SCR DPF EGR Off for BCI

Restore Performance with File Services for BCI Vehicles

BCI buses like the PROMA, powered by an 8.9L Cummins engine and managed via the CM2350A ECU, are reliable machines built for efficiency — but emissions systems like EGR, DPF, and AdBlue (DEF) often create more problems than they solve. These systems can cause performance drops, fuel overconsumption, and constant regeneration issues, especially in demanding city or long-haul conditions.

Our specialized File Services for BCI allow for safe and effective emission system removal directly through the ECU. With our tuning solutions, your vehicle regains full engine power, improved throttle response, and lower operating costs — no more limp mode or annoying fault codes.

By removing restrictive emission components on BCI PROMA models, you get the reliability and power the engine was truly designed to deliver.

All models of the brand might not be listed due to the extensive scope of work, but we can operate on 95% of the brand's fleet.
