Overshoot is from dc needs a littlle bit of massaging. This is not a 100% ready file. I have pressure tested it, didn't find any leaks. Have noticed the throttle intervention bu no idea whats causing it.. The logs work for me, so not sure what you mean? But i will do some reading

You just need to log more variables, but not too many.
Look at the new thread about stage 1 tuning.
Guys have posted list on log variables.

Two things out of this log

- I don't want to sound like a broken record but you are sure your base boost pressure is correct? If it's really 1bar @higher RPMs your WGDC is way too high. That's why you have big boost overshoot.

- Why is your desired lambda @ 0,8 at low loads?

Okay, thanks. I will take a look at that.

I have about 0,9bar With n75 unplugged. Tried to modify the base map as you showed me earlier because I have a part-throttle hesitation and the pressure builds up way to fast in part-throttle.

Will go through dc settings, they are a bit high...

About low lambda at low load is something changed in the file that i can't find. It drops the afr to mid 12's and mileage is really bad. I can see in 2d and map-preview that there are made changes that i dont know what is..

Guess I will take a fresh Stock file tonight and og from there

The 0.8 lambda was lamfa axis issue. It runs much better now, and learned a thing or two on the way  Smiley

Haven't been playing so much with this car lately, but made some tweaks today and it's much better now  Smiley

No throttle cut like i had before because of a bit of overshoot. Pulls much harder now, and it's smooth in part throlle after tweaking KFMIOP and KFMIRL

I see 3kw in ign retard, this is kinda normal right?

Happy days, next step is ev14's, any suggestions on that?

You should probably use 5120 ... do you have a boost gauge and a wideband?

Guess 5120 is the way to go later on. yes, gauge and wideband is installed. Pretty sure the rs4 injectors is at their limit now..

Don't remember exactly what it said. Think it was around 520hp/680nm

I don't really believe in that number because it differs very much in conditions and so on..

Had to cancel the tuning yesterday, because of a brand New MAF decided to die.

New 1000cc injectors and MAF are on it's way now

That would be Bhp not whp?
Power does varie depending on amp pressure, iats.. So is it for everyone Smiley
You get a nice middle estimate.

Yes, that is bhp est. Would like to see someone make that in whp on standard injectors Smiley You are right that you can use it for the same car on the same road for comparison.. Im pretty happy that it goes this well at all as it is now. Try to dial in big injectors this weekend, and hoping to get the fueltrims right so i can start make some power Smiley

bhp != crank hp either.

bhp are completely different units than HP (CHP or WHP)

Oh, okay.. Thanks. Did you manually dial them in? How did you come up With the values like KRKTE an so on? I think i'm in need for a good starting point Smiley

Sorry, crank HP, meant that.
