I'm assuming they all are. There's probably at least a 1000 owners waiting to spend serious money to tune a '21 lol.
yep..... I’ll be 1/1000 owners looking the spend money on a custom tune as soon as it’s unlocked.

Just bought the car this week, and wow this sucks to hear. Will it still benefit from the MST Intake for the 3.0 if I can't tune it?
Are there any bolt-ons the car actually benefits from without the ability to tune?


Thank you

It depends when your car was made. Does it have an 03/20 or 06/20 manufacture date on the door jam decal?

Intakes don't add anything to begin with. As a matter of fact, more often than not, they actually lose power. Intakes help when other things are upgraded too, like the turbo, and the engine just needs more air. At that point the stock intake becomes a bottleneck. But on a stock engine, an intake is useless and just for sound and engine bay dress-up.

My suggestion is a jb4 and a quality catted downpipe (avoid CEL). It sounds amazing without being obnoxious and runs very strong.

Its not the door jam date. It’s the ecu date my man. The door jam date is irrelevant.

He probably just meant the same thing you did. If it's 3/20 then you're fine but if it's 6/20 then you have an extra step to check on. He just never followed up with a response after the individual replied.

i don't know if anyone is really working on it lol. What, do you have some programmer in the back just constantly crunching code to get this fixed? I don't think so. Time must be spent taking care of customers, installing parts, and tuning cars that can actually be done. If it's been this long, the reward may not be worth the work... at least for Supras (in terms of pure numbers). I do understand this Bosch issue isn't just affecting our cars, but still...

Yes, There are some companies to do ECU tuning for living e.g. PowerConcept.
Trust me, they worry about the new Bosch issue more than us.
