Engine type : |
R 42 value (safety function, higher faster boost drop on knocking !) |
R 42 colour rings |
R 138 Value (if higher, engine overall noise tolerance higher until boost drop ) |
R 138 Colour rings |
P 03 Value (if higher, max.boost higher around 3500 rpm) |
P 02 Value (adjusts value APC sese from pressure transducer, higher - higher up rev boost) |
