What are these magical numbers from this magical thread? Please show link or values? Can't get mine off -21* after sending "Mazda" values.

Doesn't really matter. req_fuel is just a multiplier.
FIC injectors require you to increase the ve table quite significantly anyways (around 60-70%VE at idle) so plug whatever in and just adjust the VE table until youre back to a normal AFR at idle.

I can't speak for DIY, but my assumption is that they are not driving the speedometer with the MS, but simply tapping into the VSS signal which is output by the instrument cluster in order to enable vehicle speed in datalogging and for features that can rely on vehicle speed as a variable. In theory, the MS could be used to drive it, but the way Mazda engineered it makes it potentially a little more of a headache than just intercepting a single signal wire.

Ok, tried 1 like Braineak suggested and it works now. It's violent lol
Then I went to hook up the EBC and here is the error it gives me when I enable boost control:
what the crap is this? I wired it to "boost out" pin R on the back connector, and sourced +12v from the fuse box.

please help.

ITS NOT USED ANYWHERE.
I checked like 10000 times. I will post screen shot.
I'm seriously getting pissed off at this stupid thing.
and it keeps losing settings, like thermistor calibration, had to re-calibrate it today.
And it does not communicate with VSS, because fan wont turn off despite being set to 40mph.
And VSS settings were in there wrong, so it wasn't even working right before I fixed it.
