Plugged mine in today. Installed some NGK 5992's a few days back gapped at .022. Set mine back to 4 (11 o'clock). Only have 91 around these parts. Car feels great even with only a few miles under its belt. Nice, smooth power delivery.
with 18" hankook v12's in the cold weather I'm burning rubber all day and night 1,2,3 gear. no traction anymore, lol.

I am not but plan to install one of those tools. Flying blind with 93 octane on stock setting. No codes in the on board computer and the car is running great, no weird noises or thumps.
Same for the scangauge II please!
I've since turned mine down to "11" as well since mixing race gas gets real expensive... And all we have in the bay is 91...
It's still a kick in the pants set one back from stock, and still pushes around 17 psi at over boost.
Took a coworker in my car at lunch today who's been in the car several times pre-JB+. As I got on 101 he asked what I had done to the car, because "holy *****, it didn't put me back in the seat like that last time".
So is it seeming like if we only have access to 91 octane it is the smarter thing to turn it down to 11? I just picked mine up yesterday and live in California so it's 91 for me
Terry, I'm running 93 octane with the mods in my signatureAnd the default settings of the jb+. On the highway today with ambient temp around 50 degrees. I did a few 4th gear pulls and with timing set to the gas gauge and the speedo it dropped to 0-1 timing advance on the majority of the the pulls. Could the winterized gas have an effect on this? I didn't get a chance to check a/f while doing the pulls because I just didn't think about it. I'm just worried as I should have zero timing issues because I'm in the he green on all parameters.

Timing will naturally run 0 or even negative at peak torque if the conditions call for it. What you want to see is timing eventually slopping up as you get closer to redline. If it's not then you probably should turn the dial down a bit.

thank you for clarifying. timing does advance as redline approaches. I'm just unfamiliar with monitoring timing and wanted to confirm.

When you refer to the ECU "pulling timing", how would we identify this?
i received mine today, but i got home really late. so i connected it asap and it is sitting in the driveway until the morning..
So far i am impressed with the speedy responses from Terry, and the speedy delivery time..

The easiest things to spot are repeated 3 degree drops at higher RPM and boost values. It can be difficult to distinguish between normal mapping patterns and knock sometimes. It takes a careful eye. But there are also a series of "knock codes" and a check engine light that will come on if you get it to knock bad enough to really worry about it. Long story short unless someone is experienced enough to know what to look for I'd not suggest touching the dial. I'd not suggest touching it anyway, except to lower it, in low grade fuel situations.
