09–11 E90 335D / 09–13 E70 X5 35D M57N2 EDC17CP09 CUSTOM DIESEL TUNE (S1/S2/S3)

BMW 335d (E90) and X5 xDrive35d (E70) custom EDC17CP09 diesel ECU tuning by Poverty Built. Stage 1 (OEM+ with emissions present), Stage 2 (track/off‑road deletes and flow hardware), and Stage 3 (enhanced track calibration) deliver strong, repeatable torque with smooth drivability and conservative, data‑driven calibration for daily and track builds.

Fits:

• 2009–2011 BMW E90 335d — M57N2, EDC17CP09 (USDM)

• 2009–2013 BMW E70 X5 xDrive35d — M57N2, EDC17CP09 (USDM)

What Poverty Built does for this platform: Poverty Built delivers OEM manners with real‑world torque. For M57N2 + EDC17CP09 we calibrate:

• Driver’s wish → torque model → torque limiters by gear

• VNT/boost control and air‑charge modeling

• Rail pressure, injector quantity (IQ), and smoke control

• Plausibility/diagnostics alignment so changes are reflected in the ECU’s logic

• Thermal protection and safeguards retained where appropriate

• Optional Vmax (top‑speed limiter)

STAGES, GAINS & PRICING

(Gains depend on health, fuel, altitude, hardware; we quote conservative deltas.)

STAGE 1 — OEM+ (Emissions Present)

• Gains: ~+55–65 hp / +90–120 lb‑ft

• Price: $280

• Hardware: Stock emissions hardware present and healthy.

• What we change: Driver’s wish, torque model/limiters, smoke limiters, boost/rail targets, and thermal thresholds. Emissions systems remain active.

• Use: Street.

STAGE 2 — Track/Off‑Road (Deletes Supported)

• Gains: ~+80–110 hp / +150–220 lb‑ft

• Price: $340

• Hardware: Track/off‑road exhaust with DPF/SCR/EGR removed, intercooler recommended, swirl flap blanks, tight charge system, healthy CP3 and injectors.

• What we change: All S1 items plus recalibration for lower backpressure/increased flow, refined smoke control for your hardware, plausibility updates, and torque‑by‑gear for transmission harmony.

• Use: Off‑road/closed course only when emissions are removed.

STAGE 3 — Enhanced Track Calibration (Custom)

• Gains: Hardware‑dependent; typically at the upper end of Stage 2 with more aggressive torque delivery and sustained‑load/EGT management.

• Price: $420 (~25% under typical big‑name custom packages)

• Hardware: Same hardware as Stage 2 (track/off‑road exhaust, intercooler recommended), robust fuel supply recommended; transmission tune recommended.

• What we change: More assertive yet controlled smoke limiters, refined boost and rail ramps, sustained high‑load thermal management, torque shaping by gear, targeted DTC strategy aligned to hardware, and enhanced shift cooperation with the transmission.

• Use: Off‑road/closed course only when emissions are removed.

COMMON SOLUTIONS (Diesel)

We implement targeted logic/DTC handling so the vehicle remains diagnosable. We do not disable safety‑critical monitors.

• EGR Off / EGR Throttle Off (off‑road)

• DPF Off with differential pressure & EGT strategy alignment (off‑road)

• SCR/DEF (AdBlue) Off with NOx sensor logic alignment (off‑road)

• Swirl flap solutions (calibration + hardware recommendation)

• MAF/MAP plausibility & exhaust temp/pressure strategies adjusted to hardware

• Torque monitoring & limiters by gear harmonized for transmission health

• Vmax optional

WHAT YOU GET

• Smooth part‑throttle manners; strong, repeatable torque; controlled smoke

• Transmission‑aware torque delivery (pair with a transmission tune for higher stages)

• Revisions with logs until it’s dialed (boost/MAF/MAP, rail pressure, IQ, temps)

RECOMMENDED SUPPORTING MODS

• Stage 1: Fresh filters, no leaks, healthy sensors/emissions hardware

• Stage 2: Track/off‑road exhaust; intercooler; tight charge system; robust lift/HPFP as needed

• Stage 3: Same as Stage 2; consider upgraded lift supply for heavy use; transmission tune recommended
