Fred's firmware development diary

[Fred]

Making slow progress with the injector testing for the mighty HOTEL, here's the preliminary result:

Want to put an intermediate value in between 6.5 and 8, perhaps 7.25 or maybe just 7. Need to get 9,10,11,12,13,14,14.4,15 too, though. Or at least some of them. A good setup would require ~100 measurements to be made IMO.

And in other news, cyclone lusi is arriving tonight and will be beating the shit out of the hotel and other stuff outside, all weekend. Hence my post. Weekend coding marathon. It's time to teach some lessons. Balls in vice, crushed by my steely resolve.

Coding marathon produced some new functionality in ULV ans some empty cider bottles. Good weekend hiding from the wind-blown rain, then. The new functionality, like that I put in a week ago, will make my life easier bench testing injectors without a full-featured bench test setup in emstudio. Yay for me, then. Tomorrow I'll likely use this new tooling to make some more progress :-) New firmware features coming soon.

[Fred]

Firmware updates done tonight, deleted a bunch of old branches, rebased a bunch more, knocked out some overdue stuff. Feels good! :-)

Did more injector testing, but got spurious results, possibly caused by toluene damaging rubber in regulator. Fail. Going to just through the stuff in and call it a day. Will engineer the next set of injectors I tune properly. These ones served as a good educational tool. It's time to wire up the new ECU and assemble the new manifold and finish/roll out the new firmware code :-) More on this soon.

Jaguar 0.7-alpha RC time! Please review PDFs or kicad files here: viewtopic.php?f=67&t=2429

The more posts we have, and the sooner they show up, the sooner this gets ordered!

Today's a pretty sad day for one story, but a pretty exciting day for a new beginning! Read about it here: viewtopic.php?f=41&t=2430

Turned off the language filter, changed the forum section names back, fixed my avatar, and published the 9+ month old planning thread: viewtopic.php?f=41&t=2190

Many LOLs and ROFLs here at FreeEMS HQ! :-) I have some excellent conversations and messages to clean up and post for your entertainment!

Off to bed now, though.

Announcing three new weekly special events:

• Tuner Tuesday
  
• Circuit Saturday
  
• Website Wednesday

With the rest of the time dedicated to the usual array of chores/tasks/coding/etc.

Tonight and last night I got some firmware work done, great! :-) But I need to split my time amongst the different tasks as I posted about way back then. A different split is required. I'm unsure how to organise it at this point, but I can say this:

TOMORROW IS HARDWARE DAY!

Tomorrow I'll be:

1) Reviewing Jaguar changes
2) Soldering up wires to my Jaguar
3) Possibly reviewing some other stuff for someone

And if I get clear of that, I may work on closing out another issue from the tracker.

This week is in bad shape due to having a bunch of friends in from overseas at the same time. I've not seem some of these people for 5 or so years... So I want to make the most of it before they go away again.

In other news, if you missed the post, or missed the IRC talk, please help test firmware on your vehicles: http://builds.freeems.org/firmware/dev/images/ viewtopic.php?p=38170#p38170

Lots of hardware has been hacked on! :-D Lots of branches have been rebased and deleted and a few commits have been made and some other ones pushed. A great weekend of epic progress, including today, despite some social activity too. Yay! :-) Didn't quite finish the Jag build, but very very close now. Need to wash it and solder the connector up and make a matching loom plug for my hotel. Should be epic. Looking forward to rocking a proper ECU in the hotel, at least for a while. EFI will follow close behind the ECU upgrade, I promise :-)

[Fred]

My 0.6 Jaguar is in use and fully completed including docs! viewtopic.php?f=67&t=2388

Game plan for the car is here: viewtopic.php?f=55&t=1086&p=38253#p38253

Begging for BOM funding can be found here: viewtopic.php?f=41&t=2443

Which includes some firmware work to support the setup that's going on.

Since I last posted:

1) The MIGHTY HOTEL is now EFIed and daily driven! :-D
2) The reddest truck in town has been extracted from storage and is ready for the resurrection! :-D

I still need to tidy up the storage unit more, and get the HOTEL running on code straight out of git (it has tuning in it at the moment that's not in git).

So this coming week will consist of:

0) Jaguar 0.7 (hopefully) final review
1) Getting the hotel setup closer to right
2) Getting the storage unit tidied up
3) Starting to dissect the truck ready for new engine
4) Various firmware tasks
5) Various software tasks
6) Various media tasks
7) Cleaning up the bedroom

The hotel is running pretty nicely already with less than an hour of tuning and tweaking in it, total. It's not right yet, but it's perfectly usable and if not for me revving it harder now, would be getting better economy than before even with the rough tune.
