93 dyno tuneing

[lt1240sx]

in my 240sx im using a painless wiring harness. this thing says it works with only the 93 ecu? wich was fine mecause my engine is a 93 engine so i went and had ion from mad tuner wipe out the vats and essential things for swapping the engine over but now that iv gone with an aftermarket cam and compression ratio i need to be able to tune this thing at the dyno shop. anyone have any idea what you have to do to get someone to dyno tune a 93 ecu???

EDIT:

i have searched and saw there are chip burners, cables, computer programs..... but i dont know what the first thing to tuneing an ecu is about nor do i exactly want to buy tons of crap to flash these piggy back chip things
