05 Acert Idle RPM??

An engine can burn from .7 gal to 1.5 gal of fuel per hour while the engine is idling. Excessive idling can cause carbon buildup and/or excessive idling can cause the engine to slobber.If extended idle time is required, control the engine rpm to 1000 rpm or above 1000 rpm. Ensure that the coolant temperature exceeds 180°

 

800 RPM is best for acert fuel flow is 0.28 gph and + 30 psi oil pressure to circulate everywhere tubid etc and 170° water tell 2%engine load ... With A/C on and can on 4% load and .48gph fuel.
I tried 750 and 850 etc thats not stable , on other lower or higher rpms gph flow and diesel consumption is more . So i go by 800 on ecm that is 815rpm
