new XHP stage 3 update

[Caden Yeatman]

What update? I don't see anything on the xhpflashtool Instagram

Edit: adding photo so people don't have to search.

Can’t find it for the m340, should be the same right?

I don't own an m340, so I can't answer this for you.

Here is video footage from on track this weekend of how fast the shifts are now with this update. YMMV depending on DME tune and power level.

Fact I know this tracking from iRacing makes me giggle. The front end scrub towards the end on T1 feels so real

After having the new update on for a couple days I can also confirm the 1.4 map is definitely spicier in sport, even when you aren't at WOT. In both auto and manual mode the upshifts are more aggressive. I noticed a difference in normal/comfort shifts as well, also seems to let the rpms go a bit higher than before when driving normally before upshifting.

I reached out to xHP and they said that it won’t be out for the M240/340/440 until the end of next month at the earliest. It’s currently only available for the Supra and Z4.

Yup, turn 1 will expose any and all mechanical and aero grip inefficiencies for sure. It’s basically been my control for my suspension setup changes for 3+ years now.

My latest change is adding 13mm spacers to the front to widen just the front track. It made a noticeable difference.

Anyone know if a MHD O1 stage 1 flash would overwrite xHP?

No. They are two separate control modules. MHD is DME, XHP is TCU.

You can even run XHP on a locked DME car.

Thanks

The cas has been flashed to stage 3 before but now that I log in via xHP it shows this. Is it because it’s a new login?

No. The app needs a chance to upload the data from the session every time you flash the car. If you closed the app immediately after it was done flashing, or if your device was on airplane mode and then you closed the app, the session will not be stored in your flash history.

Amazing thanks you. This is not the device that did the flash. I was expecting it to “download” the flash history from the control unit.

to triple check. It’s only a xHP flash that allows the gear indicator to show next to drive when in non-sport mode right?

so if I am seeing it in normal driving mode then it’s definitely flashed.

Correct. If the transmission is in D and you see the gear number, it is definitely flashed with xHP.

Thank you so much for the quick reply. Put my mind at ease. Now to download the upgrade pack and flash it to the new version and delete stop start .
Having never flashed the transmission before I read lots of different settings.
Is there an OTS version like with MHD?

I installed the update about 2 weeks ago and decided to try stage 3 and actually like that better over stage 2 for daily in non sport mode. Sport mode when you get on it definitely shifts at higher rpm’s (like at 7k) and downshifts faster during braking. I don’t feel like it shifts too hard though - just quick and positive.
