Per Cylinder lambda logging
How can on log individual cylinder lambda?
I believe #2 and #3 go lean and would like to (possibly) be able to log and manage appropriately.

I have actualy done this on our dyno
We made a special plate to sandwhich between the exhaust manifold and the head, the plate sampled off a bit of exhaust gas from easch ex runner.
We then piped that to 4 seperate lambda sensors run by 4 of our PLM's
All cylinders within 5% or better from memory whilst under load. (above 100kpa)
At idle and cruise cylinders 2 and 3 leaner than the rest.
I will try and find the log file of the results.
This was with stock set up thou.

Hi I founds some pics of the plate etc
We piped from the plate to an exhaust manifold where we already had 1 lambda per pipe welded in.
It was a bit ugly but worked fine on the dyno.
If you wanted to do this you could actually make just 1 sample pipe up and measure each cylinder 1 at a time. 4 runs and you would have your info.

Thanks one at a time was exactly what I was thinking. 4 PLMs is a bit much for just me.
Do you know how thinck that was and what size fittings?
Need to see if I can find someone to make a plate or I might be able to pull this off myself with some aluminum.
