HELP!!!!! PWM issue


csimoes

Recommended Posts

hi

MSnE installed, everything is ok.

all connections ok, all tested.

car runs

but if i connect the PWM all hell comes loose.

it starts to get instable and goes up and down in the rpm.

if i disconnect the PWM i get a stable 900rpm'ish

the car is allready at temperature and with it connect it starts to go up and down.

when cold is the same thing.

HELP!!!1 :)

The idle stabilisation is a closed-loop system, when the settings are out it will cycle like that, it's nothing to panic about it just means you need to tweak it.

Until all your other settings are good you should not get caught up trying to tweak the idle control or you will move the goal posts.

ok.

disconnected the PWM and i'm running without it. (it's there but disconnected)

this morning it started at 550-600 then after half a minute or so it went to 900 something.

for initial tuning i can leave it off and worry about the rest right?

does it have a right way of installing it or it doesn´t matter?

what i mean is, it doesn't matter if i connect the back of the plenum to one side or the other of the PWM?

another thing, does it closes completely and doesn't let air pass? because i blow through it connected and the air passed, blow through it disconnected and the air went by it again?!?

(the car was off, just witn ignintion on)
