Where can i get one of these from??? When i put my 106 downpipe on i will need to sleeve one of the lamba sensors right???
Lamba sleeve?
-
#1
-
#2gmc do them
-
#3hang on, what exactly are you doing ?
-
#4hes putting a 106 non cat mani on his vtr i think
and wants o sleeve the lower lamda -
#5ah right, you sleve one sensor and leave the other at the bottom.
-
#6ive got a 106 downpipe to fit to my mani so it will decat my manifold, so i need to do something with one of the sensors dont i ??
and the other sensor screws into the manifold? -
#7Yep you just leave the top sensor where it is and put the one after the cat in a sleeve
-
#8i see, thanks.
is this the same procedure for the raceland manifold as i think im going to purchase one of these instead of arsing about with the standard mani -
#9they sell the sleaves on kam racing
-
#10yeah i think so wat ever mani you get youve gotta sleave that second lamda or the engine mangement light stays on i belive
-
#11thats correct mate. you need to sleeve the 2nd lambda. once the cat is out the mixture will be rich. you need the 2nd lambda sensor to be read clean, so the idea is to fit it to a sleeve and this tricks the ecu into thinking the cat is still in place.
gmc do them and a few other places as well.
then its just a case of fitting the lambda to it and securing it out of the way
with out it, the ecu light will come on and bug the shit out of you -
#12does it also put the ecu into some crazy mode?
Ill get a sleeve if i can find one on one of the sites, ill check cam and gmc now.. -
#13
-
#14Yeh, i think so.
-
#15it may send the ecu into a safe mode when the light comes on?? im not 100%
mine used to come on and off all the time even when i had the sleeve fitted.
you will also need a plug to blank off the hole in the manifold or decat pipe where the lambda should be. -
#16that is the correct sleeve from gmc matey
-
#17ok and is that lamba blanking plug on kamracing the right plug?
-
#18yeah it is i belive m8 but just ask them on here
-
#19fuck that 15 quid for a sleve home made with a coper pipe ftw actualy come to think of it i dont have mine in a sleve and the em light hasnt came on. and as for the plugging the hole in the mani i was rough and got two washers just smaller than the size of the hole. one on the outside one on the inside poped a bolt and nut through it tightened it up and covered it with zorst paste. lol
-
#20the main reason for the sleeve is that the lambda has a heat element in it that gets mega hot! try to keep hold of it when you start up the car and see what happens lol.
-
#21oh well i better check its not melted anything lol
-
#22its there to aid the reading of mixture during cold start idles etc. it does get hot on its own.
the lambda only works on idle and on light load. -
#23think i better move it its sitting on top of the pipes next to the battery i just used the clip for them to hold it in place.
-
#24just make sure its not getting hot and melting anything.
i just have mine on a small plate mounted next to the bottom of the manifold. getting cool air on it all of the time. -
#25just moved it will need to make a sleeve at the week. it hadnt melted anything but better save than sorry
-
#26ill buy the propper sleeve, is a lot of money but worth it i suppose..
-
#27it will be easy to make a sleeve up. you just need to know the thread of the lambda sensor. either have someone machine one up for you, or find a nut that fits and weld the nut to a hollow tube and weld an end on the tube.
you could try and PM williams_vts, tell him i said for you to ask. he may be able to machine one for you
i know he has done them in the past, just depends on how busy he is at work.
-
#28hmmm ok ill try him, although how much would this all cost? the sleeve to buy is £15 sooo...
-
#29ask him if he can do you one first.
not sure on the cost, if he can do it, he normally does them on the side when he is not busy.
i will text and ask him now
-
#30yeah thanks mate that would be great
-
#31he can make a few up for 5 of the finest english pounds plus the delivery charge

£5 + delivery -
#32best to send him a pm saying you want one so he knows.
same with anyone else wanting one. -
#33sorted cheers mate thats mint
-
#34awesome ill beer that in mind when i get my mani and exhaust betta than 15 quid lol
-
#35so why do 00- vts decats come with a lambda hole if all that does (when you put the 2nd lambda in) is put the management light on?
seems a bit pointless putting a lambda hole in the decat at all does it not?
