Ok, Turkey Day has passed... What's the dealie?! Interested to hear more about your progress!
Very nice! High five!...and I installed them today!

I’m going to load the preliminary tune using the Flash and work on the idle.
Thanks. Oh, and Chris (ryu) deserves a special thanks for helping develop the pipes I'm using... I heard that GCT charges more than a grand for those pipes now. Sad.Very nice! High five!
What size injectors are you using and what changes on ecu flash did you make to compensate for the larger injectors?Thanks. Oh, and Chris (ryu) deserves a special thanks for helping develop the pipes I'm using... I heard that GCT charges more than a grand for those pipes now. Sad.
Anyhow, with Pocket Logger in hand, I started her up. As expected, with a reset ECU and a new Flash tune loaded, the car hunted (500-1000 rpm) a bit during idle. When it settles down, AFR were between 14.7 and 15.0 @ 710 rpm. The longer the car was on, the better it idled. If I need to adjust the ISCV steps, I will... but I want to see if the ECU can adjust for now.
The first drive was fine. LTFT go from 0 to 3+. After deceleration down to idle, it hunts a bit, but is slowly improving. I stayed pretty much in no-boost conditions. With my BOV set to soft, I did hit it a couple of time between 2500-3500 and boost was 1.8 psi. I felt a slight difference from stock, but I did not stay in boost long enough to really feel the effect. AFRs seem normal at that rpm level. Even though the BOV is recirculating, I get a nice fsssssshooo, when it opens.
Right now, the car drives like stock and I couldn't happier. A bit of work to do on the tune, and I'll have some logging sessions with the ZT-2, EvoScan, ECUEdit and whatever other device I can throw at it. No codes or pending codes at this point. :twothumb:
Thanks. The weather here is rain and I still have the splash guard off. I plan on securing the MAF a bit more with some bailing wire... I want to do some basic non-boosted driving, get the fuel trims right and see how the ECU reacts with more time.Seems to me that the periodic rpm drop to 500rpm is due to the ecu trying to recorrect everything. If you guys can prevent that, then you are made in the shade :bigthumb:.
On a second note, im pretty sure Kris and Matt dont have any rpm drop any time, and cold starts are a snap. (Both have haltechs).
Im insterested to see how things turn out for ya.
We see how it goes. I've already decided to have new seals put on by Vortech. When I drove around with out the piping, I still saw and felt a tiny bit of oil on the outlet. I'm keeping a close eye on it, and after I make some head way on the tune, I'll pull it to send for refurbishing.Things all sound really good for you man - glad to hear it. Your setup is basically identical to the SDS setup I had planned a while back if I went that route - if all goes well for you it might (once again, sigh) give me something else to think about (currently I'm stuck in the turbo or all out N/A debate with myself). Keep us updated on those things like the oil leak and any other mechanical problems that might crop up, and good luck!
Yeah, I'm running 310s with the stock pump and FPR. While the car was N.A., I hadn't seen different LTFT beyond 0.1%. The rear LTFT would mirror the front LTFT. I may reset the ECU and see how they settle again. It's a good point about the cam offset, but you should see the same thing N.A. I gut tells me that the FPR could be doing something weird when I into low vac and boost situations.Could your offset fuel trims maybe having something to do w/ the cams?
You are running the bigger injectors on the stock pump?
Exactly. The thing is Greg, even though I know how you feel about Extreme, they are just down the street from me. A convenience that is hard to ignore.01SpyderGT said:Not trying to hijack his post but, he was working with them to try and get pipes made for me and anyone else who may want them in the future.
Yup, it may be hard to see in the picture, but I used a 1" molded radiator hose from the auto parts store. It goes directly into the large coupler that fits onto the inlet of the SDS.Are you recirculating the BOV?
Definitely! The goal was to have the entire project done, then post the tuning results, and other helpful hints to others going down the SDS road. I wanted to avoid the "...well, today I put on my air filter..." type of step-by-step thread. As you can see, I got to a certain point, excitement took over, and I had to post my progress! :bigthumb:Rep, once you get everything in tip top running shape, get us some videos man. I am excited to see how your stock motor handles the boost. Keep us posted!
