Frankenturbo F23 + Maestro Active VVT = ????

[spartiati]

So recently I received a file from Chris Tapp that activated the VVT. I immediately felt the difference. Car drove like a damn stock k03s around town and pulled like a freight train.

Mod list:
Awp block with rods
Aeb head with auto tech intake cam
3" turboback with no cat
2.5" IC pipes with dual pass same side in and out inter cooler
Snow performance stage 2 100cc nozzle post Turbo, 225cc nozzle post IC and 100cc nozzle post TB
Stock ported TT exhaust manifold with Frankenturbo F23
Eurodyne Maestro with 630cc injectors
my own big bore Turbo inlet with 6" velocity stack filter
Dual stage mbc 14psi/23psi
Custom large port intake manifold with 67mm vr6 throttle body


Timing was always an issue but I had my file pretty solid. Chris really helped me out.

I'll keep the talking short. I'll let the Dyno do the talking. Remember this is no Hardware change at all. This is with Active Variable Valve timing activated on a new file I received and the timing through the roof thanks to my water meth and efficient intake setup. 28-30* at redline.

Uncorrected it was 349.27whp and 345.42 ft-lbs of torque

Corrected STD was 335.96 whp and 332 ft-lbs of torque

Run 5 is best of today and run 4 is best of last dyno session when I tuned my larger throttle body.




As always Ed, Fabian and Tony from FFE make dynoing a great time. Thanks guys!
Chris You really came through. Couldn't have done this without you.
Doug Your turbo couldn't have been a better fit for what I wanted to do.

If anyone is on the wall about what tuning software to run, go for Eurodyne Maestro. You can do great things with it if you do some reading and have time to tweak!

Here are dyno plots based on rpms.

Wow, holy ****.

[mk4boost]

[AmIdYfReAk]

Not bad at all!

Did you change the VVT at all? or is that "as per Tapp" settings?

[spartiati]

Yessir that is as per Mr Chris Tapp settings.

[hatetolovemydub]

GOT DAM!

[Big_Tom]

[Budsdubbin]

So what were your timing issues corrolated to? Optimal torque maps?

Also what boost were you running? Very impressive numbers

[JWoody]

'scribe

Way to go fellas...

[spartiati]

Exactly torque maps. The base 630 was originally tuned on a 3071r. Obviously this spools much sooner so the car would freak with all the boost and load down low that my timing would be 8-10 degrees of advance at initial spoolup. Now its 18+.

This and all my dyno runs are on 23-24ish psi. Needle sits right in between. I haven't touched the MBC in a while so the boost has been set the same way across all my dyno's I've posted in the past few months

[rodgertherabit]

who needs a GT28 with #s like that!?!?

[Blind VW Drifter]

Wow. Great numbers. Now im 2nd guessing a 50 trim....

[Cryser]

great numbers. did you get your TB issue's figured out with the tb airflow map?

I was thinking about it and really the only way I could come up with to tweak that map would be slap a MAF on datalogg around town then keep tweaking the map till the load values matched. Then work with the opt torque maps till everything was good.

But you can really tell the difference once your torque maps in the high end are dialed in and you get 20* of timing instead of 12 =P

Cryser I tried using the MAF but honestly its damn near impossible to use IMO. Full throttle its useless and part throttle the figures it gives you to tune just suck. Nowhere near the actual values. Best is to always use percentage increases or to decrease airflow. Most of the changes will be in the 0-30% throttle range.

Make a global change after you change your throttle body, flash it and let it idle. Keep making corrections to idle first since that's the easiest to set. Then find a nice stretch of road and try holding the throttle at each designated pedal position % cell and tune from there. A positive value means the car is anticipating more air then its getting so the end outcome is it having to pull fuel. Go into the corresponding cells and adjust accordingly in Alpha n and TB angle vs airflow and repeat until your dialed in. That's the best way I've gotten it to work.

In regards to my overall timing I was getting about 22.5-24* prior to this dyno. Now its an ungodly 28-30*. This is with pump gas and water meth (regular -20 blue windshield washer fluid to be exact).

[HighFive_GTI]

Bloody Hell!

Could you give me an idea what the MPH translates into RPM? Looks like it is spooled by 55 mph. What RPM is that? I assume this is a 5spd with a 4th gear dyno pull.

[Budsdubbin]

Wow. Great numbers. Now im 2nd guessing a 50 trim....

Spartiati's giving it all shes got. Upgraded TB and intake mani, intercooler, water/meth, custom maestro file with VVT enabled..... It doesn't have much more to give other than stressing the turbo to 28psi. I'm sure 300+whp @ 3400 is no fun for traction in a FWD car.

[doug@frankenturbo.com]

Here are two graphs taken from the Eurodyne Logger's data:

this

the spool on that graph is rediculous! His car goes so hard You should put a disclaimer in your sig lol

[spartiati]

HAHAHA I like the disclaimer part Big Tom

I am upoading dyno plots of the whp and wtrq by rpm. I used MPH because my last dynos lost the pickup on the rpm signal and dyno was blank.

If I lay into it in 3rd It just rips right through 3rd gear. It's pretty ridiculous! It never did that before this last Dyno tune and Mostly thanks to Chris figuring out my torque and timing issue. Him and I have been going back and forth for alittle bit.

Also this is 4th gear pull on a 6 speed

[s1eepydub]

Is this still on the OEM S3 manifold, or the Frankenturbo Ceramic coated manifold? Either way thats god damn impressive from such a small turbo!

This is a stock s3 manifold I ported. Plans for a high flow is in the future.

[Cryser]

yeah the torque maps play such an important roll, ever since I've been getting mine dialed in my car is a whole different beast. I reset my target filling and redid the opt torque and it brought the tune to life over the one I uploaded earlier.

how are the egt's with the VVT, I though I saw something about them being through the roof, was this fixed in your current tune?

how are the 02 corrections looking for a WOT run now that the torque maps are figured out?

I've found it's best to let the car go between (-1) - 1 for your cruising loads (80% and below for me) and let it be (-2) - (-3) for the loads where I'm in boost.

[Big_Tom]

man you waited a long time to get a high flow manifold. i need to get this VVT update asap. I find it funny mr. tapp was helpful to you. he wouldnt lift a finger to help me when i emailed him

[spartiati]

The egt "issue" I mentioned wasnt as serious as I originally thought. I was looking at just peak recorded egt. The high egt was just a spike after I lifted off the throttle. Sustained egt was lower around 1680.

Fueling is fine. Minimal corrections under load. I don't know if there is much else this motor will put out. An exhaust manifold is the only thing lacking and I'm working on a high flow solution that i think will give it some breathing room (lower egts and lower the back pressure) to help the car make some more power. That may bring me closer to the 350whp corrected mark maybe more. Only thing left to do after that is e85 but there are no stations close enough to me so that's out or stroke the motor which ..... well we'll see what comes of that lol.

Without further delay here's some action shots. Courtesy of Frankenturbo. Thanks Doug!

[AmIdYfReAk]

Well done!!!

Those are some impressive numbers..... Are you tossing meth at it? Or is this just straight fuel?

Yessir I added my full mod list in the first post

[One-Eight GTI]

Really impressive, I need you to tune my car when I'm done

cant thank him enough for working with mine... the guy knows his shi*

[spartiati]

Thanks buddy. We gotta get you rods as well as some boost and timing then you'll really enjoy that car!

[Budsdubbin]

I'm lost.... I thought the issues were in the torque maps. According to that video Tapp sent you a file to run "It'll run whatever timing you want"?

[sponcar]

wow im surprised, I can't even imagine how killer it would be to have this set up on a mk2..
My dream right there.

Great job!

[spartiati]

He tweaked the torque maps and added a new feature which will be added to user files soon.

[doug@frankenturbo.com]

Here is a comparison of spartiati's latest dyno versus the FrankenTT when it was Eurodyne Stage1 (stock K04-02x turbo). Absolutely no sacrifice in low-end.

[Budsdubbin]

thats a huge power band but the selling point is definitely the fact that it holds 300+whp to redline. Now throw in an intake cam and lets see what will happen.

[NeverGiveUp]

Can you also post a pic of your Intake Cam timing map?
