I'm using the system every day now and some things are irritating me a lot! Some of the things are tooling related, others tuning, others the firmware itself.

0) Car setup hate list

  • 26/05/14 IAT heat soaks and is a slow moving plastic one, results in lean running sometimes
  • 26/05/14 Injectors aren't consistent and result in lean running sometimes
  • 26/05/14 Lack of cold idle valve of any type
  • 26/05/14 Lack of keyboard backlight + weight of laptop + more, but it was free, can't complain.

Working on the car aspects in the order that makes sense most. Need to save up for a fancy ultrabook or macbook air with lots of RAM...

1) Firmware hate list

  • 26/05/14 Lack of proper support for coil-follows-input style dwell
  • 26/05/14 Lack of sensor fail over protection
  • 26/05/14 Lack of tip in enrichment
  • 26/05/14 Lack of proper warm up enrichment algorithm 09/04/15 Note, this only affects fuel economy, really. On steep WOT sections it may bog too. No longer have steep sections in commute.
  • 26/05/14 Lack of proper starting fueling setup
  • 09/04/15 Lack of after-start enrichment
  • 09/04/15 Lack of better timed priming function

Have ideas and/or code for all of the above, working on it as fast as I can.

2) Build hate list

  • 26/05/14 Having to build EMSTune from the top dir and run it from core, VERY error prone...
  • 26/05/14 Not having proper versioned apps with my own closed source junk

Firmware build is mint! Java builds are mint. C++ builds are slow, but... :-)

3) Log viewing hate list

  • 26/05/14 Having to manually range-adjust my log traces
  • 26/05/14 Having to select the same shit every time in my log viewer
  • 26/05/14 Not being able to batch-open logs
  • 26/05/14 Lack of proper view/parse arch
  • 26/05/14 Various things that OLV has that ULV does not

On the brighter side, ULV is miles better than OLV in most ways.

4) Tuning hate list

  • 27/05/14 Bad default window sizing and lack of scaling, only scrolling, font size huge, etc
  • 27/05/14 Inability to group, order and manipulate numeric values which are naturally in an annoying order from the fw
  • 27/05/14 No "dark mode" for night tuning, which is the bulk of tuning, all backgrounds dark grey or black, darker mix of colours for tables, etc.
  • 26/05/14 Having to kill EMSTune to get a new log file with metadata in it. EDIT: Seconded! http://issues.freeems.org/view.php?id=934
  • 26/05/14 Not being able to choose a log file name once the above is sorted
  • 26/05/14 Gauges all read wrong, and update too slowly
  • 26/05/14 Having to close 2d tables to see the curve updated, EMSTune again
  • 26/05/14 No tracing in 3d tables, 2d tracing very very wrong
  • 26/05/14 Tunable list popping up over what you're doing after a dialogue!!! :-/
  • 26/05/14 Lack of offline mode in EMSTune, really annoying having to work on the car for offline adjustments
  • 26/05/14 Lack of nice disconnect/connect display, but he's changed this, not tried it yet! Tried it, still not good enough.

I have a fair bit of faith in EMSTune to do the basics to some extent. It's a bit flaky at the moment, but not terrible.

5) Firmware load hate list

  • 26/05/14 Not being able to say "put the latest on the car"

Yep, UltimateLoader is awesome :-D At least one part of my UX is good.

Fred.

If you don't want me replying here, make a comments thread and move this post there.

Any feedback is good feedback, even "it sucks" feedback, if you state WHY it sucks, thanks for that :)


Can you elaborate on these three:

Unable to reproduce this one. OS/Arch/EMSTune Hash/FW hash that does this?

Find me someone that knows stylesheets and I'll teach them how to style Qt apps:

"Numeric data" list, it's in firmware order. I'd like to be able to say "show me these N in this order" and maybe also in a different window "these Y in this order" too. Even if this was hard coded with no UI to manipulate, and I could work with you to come up with some nice lists that you could select from a fake "saved" menu or something.

  • 26/05/14 Gauges all read wrong, and update too slowly
Coolant reading 10C in numeric data showing -10C on the gauge, ego showing random numbers when 0.5 to 1.5 and possibly others less noticable?

From IRC:
Quote:
(18:51:49) Fred: OK mike, tried your change, orange flashing is nice, but i can still edit a table and it takes the edit
(18:51:53) Fred: the messages are nice too
(18:52:13) Fred: i don't like that i get a "silent" and then a "device" one, but i understand why
(18:52:24) Fred: maybe when you see silence, do the device check, and just show the latter?
(18:53:10) Fred: i should be in one of three states:
(18:53:18) Fred: 1) connected, changing shit, having those changes end up in the ECU
(18:53:31) Fred: 2) disconnected, attempting to change shit, finding i can't because there's no connection
(18:53:44) Fred: 3) offline mode, changing shit, but only in the computer and consciously chosen
(18:53:57) Fred: with 3 comes able to send that shit back to an ecu if one is plugged in
(18:54:13) Fred: also, you're burning 100% of one core while offline
(18:54:15) Fred: lol :-)
(18:54:19) Fred: feedback!
(18:54:21) Fred: enjoy.
(18:55:09) Fred: (18:53:31) Fred: 2) disconnected, attempting to change shit, finding i can't because there's no connection
(18:55:09) Fred: maybe just grey the entire fucking lot and don't allow any clicks/anything until it's either offline or online

Your e24696fad42716cd and 9ad63d83d8e0930fae, deb sid and wheezy, fw: all i've tried. hotel has only data and decoder commits. I took screen shots, might upload for you, if you don't believe me :-D

This would require at least some app code knowledge to reselect the table fill colours too.
