[Gmecm] DFCO and EGR elimination

[Rob Handley]

I'm just turning everything off apart from main VE based synchronous BPW 
fuel, based on MAP, MAT and RPM to give me a fighting chance of getting that 
set up right (since I am setting up $58 code for a european N/A 2 litre 4 
cyl engine with manual transmission). I don't have any EGR, IAC, ESC, VSS, 
or narrow band lambda hardware. I plan to tune VE in open loop using a WBO2.

I'll probably turn DFCO back on afterwards, for economy. I'll definitely be 
turning AE/PE back on straight after the VE seems sorted, as that'll be the 
next big thing to tune IMO. I expect to run open loop always.
