Questions about Perkins 1104D-44T tuning

Frequently asked questions.

Can a Perkins 1104D-44T engine be tuned with STEINBAUER?

Yes, where a matching STEINBAUER application has been developed for the exact machine, engine management system and factory power level. Use the application list on this page to identify a compatible application.

Is every Perkins 1104D-44T engine the same?

No. Engines within the same family can exist in different generations, emissions stages, injection systems and factory power ratings. The correct STEINBAUER part number depends on the exact application.

How much extra power is available on a Perkins 1104D-44T?

The increase depends on the exact application. STEINBAUER calibrations are developed for the individual engine, vehicle or machine and published performance data should always be checked on the exact application page.

Does STEINBAUER remap the original ECU?

No. The STEINBAUER module works alongside the factory engine management system without permanently rewriting the original ECU software.

Does STEINBAUER increase common-rail pressure?

No. STEINBAUER performance is achieved through application-specific injection-duration optimisation rather than increasing common-rail pressure.

Can the STEINBAUER module be removed?

Yes. The module is a removable hardware solution. Installation method varies by application, and registered customers and dealers can access available installation guides and videos.
