The Ford Ranger is a common sight on trade and farm drives around Tameside, the High Peak and Saddleworth, often towing or carrying a full load. Alientech has published a case history on the 205 hp Ranger 2.0 TDCi EcoBlue Bi-Turbo, which uses the Continental SID213 ECU. We have picked out the parts that matter to Ranger owners and the way a careful remap should be done.
The vehicle
- Ford Ranger 2.0 TDCi EcoBlue Bi-Turbo, 4-cylinder diesel, 1996 cc
- Rated at 205 hp (151 kW) and 488 Nm
- ECU: Continental SID213
- Goal: more torque and a stronger, wider spread of power under full load
Lesson 1: measure before you change anything
The workshop started by measuring the standard vehicle with an on-road power test built into KESS3. It came out at about 201 hp and 488 Nm. That gives a real baseline to compare against afterwards, rather than relying on a brochure figure. It also shows up a vehicle that is down on power before tuning, which usually points to a fault that should be fixed first.
Lesson 2: fuel, air and boost have to work together
The calibration changes were made in software only, with no mechanical parts changed. The torque limiters were raised towards the target. Fuel delivery was increased, and boost and rail pressure were adjusted so the engine had enough air and fuel pressure to support it.
Alientech points out that the lambda (oxygen sensor) control stops the air-fuel ratio dropping below a set threshold, which limits how much extra fuel can be added. In other words, a good diesel calibration is a balance: adding fuel without the air to burn it cleanly just makes smoke and heat. This is why we prefer a measured, conservative map over chasing the biggest number.
Lesson 3: check the result
A second on-road test after the work recorded about 241 hp and 601 Nm in Alientech's example, with a fuller torque curve across the rev range. The customer is quoted as saying the Ranger has "much more pulling power, especially when torque is needed at low and mid-range rpm".
These are the figures from one vehicle in Alientech's test. Results vary with the vehicle's condition, software version and fuel, and we will only give you an estimate once we have checked your truck.
What this means for you
- If you tow or carry heavy loads, low and mid-range torque is usually what makes the biggest difference day to day.
- A proper job starts with a diagnostic scan and a baseline, so you know the vehicle is healthy and what has really changed.
- Good tuning stays within the engine's air and smoke limits. We do not add fuel the engine cannot use cleanly.
- Your original software is kept, so the vehicle can be returned to standard.
- Tell your insurer about any modification.
The Alientech case study also described changes made for off-road use. We have left those out. RemapIQ is diagnostics-led, and some modifications are for off-road or competition use only and are not legal on UK public roads.
