I bought this tool few years ago - never had an issue with changing out spark plugs https://www.fcpeuro.com/products/14mm-spark-plug-socket-w-long-extension-cta-7654

Yup, I have experience lag and the OTS tune (93 Stage 2) doesn't run as smooth as it did before. My car exhaust volume also increased a notch or two. I've done multiple pulls and runs with my friends behind me and they also noticed it too. Let us know if you experience the same issues after your...

Great that it worked out for you. The accelerator pedal sensitivity has remain the same for me.

I've tried that - doesn't work on USA spec Supra's

Yup, I got the tool years ago because of you. It is still useful to this day

The super license create mirror image backups and restore points of your DME

@WaveZero MHD got back to me and I was able to flash MHD+ back into my car. If your car is on software ROM version 5D 55 32 DC 05 (5D 55 050 220 005), in the MHD flash options, go down to the bottom in the "force software field" paste or enter this value 0000630532DC and reflash. If the intial...

Only 2020's and early 2021's have the luxury of doing it if you have the mission tuning unlocker tool with super license (Unlimited backup and restore). That is, if you backed up before the remote start coding.

Do you know which ISTA version your car is on?

This is the other thread that talks about this issue https://www.supramkv.com/threads/suspension-clunking-noise.12641/page-4#post-381017

For remote start to work, he coded our US Supra to a Z4 (Euro). MHD just got back to me so I'm going to do more tests and flash the DME with remote start again later today when I'm off work.

You should do more tests on a completely stock Supra that doesn’t have anything disabled and push out an update to fix the exhaust flap issue. Edit: Telling us to buy an aftermarket valve controller when our factory valve worked fine before you coded remote start in our cars is inexcusable and...

I decided to restore one of my backup DME to my 2020 without the remote start coding. After driving with it a few days with just a 93 map from MHD and no MHD+ features and the exhaust flap staying open 24/7, it wasn't worth the effort to keep it. My butt dyno felt the car wasn't running...

its memory and/or completely off. If you're on the latest software you can't code it out, you have to press the button to turn it off every time you start the car or code the car to start in sport mode instead

Yes, you can start it from the Supra app; you press the ventilation icon on the app.

You will have to press the button to turn off auto start/stop every single time you start the car - it is the same case for me. I disconnected my battery many times in the past, and my exhaust flap functioned normally before this coding - no ecu relearning needed. I've been driving the car...

To add on to what everyone said above me, once you enter the car, you to put your foot on the brake and/or clutch and press the start button so the car stays on. If you try to drive off without doing this, the car shuts off.

it's around a minute when I use the feature from the toyota app

I've had no issues with my OEM valve, spring, connector, etc. and I drive it all year round including winter time in NY. 80k miles on the car, w/ 65k miles on the aftermarket exhaust.
