ECU Upgrades

The S4 and M3 are quite different. Are you sure you want a more tamed animal? You may be disappointed.

Alternatively you may lap up the ability to use more of the power more of the time.

p.s. Do you know if the tip box can handle 400bhp and all the torque?

[Gareth]

Should be able to handle the Stage III really.....isn't the same 'box as the RS6??

Plus there are a number of Audi dealers now who are happy to sell AmD modded cars with their own Audi warranty to cover the customer.

What performance hike has your stage 1 - 2 - 3 made? Mainly looking at 0-60 and torque...

[Scotty]

0-60 - I don't know. At some point I'll get it on the 1/4 mile and find out that plus run times.

Torque went from
Standard at 3259rpm - 324lb-ft/440Nm

to Stage 3 at 3366rpm - 375lb-ft/509Nm

BHP went from
Standard at 6383rpm - 337Bhp/251KW/342PS

to Stage 3 at 6639rpm - 395Bhp/295KW/401PS

Here's the graphs. A bit small but you'll get the idea/shape.
