Adding HOT keys for starting and stopping a Data log session

[BRAAPZ]

First off, a major thank you to Eric for MT225 release. It is Absolutely incredible. MT release coupled with MSnS-E 029q2 running on a V-3.0 MS-I make for a very powerful, option packed EMS. The new menu layout within MT release is much more intuitive, thank you.

Another thank you goes out to Phil Tobin for his “Mega Log viewer”. Just got it up and running yesterday, and ran couple of passes and Mega Log Viewer is AWESOME!!!! Thank you guys.

Ok, back to the topic.

I’m using MSnS-E in my Race car and the lap top sits in the passenger seat. I would like the option to be able to start the data log session and stop the data log session using say the “space bar” on my lap top for convenience sake. Reaching over to use the touch pad while all harnessed up is a bit of hassle, to say the least.

Is there any ay to set up “Hot keys” for data logging “start” and “stop” other than the “Alt L” for starting and using a drop down menu for stopping?

Sorry can't help but I have the same problem. Even better would be an option to automatically start datalogging from a trigger, ie when MAP rises above a certain KPa or rpm goes above a certain threshold.

Right now I have the same problem. Even beyond the difficulty of building a track legal mount for holding the laptop open and accessible during track use, trying to hit datalog and say "yes, use this filename" is just a non-starter for track sessions.

Is there any other way to trigger datalogging ?

preston,

Look for a section of the custom.ini file like this:

Code: Select all

#unset AUTOMARK_LOGGING_FEATURES
#if    AUTOMARK_LOGGING_FEATURES
   [OutputChannels]
      ; Make up some variable names...
      highLoad = { rpm >= 3500 && throttle >= 50 }
      enable   = { rpm >= 2000 }

   [Datalog]
      enableWrite = enable    ; Log entries are only written when the variable
                              ; "enable" is true, see it's definition above.

      markOnTrue  = highLoad  ; A datalog marker is written when "highLoad"
                              ; transitions from false to true.  The marker
                              ; looks like "MARK 001 highLoad" to distinguish
                              ; it from the manual markers.

#endif 

Change the #unset AUTOMARK_LOGGING_FEATURES to # set AUTOMARK_LOGGING_FEATURES, and edit the enable conditions (tps/rpm/map/etc.) to your liking.

Datalogging will start when the conditions are met. You still have to start the datalog - Alt+L, <enter>, but it will only record lines when the conditions are met. So you can start the datalog 20 minutes in advance, knowing the lines are not being added until you want.

As noted above, you can also have MegaTune 'mark' the datalog on specific events.

Not to redirect the thread, but I've found using a Palm for logging is really slick. You can velcro it to your thigh or dash and just hit a function button to start and stop. Lots of recording time on the average $20 eBay Palm, too. See here: http://www.msefi.com/forums/viewforum.php?f=73

I use Eric's dash jack connector setup for both the Palm and the laptop. Even slicker. See here: http://not2fast.com/megasquirt/doc/cable.html
Hope that helps in the meantime - I hear Eric has a lot on his plate right now. I'm sure a code mod to allow Spacebar on/off with auto filenaming is doable - just not by me for now.

Wow that's awesome guys thanks - I KNEW there must be a better way to do it. I didn't realize you could get into an old palm that cheap either, that is definitely a viable alternative to the laptop on track.

Thanks !

I use ALT-L ENTER to start and ALT-L ESC to stop.
