Open Source PNP M52/S52 OBD2 Tuning Board ECU - speediuno M52

[RobertFontaine]

I'm pretty excited about this little project.
Open Source, extensible, proven, cheap.
For Turbo applications its supports both MAP and Wideband Sensors.
Plug and play with the M42.1 ECU.

Did I say cheap.

Over the years I have learned how to tune the OEM ECU with RomRaider ( but it's MAF based so super fussy even if you upscale, add a resistor or use a larger MAF)
I've Looked at VEMS, Megasquirt, and the expensive commercial solutions.

I don't see anything missing from this and if I find a feature I want to add it's possible to do so pretty damn cheaply and there is decent community support for Speediuno and it look to come in at less than a third the price of the next cheapest solution. Other stuff in there (option for hall effect cam sensor, external barometric pressure, sequential injection w/ the 32 bit mcu)

Can't find a downside....

If someone has some negatives to throw at me before I dive into having some PCBs made for me I'd appreciate your insight.
