Very impressive system considering its completely unmapable and constatnt fire.

Quite quircky if DIYers piss about with it, but for those of us who actually understand it totally its easy to get right and keep right.

The BIGGESt issue with calibration comes from teh fact that even a dipstick seal or worn crank main oil seal can cause it to run rough, not to mention a blown sump seal, rockert gasket or badly fitting oil filler cap.
