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 itís sent to the tcu to determine how much pressure to apply to the clutches to match the calculated Torque. If this is value isnít 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.
