Wow! I drive a 2019 Fiat Ducato Campervan. Andy arrived this morning and straight away got on with the job of remapping the engine. Just back from a drive to Hastings with a couple of hills along the way, the van just flew up them without having to change down a gear or two, much much better!! Thoroughly professional service, totally recommend RubyTune Ltd to have your ECU remapped. And by the way Andy is a lovely chap nothing was to much trouble, a 5 Star service! Thank you Andy! Kind Regards Michel (Mac)

Andy remapped my Ducato-based Hymer Motorhome a couple of weeks ago, I had a 25 min test drive and i noticed a difference in 3rd and 4th gear, lots more torque.
Today i had a trip, 4 hours driving around the M25 then up the M40, wow, what a difference. used to show 24-25 mpg, once even reached the dizzy heights of 27.2 mpg. Today i was averaging 29 mpg and even saw 32 mpg at one stage. The torque is much stronger allowing much faster overtakes, and less gear changing. My wife thought that the journey was much smoother than normal.
So a big thank you to Andy and RubyTune.


How is this possible? Let’s consider the Fiat Ducato drivetrain, commonly used in many motorhomes. The latest 2.2 Multijet is offered in 120hp, 140hp, and 180hp versions directly from the factory. It’s the same engine with various software setups in the ECU (engine control unit). Our sophisticated programming tools allow us to manipulate this software just like the manufacturers, effectively releasing the hidden power that’s already available.

I’m now in Spain with the Tag Axel Motorhome that you remapped, more power on the hills, less gear changes, and an improvement in MPG!
