[stormgreysupra]

Let's use this thread to share our experiences and feedback on the newly released XHP software for the Supra. Before / After 60-130 and 1/4 mile and other testing would be very welcome!

So many people are going to burn up their trans' not knowing what they're doing.

It's available for purchase, I just placed my order.

As someone who has no idea what I'm doing, what do you think the safe options will be? I definitely plan to research and learn before flashing anything.

XHP is officially ready for purchase! I updated this thread so we can use this as a general XHP review and feedback channel!

Appears to be prepurchase only at the moment and releasing on 3rd may according to their indtagram account

I’m hoping for some sort of tune/settings option from major tuners to complement their OTS and custom tunes. Not sure if tuners do this with XHP for other platforms.

XHP support is officially available for the general public! Who flashed it already?

I was just about to ask this same question. You beat me to it ?

My concern at this point is being tuned conservatively to safeguard my transmission. If I flash this, and it changes the torque limits is that then going to basically destroy my transmission. I want stock torque limits but I want faster shifts.

There’s an argument going around that since raised torque limits will prevent slippage there’s actually less wear on the transmission.

There’s many people with Gen 1 B58s and ZF8s who have been running a Stage 3 XHP flash with Stage 2 ECU tunes for years and haven’t had any problems.

Increased pressure/ clamping force may lead to less slippage. (Sounds like a band aid to me). The increased torque limit by itself doesn't sound like it would improve anything.

I'm on a Pure 850 and flex fuel and stock transmission at the moment. So if this transmission tune removes/ overrides the limit set by the ecu tune, it could be a bad day.

Anyone successfully get settings changed for you tune? Mine keeps giving this error and everything is grayed out.

I have been running it since yesterday, it makes daily driving so much smoother and manual shifting is much faster now too
