Bad idling

[breitling]

Breitling,it seems that my MAF although indeed has a problem,the problem in my car was the 2 bolts on the inlet manifold where all the earth cables connect from the ECU.Since i tightened them the idle went back to normal,i have very good fuel consumption again,no black smoke.and only a 561 fault code which i suspect is from my fuel filter cause my fuel pump is also a bit louder than it should be.Check if the bolts are loose and also check the MAF again.

Hmm.. i have checked the earth but will do it again.
I will also try another ecu.

Today i have tried with another RS2 ECU box. Original box with original chips.
The idle is stabile and steady. Hmmmm

hmmm...that is odd....what could the ecu remap has to do with this idling problem?
Also breitling,could you send me a couple of pics of your MAF setup with the airfilter(vasilis3690@gmail.com)

[breitling]

Yes its odd...

Im sorry but i dont have any pics of the maf.. its just a bigger pipe. looks like the original.

[A80Avant]

i mean,did you use the RS2 air filter too?
or did you go with KN filter cone?

[breitling]

I have a cone filter.
Still i have the same problem. Tryed with another ecu. Another chip.. still the same.

But when i connect the original ecu it runs flat on 3000 rpm and up..

Can it be because of the 3,5" maf house and the bigger injectors ? I have the orange 550cc.

Soon im going mad!!

oh the maf house is bigger than original now?
and when you check the original ECU you do it with the original maf,or the modified one?

As you know,my idle cured as soon as i tightened the ECU earth screws on the inlet manifold.Other than that,although the maf is original in my case,and needs to be changed as well,it still holds up well.

My problem is allmost cured. The camshafts were not correctly installed, markings did not meet. Now the markings are right and the idle is very good, but now I can't get any boost pressure, oly 0.5bar. I think I know were the problem is, my camshaft marking is on the right side and it should be on the left. I will try to put on the left side and let you know.

Yes its bigger than original and i checked it with the modified one.

My camshafts are also in right position. My tuner told me to make a cross inside the maf housing. If thats not working im gonna try with a new maf unit. Or maybe i need to buy a new tps.
