Thanks for the reply.

I can't presume OLSD because I don't know what OLSD means! :)

Still trying to get my head around why "The INT has settled hovering around 128 where it's happy." Why is it happy with a BLM of 117 rather than 128?

So the INT only tries to move the BLM value if it goes above or below 128 by 5, that by itself makes sense. As above, not sure why it seems happy with the 117 BLM?

I had figured that it was about 8-10% Rich from the 117 BLM, thanks for the confirmation though.
Since that log I've reduced the VE table by 5%, I haven't had a chance to test it out yet.

Cheers,
Andrew
