I have finally sortet out how to lounch hard on the racelogic launch contol on our damn slippy non prepped airport tracks...

 

The car now launches really fast....well, as fast as it is possble on a not prepped track.

 

The racelogic does it´s magin in the first 2 gears, also.

 

Problem is, on both run´s I launched like that, I onlce wan´t able to get into 3rd gear and the other run, I couldn´t get into 2nd.

 

I tried to do a granny launch then and shiftet at 7000rpms (instad of 8000+) and had no problems with the gears......

 

I have TRD engine and tranny mounts.

RPM limit is 8200.

I may have hit it on the missed shifts, but don´t know if that´s the case.

 

I never had such problems bevore´...not in my Vette, not in the Viper...and not in the Supra either....and the tranny shifts perfect all the time.

 

Just on aggressive drag racing, revving as far to the revlimiter as possible and even maybe hitting it sometimes (lack of practise), ...and shifting as fast as possible.....I have the problem with 2nd or 3rd gear........

 

Any idea what may cause this problem is highly appreciated.......

No idea why it happens but the box I currently have in is doing the same and getting on my tits, except its happening in every gear when driving hard. Drive normally and it changes fine but whats the point in having it to drive it normally :devil: Hopefully when its swapped for one im currently having rebuilt the problem will be solved.
