think the only gt pump that can do it is the phase 1 pump and that cant do much of a boost increase. Defo need an uprated pump matey. im using one of a ph1 golf gti and can easily get 3.5bar at idle.

would have thought the maf sensor would have to be tricked if youre using bigger injectors. May be why you cant get the pressure up.

something like a dump-valve sized hole bypassing the maf sensor. Im using standard injectors etc... so dont think i need to do this but scoff is your man.
this is what haz told me when i asked about tp sensor setting up for standard injectors and in your case bigger injectors
depends if your on std injectors or not. you'll notice there's a 'click' for idle position on the map, so it should click as it opens and again when it shuts. if using larger injectors you want to set closed position just past the click, as the ecu ignores afm during click and just runs off a set point on the map, thus overfuelling with larger injectors
New walbro pump fitted along with new copper lines and rubber pipes.
Seems to want to start much better now it has a propper pump.
Im having the alternator checked over as its not charging the battery.
Next week im hoping to get it motd
I'm so close to getting this car of to mot.
I can not get the car to idle well, i have read the Volvo Haynes and simply do not understand. I have set the tps so it clicks just on open and just before close, but the car still wants to idle at 600rpm which it will not, but does run slightly higher if i disconnect the icv.
Im guessing you get it to run slightly higher with the icv disconnected say 1200rpm and when its plugged in it should drop to say 1000rpm.
I have noticed there is a screw on the top of the tb on the left looking from the front that can be turned either way it let more air in and out, it does still want to stall if that is all the way in and no better if i unscrew it further out.
I noticed there is also a little bold on the top that has a cover on it that would keep the revs up if i brought it out but would that not open the throttle and mess up the position for the click on the tps
Can anyone help me out
i had to open the throttle using that screw that youre on about (the one that pushes open the butterfly) the other screw (if im right) regulates the flow of air through the little hole inside the tb. That is probably the right way to do it, but again im not sure so best speak to someone like haz, markey mark or scoff before doing anything
If i adjust that top grub screw the car will idle fine, im just worried that then throttle is not completely closed.
I could do this then just adjust the sensor underneath for the click.
thats what i have done for now but havnt moved the sensor as i didnt think about that. Seems to work fine but mine dosnt idle amazingly well anyway.
yeah but youve not got the idle control valve
truedose idle higher and all over the place when hot
