[QUOTE="jinkl, post: 3371024, member: 3008"] u must understand the basics first wht calculate the amount of air is the airflow sensor wht commands the injectors to open up is ur ecu so lets say u r flowing an amount of air, lets jst say 50cfm la kay, the flow in calculated in hz the airflow reads it and passes it to ur ecu at the mapping in ur ecu, it says 50cfm of air , 4000rpm , open the injectors for 20ms so how now, u r using vr4 car n stuff bt evo ecu, bt 450cc injectors vr4, 20ms of fuel enuff ? will it give a lean output or rich output how if we change the whole scenario to another one, this time , vr4 hafcut , evo ecu, evo wiring , evo air flow , evo injectors, now at 50cfm of air , 4000rpm , ur injector open the evo injectors nice at 20ms , fueling ngam, but jeng jeng jeng , ignition timing for evo n vr4 is diffrent , evo is high compression which has lesser ignition timing, so how now ? u r running vr4 engine but ur evo ecu is giving low ignition, kantoi :P so , the better way, change to a newer ecu , wiring and airflow is the minimal , make sure change in a set la, then the next is rechip or piggyback to fine tune it\ like the b8 180 and b8 210 pulak if u put a b8 210 ecu in ur b8 180 , even the turbo flow amount is diffrent, mapping is all diffrent supposedly la , u still need piggyback or chip to fine tune it [/QUOTE]
