Well I don't think there's anything OrBit can do to reveal it. Anyway I just read a few articles about the P3 Polestar S60 with the T43 engine. And while trying to figure out if there are similarities in the tunes (because why would polestar go out of their way to reengineer a whole setup when everything is there.)
I found that "sport mode" in that tune brought on the raised rpm idle etc. When the Polestar tune is purchased, the power output of the T27 (SPA T6) is shocking close to the 367 HP of the T43 (330hp) And the torque is not far off the T43's 345lbsft (325lbsft)
So that got me thinking... Just how close to the official Polestar is the "optimized" tune? And just what's different between the camshafts. Oh shit... I digress..
Anyway... The raised RPM. And other similarities got me thinking... After reading something in an article that says the old polestar actually has launch control but you don't have to do anything to do it. Just two foot launch it I checked it...
Normally I just launch around 2500... I just checked now after remembering how dynamic the torque converter lock up is, and just flatfooted it. It went up to 2500 then stayed for a half second then went up to 3000rpm and the car then started making stuttering noises like launch control. I just recorded it on the JB4 and I'm seeing shifting in timing and the throttle plate moving around and maintaining boost. So, looks like if you flat foot it you do infact activate a launch mode when I'm polestar mode.
