Yes (see link below)
Usually not - normally it does not need to be calibrated again. You can check the threads on here for confirmation (see link below)
Not sure I understand your question, but it wasn't pulled, it was ordered new from my local Lexus dealer, then calibrated there once installed.

2011 - 2012 (see post #2)
"Lexus tweaked the ECU throughout the years (08-10 part number 89650-53040, 11-12 pn 89650-53041, and 13-14 89650-53042). Not sure what entirely changed through the years, but the most sought after ones are obviously the newest ones (11+) which would benefit older IS-F's. As for us 250/350 owners, many of the people here did it and thought it was one of the best things they've done for their handling. If you buy a used ECU, you most likely won't have to calibrate it..."

Just an FYI for those you considering purchasing these, you don't usually need to have them recalibrated if they've already been calibrated in the past (which the OP said he bought his brand new and had it calibrated). Only brand new ones absolutely need it, unless you prefer just to drive with no power steering. Of course, it's best to just have it calibrated to your specific car, but if you don't do so, it'll work fine nonetheless (I had mine redone when I bought mine, didn't notice a difference at all).
I'm assuming since he bought it new recently, it'll most likely be the newest 42 unit (especially at the price he paid), but I wouldn't rule out a 41 unit, doubt it's a 40 unit. OP will want to confirm the part number that's on the ECU for those who are asking for it (and needs to post a asking price due to the forum rule for this section, unless I'm blind and missed it)

Haha, I thought I recognized my writing when I skimmed through here.

Sorry guys, it has been sold already. I have edited my ad to reflect that, but maybe it has not refreshed for everyone...
