2011 GT500 TVS tune analysis

[RedVenom48]

I swear on my life I found a discussion going where Jon Lund Jr was defending his position about how much extra time it took to tune a JLT intake versus others. I cant remember where I read it, but it was a good back and forth between Lund and Jay Tucker of JLT.

Seeing that and watching reviews of the PMAS and how it compares to the JLT, Whipple and Ford Racing intakes (Similar to the Whipple and Ford Racing) is what prompted me to spend the cash and buy the PMAS.

So with their tune there should be zero knock, even with 91 octane in the tank and the current 91 octane tune loaded.

I can understand why they are taking a safer route.

Thanks for the info fullboogie!

VMP is partnered with Roush Performance. Have to make tunes that wont compromise that relationship (emissions, safety of the tune).

Real interested to see that discussion if you can find it.

Sorry for the stealth edit, but after typing that I realized it probably doesn't apply to you. I've got an '07 with no knock sensors, which is why (per BJ) VMP has backed off a tad on the timing on my newest tune. After reading my response, I decided to edit since we're talking two different scenarios. Sorry bud!

Without knock sensors it's best to have less aggressive tunes for sure.

This is true. I don’t know where you saw that, I’ve never seen it discussed publicly, but he personally told me as much last year in a ticket request.

OK will do. Any idea where the knock is coming from? Exhaust looks good, no rubbing anywhere. Also the same amount of knock behavior is present whether I put 100 or 91 in with the current 91 tune lol

Hiya. I got another 2011 GT500 here in Arizona too. I have Knock sensor acting up on my datalog too, though I can't hear any pinging (not that I'm an expert at that).
Did you ever find out what the problem was?

Check your plugs for detonation

or

J&S Vampire Individual Cylinder Knock Control System

Beautiful product. Far more advanced circuitry than the factory sensor circuit with the ability to identify the knocking cylinder(s) and retard timing on only those cylinders.

What plugs are you running? I'm running NGK BR7FE plugs gapped at .28, no knock issues at all.

 

[2000bluegt]

These, per VMP: Brisk GR12YS.
Brisk Racing Spark Plugs GR12YS Silver (replaces T
Gapped at 0.28

I have a VMP Gen-1 blower.

You are in AZ too huh? Phoenix area?

BJ probably won't see this unless you ping him @VNMOUS1. But unless you dropped that spark plug in the dirt before your photo, those specs could surely be signs of detonation. It's also running pretty rich.
