Fingers crossed!

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!

Definitely idles much better now... time will tell if the KAM doesn't reset while driving... it's a 21 mile drive door to door from my buddies shop... almost home... so far so good...

Curious... is the stick battery only 650CCA? That is what was in mine... I went ahead and put in the 850CCA.. I figured with the alky pump in there it wouldn't hurt to get a stronger battery.

Been hammering on it today trying to replicate the OAR/Knock issue. Seems to be gone... amazes me how sensitive these components are to voltage deltas.. Honestly, if I was monitoring my car like I do with my SCT programmer, probably wouldn't have noticed it much till I went to the track...loosing 12+ degrees of spark is however pretty noticeable...

Do you have a log or just watching handheld?

It was happening randomly, so I never was able to get a log... but the hand held has min/max and nothing looked out of line? It wasn't like there was a massive KR event and the car went into limp mode per se... I WAS initially worried that something let loose and the ECU could't read the timing correctly so it disabled the knock sensors and reset OAR!  HOWEVER, I noticed my LTFT's were also reset back to 1 for all loads.. so it made more sense that something was resetting the KAM.. just didn't suspect the battery until I posted on here...

Another interesting thing was that in lugging situations (I live at the base of the mountains so its EXTREMELY hilly where I live) at 50+ mph (or 6th gear)  it felt like the car was struggling a bit.. however, with the new battery that seems to have abated as well... dunno.. could be placebo but the car is running A LOT better..

Freaking weird... happened again.. car is running better.. not sure why my OAR keeps resetting... battery obviously needed to be replaced...

at this point I believe I am chasing an electric issue..
