MSD80 to MSD81 upgrade
MSD80 DMEs suffer from frequent MOSFETs and PSUs failures, causing misfires on one or more cylinders. Car will often have following codes stored in engine control module: 30BA, 30BB, 2E30, 2E31, 2E32, 2E33, 2E34, and 2E35. It is recommended to replace injectors, coils and spark plugs on affected or all cylinders. Many times DME itself will need to be replaced as well. If you replacing MSD80 DME for these and other issues, consider upgrading it to MSD81, which has better components and is much more reliable than MSD80. Upgrade from MSD80 to MSD81 will require adding matching option to your cloning service.
