about 3 weeks ago i purchased a 04, evo rs. after the dealership i bought it from did not provide me with an owners manual . so i finnaly figured out what the switch/button in the center consol was for when i had my freind stand in front of the car and i pushed it. holy **** thius car comes stock with a intercooler sprayer!
i now know that u can hold down the manual button and spray it ,but when you put it in auto mode the green indicator on the dash lights up .
i guess my question is , when does it spray in auto mode ? is there a iat sensor that tells it to spray at a certain temp? cause i cant exactly launch, shift and hold down the button all the way down a quarter mile track ,not yet at least

 

Yes its an automatic sensor, but the sprayer really is good for nothing else besides making water spots.

 

It sprays when it wants to.

 

Replace it with NOS

 

hahaha 4sho

 

i believe it sprays depending on engine load tps and temp. maybe some other parameters. but again i really don't think it does much of any good. and u defiantly can not notice it.

I know first hand that at 140mph accelerating next to an S4, who happended to be accelerating at the same pace, the sprayer does make alot of difference. The pace at which we were accelerating at changed noticably when I turned on the sprayer. I know, not the smartest or safest, but all the same, it does make a difference.

 

hahaha
whatever you say Paul Walker

 

I wish I could get all the chicks he gets!

 

Haha, I was laughing at his statement too. Lol, felt like NOS, didn't it. Noticable difference, lol. Something to laugh about before going to sleep

 

The sprayer in auto mode is pretty much worthless. The way the ECU parameters are setup make it almost impossible to spray in auto mode.

 

useless, but i wish i had one just for the gadget factor

 

haha i agree with that statement

 

no you dont, acd is much better use of that space.

 

how hard is it to convert it to a nitrous sprayer ? is there a kit for it?
