Do s2 rsts have them and if so where is it and what colour?

Im still having trouble with my ignition timing retarding itself and someone said that it could be the knock sensor shorting or maybe broke?


"HELP ME"

Nick

 

THE KNOCK SENSOR IS THE GREEN SENSOR on the right hand side of the inlet plenum as you look at the engine from the front,,,

they are on most late series 2 turbo's,,,

not sure about early 1's,,,,,

 

U need to leave it plugged in.

Take the sensor out.

Wrap it in bubble wrap and cable tie it to somewhere away from the engine on one of the brake lines or somet.


Failing that dont forget, Std RST's retard with a bar of boost on a standard cooler mine as soon as u got into 3rd in the summer used to retard when standard.

as jake says

get it bubble wrapped and cable tied out the way

best mod i ever did to mine

 

Thanks for the replies chaps
What does the knock sensor do then?
Wrappin it in bubble wrap and cable tying it? why?
My car isnt standard its chipped and runnin a kent cvh 34,double valve springs, -31, arp bottom end bolts full stainless and filter!
The cam timing is spot on but there is no more adjust ment on the igniton timing???

Nick

 

remember and blank the hole tho on the plenum

 

nice one vrooom i was just about to say

 

U shouldn't need to???

I dont think I did on mine.. cant remember.
The knock sensor sense the engine knocking BUT due to shitty cams in rattly CVH engines it can interpert (sp) cam noise as knock and retard the igniton.

The bubble wrap because u need to insulate it from vibration.

If u run a bar of boost on a std cooler it WILL retard in the summer anyway.

Another knock sensor would be handy for that

Mr.h., Knock sensor detectrs 'knock' (det) and retards the ignition afaik.

wraping it in bubble wrap it wont corode. . and take it off so it cant retard your ignition?

If your car is chipped and running lots of boost on std cooler then shame on you

 

Just been out and bubble wrapped the knock sensor and made sure it was out the way and secure but its still retarded? Tryed adjusting the dizzy but no joy?

 

did youi block the hole it came out of?

Also check the vacum pipe to the ECU from the inlet. if its leaking it may be the prob.

 

There is no direct "hole" into the inlet manifold Vroooooooooooom


its just a tapped blank m8 no need to block at all as its already done and cant be unblocked without drilling out...



RE... ignition..


get your cam timing checked m8, could be miles out or maybe slipped a couple of teeth

 

Adam Ash, aaaaaaaaaah i took one off one, i should know that too

 

lol

 

Which means i can remove mine on my S2 engine in my S1

 

i've got an early inlet manifold for the xr2 turbo im taking off soon and swapping for the late one with knock sensor.... as my loom has a knock sensor


if you want it, its yours for buck shee m8

 

its a early rst one to clear that post up

 

Sounds good as i was wanting one!

do you need one with a knock sensor?

 

never had mine connected .... running 22psi ... good ol mark shead

 

The cam timing is spot on!!!!
Ive had this problem for over a month now its doing my fookin head in

Nick

 

S1 Ecu doesn't have a knock sensor input because they dont have knock sensors and thus there shouldn't be a plug for it in the loom.

I am confused!!!

mr.h

Check your air charge temp sensor(act) IN X OVER PIPE, as if this is faulty will retard the ignition, also drops boost pressure, also check the wiring to and from it , not touching each other, i remember this problem its going on a bit now, and most things have been checked, so check this out.


DAVE R.

 

Charge temp sensor, mine was faulty not so long back, only managed 10psi lol

 

I have a series 1. it has a series 1 ECU. it has a series 2 engine/inlet fitted. the knock sensor is not plugged as you said no plug on loom, so its useless i left it on thinking there would be a hole in the inlet if it was removed, but now i know there wont be i can remove it!


HTH

 

BOLLOX there is, i checked y.day 1-0 free postage onthe S1 inlet manifold for making me think im a divv
