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 cuts fuel consumption by up to 10 % 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—mobile or on our rolling road—to confirm performance and reliability.
Real-World Example: Caravan Towing in Staffordshire
| 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 | MPG (towing) | 24 MPG | 27 MPG |
| Ford Transit Custom 2.0 TDCi | 0–30 mph | 8.5 s | 6.9 s |
On a recent mobile tune in Uttoxeter, a customer towing a 1.5 T caravan saw a 20 % torque boost and a 3 MPG gain—enough to save £15 on fuel for a 200-mile trip.
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 Hanley workshop for a rolling-road 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 dyno verification take about 3 hours.
