Pretty much any time I'm in a 25 mph zone that goes to 35.....I punch it .

I can't resist the 2-1 downshift at 25, its like SHO heroin.

I wonder if these are all the reasons for my rears wearing faster than my fronts?
Love it...i like watching the rear power gauge for this also!!!
Wish I had an awd gauge.....

As sensitive as the knock sensors are on these motors, it is a fairly common occurrence to see knock when you let off the throttle. There seems to be noise created from the TB closing.

As far as power going away in repeated runs, the tuning has safe guards based on IAT, coolant temp, cat temp, valve temp, flange temp, EGO temp...well, you get the idea... ;)

I am not disputing this at all but just want to learn.  Why would there be spark knock in a closed throttle situation with no load on the engine?  Are you saying that the sensor "hears" the TB close and "thinks" that noise is spark knock???

I just cannot get my head around having spark knock and needing to pull timing when the throttle is closed and there is no engine load.  I understand that these engines do cut off the fuel in a no throttle coast condition but I don't think that happens immediately after an abrupt lift.  Does that have anything to do with it?   I would love an explanation for this.

X2 on the above!  Any insight greatly appreciated :)

If tuned:  Take note of the strategy code as you return to stock (including 3 bar MAP to 2 bar MAP) -> take car in & get it serviced -> check strategy code when you get car back -> have tuner update your tune if the strategy code has changed -> reload tune -> ENJOY!

What equation is everyone using on torque? I switched to the most current, and immediately started seeing +7 as my max. Before the switch I was seeing +4 as the high.

This is getting interesting. Now I'm not the only one getting a +7. I am using the most current equation. I got the +7 running 4X (3BAR). Running the 2BAR 4+ tune I got a max of +2. I flashed to stock last night but don't have any knock retard numbers yet on the stock tune.

Glock-coma has an Unleashed tune so his tuning parameters are probably somewhat different than ours.  However, it is interesting about the change based on the equation. 

Still, the difference in knock retard between your 4+ and 4X tunes when you used the same equation is a bit concerning.

Boost levels when you see that KR?  LME requires a 160 TStat with the 4X for a reason (increased heat with increased boost), as explained by JT a short while ago.  I am guessing the same "issue" with Torrie's tune.  Also are you both VTA for the BOV?

Very good question about the boost levels they see when the KR is +7.  Interestly, when I am WOT and highest boost, I never get KR.  The only time I get the +2 is at a low RPM lugging condition and relatively low boost level.  I have tried it when the car is not fully warmed up (150* or so) and fully warmed up (180*) and the KR on mine is the same either way. 

Note that I am NOT disputing JT at all - but I am just thinking there is more to the high KR readings than just boost and temp.

I have not done the VTA so far and I'm running a 170 T-stat. Coolant temps usually hang in the low 180's regardless of the ambient. As Bruce points out, it is important to note that all else staying the same when I went to the old 4+ 2BAR I went from 7 to 2 positive knock retard.

I'm still running the stock tstat and I am VTA.
I've seen the +7 when the temp was  175*  don' t really see it below that.
It only happens lugging in 6th gear. If I downshift it immediately goes to a  lower+ number or -

I have never generated high boost levels. My max highest ever was 14.1. Mostly I'm in the 13's. (With 4X) I do not get high KR when I'm at WOT. That's usually 0 reading. Don't know yet if it's at lift off from WOT, or at lugging.

Well I am going to the track for sure on Friday. I'll be logging my runs. I'll be keeping an eye on the KR and report my findings.
