removal of airbox resonator?
i now read that even the removal of the standard airbox resonator
can cause maf failures.
woa!
is that true?
anyone with previous experience on the subject?
the guy that designed/built the maf sleeps at nite?
it would be nice if we had his email dont u think?

Justin - from what I've read these holes are often plugged to make sure that you are still getting cool air from the wing rather than engine bay air.
Check over on i-club and see what the latest trends are but I think masking them off with some sort of duct tape might be the thing to do.

I think John Banks mapped a car with the resonator removed and found it to be running lean, (after a check with Delta Dash), untill he re mapped it offcourse, with a Tek 3.

Wrexy,
The "lean" car getting a TEK3 was mine. Turned out to be a faulty lamda sensor. The car was running filthy rich after all, like they all do.
I did have the MAF sensor out at one stage during the fault finding, found it to be fine and clean.
I have been running without the resonator for two years now with a K&N panel filter and had no problems.

WREXY it was one of those "do we believe the lambda sensor or not" at first it was reading just a bit lean and everything else seemed OK so I added a bit of fuel and blamed the resonator. Then the next time we logged the car it was incredibly lean it was taking the pi$$ (suggesting about 1% CO - basically unbelievable). A few (!) lambda sensors later and we got there.
thanks guys
i ll stick with the stock airbox without the resonator crap but i ll fit that 90mm cold air pipe from australia(looks as an excellent idea)
plus i m gonna use a lot of thermotec for heat insulation.
when the apexi arrives i ll compare the two directly and see how we go...
after eliminating the posibility of afm failure from oil, if it fails on me its either the vibration or the afm itself!
be brave!

Nope full de-cat, but I think the MAF and resonator are there for a good reason, and a bit touchy about messing with them, especially for what you get from it.
With all the reported MAF failures going unnoticed, causing engine failure, I would leave it. But thats me.
