Help Needed: Custom PHF Tune for Ford Focus C-Max 1.8 – Emis

Hello everyone
I'm looking for help from an experienced tuner who can create or modify a custom PHF file (including strategy + calibration) for my 2006 Ford Focus C-Max 1.8 Duratec HE with engine code Q7DA and ECU Visteon ESU-131.

My goals with this hybrid tune:

• Pass Swedish emissions inspection (currently failed due to rich mixture)
• Improve fuel economy and throttle response (similar to a light Stage 1)
• Optimize everything for petrol-only use (I never use ethanol or E85)
• File must be flashable with FORScan 2.4.18 beta + OBDLink EX

Vehicle Information:

• Model: Ford Focus C-Max 1.8 Duratec HE
• Engine: Q7DA – 1.8L NA
• Year: 2006
• Transmission: Manual
• VIN: WF0MXXGCDM6L02165
• ECU: Visteon ESU-131
• Fuel: Petrol only (95/98 RON), no E85 ever used
• Catalytic converter: Gutted, but outer shell still present and rewelded
• O2 sensors: Both pre- and post-cat sensors installed with spacers
• Air filter: Clean OEM
• Engine: Fully rebuilt ~1000 km ago
• PCM: Adaptation reset
• No DTCs or check engine light
• Lambda at inspection: 1.03 (Passed )

Emissions test failed due to:

• CO at idle: 0.5% (limit: 0.3%)
• HC at idle: 303 ppm (limit: 200 ppm)
• CO at 2500 RPM: 0.6% (limit: 0.2%)

Current firmware in PCM:

• UHFFAA1 – 5M51-12A650-AF
• Calibration: C214/C307 1.8 Ni4 iB5, Stage 4, EU FFV
• Dated: 20.11.2006
• Downloaded from: civil.techserviceford.com

This appears to be a FlexFuel (E85-capable) calibration, but I only use petrol and it seems to run slightly rich under low load.

Modifications I’m looking for in the PHF file:

• Leaner fuel at idle and cruise (to reduce CO and HC)
• Reduce warm-up enrichment (e.g. -10%)
• Delay fuel enrichment during acceleration
• Disable or adapt post-cat O2 logic (because cat is removed)
• Remove E85/FlexFuel-related logic entirely
• Slight fuel/timing tweaks to improve throttle response and daily driving

🧰 Tools I’m using:

• FORScan 2.4.18 beta
• OBDLink EX cable
• Flashing via FORScan, so I need a PHF file with both strategy and calibration compatible with Visteon ESU-131

My questions:

• Can someone help me modify my existing PHF file with a leaner, petrol-only calibration?
• Or does anyone have a PHF file that is already tuned for this engine/ECU and petrol use?
• Any suggestions for better emissions and improved driveability?

I'm attaching the firmware files I’ve flashed so far in a ZIP archive. I can also share Live Data or logs if needed.
Thanks in advance for your support and expertise
Any help is truly appreciated!
