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:

• Support secondary pressure sensor for real time baro readings. This has been asked by various people since (I think) the beginning of the project and is now supported. None of the boards currently have this built-in, but any of the spare analog inputs (Such as the ones on the proto areas) can be used for this. Currently it's limited to being an identical sensor to the primary sensor (ie they have to have the same calibration), but I'll probably change that this month
• There's now a cranking enrichment curve in place of the single value. This allows for temperature dependant changes to cranking pulse widths
• Improved MAP sensor reads (Faster and more accurate) that also allow for negative calibration values. You may notice your MAP sensors readings are a touch higher (2-3kPa at most) with the new firmware, this is normal.
• Some experimental changes to the boost control PID algorithm
• Allow the per tooth timing mode on Dual Wheel triggers
• Fix a bug that prevented dwell limiting from working on Basic Distributor setups
• Fix regression where the tpsDOT value would not reset to 0 (Introduced in June firmware)

As usual, the easiest place to grab the firmware is from the wiki: https://speeduino.com/wiki/images/6/69/Speeduino_Jul17.zip
