Please only post in this thread if directly related to the software release. It is not the place to request features.

I just updated to 4.7.7.0, and it appears that the compare calibration function is still not working right. In the image, the identical values shown are from two identical calibrations, but it still says there are differences in Injector phase (WOT). This is the same behavior I saw in versions prior to 4.7.7

Post the calibrations you are comparing.

Only does it when comparing an old calibration to one you just made.

I played around with it and I'm confident you can recreate it. Not sure if it happens for all new calibrations, or just mine so here are the exact settings for the one I was using.

New Calibration
Model: Accord 2.0T (2018+) US
Vehicle: Accord 2.0T 2018+ AT
Calibration Name: Accord-Turbo-2.0-2018-AT-Flex
Keep Flex Fuel Enabled
Closed Loop: Uncheck 2nd o2 sensor

Save the calibration
Close it

Create another one the same exact way as above
Compare it to the one you saved.

I guarantee it will say there are differences when there aren't.

Save the calibrations before comparing as there are subtle rounding changes made when saving on some tables.

Bugs I have noticed using a FK8 calibration on this version (4.7.7)

1- VTC - intake cam (spool cold) - 3D table render is off to the right and 70% NOT visible.

2- Instant live tuning table select - you can click "select all" and it will use all tables to fill memory, but the actual bug is its calculation method
- will say 100% full, but "DESELECT" exhaust cam and will say memory full from 100%. deselecting random items will go from 93% to 100%

3- Boost by gear by tune - Order of Maps is 1, 2, 3, 5, 4 ( 5 superceeds 4)
