About this file
What this Stage 1 file is
This is a Stage 1 tune of the factory calibration of the 2003 MB Citaro EVOBus O 530 G 18m (257 kW, 350 hp), for its Temic ECU with software OM457hLA.III-5-00 56E and ECU number OM457HLA.III-5-00. Stage 1 is software only: the car keeps its standard turbo, injectors, intercooler and exhaust.
Stage 1 on this engine raises the injected fuel, the boost and the rail pressure and lifts the torque limiters, within what the standard turbo, injectors and clutch hold. The smoke limiter follows the new airflow, so a healthy engine pulls harder without black smoke.
The file is listed for the 257 kW, 350 hp version of the MB Citaro EVOBus O 530 G 18m. Check the power on your car's papers: the same model was sold with several engines, each with its own file.
For software OM457hLA.III-5-00 56E of the MB Citaro EVOBus O 530 G 18m we sell the original and Stage 1, each made from the same original read. Every file downloads straight after payment.
Read the Temic ECU with your usual tool and keep the read: compare its hardware and software numbers with the ones on this page before you write the file.
EGR off, DTC off and speed limiter (Vmax) off can be added to this file on request, for off-road and competition use: send us your read through our file service and our engineers add them (any file £50, from £30 in packs).
Software OM457hLA.III-5-00 56E is the calibration inside the Temic ECU. ECU number OM457HLA.III-5-00 is how this Temic ECU identifies itself.

A Temic ECU with software OM457hLA.III-5-00 56E and ECU number OM457HLA.III-5-00. Check those numbers in your read before you write it; another software number needs another file, which our engineers can build from your read.
