Transmission Flash to Increase Line Pressure

Hey guys has anyone ever done any logs to monitor line pressure in the transmission ?

I need to increase the line pressure for my clutches, SSP has recommended doing a transmission flash, but I want to make sure will increase properly so I avoid issues with the clutches slipping.

I need a transmission flash that will reach 18 bar of pressure. Anyone have any recommendations of any trans flashes out there.

Can anyone chime in about the GTS flash? I know for the F82 GTS, the trans flash DOES increase pressure, but I can't comment on the E92.

Most of the aftermarket trans flashes are based on the GTS tune, are you considering asking tuners putting out DCT flashes if they can do a custom file?

Clutch pressure is regulated by the tcu. The dme calculates load/torque constantly then it’s sent to the tcu to determine how much pressure to apply to the clutches to match the calculated Torque. If this is value isn’t accurate from the dme the trans will slip.

So This value needs to be adjusted through the DME side via tune and not by transmission flash ? Cause in my case with the supercharger im making way more power, and the clutches barely slip. I want to be able to increase the pressure cause the e9x trans dont run that much pressure from factory. I want to be able to fix this for good.

have you tried the GTS flash yet? I'm sure that might work well with your upgraded SSP clutches.

Not Looking for the GTS tune, looking for someone who can do increased line pressure for a super charged car.

XHP could probably do something for our DCTs. They don't show support for the E9x M3 but I'm sure they could do something about it to get the clutch pressure up for those who have supercharged cars.
They blogged about it too multiple times.

Yea seems odd that they support the non-ms but not M3s when it is likely the same trans with different programming. I think it might be because DME changes are needed also to make everything work and they probably dont have much experience with the MSS60 ECU, they seem like they started as N54/5 guys and move to S55s and focused more on turbo motors.
