Just a quick update that I've (at this 11th hour) finally finished off the project video for the 2017 Prize, of which Speeduino is a finalist!
It briefly runs through the history and motivation for the project as well as where it's going in the future.
A little late this month due to a few bugs that have taken quite a lot of time to resolve, but the September firmware is now ready to go. The bugs were in relation to the comms system, which underwent a major rewrite this month to not only improve the stability of connections, but also make the tune transfers significantly faster. I know a few people experienced some comms issues with the August release and that prompted me to not only fix those issues, but make some major improvements at the same time.
I've also made a lot of small improvements that are specific to the MX5 / Miata plug and play unit (and MX5s in general). I know this doesn't necessarily benefit everyone, but I do want to make sure these are working really nicely before the units go into wider production beyond just the Beta units.
The full list of user facing changes is below:
Note: The changes to the comms code required the internal memory layout to be adjusted. The system should update itself when it starts for the first time with the new firmware, but PLEASE CONNECT TO TUNERSTUDIO AFTER UPGRADING TO ENSURE THAT YOUR TUNE REMAINS CORRECT!
The firmware bundle can be grabbed from: https://speeduino.com/wiki/images/1/19/Speeduino-Sep17.zip
As always, if there are any issues found with this firmware, please leave a reply in this thread.
So time for some more new firmware goodness! This month sees a return to the more standard feature / bug release type changes rather than the larger structural ones I've been working on the last 2 months. I've gone back over the feature request list and tried to get through as many of them as I could, including a few that have been requested fairly regularly for a while now.
On the hardware front, I am really excited to say that the beta run of the NA6 MX5 / Miata PNP units is done and (mostly) shipped. These have been in the works for a long time and, whilst some development is still required on the firmware side of things for them to be perfect, they are ready for wider testing and use:
The major changes on the firmware front this month were:
As usual, the easiest place to grab the firmware is from the wiki: https://speeduino.com/wiki/images/6/69/Speeduino_Jul17.zip
Another month, another firmware drop! As is usually the case, there has been a bit of behind the scenes work happening in the firmware that is designed to both increase general stability as well as preparing for some more core changes that are coming in the next month or two.
There's also been a heap more work on the manual, in particular the layout and formatting of the offline manual. The whole thing is considerably easier to read and things like images are sized correctly etc. As always, if anyone is interested in helping out with the documentation, just let me know
As a bit of a side effort, I've begun work to bring the whole Speeduino codebase into compliance with the MISRA C:2012 standard. The MISRA standard is a set of coding guidelines designed by the automotive industry to maximise reliability and safety in software used in vehicle systems.
About half the code is now compliant and I expect to complete this effort within the next few weeks.
So as far as the new firmware goodness goes, the main changes are below:
Where does the time go? April already and March has been another big one for Speeduino. Forum users and installs are increasing all the time and it's terrific to see the project starting to be mentioned more often on forums etc as a truly viable system!
As a heads up, I plan a slightly quieter month throughout April on the firmware front. I will still be doing general maintenance, bug fixes etc, but probably not so much work on new features. The reason for this is that I want to spend a good chunk of time working through the documentation pages (https://speeduino.com/wiki/index.php) to try and:
1) Have at least something on every topic
2) Cover all of the most used pages with good detail, images etc
DIY Engine Management Systems live and die by their documentation and to date whilst Speeduino's documentation has been minimally OK, I would like to bring this up to a much more professional level. I've already begun restructuring a few things, so there are many placeholders there currently as indicators of what I will be adding.
If there is anything you find that you believe is important, but that doesn't already have even a blank page, then please drop a note in the forum and I will look at adding it.
Additionally, I am ALWAYS on the lookout for anyone who wants to help with documentation! If you have some time and knowledge to share, please do contact me and I can get you the required access!
As for the full feature list from March, here are the primary changes:
The firmware bundle can be downloaded from: http://speeduino.com/wiki/images/2/24/Speeduino_Mar17.zip
As usual, make sure to reload the latest ini into your TunerStudio project after upgrading the firmware
So after the big release of sequential control in October, Novembers release is less focussed on features and more on under the hood changes, although there have been a few new functions added
For the most part though, November is a stability and bug fix release, with heaps of patches included. Many of these are around sequential (and a big thanks goes out to Dan Elliot for testing throughout November!) but there were also improvements made to a number of decoders, overdwell protection etc.
As far as new features go however, the big one is that flex fuel sensing and adjustment is now supported. This allows for reading from a standard frequency based flex fuel sensor and adjusting the mixture accordingly. The great thing about the standard GM/Continental sensor is that is requires no calibration and so tuning of fuel requirements is largely universal. The default settings included in the base tune will work in almost all cases.
This feature does need some documentation to be written up, which I'll do over the next few weeks, but the support is there and working from this month onwards.
Finally, many of you will have seen that there is a poll up to vote on a new logo concept. Just incase getting to have a say in the new logo isn't enough incentive (how could it not be!?!) I've decided to add an extra reason to vote....
Once voting closes on Dec 16th, the final logo will be put together based on the results. At that point I'll be choosing 1 person who voted, at random and they will receive a t-shirt and bumper sticker with the new logo from the first round to get printed! This competition is open to all users who have made at least 1 post on the forum at the time voting closes.
Note that the shirts and stickers will take a few weeks to get printed once things are final, so don't expect your winnings before Christmas or anything.
There have been a couple of additions to the voting options recently and everyone can adjust their vote right up to the 16th, so even if you've already voted, take another look and have your say! https://speeduino.com/forum/viewtopic.php?f=28&t=890
The firm is available for download in the usual locations:
Github release: https://github.com/noisymime/speeduino/releases/tag/201611
The full list of changes included in this months firmware is below:
OK so I'm a bit late with this months update, but there's a good reason for it. I know I've been a little quiet around the forums the last few weeks, and this has mostly been due to putting all of my Speeduino time into the firmware.
So, without beating around the bush. The good news is that the October firmware now supports full sequential fuel and ignition control! This has been a huge piece of work to get in and is one of the reasons things are a little delayed. A couple of points about the implementation:
The firmware is available for download from the usual locations:
Monthly code dump: http://speeduino.com/wiki/images/8/87/Speeduino_Oct16.zip
Github release: https://github.com/noisymime/speeduino/releases/tag/201610
As a side note, there are issues with the 126.96.36.199 and 3.0.11 versions of Tuner Studio that cause corruption to your tune file! Version 3.0.12 fixes these, but PLEASE avoid the bad versions as they can really mess up your tune very quickly.
So September has been largely focussed on hardware for me, but as always there's been some more solid improvements and new features added in the firmware.
On the hardware front, I've finally had a bit more time to play with the new surface mount design, specifically the MX5 PNP board that has been in the works for a little while. Here's a little preview of the current incarnation:
This board is not yet ready to go and there were some showstopper issues found on this testing version, but given the ground up design, this was expected. The board did run an engine, but a few of the onboard features are not functional due to design issues. Still, it's getting there
Around the firmware, it's been fantastic to see a few people putting forward pull requests for their own work. I will need to begin putting in place some processes to make this smoother in the future (Eg a style guide) but I'm thrilled that others are putting up good quality pull requests that I am confident in bringing into the main code.
As usual, here's the list of major changes:
This firmware can be downloaded from: http://speeduino.com/wiki/images/a/a1/Speeduino_Sep16b.zip
Or from the release on github: https://github.com/noisymime/speeduino/releases/tag/201609
Despite me being largely out of action due to other commitments that last 10 days or so, there was a lot of progress made throughout July. Some of these things are parts of larger pieces of work and aren't fully completed yet (Eg 5 cylinder support), so this update may look somewhat lite on for new features, but rest assured there's lots happening.
To keep things short and sweet, here's the list of the major changes since last month:
As always, the firmware is available from the wiki: http://speeduino.com/wiki/images/2/2f/Speeduino_Jul16.zip
Or now also as a release on github: https://github.com/noisymime/speeduino/releases
<Insert usual spiel about me not being able to believe it's the end of June already>
OK, short, sweet and to the point on the update this month. So much good stuff happening, but at least for June the firmware is a little quiet on the new features front. That's not to say it hasn't got a lot in it though!
On the juice side of things, a lot of work has been done on the Flex fuel capability. Whilst it's not fully ready for June, the ability to read, display and log a flex sensor has been added. classified has done a heap of work on the actual fuel/ignition adjustments side of things and I'm hoping this should be merged within July sometime.
A LOT of work has gone into squashing bugs that were identified, some small, some more significant. I'm happy to say that from a reliability point of view, this release is the best to date by a long margin so I recommend upgrading for this alone.
Rather than drag it out, here's a full summary listing of the changes:
As usual, the release is available on the wiki: http://speeduino.com/wiki/images/3/36/Speeduino_Jun16.zip
I have also begun tagging releases on github to allow easier tracking through there.
