6 wire lambda

Post by S13AW »

Not much you can do with a 6 wire. On some types there is a wire which shows inverse proportianality to lambda value, Frank Massey expalins that in one of his videos - can't remember which, or where I saw it sorry.
If you have a mind to and equipment to do it you could monitor pump current which is proportional to lambda value.
If its a bosch lsu type, there is a load of info RE: wire diagrams on the net.

You need a low current clamp something like 0 - 450mA to get good trace.

If you are able to measure current take care when looking at the rich / lean values.

There is only a very small change in current too.
