This is a great feature I use frequently.

Thanks,

PS - one thing that I've thought about adding to histograms is the ability to only add histogram data if it falls under some user-defined range. This is good for statistical rejection of data that is good and valid, but out bounds for what you're interested in. This would also alleviate your issue,...

dfddfd2

I would also use this requested functionality frequently.

If you are referring to signed 8bit integers in the -128 to +127 range, then just specify the value as signed integer by checking "Signed" in the XDF definition editor.

Expected?

I had asked Mark for this a while back. It's a pain having to go back through the list and re-select the items you want with every export.

If the MAF is hot wire type, it should compensate for the IAT difference.

dfddfd2

He tuned at the higher temp., so when it cooled off 10ºC, it ran lean, which makes sense. The question I have is how is the fuel being metered? Is it MAF, speed/density (MAP). alpha/N?

Mark,

This is the same problem I reported 6/2309. There are some example XDLs in that email.

Dave

dfddfd2

I'm pretty sure this problem has been around since ScannerPro. I know I've told Mark about it a long time ago.

dfddfd2

The AEM UEGO uses (V*2)+10=AFR, so in your case AFR=(10N/255)+10.

dfddfd2

duty cycle % = injpw * rpm / 1200

injpw = injector pulse width in msecs.

dfddfd2

I'll third this plan. If an error occurs receiving a packet, the error counter should increment, but the entire packet should be ignored.

dfddfd2

You might try 78-(X*0.351563) or 78-(X*351563/1000000) as a work around in the mean time.

Dave

dfddfd2

It's normal for the AFR to oscillate around 14.7 with a narrow band O2 sensor, although yours seems to vary more than usual. Your NB sensor may be slow to respond causing greater swing before changing direction. Vacuum and/or exhaust leaks can also cause unstable AFR readings.

Dave

dfddfd2

Setting the fuel map cell value to 0 doesn't disable closed loop. What are you changing to turn O2 feedback off?

Dave

dfddfd2

I suspect the O2 sensor. Try using the NB output from the WBO2 as input to the ECU.

Dave

dfddfd2

Are you using the simulated narrow band output from the WBO2, or the stock O2 sensor as input to the ECU?

Dave

dfddfd2

There may be a problem with your XDF file where the fuel map address is incorrect.

You must press "Update" after making changes while emulating in order for the change to be sent to the ECU. It doesn't matter if the engine is running.

Dave

dfddfd2

Take the top cover off the ECU and see if you can identify it. If not, post a pic and I can tell what it is. I need to know if you have a realtime daughter board. Map tracing is what you described as "the cell is highlighted in the tuning software tables for the current operating condition"...

A11-B44 G70 is for US 91-94 240sx with KA24DE and manual trans. You will need a consult adapter cable for data logging using consult, however TunerPro RT does not support the consult protocol. There are programs available, such as "Nissan DataScan" which use the consult protocol, however t...

What are the part numbers on the sticker on the ECU?
What Calum daughter board is in the ECU?

Dave

There was a problem editing scalars in the previous build. Try the most recent build 5197:

dfddfd2

Sounds like you need to copy your original bin to another file name and use that for comparison after you modify the bin file you're editing.

dfddfd2

"zoom feature for 3D maps" is already there. Try ctrl+shift+left_mouse_button+move_mouse_up/down

dfddfd2

I like the sounds of that!

Will there be access to the GUI elements/graphics also?

Thanks,
Dave

dfddfd2

Yes. Define a Flag/Switch @ 0x4009, bit number Bit 1.

No way I know of to show words for values.

Dave

I'm developing custom firmware for the ECU called TunerCode along with XDF and ADX files for TunerPro V5. If you're not already a member, you might want to join http://www.sr20forum.com/ . Details will be available there in the http://www.sr20forum.com/calumsult/ forum soon. My sn there is dfddfd2. ...

Exhaust leak maybe?

dfddfd2

maybe it works on that ecu because that ecu uses 200ns speed chip and Z32 and Q45 use 85ns speed chip a much faster, so if the emulator ribbon is too long it would be too slow of a read on these ecus. By the way would you share some tunes for that KA24E ecu? What is the clock speed of the CPU in th...

dfddfd2

I use an Ostrich2 on a KA24E ECU without any problems, and without a socket booster. It uses the same CPU as the RB20DET.

dfddfd2

Yes. Hold the ctrl key down while selecting the points you want to move.

dfddfd2

I hope someone in the LT1 community answers this, because the same table exists in Nissan ECUs, and I would love some feedback on why this is implemented.

Dave

dfddfd2

Looks like you might need to changed the Buffer Addressing End Address to 07FFFF. The default comes up as 007FFF for the 29F040B.

dfddfd2

There is a "Point Selection Radius" field on the Preferences dialog. I haven't played around with it, but you might give that a try and let us know how it works.

Cheers,
Dave

dfddfd2

You can cut and paste from a spread sheet or text file. I created a spread sheet that has all of my axis labels defined.

Cheers,
Dave

dfddfd2

You probably need the FTDI USB device driver available here from Moates.

dfddfd2

No question, Mark is a very smart man and great to work with! His vision for intuitive user interfaces for tuning is incredible.

You might try Moates Upload/Download area.

F = C * 9/5 + 32

edit: I should say that '*' is multiply, '/' is divide ....ie; F = Cx9/5 + 32

dfddfd2

Mark, I'm running XP, so you must be thinking of someone else running Vista. As you know, ScannerPro has some "qwirks" and I'm still building a bugs lists for it, and TunerPro also. Let me know when you would like to have them. I have been able to get some excellant data, using ScannerPro ...

Your best bet is to search and read through the Nissan tuning forums (I linked one in my original post), then join the forum and ask Nissan specific questions there. You'll find other Nissan tuners using TunerPro also.

I haven't yet, but plan to add support for these Nissan "MSB" maps to TunerPro. I just need to figure out a smooth, generic way to do it. I tried using the & operator (X & 127) and all the map values displayed as 0, so maybe thats not working. You might implement the conditional a...

If not, is there a way to edit an ADL file, to remove samples?

That would be a nice feature to have. I asked Mark a while back for that capability for ScannerPro logs also. Maybe we'll see it in the new version.

dfddfd2

That's just how Nissan decided to do it. The pictured map is correct. Take a look at the conversion tab to see how the numbers displayed in the map are converted.

Cheers,
Dave

dfddfd2

Your fuel map looks normal. Values above 127 indicate closed loop operation. Check out theHybridka Forum for lots of Nissan tuning information.

Cheers,

It might be the "Use Low Range" and "Use High Range" fields in the "General" tab dialog.

The BinSize in the xdf is set to 0xFFFF, but the bin is only 0x8000. Try that change.

The question was asked because I was curious as to what you would want to see in hex after a conversion. Your attitude will likely result in no-one wishing to engage in discourse with you. A constructive example of why you would need such a feature will help people to understand things better. Dex,...

Of course there is. I wouldn't have reported this as a bug otherwise.
