A91 & Recent 2021 Impossible to Tune / ECU manufactured after 2020/6 is locked? [WARNING: NO POLITICS]

[Dooo]

Southeast Toyota dealer inventory moves through the Jax FL port facility.

Sounds like FL port has their shit figured out compared to NJ... Is the hold due to the Carbon spoiler or is there something else wrong with them?

I wouldn't say that:/ They've (FL) been struggling more than I've ever seen with inventory schedules. It's been difficult for us and our customers. I was told the spoiler was the issue. However, after reading some posts on here about how the july and later builds have a newer software that has yet to able to be unlocked to be flashed....I'm wondering if that is a piece of the ship hold also.

Yeah this is frustrating for sure! Two years in a row Toyota screw up the launch of special edition Supra... Ar least you are in the warmer part of the country year round. Without any ETA I am getting inru the winter months... I want to be able to drive it for some time before I store mine away

So I think part of it is the ones in FL arrived with them knowing it would not be arriving with spoiler. My window sticker didn't even have spoiler on it and was not in the MSRP. I'm sure there's some legalities involved with NY/NJ port releasing theirs if it was marked 'pre-sold' or something.

I find this. Take a look blue A91 going to be tuning

If you look at post they didn't even dyno it since it was only 90 miles in.

This is correct. Reached out to Phantasm tuning to ask about the car and the ecu security issue. They confirmed it was not tuned at all as the ecu was locked.

All of this makes me curious as to how much aftermarket ECU's from AEM, ProEFI, Vipec, etc. will catch on with these cars. Flash tunes with modern cars have been fantastic in recent years but ECU security lockouts are obviously becoming a huge issue for the tuner world and owners interested in tuning.

seems my unlocked 2020 is looking pretty good about now. If I take it in for service can they update the ecu and lock me out?

yes so do service yourself

Might be on the bubble... My 2021 build date was 6/20

Fingers crossed

Someone said their 6/20 A91 had new ecu version. Pretty sure all A91 were made with it

Technically i do not think my 2021 is a A91. That is the "special" edition for 2021 with seat stitching and decals on C pillar. Mine is an A90 but with the newer engine specs and programing. It is pretty nasty stock. Handles amazing on the track- well above my skill level so far. Just need a little more hp to hang with a couple Modded Z06's on back stretch.

With enough demand the aftermarket will always find a way... ..eventually. It took HP Tuners about a year to crack the E99 pcm in the C7 ZR1. C8 is still a WIP.

I think the new ECU has an additional security chip on the logic board. So updates wouldn't affect you the same way. The new cars have different hardware it seems.

just a thought... is it possible to slap in older 2021 or 2020 ECU to newer 2021 (7/20 and later) to make it work? i'm sure there are some challenging issues with that as well but if those are minor, it might be a good interim solution..
