Bull Bar Cowboy Posted September 6, 2007 Share Posted September 6, 2007 Ok………. Although the MS forums are very good, they seemed to be aimed mainly at the fast street car / race motors …………. We tend to drive ours a little differently ……… I think that there are enough of us on here now with MS to have decent discussion about issues which relate the use of our trucks. My biggest problem is heatsoak into the IAT sensor …………. it causes the the engine to hunt badly at tickover ………… checking the IAT shows 41C , so I guess its trying to lean it out. Disconnecting the sensor brings me back to an excellent stable idle. Trouble is, that the under bonnet temps of a decent V8 are bloody hot, so avoiding heat soak will be a massive problem. I am considering dispensing with the IAT sensor altogether and just fitting a resistor to make it think the air temp is always 15C – 20C The other issue that has been nagging my poor brain …………….. if the manifold depression is say 45Kpa at idle, then why do we need mapped fuel for 15 or 20 Kpa (some have even rows in there)…….. I can understand putting in may be one row below 45 Kpa (say 30Kpa), but the rest are redundant as the engine will never see those bins. The extras rows would be better used in the higher Kpa range thus almost giving more resolution to the map. So come guys, lets be having some views on these anomalies …………..
