408 cui LS idle issues

Hi all,

I have a fresh 408cui LS running on e38 pcm, i am currently trying to dial in Ve tables as is running SD tune. Engine has a healthy cam installed and i am struggling to get a consistent idle once warmed up. I am still trying to get Ve tables dialed in still rich atm but not having any luck improving idle.

Current thoughts are idle is 2 low at 950 but un sure cam specs are 247/254@ 623tho lift 113LSA. have attached lastest log and tune file.

Any thoughts or help would be greatly appreciated

Cheers

Brad

I can't read the files, but perhaps if you try starting from a higher idle speed to get it stable, then try dropping it from there?

I assume you've done the basic checks for the software reflecting the hardware, wiring, vacuum leaks, etc?

Gord,

Had another play today at 1000 rpm seems a lot more stable I underestimate idle speed required for cam. It's sitting around the 70kpa at idle as has decent overlap.

All basic checks where done.

Cheers for the reply
