man i couldnt disagree with you more. in the end both products do similar functions but the guys with pgmfi went through all the reverse engineering of the maps, memory addresses etc and then developed their own software. its hardly copying except in the overall purpose. infact the pgmfi guys helped to drive DOWN price of hondata and other EMS. check out pgmfi and read. plus its not like crome popped up one day, its been an evolution of software over YEARS and multiple editors.
