The first part to understand is what this stuff about ZCS/VO or 'vehicle order' is. I am only going to elaborate on coding individual parameters, you can go learn how to code entire modules thru the VO later once you learn the basics below. On Pre '02 cars the coding is slighly different method than Post '02 cars. Please read it fully if you want to understand, this isnt exactly a quick cheat sheet guide. Im serious!ĭUMMIES GUIDE TO UNDERSTANDING NCS AND CODING I am not responsible for you blowing up your car or damaging your modules. Proceed at your own risk, this is just my interpretation for educational/entertainment value only. If I said anything wrong, experts please chime in and correct me. Im just trying to chew, regurgitate it for the 'dumb' masses like myself who are still learning. I didnt come up with this stuff, the experts out there did. So this is why i wrote this post, to help understand what ncs is doing. I like to understand what im doing and whats going on. I found lots of guides that just shows you what buttons to press or ones that are too complicated for a layman (not a programmer) to really understand. I was helping another person, but i thought this info might help others out there trying to make sense of ncs expert.
