The ultimate is a better choice by far, but it is not easier and it doesn't really do any "self-learning".

Ok, I was going off of what I remembered from the very long thread. It was regarding the EMU filling in some values in the map for you based on the WB02 feedback when connected directly to the EMU.

If I use the Boomslang harness, am I pnp?

By the way...what the heck are the jumper settings? Could you *please please* provide them to me? I wish GReddy was more responsive. I've talked to them and they are not friendly or easy to talk to.

Well...back to typing up my masters thesis...what a dark cloud hanging over my head. :Eyecrazy:

Some good news!!
 
I got my car back today. They installed a hose barb at the turbo compressor outlet and routed the line for the wastegate to it. I have a boost Profec B Spec II boost controller connected as well. This has solved pretty much every problem I have been experiencing. No more stumbling and rough idle. At first the power was much tamer than before, but this was because I had to tweak the boost controller. I'm still tweaking it, but the results thus far are extremely good. As Jeff mentioned in his definitive fix #2, the boost was lower by a couple of lbs, and so the boost can be increased with the boost controller to compensate. The exhaust is not nearly as rich now as well.

The car is so much smoother now I cannot believe it. Drivability is 100% better. The only issue seems to be the BOV is "chattering" worse than before.

Any recommendations where to connect this? Should it stay connected to the intake manifold? That is where it was at, but it was rerouted with the wastegate/boost controller vacuum lines. I saw the post by Ryan that the GReddy BOV sucks. That's a shame because the price sucked too. Perhaps I should get a different one like he said, such as the HKS.

I also got the oil restrictor installed....so hopefully I won't be seeing any white clouds behind the car any time soon.

I believe that I should either try to install my EMU, or get rid of it, and just buy the kit from Mohd. Again.

i have the greddy type s bov, works fine for me. if you have the type rs and want to sell it, let me know. I might be interested (just so I can get a different bov sound)

if you get a hks, you'll need to reweld your charge tube.... since they aren't interchangable.

my bov is connected to the intake manifold nipple (driver side, underneath). But I think you can connect it anywhere since it's not a vital component for fuel management or anything. the intake manifold is nearby so most people use that location.

It is a type RS. I plan to reconnect it to the intake. If you are having good luck connecting it on the driver's side underneath, then I'll give that a try. I just know that it is not working properly now that it is connected to the output of the compressor where I connected the wastegate/boost controller vacuum line. I drove the car about 60 miles this evening, and I cannot believe the difference. It's amazing what simply moving that line did. I tweaked the boost controller, and now I'm good to go. It's a happy day for me! :yesnod:
