Where the hell did March go?


Another really big month of work, though much of it has been focussed on the hardware side of things so the firmware update this month is a little lighter than normal (Though still a very worthwhile update).


The v0.3.3 board has been finalised and I've sent an order off for a testing batch. If you're brave, the gerbers are included this month. I don't expect problems (And yes, the grounds are connected!) any problems but you never know until you test. There is a dedicated thread for this board (viewtopic.php?f=14&t=452), but in short it improves transient voltage protection slightly whilst also reducing the parts count, simplifying the assembly and reducing the component cost by a whole $1! These changes are all minor, but a good step forward.


The 48-pin Miata board has also been updated to allow the use of the original pins for functions such as O2 and TPS if desired. I've recently been made aware of a variation of this wiring loom for the 1.8L engine and will update the board again shortly to support that as well.


Work continues on the next major board release. I had hoped to have the schematic finalised by the end of March, but I have changed the featureset slightly and will need some more time to work on this.


On the firmware side, the following changes were made:


For those upgrading an existing tune file, please check the following after loading the new ini and firmware:
So that's everything I think. As always, remember to reload the ini file in TunerStudio once you've uploaded the new firmware. If you experience any new bugs with this version, please let me know below.
