After I did the top engine rebuild, I cut up some hose, fittings and clamps to make it easier to remove the SAI plumbing.
I'm am not one to throw money at a problem but if you never replaced the Crankshaft Position Sensor, replace it now with a Bosch ERR-7354 unit.
If that didn't cure your problem, at least you replaced it for a new one since it will eventually go bad. Keep the old CPS as a back up.
Yes. If you have Mini/BMW/Rolls Royce software already on your Foxwell, you pay an additional $60 (?) to download the Land Rover/Jaguar software for it.
I think you can add up to 5 car manufacturers on the Foxwell NT510, NT520 and NT530.
