STEINBAUER technology
Additional usable power without permanently rewriting the ECU.
STEINBAUER works alongside the original engine management system. The module uses application-specific injection-duration optimisation while leaving the original ECU software in place.
- No permanent ECU remap
- No common-rail pressure increase
- No change to injection timing
- Factory ECU safety strategies remain active
- Removable hardware solution
- UK installation and technical support
Questions about Sisu 84CTA 8.4L tuning
Frequently asked questions.
Can a AGCO Sisu Power 84CTA 8.4L 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 Sisu 84CTA 8.4L 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 Sisu 84CTA 8.4L?
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.
