L94 vvt

[reddevil96]

I have been playing around with the VVT tables and I am definitely seeing improvement, but I would like some input weather or not I am taking this to far. This is a 2010 Escalade L94 6.2l (VVT and DOD), from what I read this is the same cam that is in the L99 equipped Camaro's so roughly .500/.492 198*/201* and unknown LSA and ICL, and I also do not know how many degrees the cam actuator is advanced in the park position. I am only guessing that it is roughly 8* advanced in park position based on what I have been reading.

also I am using 2.25 beta on this file and have found that 2.24 will not open it

Nobody ?

when you say improvement, is this on the dyno? which i think is your best bet to dial in the VVT. FYI higher numbers mean more retard and not advance

I've modified my VVT tables based on some old school dyno graphs. The graphs showed power with a 4* advanced cam vs a 4* retarded cam. The graphs crossed around 4000rpm with the advanced cam stronger below 4000 and the retarded cam stronger above 4000. I was told the VVT cam in my truck has 6* advance built in, so I retarded in 1* increments beginning at 3200 until I had 6* retard at 6200. That gives a smooth transition from full advance to full retard and, theoretically, should give the best power throughout the rpm range.

Your table shows a massive swing from advance to retard at one rpm level. I'm no expert, but I don't think that's the best approach.

I wish I had access to a dyno, and hence I would probably not be asking my question. what I am currently running in it now is only retarded by about 3-4 degrees max, and it feels stronger above 4k rpms.
