hi all
first ill start by apologising for the long post lol

i took my s2 in for a set up at a local firm and it appears that it wasnt raising fuel pressure with the boost so further investigation revealed a dodgy connection to the fuel pressure actuator.
when that was fixed it was then massivley overfueling so he removed the fuel pressure actuator and it had been wound all the way in, so my tuner recons that they cant be wound back out once theve been wound in, so he said i have to replace this then go back which has left my car very poorly as it keeps cutting out after about 1 and half miles and i have to switch it off then crank it over and eventually it will start and drive ok again.

so my question is ,,,is it true that the fuel pressure actuator isnt adjustable

i have tryed another actuator on it but it ran even worse coughing and spluttering
just wondering if its worth putting another metering unit on from a standard car

any info would very much appreciated
thanks

Thats rubbish mate, you can adjust them in either direction, all he had to do was turn it anticlockwise until the on boost AFR was correct... Job done!

 

any chance of a pic just so we are deffo talking same object as i think you are on about regulator not actuator

 

it bolts onto the side of the fuel distributor on the metering unit

karlos thats what i thought coz it would be a bit daft if it could only go one way

im a bit unsure what to do now as i cant even drive the thing i might get another metering unit

 

plus 1 mick
did he even attempt to back the fuel pressure off abit??????

 

he said he did mate but im unsure if he did

 

Anyone know what voltage the regulator should get. I'm only getting 8 volts to it but thought it would be 12? I'm not getting any fuel to the cylinders from the distributor wasn't sure if this could cause that?
