information overload   all these map changes are in the evening and a run on the way to the office so apart from the weekends I cannot make a load of changes and runs.

I have done a run after applying the LDRAPP Tool changes based on the current setup I have (I have read other people only going to 30-40 WGDC)  now this is not hitting the max limit I set now which is excellent, and I reduced the timing advance in the 130-191 Load 4500-5500 by 5 degrees this previously was on the knock limit but now virtually nothing - which is good I will push it forwards a little bit more.

when you say no point in going over 1.5bar is this because the damage / risk is raised for very little benefit?  there are K04 Hybrids hitting 400BHP nowadays (this one obviously wont) but currently I am only at the same level I was with a stage 2 map + 80mm intake, air filter, downpipe, FMIC, stock turbo, stock rods, stock injectors - if you are suggesting a hybrid, forged rods and £260 of supertech inconel exhaust valves are only good for 275BHP - I will spread the word and save hundreds of people thousands of £'s upgrading

There is no k04 which gives you 400bhp on a non tfsi engine
Simply because of a small turbine a/r = high backpressure.  No matter which wheels are used,  a/r always stays the same
Its a 9 deg timing for now, how do you think what happens @1.6 bar for example? 4 deg? Useless with stock CR and non racing fuel
You can try to raise the pressure after 4k (pretty safe for rods)  and watch for airmass / iat / egts etc changes

Your wg is overtightened,  another simply rule here - take a spring which gives you ~90% wgdc @redline with specified pressure. In that case you have a 90% range to operate (not 29% you have)

Its a weird thing also to tune timing with an kfzwop2
Use kfzw for that
Kfzw2/kfzwop2 used when nws active (1800-3000rpm on your engine)

Thanks for your advice.

with dyno's over 400BHP on his AUM 1.8T Lupo

most AET380 fitments on TTForum / ASN are around 360-380


also I think TTE make some turbo's closing in on these figures too, but they have a K04-64 frame instead of a K04-23 so unfriendly to a quattro 8N / 8L especially in the UK

thanks for the extra details,  I actually dropped all those timing maps (in that area) - but returned to stock as I think it was a fluke not to get timing retard in my test run, as I had also reduced the load in that map too.


I need to do some more reading   Like I said I am happy with the fuelling it is following my LAMFA Map and I have a safe BTS map to fall back on.  Other than that it is just inching forwards, then backing off again - but as advised now quite a bit releasing some actuator pre-load will hopefully give some more control and a recognisable PID - as I did change the axis to 0,4,8,12,20,30,40,50,90 to suit my LDRAPP Tool runs





I will look to reduce the actuator pre-load to give a wider range in control
