Hi,

I am using a samsonas sequetial gearbox with MME pneumatic paddle shifter, I noticed that I can't downshift immediately when I step on the brakes, the system only allows downshifting once the RPMs drop. I use Ecumaster pro 8 ECU, but I am not using rev matching function, so can anyone tell me what is wrong?

Thank you.

Most paddle shift controllers have a maximum RPM where downshifting is permitted, since the RPMs will go up on the downshift to the lower gear and you don't want to exceed the engine's redline in that new gear. Proper technique for downshifting near redline -- brake, then downshift.

The M1 GPRP Firmware will reject a downshift request if the calculated Engine Speed after the Shift will exceed the Engine Speed Limit, the ECUMaster ECU may do the same protection (I haven't used paddle shift with one so I don't have hands on experience)

We usually reply within 12hrs (often sooner)
