ECU Flash - AMK vs Hitachi Compressor

[cannondale900]

I've recently been having some issues with 92k mile 2015 LR4 suspension sagging after car is left sitting. Just started diagnosing the issue this past weekend. Haven't pulled the fuse/relay yet. No suspension fault errors on cluster or IIDTool to date.

Checked compressor to see if I had AMK or Hitachi. Removed compressor cover and see AMK compressor. Using the IIDTool I checked to see which software was installed for the suspension and it said Hitachi. I flashed suspension ECU to be AMK and now the compressor runs non-stop. The only time the compressor doesn't run is when I lower the car. After the car is lowered, the compressor starts running again.

Flashed back to Hitachi. Now I'm getting suspension faults left and right.

Anyone have similar issues?

Are you the first owner? If not, how long have you owned it? Seems wild that the software would have been wrong the whole time.

Maybe try contacting Gap Diagnostic and see if they have any helpful info.
