Wowsers, what a month it's been! September has seen probably the heaviest development I've put into Speeduino for quite a while and I'm really happy to be able to say that there has been a few really nice things come out of this work.

As usual, here's a list of the major things that were done in the last month:

• The new custom PWM system! This is really terrific and was a huge piece of work. It means that the PWM outputs (Idle, boost and VVT) can operate on any pin we like (Not fixed to the PWM pins listed on the Arduino specs) and at any (within sensible limits) frequency. The timing remains in hardware, so overhead is quite small (Though the 2 new 3D maps for boost and VVT do have a slight impact). This should mean that most PWM valves are able to run directly and smoothly.
• I finished off my old dual VR / Opto conditioner board. Best of luck to any brave soul who wants to try this out
• Added full calibration ability for MAP sensors. No longer are MAP inputs limited to the MPX4250, but now basically any 0-5v type sensor can be used.
• Dwell is now added as an output channel for logging / display
• Fixed a bug that was increasing the skip revolutions by 1 (Ever so slightly faster starts now)
• Further work on the 'smart' decoder filters. This is still very much a work in progress
• New dual wheel decoder added
• Dwell limited can now be turned off
• High speed tooth history logger now a more reliable (Some further work to come here, issues remain for low resolution triggers at low RPM)

Next, just a couple of things around the project itself. As a few people have asked for it, I have setup a Patreon page for Speeduinoin case anyone wants to support the project in this way. I am not going to push or put on a hard sell or anything like that, but the reality is that there is always test boards to print and slowly but surely better test equipment that I'm acquiring that help make things a lot easier and faster for development.

FINALLY, I've made a new video showing the latest features in the firmware! Feel free to check it out and share it with anyone you think might be interested: https://www.youtube.com/watch?v=NVwM_OJ8Z4g
