Finally got my APR FMIC fitted yesterday

Seems like a good tight fit, though i've now a power question I could do with some help with?

I understand because the induction loop is a little longer that there might be a little more turbo lag, but performance to me seems quite retarded now in second gear. I thought that the longer loop may just push this power further up the rev range but this doesn't seem to be true...

It's still quick, but it seems to have lost all sense of urgency in second and be down in third/fourth gear.

Does this sound normal? Especially before the car is re re-mapped to take account of the new IC:confused:

I wonder if it is it worth doing a pressure test or would VAG-COM flash up a pressure loss if there was a leak somewhere in the new piping?

The APR instructions say that performance can be affected if the O2 sensor in the intercooler is not plumbed in correctly....I doubled checked the extended wiring but that all seems correct, i'll do a third check tomorrow...

Can anyone shed some light on why performance is down?

one thing to remember about pipes is that for every 90 degree bend you lose 5% of your pressure! it might be worth relocating the actuator hose closer to the manifold

Maybe a leak somewhere? Have you noticed more noise?

No, the car doesn't seem any noisier than it should.

Just slower...

I wasn't expecting it to be quicker, but surely it shouldn't be slower other than a little more turbo lag?

it's possible that you could have more turbo lag, but a well designed intercooler should so this. did you fit it yourself?? did you leave a sensor unplugged or somthing?

Yeah I fitted it myself with the very good help of a mechanic friend.

I'm 100% sure that everything went on as it should.

Did you unconnect the battery?

Hi Adrian,

Yes the battery was disconnected for approx 30mins.

A friend suggested a possible problem but does it sound like a likely cause?

A dodgy solder for the MAP sensor?

The Map sensor cable had to be extended by about 30cm.

If the soldering of the cables was not spot on could this lead to dodgy signals being sent?

I would have thought that if this was the case then the engine light would flag up but, maybe this wouldn't happen?

it is a possiblity that dodgey soldered joints could cause funny signals, i've seen it many times in printed circuit boards where a soldered joint is acting as a resistor becuase of the incorrect type of flux, or even the wrong type of solder.... also if the wires aren't insulated properly it could cause problems..
