I use a PICkit 3 programmer which I imagine are about $50USD.
This plugs into the 6 way (from memory) headers along side of each of =
the pic processors.

So if you needed to change parameters, you would for example edit the =
various parameters in the .asm file -
	Engine type - ENG EQU which for my Renesis engine is 0xA8
	Coil Dwell - LS2COIL EQU which I=E2=80=99m using D585 coils
	Injector size - LGSEC EQU=20
	Wide or narrow band O2 - WIDEBAND EQU
	Turbo - TURBO EQU

You then need to get the config right for the processors. For the EC2 it =
was:

	Osc                             EC OSC2 as RA6
	Osc Sw                       Disabled
	Pwr Up timer              Enabled
	Brown out                   Enabled
	Brown out V.               2.7V
	WDT                            Enabled
	WDT Postscale          1:256
	CCP2 MUX                 RC1
	MCLR Enable            MCLR Disabled  RG5 Enable
	Stack Ovf                    Enabled
	LV Program                Disabled
	All other protects  Except Config Write Protect       Disabled=20=


=09
Then you would run your assembler and linker creating your executable.

Then program chips.

Best if you can to get someone familiar with the environment to help you =
through.

Cheers
