XU10J4RS Idle AFR

[jammapic]

I would expect it to cycle around the stoich mark once fully warmed up and gone open loop..

You should see it cycle above and below stoich as it trims with the Lambda...

But it does have to be up to FULL temperature to go open loop - before then - look at your map and see where it's sitting?

Don't run lambda mate, it's crap for drivability with the bodies on. No idle control either.

'6 engines seem to like to sit a touch rich at idle from my findings.
