need a knock sensor for testing purposes,anyone got one lying about,will pay,tried the wanted section but it will be winter time by the time i get a reply

 

yeah ive got a few lying about m8,im sure i can spare 1 for you.

 

nice one,where in central scotland are you?
what you want for it

 

give me what u think its worth to you m8,my garage is in cardenden,fife,about 20 mins after you cross forth bridge.your welcome to come get 1.

 

shit,bit of a trek,especially for a shonky rs turbo to do
hold the fort for now as i mite have sourced one closer to home
cheers for the offer,i mite just need to take you up on it at some point

 

Why not just remove yours from your inlet, blank the hole, plug the sensor in and fuck it off behind the heater box?

 

SafeChav, Unless im blind and can see metal where their is no metal, you dont need to blank it off

 

Yours will be different to a s2 one mate s1's aint got a knock sensor.

 

antony215, Ive got an S2 engine fitted and a spare S2 head/inlet...I gave someone my spare knock sensor and upon taking it out I realised their wasnt a hole where it was...think about it, why would it need a hole in the inlet to measure knock

 

Just checked you are right there is no hole i always thought there was a hole there

 

So did I till I had a look

 

because you have an early 86 S2 inlet which didn't have the knock sensor

 

Really? I do?...

read the rest of the posts



clue - No I dont

 

What you goin on about?

 

He means there is no hole to block off even if you have a knock sensor

 

Knock sensors and in reply to:

....what about you?


I have 2 S2 inlets, and they do not have a hole in them when you remove the sensor!

 

OHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHH

I have to confess i've never removed one, but i get the idea now

 

lol,ive never noticed either,would have noticed when i removed mine but
anyway got 2 knock sensors so its back to ava on saturday for some more testing

out of interest what does removing the knock actually do?obviously it cant detect knock from the engine as its not connected but will it not get other noises from around the engine bay
also what would a fucked knock sensor do to the power as in how much power does it sap,as im not gettin any knock,but the ignition is being retarded so presume its faulty KS,or fuckin hope it is
what other things can cause the ignition to be retarded

 

Well by plugging a sensor in and just tucking it away, it means it won't detect knock. The CVH top ends are common to fool the ECU, which results in ignition retard when theres not actually any knock.

You're probably thinking why can't i just unplug it, but if you do that its permentantly retarded

 

surely this i only a short term solution as i would like to sense knock if it is there,didnt know that unplugging it just retards ignition,would explain my mates runnin like shit then

 

Well if the cars set up and running right you shouldn't get any knock.

EGT and AFR gauges are VERY handy if you're worried about it though.

 

there isnt any knock,but it seems that the ignition is being retarded at 4.5k or thereabouts,thats why ive been told to source another sensor and booked back in this weekend
if its not the sensor what other possibilties could it be?
ecu?

 

If you know for sure its not knocking just plug in your spare sensor and cable tie it up out of harms way

 

Could it be that with solid tappets its detecting knock from them? iirc you do have solid tappets jamie?

 

Could well be!

 

how fuckin scary,i had the same thought today and was going to pose the question to alan when im in ava next
i think we might just try it with the new sensor fitted then ill get it checked with the knock sensor removed and moved out of harms way,just to see the effect it mite be havin by havin it fitted

 

At the end of the day solid lifters are always going to clatter being as they have clearance from the cam lobes, a standard cam is perfectly silent because it uses hydraulic lifters.

I wouldnt be at all surprised.

You wana do a run with it connected and then do a run with a spare sensor connected in, i bet it makes a difference!
