3 phase shunts and phase filtering are needed. The Focbox and Unity only feature 2 battery sided shunts. They are basically HW4.12 based and come with the downsides of that design.

@Evwan clearly coined the term shfi and trampa definitely owes him money for using a term he created. That’s how it works, right frank?
Also, does the new individual gate driver system used instead of the standard DRV have any benefits in terms of preventing drv faults? I am not very savvy on that stuff.

Is it safe to run screaming HFI?
I think you mean ScrH™FI®©

This seems to suggest from Trampa’s end that HFI can work but definitely not ASS, OP says otherwise but maybe that’s just because they tried to go all the way to ASS that does need phase filters and 3 shunts

When will the vesc6 mkVI be released? What will differentiate it from the current model? Does the current model have the requisite hardware to use this sHFI technology you speak of? Will the stormcore 60D+ work?
From Trampa’s website.
The VESC 6 will be re-designed & re-released in Septermber, Re-Marked as the VESC 6 MKVI & will be up for advance purchase as soon as we have a delivery date confirmed.
Looks like “Septermber”
Based on what’s in Vedder’s GitHub it looks like the IMU will change and it’ll be linked up via SPI (instead of I2C), a win for balance applications but not really a change for general esk8 use.

Please tell me you are familiar with “swerve drives” from FIRST robotics.
I think it would be incredible if Trampa sold a swerve module.

feel like Patrick has the market pretty cornered atm, and he has the advantage of actually being involved with an frc team, but would certainly be interesting to see if trampa could come up with anything innovative.

Considering a small 6S battery could be onboard the module along with the controller thus eliminating basically all the mechanical drive parts they don’t already stock. The idea in general is very feasible, for a robot printing the module frame could lower end user BOM from trampa to very low cost.
Then you need a central brain that also powers the modules rotation, sending drive signals. Bonus points if it has an automatic swerve module battery changing mechanism.
Yes, the MKV already supports sHFI.
New features:
The MKVI will have automatic sensor voltage switching via software, 2 x UART, SPI IMU, a bit higher current handling and Spin To Start can be disabled or enabled.
The sale of the MKVI will begin in the next days.
Production is already prepared and starting with the delivery of a missing component.
The VESC 6/75 will have the same features and is arriving around mid June. The only difference is the voltage rating and current handling and the fact that the 6/75 has no Spin To Start.

Are we talking less current or more? 
More!

Mk3’s ran up to 114A on dodgy shite freerchobby motors before overcurrent spikes occured, and 130A on flipshit motors (just didn’t test further). 120A is probably the “can run anything anytime” rating now

MK3-MKV use the same PCB layout in the relevant parts. But it seams like the recent DRVs are a bit more sensitive to certain layout features. This is visible when you swap out a DRV on an older MKIII, replacing it with a brand new one. The performance then drops a bit.
BV then did some testing and finally we found a way to place the components in a way that allows to push the VESC 6 harder, even with the new DRVs. Together with a better heat pad the total performance is now better then it was before. 120A with very good cooling is no issue when the motor is tuned in well.

So is sHFI just a silent version of HFI, or is it better at resolving too?
A lot better at resolving. You can even do highly accurate position control with it.

i’ve had em set 120a max for over a year (mk3/mk4) peaked at 260a while racing and i know jens ran his at 135a. was more curious is the new mk6 could do a noticeable amount more current

No, that is the limit of the Mosfets. But we will have better heat pads now as standard and the DRVs are now more stable, especially the new batches of DRVs.
The website is updated and sale will start tomorrow.
