Cold Starting issue soon after twintake install...

[rich83]

But, if these engine ECUs adapt as you 'run in' new hardware, then it might not have shown up as an issue straight away.

Yes it would adapt, but would of learned it after a couple of ignition cycles Rich.

Not after nearly 2 weeks with no performance failings prior I find the hard to except...

When i had my REVO done Steve, the over fuelling fault only reared its head about 1-2 weeks later so anything is possible.

My GTI also suffers from thsi 'fuel cut' type intermittent sensation when occasionally in the high revs, and my car is (afaik) on standard map.

I have a twintake fitted but it suffered from this problem before the kit was fitted. VW have logged no faults and say they will not change plugs until 60k 

Which plugs are recommended for a standard GTI, as an improvement over factory fitment?

If you are not going to remap then fit NGK iridium BKR7EIX or if you are going to remap then you could keep the 7's or fit the BKR8EIX which are a grade colder. Both of these plugs are better than the OE NGK ones and you will find them cheaper to buy aswell

Check if the air mass sensor is in the right direction!

VRSCarl fitted it, so I hope so

It wouldn't make a blind bit of difference anyway. You can run round with your MAF unplugged and the car will run fine. The ECU will just run a default set of values.

But i installed it the right way and made sure it was pointing down into the turbo

Have you asked JKM their thoughts, Steve?

Hopefully you would have bought it or had it fitted by JKM to be than wanting their support with problems later on.....

The ECU uses what it sees coming out the back end to judge how much air is coming in at the front end.
