XHP Reviews and Feedback!

This is why I felt it was worth the money. I drive mostly in M mode, had never before noticed I was waiting for shift to happen after I pressed the paddles until I flashed stage 3 with sport plus mode. I concur the shifts are lighting fast now in M mode, it's certinaly the most noticable differences to me.

Yep! It's only going to get better as they release more and more updates to fine tune things. I'm very pleased!

I improved my best 60-130 time by 2 tenths of a second, which all in all is a pretty good difference. It is also fair to say that my best 60-130 prior to today was in near perfect conditions for where I live and was ran immediately after my car got up to safe operating temps. My 60-130's today were ran after an hour of driving in 71 degree temp with an insane humidity and tons of stop and go city traffic.

Thanks for the write up. What transmission mode were you in for the prior and current 60-130 runs? Sport with auto shifting or manual mode?

Always Sport Individual with Sport + Transmission coded and Manual shifting at 5800-6000 rpms. It's been noted that roughly 5800 rpms is when the factory turbo starts to flow hot air so that's roughly when you should be shifting.

Do you need bimmercode to unlock sport+?
Or does the xhp tune enables sport+ on the supra??

I have a Pure STG1 tranny that has always had a harsh/laggy upshift since install for 1>2 and 2>3. Hoping this can maybe help remedy or allow a tuner to adjust.

Very great remedy. I have pure stage 1 with p2uned G35 night and day. Way smoother

Do we reckon xHP are likely to adjust the map to reduce that harshness from 3->2 themselves? Makes me wonder how much we're all beta testing this for them ?

Also does anyone have experience with running xHP for a long time on the ZF8 gearbox, and what kind of interval you want to think about changing the transmission fluid at after flashing it? I think ZF make a kit recommended for doing it at 60k miles, but that's on a stock transmission

For the Sport+ setting, are you keeping Sport+ active for both Transmission and Engine? I have these coded as well. Thanks for the review. I just purchased this as well and I'm excited to try it out, I'm just waiting on my Orange MHD Adapter to arrive

Just saw this, but yep. Both are set to Sport +
I tried switching those to regular “Sport” and the difference is very noticeable in torque delivered abs how quickly it spools.

I wanted to think on this.... So I'll try and make this short. I've spent more money on less is the easiest I can say. I think its worth the money (full disclosure I didn't pay for anything, Speed Industry got me a license and map pack to test for the shop) BUT I don't think its like going from a untuned car to a tuned and dp car like some have stated. It dropped a couple tenths, it shifts much faster, honestly don't even know how because I thought it shifted fast asf before. The time you click a paddle or the shifter its shifted, they are now instant, again not even sure how since I always thought it was responsive before.

I went straight to stage 3 since thats what most will do, but plan on testing stage 2 and most likely running it. In comfort and auto the shift dont rush through and even smoother, like you have to really be paying attention to feel them now.


So it is an "upgrade" so to speak. I'm aware that it may decrease the life of the trans, but i feel so does tuning the car and running e50. This may negate some of that with the extra line pressure, who knows. But i do like the way it drives, not that i had a issue with how it did in the first place. I guess its like if you ever had a good set of coilovers and your car rode better, but you took it some where they adjusted the preload properly and the dampening properly and now it rides better, thats how i see this. Toyota/BMW did a fine job on the trans tuning, this just tweaks it to be a little more refined, a little more quicker, a little bit better.

I appreciate this take.
What I will say is that every car I’ve experienced xHP on had at least an e30 tune. With that, it seemed that you couldn’t reap the benefits until the trans was flashed as well. At that point, it was a completely game changer.

I’ll post videos of pulls against a GTR before/after trans tune to show the impact.

Thank you all for early adopting. $50 says one of you blows the seal for a clutch pack this week.

As far as I know, no one's blown a clutch pack seal yet, but 10000x will wait for a few updates before I pull the trigger.

edit: I write (well wrote, I'm just an architect [read: glorified manager] these days), but I know how bad humans are at writing software. I'll wait.

I think at stock power even stage 3 is safe. Enabling drag mode is clearly what will get you in trouble, or if you are using line bump. All of these are gonna affect your clutch packs negatively.

Unfortunately, I'm not a stock power. RIP, but I do have a Pure trans, so idk. I'm still waiting until other big guns have some data.

Not seen many of the upgraded trans boys yet using it, but the ones that have defiently reported different experiences than stock. Time will tell and the miles will show the proof. For me the shifting experince in M mode is just bliss

I'll be making the switch when I get my top mount installed. Hopefully by then enough data will be gathered. So far the big players in my area seem to love it.

I didn't get my Supra right when they came out, but how is the worry and skepticism about the xHP tune any different from an ECU tune? It seems like everyone started jumping on the ECU tunes the first day they were released. Why is everyone so worried about the TCU tune or am I missing something?

Most people who don't want stuff breaking worry about ECU tunes. That's why people harden a lot of aspects for the car to include axles, driveshaft, transmissions, etc.

Same with the TCU. People will be putting more stress on something not rated for the thing that it's doing. But hopefully built transmissions won't have any or minimal issues.

There have always been concerns. It's just some people don't care about those concerns and just fullsend without prepping the rest of the car.
