Looking at getting my 3.2 remapped. Found a decent company in Nottingham called dyno tech who seem like they know their stuff.
Their remap offers upto a 12bhp increase and 20Nm torque.
I'm not overly fussed about more power etc but am more interested in a smoother drive with maybe a bit better economy.
Has anyone here had their 3.2 remapped? And what sort of difference does it make for driving pleasure, and is there anything to worry about it damaging (gearbox/clutch etc)
I had my 3.2 Brera remapped by QuantumTuning.co.uk dealer Energy Tuning Ltd in the North East a coiple of months ago.
Their kit cannot read the Bosch ecu via the obd port but could write the tuning file. But this is risky as you have no backup copy of the original file to put back if you want/need to.
So Darren removed the ecu (dead easy on the Brera) and did it directly on the bench which means he has a backup.
I had a few minor issues when I refitted the ecu but this was due to having to reconnect the battery with no engine ecu, to get the windows to close. (the windows lost their position) Their was a VDC unavailable message initially but this cured itself and in any case MES works normally and I didn't have to do a proxy alignment and no other issues have cropped up.
As for the benefits: Quantum claim similar results to those quote here*, and you might be hard pushed to notice any actual overall performance improvement without a stop watch. (*ie not enough to worry the clutch or transmission)
However, 2nd and 3rd gear acceleration feels a lot more like you'd expect from 3.2L and needs 4 driven wheels unless the road is bone dry.
It is also smoother and more responsive below 3000rpm (pulls from below 1000rpm in any gear without protest)
Mpg was hovering around 22mpg, and the average consumption display rarely exceeded 23. Now its 10% better and the average reading has been upto 27 on many occasions. However the weather is warmer and I also use Millers petrol Ecomax so I can't claim the remap is responsible for all of the 10% saving.
I think much better results are possible from a remap but it needs someone who can alter the cam timing if its even possible in the firmware as I think its this that determines the shape of the torque curve. So it should be possible to get a lot more low & mid torque without compromising the top end. When I saw the obviously artificial factory torque curve it made me wonder whether Alfa have had to restrict the torque below 3000rpm to avoid transmission reliability issues.
