Ah ok, mine was built 7/20 but I’ve heard of people with 7/20 getting lucky… I’ll look it up.You can start by checking the driver’s door jam. If the car was built before 6/20 then obviously the ECU was too so you can stop looking. If not, you’ll have to pull the ECU to look at the sticker on the side of it (there are plenty of how-to videos online, it takes about 5 min).
My car was built 3/20 and the ECU was from 2/20, so I think there’s a decent chance yours is tunable. Definitely worth pulling the ECU to check.Ah ok, mine was built 7/20 but I’ve heard of people with 7/20 getting lucky… I’ll look it up.
thank you!
wow congrats on the ?I bought her! Lol. Well, technically yesterday. Just finished the 14.5 hour drive home. First thing I did when getting home was check the ECU date. 5-25-20…does this mean I made the cutoff to be able to tune? Can’t wait to get started!
A tunable 2021 A91? Holy smokes that’s the golden unicorn of all unicorns!!I bought her! Lol. Well, technically yesterday. Just finished the 14.5 hour drive home.

As a follow-up, Sto N Sho once again saves the day.Switched from old tow hook mount to sto n' sho mount. I like the centered look a lot better, and has quick release so easy to put on and off. Might just keep the plate detached in the back, and only put it on when doing longer drives with more freeway.

My only concern is if I accidently touch a curb stop, its going to be even worse since this loses about 1/2 inch of clearance. However, I already have to try to be careful anyways even without it, so not really too big of a deal.
it’ll need a bench unlock then it’ll be tuneable. Tuners should have the capability to bench unlock then custom tune.So if you have a tuneable 21, do you have to send it out to get tuned?
You have a few options, go to a local tune shop and they can bench unlock and then a custom or off the shelf tune.So if you have a tuneable 21, do you have to send it out to get tuned?
It needs a bench unlock, like late model 2020s do, but if you don't want to ship the ECU out to get unlocked you can get it remote unlocked where the tuner sends you the necessary equipment and remotes into your computer to do it (that's what I did).So if you have a tuneable 21, do you have to send it out to get tuned?
Did you love tap it with the sto n sho?? I'd imagine having that happen is still pretty bad due to the pressure / torque put on the splitter from the bolt. Although still way better than scraping up / cracking the splitter itself.As a follow-up, Sto N Sho once again saves the day.

No tap. I have tapped my aluminum garage door (long story). No issues at all. Can't say the same for my garage door with 2 little dimples about 6in from the ground.Did you love tap it with the sto n sho??

I often find myself stopping hilarious far from the parking curb, like 3 feet sometimes. The car isn't that long though so its usually fine where I live as most parking spots are decent sized. I still stick out of the spot way less than the giant ass Tundra or Suburban parked next to me.
