[Gmecm] On the fly tuning

[Darren Freed]

So I'm one step closer to on the fly tuning with a GM OBDII pcm.  I've 
added an additional 16k sram and am able to write to it and read from it 
with SCI(ALDL) type comms - ie modify tables on the fly.  This is 
similar to what is done with the efi332 project.

Someone mentioned the capability of GM pcms vs the aftermarket - I 
totally agree that GM pcms have _way_ more capability than anything in 
the aftermarket.  With Steve Ravet's VPW interface, a little daughter 
board off the edge connector and a little code tweaking, we can have on 
the fly tuning with all the stock GM pcm capability.  This could be 
applied to any 96-98 4 cyl, v6 or v8 pcm.  I'm not sure about later 
years, since it appears they dropped the edge connecter with newer pcms.

Now I need a nice little GUI in which to do the .bin editing...
