B8 A4 2.0TQ6MT Tuning Stage 1/2 94/91Oct (2011)

Hey guys!

finally got bored enough during this Pandemic and decided to pickup the credits to license my own vehicle and do some tuning :yay:

I have a few logs of the car when it was stock and one from after my tuned file, its currently on 91oct while tuned but I plan to switch to 94 once its empty and see how far i can push the envelope. I must say I'm pretty impressed with the overall HPTuners experience the first flash took about 3mins and 30sec, but every flash after only takes about 20-30sec very surprising for an MED17 controller, still getting a few params added to the logger so I can really push her but they have been very responsive for support on this vehicle.

This is what i have so far, there's a huge difference in WOT power and the regular drive ability hasn't changed at all

if anyone has any questions or query's let me know :)

Heh... I expect your boredom will be our gain! :)

Thanks, hopefully I can learn something by studying what you have done.

Thanks for the reference tunes and layouts! HPTuner just added support for my calibration so now I am able to read the calibration. I have a A4 B8 2.0TFSI Q but with the DSG, it has a unknown stage 1 tune so your stock reference calibration is really nice for comparison! I am fairly new to tuning so bear with me... First thing I noticed was that my wastegating seems to be disabled, is that a correct conclusion?
There are some RPM cutoff for VSS Fault differences but maybe this is related to the different gearboxes, not quite sure what this parameter is controlling though. I haven't looked in to the transient fueling differences too much just yet. There is a axis difference in the indicated torque map which I don't think is a big deal, even though I might benefit from adjusting the indicated torque map since I have deleted the balance shafts and mechanical water pump. The rest of the differences are all in the driver demand torque management. I have to admit that I have not yet understood the meaning of the different variants.
I am extremely annoyed with the lag I experience when coasting towards an intersection and going back on the throttle, it is in the multiple seconds range! On this subject I wonder if the anti-jerk TIP-in hold of 2.5s can have something to do with it?

I need to dial in the controls of my electric water pump before I can do any real logs to understand my calibration better, but hope to have that sorted during next week.

All comments appreciated :D

Welcome :) if you dont mind making your own post id be glad to help you tune your car and would also be interested in seeing some logs of this "tuned file"

Happy tuning!

@TylerDubbs: Thanks! Some help is extremely appreciated. I did actually start my own thread on what to expect before getting the software to work, it is here: https://forum.hptuners.com/showthrea...build-HPtuners

I am still trying to dial in my cooling system which is right now utilizing the can bus on the OBD-II port to read coolant temperature. I want to get rid of that communication before starting to log some pulls with VCM scanner. So it will at least be a day or two more before I have any logs. I see in your logs and others that you are running a bit lower coolant temperatures compared to mine, I wonder if there are different thermostats.

I'll continue in the other thread.

Cheers!!

Thanks for the files!! Perfect timing! Im learning the software now, and working on adding a larger t3/t4 turbo in series with the stock ihi on my a5 2.0t and adding my diy water meth controller!! I've heard some of the parameters on the med 17.1 are a little illusive. Im not quite sure where to start tuning wise as pluming for the secondary turbo is being completed now.
From what you've seen are there any limitations or tips i should be aware of as far as fuel demand and integrating a second boost curve into the mapfrom the compound?

Honestly that sounds like a crazy setup haha, no experience with compounds on ME in general so i guess we will need to see logs and go from there :)

Also I’m not sure if anyone may find this information important but I found out today while messing with waste-gate control that the B8 has a 3bar pressure sensor LOL.... I always thought it was a 2.5bar sensor like most other vag cars

Gee, that's tragic. ;)

Haha man, this opens up huge opportunity for the big turbo side of things :cool: being that the wastegate control is feed forward closed loop control to 29.5psi

What part # is that? where did you find that i have always been under the apparently misinformed impression it was 2.5 also as i posted a few weeks ago in elaws thread and the 4 bar sensor is PN: 0281006059

038906051E

I actually wrote Bosch to get a spec sheet for it to confirm, still waiting to hear back.

But I did also hit 2.8bar absolute pressure which was read by the pressure sensor, also the sensors linearization value in HPTuners software would suggest its a 3bar

hear back from bosch yet?

What version of HPT are you using? Im on 4.6.3 and cannot open it...

***DISREGARD... I needed to update my beta...***

I think most of the newer vehicles use 3 bar MAP sensors. Your slope and offset are similar to mine and I was running the 038906051K. My slope was 65.22 instead of 65.88.

My MAP failed at the track, so I ended up switching to a 3.5 bar AEM sensor (30-2130-50) in the manifold and 4 bar (03k906051) sensor in the throttle inlet. It's a super easy change to swap the wires and then switch the slope and offset in HPT.

For future reference, the values I'm using are:
30-2130-50 - slope 86.18 offset -43.12
03k906051 - slope 87.50 offset 6.25

Note that 03k906051 can't read much vacuum, so you can only use it in the throttle inlet.

*Update* Well just like that..... my clutch is starting to slip from the torque of 4th gear WOT on the highway LOL!

The tune I'm running now is a little bit different than the one posted above as I was experimenting with more fuel and more timing at peak torque :rolleyes:, around .78Lambda and an extra 5* advance in some places

Just ordered a new southbend stage 2 endurance clutch, the ECS Luft-Technik FMIC kit and I'm going to pull the trigger on a hybrid from a good friend of mine and local turbo builder here in Ontario (Turbo Parts Canada).

The turbo should be good for about 400hp on 94oct so it should get pretty rowdy, just need to pull the engine out and slap all the parts on aswell as fix an oil leak from the filter housing/Accessory bracket that i have been neglecting for far too long

In case anyone was wondering E30 blend fuel will absolutely murder a stock clutch hehe

updated versions of my kill mode 94oct and E30 ethanol blend tunes with logs

THESE FILES ARE SPECIFICALLY DESIGNED TO RUN ON MY CAR AND COPY PASTE OF THESE COULD BE VERY DANGEROUS TO A CAR WITH A TIGHTER WASTEGATE!!!!!!

E30 file is hands down the fastest my car has ever been and for a stock turbo car its actually insane.....

You are right 038906051E is a 3 bar sensor, EA888 Gen 1 has the 2.5 bar sensor and EA888 Gen 2 (the ones with AVS) use 3 bar

Hi Tyler, I am having a look at your tune files and they look very good, what would you do different for a similar setup (EA888 Gen 2 K04) with a DSG tranny?

1)Might need to go a little higher on the Driver Demand torque tables just to avoid torque monitoring

2) increase rail pressure until Start of DI angle is around 180-200* advanced (this will be around 160-165Bar range on pump gas

3)Boost duty tuning for a different wastegate setup

Those are about the only thing I can suggest :)

Thanks for the advice, by looking at the files you uploaded (pump vs E30) I see different values on Fuel and Timing as expected, but fueling is almost the same, with E30 there's about 10% more fuel required to keep the same AFR, are you letting your STFT/LTFT to compensate for that?

I used DI injector slope based on LTFT adjustment to dial in the fuelling for E30 :)

Sounds good, simple yet effective for that small of a change. I tried to do the same but I am having some wired issues with my LTFT, they are always 0.0, they seem to be turned off but I do not find where to activate them, or perhaps it is related to the fact that my ECU runs mafless, what do you think?

Hey Tyler looking to talk about tuning for a 2010 Audi A4 2.0t manual with ko4 and other add ons. Just bought the hp tuners kit

Attached is the newest file I've been working on for my B8 with Stock turbo and now custom built HFC instead of catless test pipe. :hi:

A few things I've been working on are getting the injection angle advanced in WOT and maintaining homogenous injection strategy instead of maxing out HPFP pressure to use stratified injection, Cam angle is now drastically advanced at peak torque and slightly retarded from OEM by redline.

At idle the torque reserve is decreased and the cam angle is more retarded to result in a smoother idle that is more torque focused and less emissions focused, this was a drastic improvement over the crappy OEM stumbling idle.

Tyler would know more than me but I dont think it will ever be right running mafless. The maf is needed for load/torque which is how everything works on these ecus.

LAGP has a variant of MED17 that runs in true speed density with a real MAP sensor, he's not running "MAFless" and ive been trying to help him for a while now with some things being a mystery haha

Ah ok yea, its a pretty odd/rare setup that was only on like 1 yr of TT or something. MED17 ecu but almost a gen3 engine setup. Does HPT support that ecu?

The ECU is MED 17.1 and the engine is kind of a transition between Gen 1 and Gen 3 TSI, it is supported by HPT but many PID's are not available.

Hey, not to revive a dead-ish thread but just looking over your two pulls at post 27 and it shows boost pressure doesn't drop off. Is that just the doing of the HFC/test pipe? I daily drive the audi and have plans for my wrx but I would really like to make my audi hold its boost through the rev range and not just drop off at 4500-5000 rpm like it does. I know a k04 would change that but does removing the restriction from the cat allow the stock turbo to keep the boost pressure up? Or am I off base here in assuming the cat even does any of that and its just built into the stock tune? Anything you got would be great

That's a function of the stock turbo. K03s are daily driving turbos (read 3-5k RPMs)... not performance oriented. I went from a Stock Tune/Cat to a Tune w HFC and gained about 30hp and slightly better spool time, but it still fell on it's face past 4500. It was falling to 8-9psi rather than 5psi, but it was still falling! It held it right to that line... then died.

The K04 ( or insert turbo type here) is the only way I found to get it to breath past that. My FT23L (K04 basically) is now doing 26psi for most of the range dropping to low 20s only at the redline. I love it!!!

There are lots of options to get it to flow... but all involve some form of turbo upgrade. Poor little K03 just won't do it!

Good Luck!

Ah alright, I read a quite extensive post on audizine about using the ebay k04 turbo and some people claim really good results, debated using it but its just weird trying to trust the ebay stores, especially when there's reviews that claim oil leaks within a few thousand miles. I'll have to look into the FT23L, is that just an ebay turbo that you found or is it sold by CTS/APR? Thanks for the quick reply, didnt know how active this side of the HPTuners forum was.

FrankenTurbo! http://www.frankenturbo.com/new/F23L.html

I have had mixed results with a eBay sourced turbos. Have one on my scratch built Lotus 7 replica. It's awesome! Due to the complexities in replacing it in my A5, I wouldn't trust it as a daily only due to the effort needed to work on it!

FT offers a 2 year fairly liberal warranty. Doug is a good source to work with (missing parts in my shipment were replaced without issue) and responsive to emails. And the price for the value was great! It's only fractionally more expensive than a stock K03 replacement!

A local Stage 2 S4 owner loves my car and how it delivers it's power... and keeps delivering it till you chicken out! He's mentioned a trade if he could get the SC whine on it! I gotta admit that the V6 growl and SC whine is intoxicating!

Stick with a name and you won't go wrong, but remember, buy once, cry once. Don't cheap out unless you intend to do it more than once!

I'll have to look into that! I did the wastegate repair on my stock turbo last spring and I hated every second of it on the A4, which is also the biggest thing keeping me from just getting a new turbo. I'll get into something one of these days, maybe when the turbo seals decide they're done or the shaft snaps. 163k on the turbo and the motor got a rebuild at some point before I got it but I can't confirm when and whether OEM or Aftermarket parts

Hi guys, I deleted the VVT on my engine and now intake cam is fixed at 14 deg. instead of 28 deg. also changed some of the parameters on the "Variable Camshaft" section, but I keep getting a Crank/Camshaft correlation CEL. Here is the file, if there is something I am missing please advice.
