to "Acquisition" -> "Edit Definition....", then expand "Values" in the left column and make sure you have "Load". Note that the values may not be in alphabetical order.

Alternatively, you can search for "Load" by opening the .adx file in a text editor and searching for
<ADXVALUE id="Load">.

Is it there?

And welcome to the forum!

ReadyXB, thanks for the response.

I have three ADX files, two from I'm not sure where, maybe the TunerPro website or the ECMspy website, I do not recall, and one from Xopti. When I started this thread, I was using one of the others. Neither of them have the "Load" value, only the "Load1" value. The Xopti file has both the "Load" and the "Load1" value but when I set it up, and play back the log, no cells are filled at all. Plus, that ADX has no dashboard, no gauges, or monitors.

So it looks like I need the ADX file. Do you know where to download a properly equipped ADX file?

Or alternately, you could give me the info on how to add the "Load" value to my ADX or modify the "Load1" because I don't need it anyway.

Thanks for your time.

For your 2008 XB, you need "Load" in the adx, or at least a value that lives at offset 0x1B in the data stream.

Rather than trying to correct your current .adx file, please give mine a try. It is for DDFI-3 and already has dashboards defined, as well as a few History Tables.

**Note: you need to record new logs using this adx. Trying to load a logfile recorded with a different .adx may not work.

Thank you, I appreciate it so much. I'll try it as soon as I get home, if it's not raining.

By the way, I have been trying to figure out exactly how to do this for weeks, and your posts were the only place I could find that actually gave the steps how to do it. Everywhere else it just said to do this and this and this, but never said *how* to do those things. I really appreciate your walk through and your assistance.

Alright, I had the chance to get everything loaded in and take a ride last night. Everything worked out exactly as it was supposed to. I have my EGO correction numbers and applying them to my maps. It ranged everywhere from 75% all the way up to 120%. Some major changes there.

Another question, is it normal for my TPS not to go all the way to zero? I never get any values lower than the fourth line, I forget what position that is. I've done TPS resets left and right, and it always goes back to the exact same spot. Seems to run fine though. I've used TunerPro to fiddle with fan on/off temperatures, idle speed, etc, but the TPS doesn't go to zero. Is there a set screw somewhere that needs to be adjusted or is this normal?

readyXB- the adx file you attached is for DDFI-3, will it work as a defintion file for an 1125? Thanks

 

[WiredForStereo]

ReadyXB, could you also talk about tuning the idle?

Yes, it is normal for DDFI-3. In basic terms, when the TPS is "reset", whatever the angle is with the throttle closed -becomes- zero to the ECM, even if it is actually 4º.

Is there a set screw somewhere that needs to be adjusted or is this normal?

2008+ model year Buells utilize an Idle Air Control device to control idle, as opposed to a throttle screw. The IAC is controller by the ECM to maintain a target idle speed, which is influenced by factors such as engine temperature and battery voltage. Depending on your ECM firmware, you may be able to easily change the idle speed via the "Idle Air Control Setpoint Table".

Yes! The ECM's live data and commands on 2008+ 1125 and XB models are the same.

You may want to change the dash to add the second O2 and Load, if desired.

Thanks ReadyXB, I wasn't talking about the idle screw on the previous years, I was talking about some sort of set screw or stop that prevents the butterfly from closing all the way and getting to zero. But if it's normal, I won't worry about it.

It looks like your bike does the same thing from your original thread, your 0, 6, and 10 rows are blank, as mine are. Also, the first four columns are all zeros on the map itself. I've seen in other threads where people have changed the map to be able to utilize those four columns and increase the resolution of the map. Is this worth the time? What are the benefits? Have you done this? Do you know how?

Thanks for your time.

My apologies.

Any thoughts on tuning the idle?

Also, how close do I want to get it? +/- 5%? Closer?
