[QUOTE="flamefox850, post: 541183, member: 140"] huuhuu sounds like u r very familiar with vtec turbo..and i have 1 noob question here. EK986 : u said that stock b16a map sensor can read boost right ? so what is the voltage ? as what i know, stock 2bar map sensor (most production turbo car) can read until 1bar boost..above that is boost cut ! boost cut only happens when the map sensor read 1bar boost and the voltage signal is 5.0volt (around that la) then the map sensor will send the 5.0volt signal to ecu and boost cut occur. now b16a is an NA engine..suppose to have 1 bar map sensor that dun read boost. u said if we alter the ecu then the ecu will still send signal to injector to squirt fuel when it read boost...yeah i know that. now what about map sensor ? after 0bar, it should be more that 5.0volt signal is it ? what about when u boost ur car to 1bar boost ? what's the signal then ? 10.0volt ??
