Hi All. I have a Proton Persona with a slight problem. When cold, the speedometer reads approx double what it should. All OK when warmed up. Any ideas please
I got my power fc d-jetro recently,it come with ecu,hand controller n map sensor.But i saw some1 selling the same ecu come along with a air tempreture sensor,so i confused am i missed out that air tempreture sensor?
