black-ibex Posted May 24, 2010 Share Posted May 24, 2010 Hi, From Nanocom data: AMBIENT PRESSURE(Kpa) – This value must be 100Kpa at the sea level and decrease when the ground height increases. A decreasing of that value related to the acceleration should indicate that the air beyond the filter is less than required. MANIFOLD TURBO PRESSURE(Kpa) – at idle speed must be equal to the ambient pressure 100Kpa and it goes up to 210 (Defender) or 230 (Discovery) at engine maximum load Hope this helps.
