Ford Focus MK3 ST (2018 facelift) remap
I had a Revo stage one remap on my 2018 Ford Focus MK3 ST (facelift).
10,000 miles on the clock, running perfectly, I hope to gain a little extra oomph. Revo had a couple of distributors near me, so I booked it in.
The remap did provide noticeable increase in torque (giving more of a pushed back in your seat hard acceleration). Unfortunately it came at a price.
General driving was awful. Light to medium acceleration was lumpy and hesitant. For those that have experience with carburettor vehicles, it was the same sort of issue you get with really poorly adjusted or jetted carbs (full throttle from rest and the car floods and you sit there for a few seconds before the car picks up.
So I conclude that the tune was over fuelling from 1/10 to 6/10 throttle. I also deduce this from my MPG going from average of 38mpg before the Revo remap to 25mpg after the Revo remap. Their website advertises an increase in MPG not a large decrease.
Having changed the spark plugs, air filter (to a paper and then foam high flow filter), air intake system, hoses and upgraded the intercooler. I still had the issues, the car was not pleasant to drive. In fact it was verging on hazardous, passing slow vehicles (including cycles), to avoid the car baulking and minor kangarooing, I had to use 3/4 plus throttle. As well as appearing as a yob (I am approaching 60, grey hair and all), it was dangerous and if witnessed by the boys in blue, I likely would have been cautioned for dangerous or aggressive driving.
I contacted the distributor and they removed the tune and gave me a refund (not a full refund but near as dam it). Hence the two stars, the actual Revo remap is one star and that is being generous and the fact you cannot leave a review with zero stars.
