well I've been playing with OLSD so currently my AFR is like 16.5 at cruise, low load and the total advance is around 40*. yes it is jumpy. the truck computer uses a bunch of different factors to create a "final spark" number if you will.

At the time I first noticed that the timing would go way out to 45* at highway cruise I was basically stock, closed loop with MAF. maybe a few basic VE edits (in addition to new injectors) to get my LTFTs in line.
