I am on 120 cal, how does ecutek unlock? I thought you have to send the ecu for bench unlock and then use ecutek? I do have Ecutek and license, just need to figure out simpler way for unlocking without sending my ecu.

I have heard rumors that Ecutek will unlock 120 cal.
to clear up confusion. When dealing with Ecutek specifically, the first flash ou do with the software is also called an "unlock". Which is basically just flashing a stock file and allowing Ecutek to burn the flash license to the ECU so to speak.

That is totally different than a bench unlock which is changing ECU code to allow flashing through the OBD2 port. 120 ROM ID are "OBD2 flashing locked". the bench flash changes this. Without getting to deep into the ECU underpinnings, thats is the difference and why Ecutek cannot flash directly on the end user side. On the Tuner side it can.


I have received quotes from $300-$700 for Ecu bench unlock which is outrageous. Why canā€™t the unlock be part of the tune? Especially the ECUs that can be unlocked.
Is it just me or I feel some type of a way with the support group for Supra?
Wow, even if you are buying the software and tune from them itā€™s an extra 300-700 to unlock it?

I was under the impression it wasnā€™t a very time intensive process. Maybe Iā€™m wrong
Unlocks for Ecutek are more because a flash license is used during the unlock procedure. the flash license is several hundred dollars by itself from Ecutek. Of course this cost is passed onto the Owner. and rightfully so.

tons of people. Justin @ Twisted tuning is a forum member and he can answer those questions more specifically, but everyone who has used them has nothing but good things to say.
thank you


Thanks!! @Twisted Tuning can you confirm? Iā€™m trying to go with Jeff for the 93 tune. I do have a deskey with 375 points, and would also need a deskey swap.
see above. for the deskey, the license cant be transferred as far as i know. the person doing the unlock needs to have a loose/unmarried license for the bench unlock

Ok, thanks for responding Justin, appreciate it. I checked my ecu date and it is 10/19/19 with cal id 120. Iā€™m unsure if I need a bench unlock or just load a tune and see.

I saw that twisted tuning have unlock available on the website, will that not work with the situation Iā€™m in?

yes, 120 roms need a bench unlock.

Is it safe to assume at this point that 2021 models will not be tunable? Is it also safe to assume this will be the same issue for future year models as well?

Guys I did a ton of investigating to help narrow down tunable 2021 cars. Basically any Supra with a factory order date of 03/2020 when using Toyotaā€™s VIN look up database can be tuned. This is for VIN range WZ1xxxxxxxx034999 and lower.

You might still find a few VINā€™s in WZ1xxxxxxxx035000-035500 range that have a 03/2020 order date but theyā€™re less common. All Supras with an order date of 03/2020 will have ECUā€™s prior to the 06/01/2020 cutoff. As these cars were built 1-2 months after order date.

Any Supra with an order date of 04/2020 and a VIN of WZ1xxxxxxxx035000 and above you will need to pull the ECU to look at the build date sticker. These cars were built 1-2 months after order date which approaches the 06/01/2020 cutoff.

For example if you lookup VIN WZ1DB0C02MW034436 you will see an order date of 03/20. This car is tunable.

* Disclaimer * This is just a guide. To be 100% certain you will need to pull the ECU and look at build date sticker.

And that would be me. That VIN range (very low in it), Toyota says 03/2020 order date, and ecu label is 20-03-04

Nice, good news for you then. Let the mods and tuning begin. :)

Iā€™m literally about to buy a 21 Supra and I feel the same way. Like Iā€™d say a good 50-60% of the reason I am buying this car is for the tunability. Just sucks

What OBD link device did you use? I think maybe that's part of the secret. Also, are you on IOS or android?
