REMAP + DPF OFF

What is Remap + DPF Off?

Remap + DPF Off is our most popular diesel combo service, combining a professional Stage 1 ECU remap with a complete DPF (Diesel Particulate Filter) software delete in a single calibration file. Instead of ordering two separate services and flashing your ECU twice, this package delivers both modifications in one optimized file — saving you time, reducing risk, and ensuring both calibrations work together seamlessly.

The Stage 1 remap optimizes fuel injection timing, boost pressure targets, torque limiters, and rail pressure maps to extract the full potential of your engine on stock hardware. Simultaneously, the DPF delete removes all software strategies related to the particulate filter: soot loading models, active regeneration triggers, differential pressure monitoring, and post-injection fueling. The result is a cleaner, more powerful, and more reliable engine calibration.

Why Combine Remap and DPF Off?

Ordering remap and DPF Off separately means two file modifications and two flash cycles. Each flash cycle carries a small risk and takes time. More importantly, when both modifications are developed together, our engineers can optimize the remap calibration knowing the DPF restriction is removed. This means:

• Better boost response — without DPF backpressure, the turbo spools faster and the remap can take full advantage of improved exhaust flow
• Optimized fuel maps — injection timing and duration are calibrated for unrestricted exhaust, delivering cleaner combustion and more torque
• No regeneration interference — the remap never gets interrupted by DPF regeneration cycles that temporarily alter engine behavior
• Single flash operation — one read, one modified file, one write. Less time on the bench, less risk
• Cost savings — combo pricing is significantly less than ordering each service individually

What Gets Modified

The combined calibration addresses all relevant ECU maps and strategies:

Stage 1 Remap

• Fuel injection timing and duration maps
• Boost pressure target and limitation maps
• Rail pressure curves
• Torque limiter adjustments
• Smoke limiter optimization
• Throttle response improvements

DPF Delete

• Soot loading model disabled
• Active and passive regeneration removed
• Differential pressure sensor monitoring off
• Post-injection fueling strategy removed
• All DPF-related diagnostic trouble codes suppressed

Supported ECU Platforms

This combo service covers all major diesel ECU families including Bosch EDC16, EDC17, MD1, and MG1 series, Continental SID201 through SID210 and PCR2.1, Delphi DCM3.5, DCM6.2, and DCM7.1, Denso SH7058 and SH7059, and Marelli MJD6xx and MJD8xx platforms. If your ECU is not listed, contact us — we likely support it.

Performance Gains

Typical results from the Remap + DPF Off combo on common diesel engines:

• 2.0 TDI (CR) 140 HP — gains of 30-40 HP and 60-80 Nm
• 3.0 TDI V6 240 HP — gains of 40-55 HP and 80-100 Nm
• 2.0 HDi 136 HP — gains of 25-35 HP and 50-70 Nm
• 2.0 dCi 150 HP — gains of 30-40 HP and 60-80 Nm

Fuel consumption typically drops 5-15% thanks to the removal of regeneration cycles and optimized combustion efficiency.

Our Process

1. Read your ECU — extract the original file using your preferred tool via OBD, bench, or boot mode
2. Upload and specify — send us the file and select "Remap + DPF Off" as your service
3. Combined calibration — our engineers develop both the remap and DPF delete as a single integrated calibration
4. Quality verification — checksum correction and validation against known-good baselines
5. Download and flash — one file, one flash, done

Turnaround Time

Most Remap + DPF Off combo files are delivered within 30-60 minutes during business hours. The combined service is faster than ordering separately since both modifications are developed in a single session.
