Can’t wait for the next video

Por fin! Thanks for this. Looking forward to the next chapter.

EXCELLENT description. Do the B48 engines in the 430i have the mhev system?

[@NoBrainerTalk]

I believe currently it does not, and this is upcoming for the models with the B48TU2 engine.

[@SM-gd1ie]

Nice explanation thanks

[@alibabaei1953]

I want to implement this system in my 2jz cressida. its so good😂😅

[@jayp340]

Are there any disadvantages to tuning the tu1 equipped with the 48v system?

[@NoBrainerTalk]

That's a good question and the honest answer is I don't know. Any added complexity over the standard internal combustion engine can be a factor.

[@gendaminoru3195]

What about PRE-TU mild hybrids? I don't see purple cables or 48v batts on those, yet they have the regen indication on the dashboard which you can also feel engaged as you coast or brake. Is there a video pre-TU?

[@NoBrainerTalk]

Hi, there's no 48V mild hybrid system on pre-TU B58s. The regen indication of "Efficient Dynamics" on the instrument cluster is for the 12V battery and refers to BMW's now quite old system "Brake Energy Regeneration" (which charges the 12V battery with the alternator during braking, coasting or decelerating).

@@NoBrainerTalk So there's no power assist on launch then.....?

[@NoBrainerTalk]

@@rodmanser7573 correct.

[@VTECBrey]

Very valuable video as always! Do you have any information based on BMW TIS documentation about valve deactivation system?

[@NoBrainerTalk]

Hi there, do you mean in respect to cylinder deactivation system? If so, I do not.

[@VTECBrey]

@@NoBrainerTalk Yes, last time I doscovered a very interesting actuator on the cylinder head near exhaust cam consisting of two pushrods that act on rocker arm pin via som sort of pushbar.

[@rayman1375]

Hey. can be externally charged every day? or this can damage the battery life?

[@NoBrainerTalk]

Hi, do you mean trickle charging the 12V battery? If so, this is possible.

[@neilsg2001]

11hp, surely all this is for tax breaks?

[@NoBrainerTalk]

Not impressed ha? :)

[@jbmectronic4314]

Yep, its to save the world //politicians with subsidies

[@torentmonkey]

Ah shet, they took away my water meth compartment with the 48v battery :(

Getting nerdy.
