i finally installed an emanage blue into my car. i don't have the injector or the ignition harness, but i'm having trouble adjusted the map sensor clamping to prevent boost cut at 1bar of boost.
as of now i have the voltage clamped to 4.8v, but can anyone help me with how much lower i can set the voltage to safely without messing with my timing too much?
