possible traction/launch problem


L33

Recommended Posts

ive noticed since my build that if im stoped still and try to apply full throttle (auto) the revs just bounce up to 3k and back to 1k as if trac control was on but it is off

 

ive tried pullin away in every way possible, manu, od, L, D ect but all the same

 

just wondered if there is a safety feature still on the standard ecu to stop me pulling away? if i pull away half throttle then full throttle its ok apart from wheel spin and agressive pulling to one side which i guess is because i dont have a LSD? there were thoughts i have a torsen diff but considering i cant do a stationary burn out i have no way of telling.

 

the trac does work as if i leave it on it will light up green when its stopping the wheels if i apply full throttle while moving

 

just getting a bit embarresing getting smoked off lights while i sound as if im "kangarooing" where the revs bounce up and down and then when i do catch up i cant really let the turbo kick in as my a$$ wants to nudge them off the road lol

 

any suggestions?

 

i was reading up on the solaris and it comes with trac control function built in like the racelogic? so im thinking if ryan can fit it to my car it will get rid of this problem?

 

have noticed as well when on boost it sounds like its bouncing off the limiter? but only some times, possibly where the wheels are spinning when moving and the box isnt changing gear as the revs are shooting up to fast with no traction?
