Economy tune/timing question

[roosterdiesel]

I only have one thing to add...the CP testing equipment needs the addition of knowing when SOI is commanded by the PCM.



My CP setup consists of a 2 channel oscilloscope from SnapOn and a custom pressure transducer from Kavlico. I'm sending them a glowplug and the are making one that will read the same pressures that the cylinder head surface and valves do. I will only test one cylinder with 2 variables consisting of SOI, TDC #1 and cylinder pressure to choose from.


For economy I will test crusing down the highway @ 65mph.
