so are you suggesting fiat tweak the map on every car they make?
I dont trust them,
because how can every single Car in the world running at diffrent atmospheres and temperatures require the exact same tweaks in the map?
No car is the same, all need specific alterations, if you think loads of sensors on the car and each one could be reading slightly different to the next "identical" car?
What happens is they take a random Bravo for example somewhere in the world remap it, put it into a box and sell it on.
Also tune boxes don't take into account exhausts/intakes(filters) you might of changed.
And the worst kind of "boxes", the increased response people generally feel is the sensitivity adjustment in the Fly by wire throttle increased, boost increase is tricking the ECU into false or lower boost readings.
A true remap takes all the conditions and loads then they adjust everything around this data,
Hence my car Remapped was night and day,
it pulls in 6th like it used to in 3rd, i drove down doing 43mpg and drove back doing 57.2mpg, less stress on the engine because its set up truly for the car.
It's crazy i had £50 of diesel in my tank did a 400mile round trip wife did 4trips to work and we STILL have more than 1/4 of a tank left, and by doing the maths i get 100miles more now per fill up.
