Knock with ECUTek Map (after two years & no probs)
Hi,
My MY01 WRX was remapped by ScoobySport about 20 month ago. Everything has run just brilliantly until recently. I had noticed an occasional pop and bang and have since noticed the knock death rattle at high rpm under load.
The only thing of note is that she was serviced about 4K miles ago. The problems have only occured since then, but i can't say i noticed any problem immediately afterward.
Anything the garage could have to cause this ?
Anyone know if any of the current ECUTek remappers might have a look at this for me since i can't go back to Pete
Cheers .. Andy

Mark.
but what could they have done ? How could they have damage a MAF sensor... is there any way of telling it's damaged ? if it could be airflow.. what about a filter ? i think i might open up the air box and make sure my ITG's still in there and clean...

is it normal to hear slight knocking for a couple of seconds when the car is just ticking over when you first start it up? i hear a little knocking then it disappears then comes back for like 2 seconds then gone again. can happen a few times but when you set off everything is fine. normal?
