Hopa Auxiliary Control Unit: Installation Guide

Hello,

Approximately 15 years ago, I installed an auxiliary control unit from Hopa in my BMW 525tds. This control unit is adjustable using 3 adjustment screws.

Unfortunately, the engine failed due to a faulty thermostat, and our diesel vehicle received a replacement engine. Now, the auxiliary control unit needs to be adjusted for the new engine, but I no longer have the adjustment instructions.

Does anyone have any experience with these Hopa tax meters, or perhaps a manual for them?

Thank you in advance.

Best regards, Bernd.
