My A91 Edition Supra has a build date of June 2020. Makes me wonder if my ECU barely missed the cutoff timeframe of July 2020 if this was the start of the revised/locked ECUs.
Personally, I have always wanted to simply own a Supra since I was a child. I love how this car drives and it captivates me every time I take it out for a spin. As far as buying simply for resale and investment, I don’t understand why. Purchase property, silver, stocks, gold, or whatever, those generally tend to better over time. But who is to say the a90 Supra will not be a classic one day?Theres probably a lot of people on here that bought a supra thinking it will turn out to be an "investment" opportunity as if current mass produced cars dont depreciate. those mark iv resale values were probably used to convince a lot of spouses to allow this car in their garages haha
I was saying that a stock car is worth more thats all. Wasn’t even referring to the 2020 vs 2021.But what does that have to do with this thread, the point was if you wanted to tune a car a 2020 is the way to go right now and I think many of the Supra owners want to modify the car. Nothing to do with resale value etc

We were asked not to talk about it, but it’ll end up going public soon anyways.
Upon earlier this week, we received our first A91 (that i know of in the world) to be tuned. Sending his ECU in to us to be unlocked, we came across some information thats never been seen before.
Bosch has changed the security systems on MG1 ECU’s. This means there is currently absolutely no way to tune the car. No bench flash. Nothing.
We’re currently working on getting one open to try and find a resolution around all of this. ALL A91’s are this way and possibly any other 2021 that left the docks around the same time frame as they did.
We’ll post more information about this when we know more and are given permission to do so.

Some people claim a specific build date. Before making any large purchase, id certainly check the Cal ID first. This can be done with any ecutek module. No need to send in the ECU to check.
Yes. If the dealer flashes the car with an update. Itll lock the ECU. Are they able to change the security system on it to where it can no be unlocked via bench flash like some current 20/21 models? Im unsure yet, but im sure John would know.Yeah, that's another good question, if you have a tune and take it in for service will they do a software update that kills your tune?
I havent confirmed if theyre able to change the security on them via just flash not. But if your early 2020 was locked and you've recently taken it in for an update, it will be locked, but can be unlocked via bench flash, just like late 2020/early 21 models.Is this only affected on ECUs for A91 Supras or is this also applicable to A90 Supras that have been flashed by dealers (IE, recalls, updates, etc.)?
