Auto Intercooler sprayer

[Grant-V7-STI]

I have a 01 v7 sti and its got two intercooler switches. the 1st one gives an approx 5 second burst then turns off but there is also a "auto sprayer" switch that i can push which must go when it needs it.

My question is, when does it actually turn on and off?

Is it certain boost level? (if so then how much?)

Certain amount of revs? (how many revs?)

Wondering about the same question with my V8 STi.

Hi,

I'm not an expert but have mine set to auto. Why would one when driving fast want to reach down, taking their eyes off the road and push a button when one should be concentrating on the road? I actually don't understand the "manual button" one bit.

However, if you listen carefully you can actually hear the "click" when the sprays turn on. I suspect it goes on as a function of revs and throttle position. Based only on experience it seems to come on when more than 1/2 throttle and around 4 revs.

There is bound to be someone on here, however, who knows the exact details.

The manual button allows you to pre-empt the conditions required to trigger the auto sprayer. The car for instance does not know the difference between sitting in the drive through of FatDonalds and being at the staritng line of an autocross or street sprint.

works on intake temp and revs and throttle application and injector duty cycle (not too sure on the last one)..

the settings can be changed from in the ecu to spray it sooner if u wish altho the factory setup is pretty spot on.

it sprays whenever needed when in auto.

use the manual one if u know u will be doing a few bursts of runs.. best to use the manual spray a few seconds b4 the run

if you know you are about to need a lot of power, you can cool your intercooler down

before hand with the manual button... clear?

Woah lol thats obvious but from what he said it sounded like it reprograms the auto function

lol yeah it was kinda obvious, thought you must have been a moron.

no re programming... don't be fooled by his clever expressions, like "preempt the conditions"... it just means you know the future, your car does not.

Yeah, I shouldn't use words like staritng, it just confuses people.
