XHP Reviews and Feedback!

I assume hes referring to the 8HP50, which in fairness is very similar to the 51 that the supra has.

It is very similar, but it is not the same, doesn't have the same TCU, and has variances in the valve body, and (not as importantly) different gear ratios.

I assume you're making a joke? 8HP51's only applications are the Supra, G20, G29, and Jag XE.

No one is scared or worried. Read through the thread a little bit and see what we're saying. OTS maps going to improve your 1/4, especially the safe ones.. To a lot of folks, "then what's the point." The more aggressive and custom tuned options for this specific trans in this specific application are still unproven. None of the fast guys have had enough time to really tune, really push, and really find out what the limits are and where the limits are.

The clutch pack seals are without question, a weak point. We have a calculated, but not proven understanding of how the OTS maps are going to perform on built trans', either. There's a ton of variables. Yes xHP is proven for a bunch of applications, but this -is- software, written by humans, or a relatively new trans (3rd Gen ZF85x).

To some, the worst case is pretty bad, and the best case isn't that great.

Not everyone is getting this to improve their 1/4 time by tenths of a second. Yes that is a factor that can be beneficial, but the overall drivability is so much better and that makes it worth it alone. With the ability to customize certain setting if you know what your doing. None of the fast guys have it yet, but they are working on something. Visconti is definitely working on something. Obviously, for anyone looking to make high power and best possible performance, a pure trans would be better route since our trans mechanically can't support high tq. But for $400 bucks, the software is worth it. Just like it has been for every other platform they had supported. It's not that deep bro lol

The tune would be worth it to me if it did nothing other than what you describe. The fast shifting in comfort mode drives me crazy. Not looking for crazy performance gains, but would love to smooth out the driving experience.

If you go on their app or site it shows you exactly what each stage does up to stage 3. Then in the custom settings thats where you can adjust things to what you want if you know what your doing. Thats where it can get dangerous if you dont know what your doing which I dont lol Which is why the OTS is more than fine with me because it is so much better.

I wonder if the Kies Motorsports WiFi ENET adapter will work? I imagine it should, it's what I use for MHD and Bimmercode now.

I have that one and it didn't work my orange MHD did though

Unfortunately, Kies Motorsports WiFi ENET adapter will not work as I have tested it already and the XHP app is required to have MHD (Orange) adapter or THOR adaptor.

Just talked with Kies directly today and they confirmed their WiFi Enet adapter will work with XHP.
*Disregard, it only works on F series cars* ?

Well.. we'll see. ¯\_(ツ)_/¯

Did you specify it was for the Supra? XHPs website has an interactive connection page and is only showing either the orange mhd dongle or pink Thor dongle are the only ones working right now

Yep, you're right, I stand corrected. Looks like it only works on F series cars. Sucks, I guess I'm going to have to add another adapter to the collection. That will be 3 adapters if I'm counting correctly, plus an OBD ENET cable LOL!

I, like some others, was very hesitant to jump on this. But after talking to Speed Industry (me and Malen go way way back, I worked for him for many years and still do side jobs here and there) I’m going to be testing it for/with them. I’ll most likely run the stage 2 map regularly but will test out the stage 3. And of course any customer maps from the tuners if they release any.

after speaking with some guys and getting a little back ground, I feel pretty confident that everything will be ok. i Do believe the trans will have quicker wear, but after conversations, I’m ok with what many think are realistic numbers. About as much wear when you tune e50 with the bolt ons. The fear of my trans needing to be sent off in a month after flashing is gone.

Tested on my 2021 Supra. Looks like the 2021s don’t have yet the custom settings since their firmware is different than the 2020s so using ots stage 3 for now. The shifts in sport mode are way faster and and crisper, did notice a bit difference (faster)in comfort. The only con is that the downshift from 3-2 in sport mode the car surges forward as if the rev match isn’t correctly matched to the speed of the car. Hopefully Xhp will fix that in the next update. My car has 602 so the accelerated wear was there already so ??‍. And yes it will work with the mhd Orange adapter.

I reached out to xHP for some answers to a few questions that I had. I have no issues with running these TCU maps with these answers personally. I will also give Visconti a chat at some point as well as I think a few tweaks are needed for my car at least. I also dont know what torque maps my tune is configured for so my tune may need a tweak as well.

• Line pressure bump is a custom feature that needs to be enabled by the user and is NOT enabled automatically.

Having said that, xHP calibrations can run a higher line pressure than stock if needed, to compensate for higher torque from tuned engines.

• If you do have slip in 6th gear, which is the weakest, the you need to enable Line pressure bump, seer the custom features description in our Wiki.
• Just for better understanding: The EGS transmission controller adjusts the line-pressure live, depending on the torque the DME sends to the EGS (transmission controller). This is why for optimal performance you do want an engine tune that does not use "bent torque values. See our FAQ and our blog article.
  "Linepressure bump" just raises the threshold on how high the transmission is allowed to raise the pressure. So if your clutches slip already, you need to activate the feature, otherwise you are burning your clutch pack.

If you are just cruising around town, requesting not more than stock power levels from your engine, you are not running any more pressure than stock.

• There are over 100000 cars that have gotten xHP flashed, most of them running stage 3. If there was such an issue, then all the forums would be full of it, but they are not.

Hi guys,

I’ve actually never posted here before so my words might not hold weight but I own a FBO A90 and a FBO F30. A lot of my experience is balanced between the track, canyons, and daily pushing BMW motors.

I have personal experience seeing xHP applied to an f30 with a b58 that was aggressively driven and used as a daily for years. What I can tell you is this:

• It is a mod that brought the car to life similar to what was experienced ecu tuning the b58.
• We had 0 transmission problems on the f30 and didn’t hear of any friends having much either.
• It endured a beating too - I’m talking high speed runs, canyon runs at high alt, driving it hard in reg city driving. The “reliable” upgraded hpfp gave problems before this did.

While this flash is seemingly new due to the recent release and variances in the zf trans that is offered in the BMW and Toyota applications, the guys at xHP have been reliably doing this for years. They could have rolled this out right away but took two years after the release of the car to do so.

I’m flashing my Supra this wknd and will let you know my immediate findings, but I’m pretty confident based on my experience and their track record so far.

Finally dialing in the XHP tune now that the settings are open. I didn't like some of the features of the stage 3 tune and I still think it's quite aggressive lurching me forward in my seat on 3->2. Might try and flash stage 2 with my current custom settings to see if I can chill on those last downshifts a bit.


I did make some great improvements on the fatory launch control. No more spinning through first and slapping redline for me.

Also apparently you cannot use the factory launch control function when start from 2nd gear is enabled. You have to launch from 1st.

I was having the same issue on the 3-2 downshift, here’s what did the trick for me after contacting Xhp, btw they replied back really fast so their support people is doing their job!

i went with -15%

What did you set it to? That is what causes those downshifts its the throttle blips

EDIT: I see it now sorry
