Dual pulley stacked with stage two Chipwerke, what setting are you running?

[elijahallen]

I just added the JHM 179mm crank pulley and am curious what setting people are finding best when staking a chipwerke box on this setup and custom tune. I have it on 4-1 now and have tried 3-1 as well as 2-1 but they all seem pretty similar.

The least aggressive setting that allows a sufficient closing of the bypass would be the "safest" setting. Have you logged without the CW?

Mines set on 3-1 mainly to preserve shift smoothness during part-throttle situations, but I have about a 8-9% by-pass (4-5% with the 179mm though) in the mid-range at WOT. On 4-1, its pretty much eliminated, but it induces some rough part throttle upshift behavior at certain throttle settings.

Do you need a CW with a custom tune? Thought that was just for canned stage 2 tunes

Yes you'll have to log like Loe said to see what works best on your car/conditions. With the JHM pulley I'd set the CW to 3-1 on my v3.1 APR tune (running the 100 octane map) and found that to work best for me. When IAT's' were good I wouldn't bypass at all from a dig through 3rd and what I could manage in 4th before running out of space..

@Loe got me back on the road with his downpipes so the testing resumes. Ive started with 3-1 on the KI 194mm pulley and so far it's a monster. Darn heat wave just hit here so the conditions suck... Can't wait for it to cool down again!

Does it make any sense that I see more boost on 2-1 then I do on 4-1?

Yes, the 2-1 is less aggressive in how it tricks the "actual" ecu value

Glad you are making your rounds on the 194! So far everyone whos had this pulley says its a monster! I love love love it!

How long have you run the 194 Loe? Any DSG slippage?

About a month now. No DSG slippage, interesting thing about DSG tunes though, a few of us have spoken behind the scenes and compared clutch pack clamping pressures and you'd be surprised how well the OEM tcu tune stacks up....enough to make you wonder where your $400-$800 actually goes towards.

Having major 194 envy

I wonder how much torque this DSG can really handle

I guess I was confused, I thought the CW was supposed to raise boost the higher you set the ratio? I need to find a custom tuner. The guy I used on my B5's doesn't tune these cars so I am at a lose. It just seems like this motor has so much potential but needs more boost to obtain it and 14psi just isn't cutting it. I have a manual trans so not worried about that part.

It raises or maintains the boost by tricking the ECU into thinking that the boost is lower than what it actually is to keep the bypass valve shut. If you log via VCDS, or use any form of boost gauge that is read off of the OBD-II port (versus an actual boost tap), then the reading will be less despite that the boost will be maintained or higher.

Lets say your Malone tune is made for 16.5psi. With the introduction of the 179mm crank pulley (that can potentially make 19-21psi), your ECU will bleed any potential boost above 16.5psi. Now you introduce a new item into the mix: a CW unit. The CW unit sends a signal to the ECU that the boost it's making is 15.5psi, this forces the by-pass valve to close as the ECU is thinking to itself that it's not reaching its target of 16.5psi. The closing of the by-pass valve is what produces maximum boost, so in reality if you are reading the boost via an actual boost tap, you are making about 19-21psi depending on ambient pressures.

If you are stacking on top of a tune, you really should look into purchasing a VCDS logging tool to make sure the car is happy. Depending on how the boost is requested on the Malone tune, you may not even need to stack the CW on a 179mm crank.

When we logged it yesterday with vcds, max boost was 13.8 in 2-1 config. I was expecting much higher and now I am wondering what the tune is and how this car made 415whp before the bigger crank? Its quick but feels like there should be more for the power claimed. Anyone know Malone tuning? I had never heard of them. I have tried to contact them for more info but have not gotten a reply. Thanks for the help Loe, feeling a bit lost on this stacking mods stuff, with the B5's you would blow the car up doing similar and tune was everything so I feel like tune could do so much more on these.

Malone is huge in the TDI world.

By design, your actual boost in VCDS will always read lower with CW than your actual real-world boost.

Ok, last question, where is the best place to tap in to see actual boost that the car is making? Thanks, I'll get this haha

Get the ECS boost tap. It goes right on the SC outlet
