Stock idle speed for an evo III is : 872RPM ( 109("6D") x 8= 872)!!!
This is the base idle speed! At cold temps the ECU will push the engine
up to the value "B3" or "179x8=1432RPMS" so if you wanna bump the idle speed
ex:+200rpm you need to modify all 8 values.

1AFE: BD BC 4A JSR LBC4A
1B01: C6 80 LDAB #$0080
"3E" hex= "62"dec
31050 divided by 62= 500! thus stock evo III GSR are 500cc INJ AKA yellow top!
To modify this value simply divide 31050 to "X"(new inj size) and you will
get the "Y" dec value. Then convert the "Y" value to hex and replace with that
byte 01AFD( stock value "3E")! Then go ahead and BOOST!
ATTENTION: SOME U.K spec EVO III GSR came equipped with 540cc, and
585cc injectors and you might find different values for the byte 01AFD.

I think I did most of the work, so here it is ENJOY!
I will be modding an old project program that will do all the work for
you with a graphical interface! SO keep posted...
