You're right, CL is centerline.
There's two basic concepts, Lobe Separation Angle and cam advance.
In the DOHC world people tend to view the intake and exhaust cam as being independent, but they...

Here's what I found in my analysis. These are actual degrees, I'm not sure what you need to program.

The low speed cam setting results in 17.8 in-hg of vacuum, GM usually specs 20 in-hg. If you...

I'll work with 0.440", that's 1.7x so it makes sense...

oh crap, the MACE cams only have 0.4252" lift?
I assumed they must have increased the lift closer to 0.5" and back calculated a 1.9 ratio. I'll go back through the exercise with 1.65.
With the...

Okay, I have my computer back up and running now. Reviewing the cam card I see 0.25669" cam lift, but what is the cam follower ratio?
ie: what's the valve lift at 0.25669" cam lift

From the...

I figured it out.
By taking the calculated V8 cylinder air mass and dividing by the actual cylinder air mass and then filtering greater or less than 0.6 I was able to divide out V8 and V4 data into...

yea, for some reason my username is my email and I can't change it. thanks!

If you could send me the shop manual that would be great.
Otherwise I'd need: int/exh valve diameter, compression ratio, bore diameter, stroke, rod length, OEM HP/TQ (dyno plot even better)....

Does this engine use the same VVE concepts as the Gen 5 V8?

I've got a 2016 LFX in a canyon with the same aftermarket tune. I'm here with ya.
Haven't started re-tuning mine yet, working on two other motors right now.
I have the Performance Trends software...

I'm trying to tune an L83 in V8 and V4 mode, but I haven't been able to figure out how conditionally filter my logs in VCM Scanner.
I do see the "Displacement on Demand Requested" variable, and I'm...

I just bought HPtuners and tried to read the ECM of my 2016 Silverado 1500 with L83 and I get an error, see attached.
According to the HP tuners site I shouldn't have to send the computer in for...

If you still have the misfire, try gapping down the plugs, if the ceramics aren't tan/white I'd go a heat range warmer.

I'm looking to tune my Gen V L83 Silverado and find the Tow/Haul mode transmission shift points to be confusing, look at the attached screenshot. I would think Tow/Haul mode would pull shift upshift...

From an engine performance perspective +10 / -10 cam degrees is enough for any engine, the OEM maps go beyond this range for emissions reasons, not performance.
