Daft question, but is it a lamba equipped L8 in the first place?

If so do you not have the loom from that car it was in?

I want to run closed loop in my car and is a 2wd, so i thought it would need xtra wiring to connect it to the ecu.

Is that pin the same for the RP Labs then Nick?

As I assume it would use the standard layout?!


Cause thats on my list of things to do soon, although i need to get another lambda boss into my exhaust first as i would sooner use a narrow sensor than the "pretend" narrow band from my wideband setup

Cool

Ive got the coilpacks to wire in soon as well.

Trouble is, once i do that, its not so easy to just swap back to my L8 like im doing at the moment if im using the car to go far as i havent got the map finished yet!

Although i guess for now i could leave the dizzy and coil in and just put the coilpack in as well!

On my version its just narrow band.

I believe nikola either has developed or is developing wideband mapping though with target AFR's etc, but i dont think any of the current ones do it.

I wouldnt want to anyway TBH mate, im quite happy with narrow band for what i do

true because ull only need closed loop part throttle and up to 3000/3250 rpm so that makes sense
