I gave that a shot and have a question, is load axis of the map the same thing as Alt B?

I also found the reason my lambda was so high. It got colder here and my coolant sensor was dipping below 92C when my motor would rev up. I assume that sends me to open loop. I got the green top sensor and also replaced the thermostat, now it holds 96C solid all the way up. I have a tune that makes much more power and has very little individual cylinder retard. Actually no individual cylinder retard until the last two gears near peak RPM. I'll post all of my stuff and my original bin for comparison when I get a chance. Lambda requested dips to .86 and rises to .96 just before it hits the rev limit. I see my actual lambda rise with the boost and then dip down and try to follow the rest of the way. Is there any way to adjust actual lambda so it can follow requested closer. It seems to swing each way like the loop integral is responding to error way too fast.

From what i understand you must raise a little bit your KRKTE. You have a injector calliration error or you just maximized your injectors flow limit (rather inpropable). What are your fuel trims?

Here are two log screen shots, one is multiple shifts and the other is a second gear pull.

My fuel pressure is 4bar and I reach 86% duty cycle with stock 386cc injectors on the multiple shift log.

The second gear pull shows my fuel requested and actual. The logs are in the zip file.

I've put my focus on A/F and timing following nyet's advice. This is the best progress I've made tuning. Requested A/F is .86, MAF is up ten points. Car is almost one second faster when ran to 100mph.

If there is anything you guys see that may need some changes, I'll do it but I really like this one. Last check, fuel trim is .8 additive and .0 multiplicative. I'm waiting for rediness to finish so I can make some more logs assuming adaptation is complete when rediness is finished.

I'll see what I can do.

YES. Now you are cooking with Pam. Can't wait to see a full log with this fueling/boost/timing.

nice going 

I'm not sure about launch control, I have a six speed and I'm pretty impressed with the clutch feel compared to my drag car.

Here are the logs if anyone is interested in checking them out with ECUxPlot.

I will post my original ECU bin as well as my tune up to this point along with identified maps and all maps but I want to try a few more things first.
 
My tune is factory lambda settings all the time except when the throttle is pressed past 80% so it provides pretty good gas mileage when driven day to day.

Hopefully without starting arguments I have the turbo at max boost over the whole rpm range. I bumped the rev limiter up to 7k rpm and see some go way above this range. I personally don't understand the need as all of my logging shows peak power falls off too early with the stock k04. This does make me question exhaust camshaft retard/advance. 

Most injection shops recommend keeping duty cycle 80% or lower. I think going to a 4bar regulator is a wise decision and my tune creeps over 80% but stays under 90%. The stock pressure regulator will not work with this tune. It is so damn easy to change and a very cheap part. A K&N air filter will help a tiny bit but only if you do not put too much oil on it. The oil can get on the temp sensor and MAF element and also restrict air flow. Stock filter or K&N will show very little if any difference with this tune. All other parts of my car including exhaust are stock 2004 US model Audi TT 225hp 6spd with BEA engine code.

If this tune is to radical, I can think of quite a few ways it can be calmed down. If anyone decides to try it out, please give me feedback and if there are any requests for a different setup, I will be glad to give it a shot and I don't want anything in return.

I will keep testing and I drive my car every day so any issue will surely be noticed. I have had no problems with any of the normal functionality of my car and I regularly check all of the systems rediness with vag-com.

Understood, well ill focus on timing some and then consider it finished up to this point.

Is there a popular turbo direct fit that can hold say 22-24psi to 7500 rpm?
