How worried should I be about increased knock activity....

MY00 classic turbo
TEK 3 remap
decat downpipe
STI panel filter

Basically, when accelerating hard through the gears I'm seeing the big red knock light flash when revs get to about 5K , especiallly in 1st and 2nd.
Dont normally get any knock for normal 'enhisiastic' driving.

Should I be worried ?

Note.. Car is also currently suffering from misfire / hesitation on light throttle which I'm also investigating..(see other thread) . Not sure if the misfire + knocj activity is related..

that shouldnt affect knocking, when was the last time you changed the plugs and leads?4 main rules
1:let it warm up before accelerating over 3k every time,
2: let it cool down properly after runs,
3:dont hit the limiter, i think if you stick by this then you wont have any engine troubles
4:use quality service parts, good oil leads and plugs etc, cut no corners

 

Hi,

Plugs were changed about 5 days ago (from PFR6b to 7B's) , and it was knocking before.

I have got a new set of leads to go in. Will post results

cheers

I never get anything other than a solid green when driving REALLY hard... mostly no activity at all.. V5 STi, 1.3 bar, stockish, Link ECU

 

When was the MAF sensor last changed?

 

MAF sensor changed about 10 days ago.... (this was done to try and cure a slight misfire / hesitation on light throttle).

I may put the original one back in because I don't recall seeing this much knock activity previously..

cheers

 

Put the original MAF sensor back in today... Knocklink activity has now disappeared. Hard acceleration shows no more than first green light.
