Hello everyone!
I have been running the Ly6 in my Sorento for a while now. I was attributing the high RPM power brake up to a possible fuel pressure issue. I now have a fully capable pump and pressure regulator but still have the issue.
It basically falls on it's face above maybe 4k. If I let off the throttle a little it actually feels faster!!
I had been suggested that it was possibly VVT timing related?
A few posts stated they had just set their timing on the big table (high throttle VVT timing table under "AirFlow" tab on HPtuners) to 0 and then 1* at like 2800 smoothed to 12* at 6k. I gave it a shot and it seemed to work better.
However I want to dial this in the right way...
My Ly6 has an Ls3 intake, 90mm DBW throttle body, 4" cold air intake, 1-3/4 primary shorty headers w/v-bands that dump into 3" dual exhaust, stays true dual to a Magnaflow X-Flow muffler which then dumps out the side of the Sorento (3" pipe won't go over the rear axle now that it's lowered 4")
If anyone could make a suggestion or perhaps share their tables? I would very much appreciate it!
I was adjusting the "Intake Camshaft Base Angle". I read this was the tab.... However, I see under "Spark" tab there is a "Variable Cam" area too (VCP Spark).
These pictures are of the tables that were setup by a guy that did a "running/driving" tune for me based on engine and modifications. It wasn't meant to be a performance tune and i have had to make some changes just to get it reliably driveable. These don't show the changes i made while tinkering with things.
