JGS4X4 carried out a monster remap on a Fiat Ducato motor home. When the owner bought the vehicle into the workshop, it came fitted with a crude ‘piggyback’ tuning box that simply plugged into the fuel rail pressure sensor. So instead of offering a proper remap, it simply fooled the ECU into raising the fuel rail pressure. Our JGS4X4 technician removed the piggyback box and carried out a proper ECU remap.
Immediately the owner noticed a big improvement in the low down torque and pulling power! The motor home is now happy to cruise in top gear at motorway speeds whereas before it struggled on the slightest hill to maintain speeds.
