Title: Dq250 Cxx Seat SuperCopa Launch Torque Post by: mods4cars on January 05, 2023, 05:44:16 AM Hi All
Ive adjusted calibration tables like KanLC_MOffset_kl , KanLC_dMMax_kl , MmrMAufbauLaunch_kl to try load the k1 clutch on launch control as the stock function just free revs to the KusLaunchNstall_kl setpoint . With these adjust there is no clutch pressure on launch , what else is needed Thanks in advance Title: Re: Dq250 Cxx Seat SuperCopa Launch Torque Post by: prj on January 05, 2023, 06:50:31 AM You are not supposed to slip the clutch/load it during launch control. You will overheat the clutch very quickly like this.
If you need boost, then the correct solution is to do that in the ECU. Title: Re: Dq250 Cxx Seat SuperCopa Launch Torque Post by: mods4cars on January 05, 2023, 09:23:57 AM Dmitri ,have you done any high level motorsport ? Ive 20 years + working on everything from Rallycross to LMP...
You are correct on cooking the clutch if your dumb enough to sit on it too long , but every high level racecar that Ive worked on that does stationary starts uses preload . Preloading the drivetrain = less shock loading + loading up the suspention = less load transfere = more grip off the line . On the Olsberg Fiesta , no preload on launch = 2 car lengths after 50 meters . Back to the SuperCopa's , for the past year I've been using a quick hack with KusNStallAbsuschMax_ko set at 2800 , KusLauchPBremseEinst_ko set 80 bar to disable the LC function + some other stall setpoints to allow preload on the starts . There has been very little additional wear on K1 clutchpack using 2-3 seconds for launch .

FWD crap is not "high level motorsport". Next time you need something give background information instead of waving your dick around. Title: Re: Dq250 Cxx Seat SuperCopa Launch Torque Post by: mods4cars on January 05, 2023, 04:18:14 PM Biggus Dickus
