Does anyone know by which procedure it is possible to raise max rpm in CM850 8.9 ?
Engine is packaged in a TigerCat forestry machine. Operator complains that machine would be more flexible to operate if max rpms could be raised by 100-150. Currently max rpm is set at 2100. These engines run at 2250 in tractors. I have tried looking at parameters with INSITE but no luck there. Can changes be made with Calterm ? If so, does someone know exactly how ?

Thanks and have a good day

in some models only online with module others offline , post the calibration or send pm .
