csimoes Posted October 22, 2013 Share Posted October 22, 2013 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 Quote Link to comment Share on other sites More sharing options...
TheRecklessEngineer Posted October 22, 2013 Share Posted October 22, 2013 Post up your PWM settings. Quote Link to comment Share on other sites More sharing options...
FridgeFreezer Posted October 22, 2013 Share Posted October 22, 2013 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.

csimoes Posted October 23, 2013 Author Share Posted October 23, 2013 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) Quote Link to comment Share on other sites More sharing options...
FridgeFreezer Posted October 23, 2013 Share Posted October 23, 2013 There is usually an arrow on the body of the valve showing direction of flow. For initial tuning you can ignore the PWM valve, I have no idle control at all on my V8 (laziness) and it's fine. Quote Link to comment Share on other sites More sharing options...
