Hi,

I'm in the process of setting up the gear ratios in the AEM Infinity. I can't quite get it perfect. I'm seeing the gear indicator fluctuate especially in the higher gears. I'm on a relatively tight ratio 6spd with a shorter than stock final drive. Is this the best it's going to get? Also, is there a way to setup the gear ratio table to display when the car is cruising in Neutral? For example if the rpm is at idle while in 6th gear (i.e. Gear lever = Neutral) for it to show as N? I'm not sure if I just need to better fine tune my gear ratio table or if this is an inherent issue with the Infinity or these type of gear ratio inferred calculators.

I'm not able to upload my Infinity logs at the moment but it occurred to me I have a short clip below. You'll notice some fluctuations between 3rd, 4th, 5th gear indicator right below the "mph" in the bottom center of the display.

I was able to pull an old log. The problem is in this short gear setup the gear ratio sometimes overlaps between 2 gears. In the instance below... I have the cursor showing Gear = 2.1 but the car was in 3rd gear here with the current gear ratio range in 3rd gear between 61 and 99. If I try say a range of 61-98 then I sometimes get 98 values while in 2nd gear which makes 2nd gear finicky.

Is this as good as it gets?
