Hi Stuart
Can you scope the Lambda sensors along with the MAF doing the same test.
The MAF output seems to be better in this capture I wonder what the lambda sensors were reading during this test.
Does your live data provide you with fuel trims?
If you can, graph LT fuel trims, ST fuel trims for both banks.
Lambdas for both banks.
MAF and throttlposition.
