Hey everyone, the purpose of this thread is to shed some light on Eurodyne Maestro for the 3.0T. Even months after its been released there is very little information available online and from what i can tell, very few people using it at an amateur level.
Many of you may have seen logs in the VCDS logs thread and read comments about how "unfinished" Eurodynes tunes are on the 3.0t. The logs that where posted where less than ideal and the cars where known to generally be slower than other tuned cars. The way I look at it, Eurodynes tunes where always designed to be base maps that where good enough to then be tailored to your car/setup/climate through Maestro.
I am taking to this with a slow and cautious approach since I am by no means an expert and this car is my daily so I'm not chasing 1/4 mile records but I feel like others who are pushing the limits could use this to get the more extreme setups perfectly dialled in. Along with making changes to the expected maps you can also disable fault codes( if you get rid of your Cats or secondary air injection for example). I haven't changed much so far, only brought down full load lambda and disabled p0420 and 0430 from my gutted cats but it seems fairly straight forward. You can also manipulate the charge air cooling pump to command 100% duty, change the vehicle max speed limiter, change torque limiter by gear, change the rev limiter etc.
One of my initial concerns was that when i flashed to stage 2 the process took 15-20 mins to flash and having to hook up a battery charger and wait that long every time i wanted to make a change to my maps would be very annoying. When I made changes to my full load enrichment map the updated map was flashed to the car in around 1min 20 seconds. This will be great when I take my car to the drag strip and can do repeated logs and adjustments from pass to pass.
I will update this post as I play around with the program and learn more. If anyone is familiar with tuning and can offer advice I already have a few questions about some of the maps but I will email Eurodyne to ask them to update the map descriptions when they get a chance too.

The photo doesnt allow me to show the full map names so ive listed them as well,
diagnostics:
---- Fault codes OBD2 Failure class 1
Ignition timing:
---- Max allowable EGT for spark retard control
Fuelling:
---- Temperature to activate the catalyst overheating controller
---- Temperature setpoint of the catalyst overheating controller
---- Maximum exhaust gas temperature Above which LSH switched off
---- Maximum threshold for exhaust gas temperatures at the lambda sensor downstream catalyst
---- Maximum temperature of the catalyst to carry out the plausibility test
---- Maximum threshold for modelled catalyst temperature under dynamic conditions
---- Lambda map for interpolation on ignition angle
---- Lambda full load enrichment
---- Fuel pressure setpoint
Limiters:
---- Vehicle speed limiter, km/hr
---- Rev limiter
---- Rev limiter 2
---- Maximum reference indicated engine torque
---- Maximum allowed torque at clutch
---- Maximum duty for intercooler coolant pump
---- Intercooler pump duty limiter
---- Minimum duty for intercooler coolant pump
Timing:
---- Basic minimum ignition angle
---- Ignition timing (reference) cam pos 1
---- Ignition timing (reference) cam pos 2
---- Ignition timing (reference) cam pos 3
Torque control:
---- Supercharger basic volume flow
---- Maximum intake air of the engine at standardized ambient pressure for different valve lifts
---- Maximum intake manifold pressure for MAF_SP limitation (for engine protection)
---- Maximum allowed pressure MAP for allow load tps check with RFP controller
---- Limitation of supercharger PQ
---- Setpoint mass air flow depending on slow torque setpoint
