No Boost at all....need help

[andyg plym]

yes all stock aby. will try to move maf and see

[newsh]

Are you running the correct injectors for the chipset?

[javispa]

It may sound stupid, but is the throttle cable fine? A friend of mine was having boost problems and it was because the cable was loose / half broken.
By the way, I also think that moving the maf to the pressure size should need a remapping... at least I wouldn't do it without remapping the car, and without making sure that the maf is not going to blow because of the pressure.
I hope that you will solve the problem soon. Good luck!

To get the best from the set up you will want a re map but IMHO it wont cause the problems you describe.

[andyg plym]

yes i didnt want to put it there either as it runs too close to the manifold,there are threads on here where people have moved them and had no problems, but id rather move it, and also it has oil to deal with which all s2;s have

[A80Avant]

i have never done it myself,but i remember all the talks about moving the maf to the pressure side,that it always needed a remap to run properly.

[andyg plym]

i did run it before wiv maf on turbo and no filter to just see if it would cure it,but it was no better. that was before a new turbo tho. julian was runnin maf under the rs2 turbo that was on it before and said it ran fine. mind you it was runnin a digi-tec ecu.
Maybe i will put maf in front of the turbo just to see.

[A80Avant]

Andy, im pretty sure that if you move the maf to the turbo side without remapping you cannot run the car properly.I think you found your problem...

[andyg plym]

because with tubular zorst manifold there is no room for maf and an air filter. read somewhere it wouldnt need remappin.Currently on a homefry ecu

[A80Avant]

why? have you moved the maf to the turbo side without mapping for it?

[andyg plym]

took lambda out today and cleaned it best i could , i know you cant really tell just from lookin at it, it was sooted up badly . Car still not boostin rite, just sits below 0 most of time and maximum of 0.2 bar boost.
Could movin maf to under turbo be a problem?

[andyg plym]

yes we did didnt we.... wot do you reckon mate? Lambda now?

[merlin's S4]

If you remember we pulled up a lambda code last week, also map sensor at one point and mixture adaptation. And it stank of fuel when you shut it off, although this may just be a symptom caused by the main fault.

Bugga, Done it again!! I'm at my bro's house and his stupid computer keeps logging me in on his account.

darren ta, but did timin last weekend wiv bo and stu, could a fked lambda be a cause bo? Would vagcom not of picked it up?
