i what to tune my car up a bit at a time so i was wondering. iv got a 31 actuator to put on my car, i put it on and it ran like shit (OVER BOOST),thats fair anough
but when you start messing with the mixture screw to match the the air thats going in what happens to the emisions? i meen mostly when idling coz it will be rich as fcuk then and the plugs will get all shitted up. or am i wrong? what's your view as im trying to get my head around it
( im not going to mess with the mixture screw) before you start
thanks for looking

 

mixture screw just adjusts the co2 table in a linear fashion

( ive only got a basic understanding, so ill let the experts go from there)

on a rs it literally just moves the co content up or down the scale.


to change the mixture you need to have the car mapped so that it only richens on boost

 

RIGHT so to fit my 31 i would have to have it remaped and not adjusted on the co/mixture screw?

 

if you adjust the co screw, i expect youll be posting next week that youve blown it up,

also, you cant just fit a -31 actuator, you need to set the boost to a safe level,

ie, you cant get a standard cossy, or rs turbo and run 25 psi,

it will blow up.
theres always a picture of a big bomb explosion on posts like these, i expect some one will post it soon lol

 

thanks for your help in not going to touch anything. i was told on here that i could just fit it now but after trying it i found out that it wasn't that easy i know you got to get cams chip and all that stuff. i just thoght that when you put preformance parts on your car you had to adjust the co/mixture screw but you told me that it had to be remapped so thanks for ansewer my question
