Cyl Mult (2) and Raw to Disk under ZT. can anyone explain what those do? sorry for the dumb question...

 

Raw to disk is basically a debug tool, it saves the raw data from the ZT2 as its recieved from the Wideband.

Cyl Mult is the cylinder multiplier, this is normally how many cylinders your engine is if you had one coil, however if you have a multi-coil ignition, it complicates things a little, in our case we have 2 coils and 4 cylinders, so the setting is 2, the reason 2 is the default so it will work out of the box for most users of mitsulogger... If we had 1 coil it would be 4..

The Zeitronix and UTEC loggers are actually standalone programs wrapped into Mitsulogger, and the program was designed to be flexible, I should actually have locked that value for Mitsulogger but I took into consideration that this program also works with the 3000GT which is a 6 cylinder and late model mitsubishis such as the eclipse which are available with 6 cylinder engines.

 

I don't want to comment on stabilty issues as my tuning setup is nothing but edge-case: MacBook Pro, Parallels beta. However, based on past experience, I wonder if MJ would be willing to comment/look into a couple things I did notice:

1. if I yank my USB cord while logging, mitsulogger hard-locks.
2. I can log output from the ZT-2 for about 30 secs before mistulogger crashes. In some logs, the output from the ZT-2 seems to die off a second or two (about 15-20 lines in the log) before the hard-lock, and in other cases, the log output is 1:1 with the OBDII output.

Another symptom with crash #2 is that I need to reboot windows before trying again. Any app that access the USB ports hangs in what seems to be a wait-for-lock state for a given port(s).

I can log as long as I want with mitsulogger, providing the wideband support is turned off. My guess is that the usb-serial adapter I have has some ****ty drivers (Keyspan). The one other usb-serial adapter I own/tried is the Palm adapter with what seem to be equally ****ty drivers.

I would pay good money for Zeitronix to develop an USB interface cable.

I'll try again tomorrow booted directly into Windows.

Thanks for the Heculean effort MJ, we all really appreciate it!

 

Okay, since I have tested the App with Keyspan Serial interface, and a few other brands, I doubt its a driver problem on your part.

I'm not surprised if it would lock if you yank the cable, as the port "disappears" in the middle of the application running, Although I do set timeouts and have some error checking, Its not easy to check or handle an error if the com port disappears completely.

Due to the nature of your configuration its hard to speculate what happened.. Since Mitsulogger and the Zeitronix logger are seperate apps, wrapped together, they should operate independently but who knows with the way .NET works. I need a few more reports from people to know exactly whats going on.

I need to know if this happens to people on a more stable platform, I did get one other report of something similar, but he said he yanked the cable before it died so I'm not sure if the problem is application related or serial related.

Most of my testing was on a bench, mitsulogger was running in demo mode and I was logging the serial data from the devices, SO if the problem is related to the Tactrix driver, and other serial port drivers, it might be something I didn't catch.

But, this is why I released an alpha so I can get some indication of weird problems.

 

I wrote a post about this on Aktivematrix as well:

Mitsulogger 1.5 will randomly shut down if I select my Zeitronix wideband. If I disable wideband logging it works fine, but with the ZT-2 selected it shuts down without any warning or error messages. It's as if I never had the app running. My system is a Dell Latitude D400, I am not using a serial to USB adaptor as the computer has a serial port, and my operating system is Windows XP. I wish I could give more help regarding the problem, but without any error messages or warnings I can't do much more.

Yeah I haven't been able to reproduce your specific problem, and I've been testing the zeitronix by logging for 2 hours without it failing this morning.. But I'm doing it on a bench so who knows.

Can you give me more information about XP? Do you have all of the current patches, etc?

I did reproduce a shut-down when the program couldn't read/write to the serial port, in my case I have 16 or so virtual com ports, several were duplicated, when I disabled the unnecessary ones, the app worked fine.

If I disconnect and reconnect the serial cable to the port, It will stop, give you an error, and when you hit OK it continues.. If I just unplug the USB serial port, it slows down both the Mitsulogger and the Zeitronix freezes, but its still running, it just looks like its hung, when I close the app it throws an error (it tries to close an open port that no longer exists)

However the app works fine as long as there are no conflicting ports so I can't reproduce your problem.

If your using a physical serial port, COM1 for instance, and you have a modem on COM3, its possible the interrupt its using is shared by both devices, in that case you might get timeouts or weird errors if one or the other has priority. I have a machine like this, a modem on com3 and serial port on com1, however as long as I don't use the modem, it doesnt give me a problem.

 

Out of curiousity, did you select any com port for the zeitronix? (Com1 or whatever) for the port? Or did you leave the dropdown blank? The wideband portion cannot tell what serial port your wideband is on.

I just cannot reproduce what your getting.. Weird..

 

THis may sound like an odd request, but also test the app in demo mode for the MUT portion.. I know this won't result in useful data, but I'd like to know if the problem is related to the Tactrix cable and driver, or specifically the wideband logger.

 

BTW, Please try to keep the troubleshooting and problem reports on Aktivematrix, its easier for me to work with you guys on my own forum as there's a specific forum dedicated to Mitsulogger and you can all create new threads for each of your problems so I can address them individually.

 

It's working well for me but it isn't remembering which items I set it to log once I lose the application.

I set my laptop in the passenger seat, reach over and press the button to log and from any distance it's difficult to tell if it started logging yet or not... some sort of visual indication showing that recording is in progress that's a little larger or colorful would be nice.

also it would be awesome to be able to set an audible alarm for knock above x counts. I can't watch the real time logging and drive safely.

great application, thanks a ton for making it for us.

 

Welp, I'm not sure why it doesn't save the settings, it may be you have something installed on your computer that either "cleans up" files, or prevents some files from being created, or you have a corporate laptop that is locked down in some way. Every user will have unique settings so if you don't log on as the same user, it might seem that way.

I've tested this with Zonealarm running and that doesn't seem to do prevent it from saving the settings. Anyway, if you do figure out why it won't save settings , let me know so I can document it.

I had a car on the Dyno on friday, and realized very quickly I needed some indicators and digital readouts that I can read easily, so that will be something that is added when I release a 1.6. I'm not sure if it will have audible alerts, but I will be putting in some indicators for knock and things you guys might like alot. Right now I'm trying to figure out which items to display. I'm also going to make a few changes that alter the way the logger works (when the logger is connected its always transferring data, but when you log, it will write it to disk. but I have to think about how I want to go about this)

I really want to get a few cars on the dyno and have some more real-world use of my program before I add or alter anything at this time. Thats why it looks a bit rough, also it needs to run on older laptops, where I'm already seeing some people with Win2k have a few problems.

 

MJ,

Nothing big but is there a way it can save your parameters for injector scaling and injector lantency?

Or create a template and it load from the template each time?

Every time I close out and get into ECUFlash to make changes and then get back into the program I have to change them to what I had, just sucks is all.

Otherwise the program is working great so far!

The software already saves the settings automatically. It always has.. If your losing the settings it has something to do with your Laptop's configuration. I just verified that it does save the settings so I didn't break anything in the new version.

You might have some sort of "privacy" software or something that periodically deletes settings as their saved in a location on the hard disk where your personal settings are stored.

I'll look into if its possible for these settings files to be located in the same path as the application. As far as I know it saves these files in a location where all software preferences are stored. I chose not to use the registry for this because many laptops and spyware/antivirus/firewall software prevent registry changes.

 

Your using a Zeitronix wideband? Just curious as I don't know who has what..

 

MJ,

Thanks for the tips, I checked everything and I am def. not running anything preventing my laptop from doing anything.

What I noticed is you have to hit the EXIT button on the bottom of the screen instead of through the top of the window. You must have your code in that button to save all the settings.

What are you programming in? VB .NET? C#?

I am a CS / IT major and program and fix computers for a living. Is there anything I can do to help right now? If not just let me know whenever....
