    Thoughts on Ilde

    I only get a short time when I'm home to mess with my C7/M7 but would like some criticism on the idle i have. This has LTH large cam and YSi-V7,head work. I see that the trims look good, Starts and falls into idle without surging, Timing looks ok but would like a pro to look at it in general.



    Thanks.

    seems like your High pressure pump is a lttle lower than normal

    as you can see its requesting 400-500 psi but only seeing about half

    could be issue with the install and the lash clearance

    Never realized that, it keeps up during high pressure demand. There is no lash, It's just 10% over lobe. Was told and read at 10% you don't need a lash cap, but that was 2-3 years ago. Only thing I did was re-span the columns per the Banish DVD. Wouldn't think that would matter.

    This is because of his "fuel rail pressure relative" and/or "fuel pressure estimated pids. It's logging 0 so in the charts he's getting the average between actual and 0. Just remove that pid.
