hi,anybody know the thread size of a lsu 4.2 sensor?does make a stainless boss which i can weld on?is this wideband?
thanks andy
bought bosses from 'Nick Skidmore' who is on here as for the tread size M18 but could be wrong
Stainless with bung .
Send him a U2U

M18x1.5 
It is wideband, and it's a standard Lambda sensor thread (whatever that is!). You do know a wideband has to be used with a suitable controller
such as the LC-1? You can't just plug it into your ECU.
Edit: There may be some ECUs with built-in controllers but if so they're not the norm.

thanks for all that,
i,m using a 1.8 raceline zetec with jenveys
and im thinking of using megasquirt.the sensor has a 6 pin plug on it with a little blackbox plugged into that,is this the lc-1 or will megasquirt
sort that?
That probably is the lc1. Should look like this:

I've got one.
M18 x 1.5 x 17mm long.
It's a left over from when I made my wish bones

(p.s. I'm 40 mins from Cambridge)
i don't have the wiring as shown in photo
after it plugs together i.e the long black bit.
is that the lc1
thanks
Yes, the long black case is the LC-1 controller. That then gives a (programmable) variable voltage output (usually 0v = 10:1 AFR, 5v = 20:1 AFR) to
your ECU.
I bought mine from diyautotune.com and had it shipped over from the states. Even with import tax it was the cheapest option at the time with the
current exchange rate.
