In 'simple terms' the primary controls fuelling through feedback in real time if the AFR (air fuel ratio) is rich or lean and adjusts - so the mugen ECU definitely needs this or the car would run like a bag of crap.

The secondary in simple terms just checks if the CAT is working/is still there.

Lastly look up 'walker' o2 sensors by me and 'grittyshaker'

I dont know which one you need, but i think the secondary is female.

yeh its the sensor that directly plugs into the cat. that im having trouble with. just find it strange that ive ordered 2 of these and they have both ended up with male ends?

I have a Walker one for sale, as I never got round to fitting it before the car was written off. Somebody showed interest in it a few weeks ago, and I've been waiting for a payment since then.

If you want it it's £50 delivered (cost me about £70), but I'll need to email the other guy before we do anything, as I did specify that there was no rush for him to get his payment sorted.

EDIT: PM me if interested, as I'm not lurking as much as I used to.

If its the one in the decat then its the secondary one, which grittyshaker has for sale.

Bargain if you ask me as they are about £65-70 delivered.
