Siemens MS43 Extended Load Limit

Siemens MS43 normally has a load limit of 1389mg per stroke which is more than enough for all NA and most boosted applications.

Although, when using smaller or very efficient turbochargers you can easily exceed this limit in the mid engine speed area, or with a big compressor housing even at higher engine speeds.

This is VERY dangerous and causes the ECU to enter an unstable state or even to reset. You don't want this to happen at 1.5bar boost and the engine spinning 7000rpm.

Therefore we created a special binary where we double this limit to 2778mg per stroke.
