Basicly my question is dose a E36 M3 evo 3.2 use zirconia or Titania lambda sensors??
My 2.8 engine used Titania with the yellow, red, black and white wires. When my s50b32 came on its pallet the wires for the lambdas were cut off i have grafted new conectors onto them but Im looking to buy some universal sensors and graft plugs on them to get msyelf going howevere i dont know what kind to buy. Some places say they are Titania while every wibsite i see says the normal 4 wire zirconia sensors work (grey,black, white white)
If no one knows the answer perhaps a lovely M3 owner can go look at the colours of the wires on there lambda cables!?
(grey,black, whitem white) zirconia
(yellow, red, black, white) Titania
I dont want to spend money on the wrong things :(
