RS2 Questions
When I overlay two or more laps on the Measures Graph I automatically get a "time delta" graph at the bottom of the screen. Sometimes this is useful and sometimes it is just taking up room on the screen. Is there a way to turn this off and on? After much trial and error I finally have the Calculated Gear operating properly. I'm trying to find the optimal shift point from 4th to 5th at the top of the esses at Watkins Glen and have some data where I "Short Shift" or run 4th to redline. Is Calculated Gear accurate enough to use in this decision? Is there another way?

To turn off the time compare, click the wrench button top right of the measures window. Then uncheck the box for time compare. This is also where you turn the channel tags, min/max, and average information on and off.
For gear, you can do it in the car or with a math channel. The one that AiM uses is
gear(ECU_RPM, GPS_Speed, 1, 4)
You have to make sure your channel names are put in the above formula. They should come out the same and are easy to check when you compare them to the RPM graph.

any conclusions yet?
My gut says redline for your car should always be better for two reasons: (1) torque multiplication of transmission (1.13 vs 0.95) should give you ~25% more torque to the wheels by staying in 4 longer and (2) the additional hp at redline assuming your car is not seeing a large drop off prior to RL. HP = mass x acceleration x velocity. So all things being equal (velocity is the same for both gears at instant of shift) then acceleration is maximum at higher HP.
I have an E46 M3, but RWHP and ratios seem to be very similar for our cars (with my power mods). My redline is 8200 and I was hitting 7800 (113 mph) just before 3. I shifted there because I didn't want to take my hands off wheel again in the esses themselves.
I have AIM data that I'd be willing to exchange with you.
