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’m using D585 coils
Injector size - LGSEC EQU
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
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.
