Thank you. We need more videos actually displaying the troubleshooting. Im still struggling. New dongle should be in soon. Hopefully it's the 🔑 to solving this issue.

What’s going on?

[@user-ug4yt3sd6h]

Question fellas, why the 28i sdrive 2015 with 8 speed trans .. not comparable with xHP??

[@dearbornjeremy]

Great video. Thank you for sharing your knowledge!! I may add MHD to my 35is. It’s not a track car so would you still recommend XHP as well?

[@erez161]

I appreciate the positive feedback! Also yes, I would definitely do both MHD and XHP, it turns the car into an entire different beast. You will never get bored of driving your car haha. Just make sure your maintenance is up to date and you have done the DTC transmission oil change. I will be doing a video on that here soon.

Hi , have you ever try your Z4 on 1/4 mile ? with mhd stage 2 + ? and Xhp ? what are the difference ?

[@erez161]

Not yet but planning to. You definitely need the transmission tune though. I wouldn’t skip out on it, it makes a huge difference.

[@brigham1111]

Really appreciate your video. I have a 2012 Z4 35is with MHD and a few mods. XHP is my next step. You mentioned transmission life being shortened. Is that with regular driving? Or just due to running at higher line pressure?

[@erez161]

Thanks for the feedback! The transmission life would only be shortened depending how often you are launching the car, you will be fine with regular driving and anti-lag

[@Eazykilldavis]

Higher line pressure we're not shorten the life of the transmission. the only thing it does is prevents it from slipping during shifts which will lengthen the life of the transmission under the greater power load.

[@Eazykilldavis]

Things that effect reliability of a automatic transmission. HEAT/OVERHEATING, fluid level, and slipping.

[@N54hvmm]

You can leave the adapter plugged in? I thought it would drain the battery? Or did you plug it in before you started recording to get ready

[@erez161]

Yes the newest one shuts off when you lock the car

[@treyvergano9812]

How do you cycle the ignition

[@erez161]

When you first get in the car, put the key in, press the start button twice, wait a couple seconds then press the start button again.
The car will then be completely off, then start the process again.

[@Eli-iq3ux]

Would the MHD tuning work on a BMW Z4 2005 2.5 L??

[@erez161]

No sir, this is only for BMW’s with the N54 or N55 engine

[@hpsvirk]

Will the MHD tune work on 2016 z4?

[@erez161]

Yes as long as it has the N54 engine.

[@thingsforfree27]

Xhp tune is good and make a difference when your tuned on e85

[@erez161]

Ill be doing E85 once I buy the Nexsys Port Injection kit.
