Damn stupid problem happened again this morning! Still waiting for the ICV problem to be fixed. Parts are in but apparently it takes a whole day if not two to replace the ICV, hose and clamps and update the software! I've had quicker Commodore 64 tape drives! Anyway, for the benefit of everyone I have taken screenshots so you can ID the problem should it happen to you........
Note how revs are limited to 5000 rpm
