Lean hiccups in cruise caused by AE?
Just got my 600's installed and started trying to dial some stuff in. I think I've got a decent handle on most of it. One thing that is bugging me... When held at a steady 4,000 to 4,500 rpm cruise down the highway I get lean spikes and the car surges... will be cruising at about 15.0 to 1 and it will shoot up to 17.4 to 1. Would my AE settings play a role in this? If not what would?
Here is my latest log.

Thanks guys.

I have a similar issue issue. What happens with mine is The ecu gets a random reading of 10,000 rpms or so... causing the rev limiter to blip.
Here is what mine looks like, i still havent solved it:

Log your Cam Angle Sensor. Mine had the same problme with the lean spike and RPM spike to 10,000 rpms during cruising. My normal logs would not always show the RPM spike but the when I logged the CAS it did. Once I saw that the CAS was not sending out a signal every now and then I replaced it and it has been fine since.
