ok sorry and i know its kinda hard to explain....i just finished a bunch of parts on my Evo X and am not sure whats goin on....some times unless my ao48s are really hot the car will break traction going straight in 1st gear. IF it doesn't break traction and rips through the gear it shuts off my ASC (as if i hit the button on the dash). Any idea why?
car mods are
hks filter
hallman mbc
nisei intercooler piping
ets 4 inch intercooler
3 inch ultimate racing downpipe
3 inch test pipe
3 inch custom exhaust with burns stainless muffler and vibrant resonator
Z-chip fuel controller
and gauges/coilovers, wheels and tires and some aero stuff that obviously won't effect this situation

any info?

The ASC you can turn off with the button on the dash. The ACD I don't think can be turned off. There's only the Tarmac/Gravel/Snow switch.

If it is the ASC you're talking about, I'm not sure. Maybe the torque limiters in the ECU shut off the ASC when they're exceded, or something to that extent.

 

thats weird.

 

yeah i am talking the traction control ASC .....like i said its ok if the tires don't get all traction and spin some when i hit the gas. if it doesn't the cars ASC off light comes on the dash...weird. i am thinking the same thing with the torgue limiters but not sure if they are only on the MR and ralliart

 

i got the same thing a while ago when i floored it on a frwy onramp..from3rd to 4th... i also felt like my tires slid a bit since i did a sharp turn... i think theres a tread on this somewhere on here..

so much info on there...lol thanks!

 

Been happening to me too the last couple of days since i installed all my mods

 

I was having that issue after I installed my exhaust. It was due to overboost. I've turned the boost down and havn't had the asc off light come on since.

 

if the asc is on when launching the car hard the car is almost 90% going to bog off the line so when i lauch the car i shut it off

 

Yeah except thats not what he's talking about

 

I have had the same problem. I personally think it is an ECU issues. I have similiar mods and have had the same problem for awhile. Hard on throttle and the asc light just switces on. If you find out let me know

 

Is it actually shutting off guys? or is it just displaying the explanation mark while accelerating? if its just when accelerating its cause the tires slipped and you lost traction, it is the car telling you that you lost traction.

 

Try reading post #1 and then post #11.

 

Same problem here guys, new tune and new parts. Hard acceleration and the "asc off" comes on and the "!" with service needed or whatever is displayed. Not sure? Shut the ignition off and back on and you are all good?
