CW stage II question

[jcdeng]

Hi, for those of you who went the CW pro stage II route, what pulley did you pair it with? thanks.

[doug97gxe]

i'm pretty sure mike is the only person who did this

[jcdeng]

oh so pretty much just get the stage I and be done with?

[bhvrdr]

I used the AWE pulley. J. S4 posted he used the CTS pulley I believe. Not sure about the others. The pulley sizes for the major pulleys out there are pretty close to each other and should not make a huge difference. I'd only go stage II CW if you have 93 octane.

Thanks Mike. Yes, in NY there are 93 available in every gas station and I only use 93 on all my cars.

Yes, I used the CTS pulley. Shouldn't be a noticeable difference between pulleys. In good DA both Mike and I were bypassing boost (up to 10% for me) so one could argue the stage 2 map isn't quite aggressive enough to take full advantage of any pulley.

I'm installing the cts pulley tonight , but I still need to send out my cw box out to them so it can be updated for the pulley itself . I will report back with feedback on how it went . It's gonna suck not going WOT till the box is back in my hands .

Ny 93 is like 91.. It sucks.

[jcdeng]

Ny 93 is like 91.. It sucks.

Really? this is the first time I hear this, even my tuner in NJ for my jdm cars never mention something like this to me. care to elaborate?

[AmrS4]

Winter 93 sucks ,other then that how does living in NJ make a difference in octane ? Lol .

[DGVR6]

Nope 93 up here sucks in general.. I get massive timing pull with 93 . I was chasing it for a long time, changed spark plugs, coil packs, fuel filter. I'll add a little e85 and itll start pulling roughly 0.25-2 degrees up top, sometimes none.
There's one shell gas station that I use out here on Jericho tpke and it seems to be the best one I've found .

Any reason as to why running stage 2 cw on 91 gas wouldn't be worth it? I live in los angeles and ive been seriously considering the stage 2 & pulley

[604bking]

Isn't octane rating regulated by the FTC in the US? How can one state's 93 octane be different from another state?

I wouldnt run it on the CA 91 octane because there have been forum members posting 12.6 degrees of knock retard and a even 14 degrees of knock retard on the winter blend stuff. There was a member who switched to the summer and the knock went down to 4 or 5 degrees IIRC. It can make a huge difference. That CA winter stuff is unreal. If the stock timing profile is pulling back that much timing then adding boost is just going to make it pull back more and I have to think eventually it will force the bypass valve opened. For crap octane you need to start with with a less aggressive timing map so you can keep the bypass valve closed. If you logged, you could see if you could run it or not. You could probably even add a splash of e85 and it may work but you really need to log in those situations.

I haven't logged, but I've been running the 5-1 setting and my car seems to be running like a champ. If I get the pulley and upgrade he CW program I could only assume it's going to run faster no? My car is also manual so I'm not worried about potential transmission issues with the DSG.

Its very tough to tell without logging. You'll likely see some torque down low regardless but if your car is knock retarding badly in stock form than your power up top could actually get worse the more boost you try and add. I'm not saying that will happen because I havent logged your car. Its just a possibility when dealing with poor quality fuel. Logging will tell you if you are going to get some gains up top though.

would I be able to run e85 with the chipwerke no problem? I would think an ecu flash would be necessary to run e85 but im not quite sure. I have an e85 station right by my house.

Definitely log your car. Even with good fuel it's probably not wise to run the CW without logging regularly. You're not necessarily going to feel 10-12 degrees of timing pull in the seat of your pants, but that would certainly be an indication that the car is not "running like a champ". If you're already pushing the limits of the car with the box alone, adding a pulley will only exacerbate any problems you don't know that you currently have because you haven't logged. There's a good chance you might be fine too, but why leave it to chance.

[bhvrdr]

There are some folks who have run up to 30% e85 and it helped out the timing a lot but, again, i'm very conservative and I would log before doing just to make sure your fuel trims are keeping up ok. I'm gong to sound like a broken record and recommend logging until enough people have reported safe results :)

I came from a heavily modified 335i (n54) when I used to log my car I'd look for individual timing between all 6 cylinders . What are yo guys looking out for in this platform . I just installed a cts pulley last night and I have a CW tune .

If you wanted to run just a decent safety log on the car i'd do the following keeping in mind the vag com is limited to 10 channels:

1. Throttle position
2. Engine Speed
3. Actual Lambda
4. Specified Lambda
5. and 6. Knock Retard Cyl 2 and Cyl 6
7. Bypass Valve
8. Actual Timing
9. Request Boost
10. Actual Boost

You can always substitute request and actual boost for more cylinders of knock retard if you want since monitoring the bypass valve will tell you if you are making max boost anyways.

Ah alright , what's considered a safe zone for timing degree on these motors ? For instance I was running like 11/12 degrees of timing on the Bmw but that was with e85/meth for safety .

[bhvrdr]

The actual timing is going to vary based on conditions, fuel quality, etc (varies wildly from 10 degrees on crap 91 to 20 degrees on good 93). I'd pay more attention to the individual cylinder knock retard numbers as that depends solely on info from the knock sensor.
