Hauling a caravan or trailer can turn your weekend escape into a struggle against sluggish acceleration, high engine temperatures and poor fuel economy.
A purpose-built ECU remap reprograms your engine for towing—giving you the confidence to tow heavier loads without compromise.
Benefits of a Custom Remap for Towing
- Extra Low-End Torque: Towing maps boost torque down low (1,200–2,000 rpm), so you pull away smoothly even on steep exits or unladen hills.
- Smoother Throttle Response: Throttle mapping removes hesitation and softens spikes, making gear changes seamless under load.
- Engine Protection: Revised ignition timing and boost control reduce exhaust gas temperatures, protecting your turbo and pistons on long hauls.
- Better Fuel Use: Holding higher gears longer and reducing lugging can help cut fuel use on mixed towing routes.
How We Tune for Towing Loads
Our technicians start with a full diagnostic scan using Autotuner or CMD Flash.
We read your stock map, then apply bespoke edits:
- Torque Targeting: Raise low-rev torque tables by 15–25 % within factory safety margins.
- Boost Management: Stabilise turbo pressure under sustained load to avoid spikes.
- Ignition Safety: Retard timing slightly at high load to control exhaust gas temperature.
- Throttle Smoothing: Refine throttle curve for predictable power application when towing.
Finally, we run post-flash diagnostics and a road test to confirm performance and reliability.
Example: Towing a Caravan
| Vehicle | Metric | Stock | Towing Remap |
|---|---|---|---|
| Ford Transit Custom 2.0 TDCi | Torque | 360 Nm @ 1,750 rpm | 410 Nm @ 1,600 rpm |
| Ford Transit Custom 2.0 TDCi | 0–30 mph | 8.5 s | 6.9 s |
With a 1.5 T caravan behind, the extra low-down torque means stronger pull on hills and fewer gear changes.
Mobile vs Garage for Towing Remaps
Whether you choose our mobile service or workshop visit, you get the same towing-focused map:
- Mobile Remap: We come to your driveway across Staffordshire, Cheshire East and Leek—ideal when your trailer is already hitched.
- Garage Remap: Visit our Fenton workshop for a full diagnostic and power check and combine with an oil service or DPF clean: DPF Cleaning.
Frequently Asked Questions
Will a towing remap void my warranty?
No. We save your original map and can restore it for dealer visits, then re-flash your towing tune afterward.
Can I tow any trailer or caravan?
Yes—towing maps suit a wide range of loads.
Let us know your trailer’s weight and gearing so we tailor torque tables precisely.
How long does towing remap take?
Mobile sessions take around 2 hours including diagnostics and a road test.
Garage sessions with extra checks take about 3 hours.
