The M3 software has a lower max clutch pressure (15.5bar). M3 GTS only raises it to 15.8bar. The regular 335is / Z4is TCU software allows much higher at 17.5bar. If you are trying to make any real power I would stick with the regular TCU software.
Would the syvecs be able to control the dct though and then go to the hardware limit which if iirc is like 25 or 28 bar something crazy like that
Well I did with my Z4 oem software and car started slip clutch after 580w,after M3 GWS and GTS software it’s holding till now 720w and we now going to try put more so I dun understand
Your DME tune was not optimal then and probably commanding less than the 15.5bar of the M3 software. M3 software expects less reported torque so you may be hitting the last breakpoint there in the TCU with your lower reported torque.
With a proper tune, the Z4/335is software will hold the most power.
Really dunno how is this,we tryed everything on syvecs with oem software and my DME guy really know works with syvecs did a lot 1000w+ cars,can you help us how to make it ?
Also kris from SSP told me Z4 can’t make more than 15bar and now some saying it’s can make 17.5,in my experience the oem Z4 software holds less clutch pressure than GWS GTS,tryed everything on syvecs to make that clutch holds but it only happened when I get GTS software
Oem soft just holds till ~600w and gts holding till now ~720w.
Well, I'm up and running on Syvecs. So far it's made 623hp on 93 pump. Going to pick it up hopefully this Saturday and put a few hundred miles on it, and then switch to straight E85 and shoot for big numbers.
Ill report back on how the bluetooth module works out.

What about the m4 tcu, could that be transplanted into our cars and does it offer better clamping force.
