Hello,

I have problem with my harvester Deutz Fahr with SISU engine.

It has 3 selection of REV speed. Low, medium and high.

Low rpm is for turn on ENGINE,
Medium rpm for drive.
Hight rpm is for work (harvesting)

On Low and medium rpm enigne work good.
But when the switch is set on HIGH speed, engine cant reach it.
Any fault code on diagnostic light.

Do you have any idea for this ??

It is EDC7 ecu. i think about delete LIMP mode or copy operational parameters from high rpm to medium rpm. Can it work ?


Best regards
