I'm looking forward to getting the armrest in (it's been a long time coming) and also hooking up and tuning the engine. Pending some further tune developments I may try some flex fuel/e85. I'm still waiting for the Eibach R2s, but once they're out I'm ordering them. I want to get those wheels soon as well.

OMAHHHGEERD THAT'S SEXY!

How are those DC tips holding up to the road salt?

No issues what so ever (although it hasn't been long). I really do like the look over the OEM tips.

Me too, and Perrin's 160 dollar tips, while stainless and probably better... they're also 160, ya know. That's kind of silly.

Yeah and you can always pick up some rust-resistant coating or paint right over them.

Update

I receive my unichip today and instead of overloading a single post I wanted to provide a couple quick updates.

- I should receive my armrest any day now. (sutty's)

- Ordered a set of ESM004s (quality BBS LM replicas) in 18x8F and 18x9R. The front has a 1.5" lip and the rear has a 3" stepped lip. I'm excited to get these but they will likely sit in my garage for a little while. I want to get the Eibach R2s in and on the car and run a little more rubber off. I'm hoping to get a set of discounted Direzza 1s with the new 2s coming out.

- Unichip is coming today. The FedEx guy wouldn't leave it despite my polite note so I'm picking up from a FedEx/Kinkos after work. I have the software and tunes loaded on my laptop. I plan to give it a try and see how it runs. They are working on a tune with a AEM intake but it's not out yet. I plan to swap the red conduit wrapping around the wiring for black to make it look more subtle. Stay tuned, I will provide a thorough review and impressions.


I have been working hard to log data and plot some baseline (w/ AEM intake) dynos using the virtual dyno software.

I'm running a generic OBD II Bluetooth reader (post)

I'm logging data via the Torque app for my Droid 4 running the latest Android OS.

The virtual dyno software allows you to utilize smoothing. I'm configured to have a data feed every .1 sec from the Torque app. I plan to experiment with every .2 to see if it helps to naturally smooth (reduce errors).

I have found some consistent conditions to test and have found the results to be pretty accurate. I will upload some comparisons later. My method is attempting to make the same runs in the exact same place/same speed (hit the throttle at the same RPM and mark). Certainly I aim for similar conditions (tire pressure, temperature, wind, etc). I weighed my car in at 2784lbs and added a cushion of 215 lbs for me and the fuel. I weigh about 185 lbs and a gallon of gas weights about 6lbs. I set the drag coefficient to .27 and inputted all the gear ratios. I used the provided calculator to determine the total tire diameter.

Note - Don't get hung up on the absolute number, just make sure you're consistently pulling similar plots and the graphing is consistent with your runs and other dynos that have been posted. I can make my peak power 166whp or 181whp, it's the same curve so I don't care. It's all about consistency and when I install the unichip, it will give me a solid baseline.

My "test track" isn't the best location it's an on ramp to a highway (long straight away) but it's convenient. I might try to find a better stretch to do it as there is a slight decline. During my complete pull from 2K rpms to fuel cut off in 3rd gear my altitude drops by about 7 feet (so there's a very slight decline). Due to the traffic in NoVA I chose to do 3rd gear pulls as you're not too far over the speed limit. I'm guessing 4th gear would provide a more accurate plot though.

Results: (equipped with AEM CAI)


Here is a plot of the A/F ratio during the pull. I had to pull it into excel to plot (need to learn the virtual dyno software better) but it's the same pull/same RPMs just without smoothing. I see that as an advantage as I can compere to the unichip tune. I have logged a ton of other attributes as well to analyze the tune.


I also was able to do a quick 0-60 test near my work on the way back from lunch.
Results:
0-30 MPH - 2.5 sec
0-60 MPH - 6.7 sec
0-80 MPH - 10.7 sec

As most of you know the 0-60 can be pretty deceiving as the shift point is at 59MPH. I went 0 - 59.1MPH in 6.4 sec and it took me .3 sec to shift from 2nd to 3rd gear. The actual speed at 6.7 sec was 61.5 MPH. So if you raised the rev limited a tad, I would have hit 60 in 6.4 sec. The shift from 1st to 2nd took me .2 sec.

The unichip arrived:


Well packaged and great instructions. They didn't leave anything out, this is a complete end to end kit.


As I mentioned, I don't like the red conduit. My neighbor happens to be a former electrical technician and gave me a roll of 3M Scotch 33+ vinyl tape. He said it's the best for keeping hot and cold out.


Half-way (for comparison purposes):


Finished product:


I have a lunch meeting but after that I plan to install. I have the maps loaded on the unichip. The software is a little basic/dated but it's easy to use. I'm going to try and run the Airaid CAI map. I have an AEM unit so I plan to disconnect the MAF unit supplied with the AEM and use the unichip plug. I'll report back on the install and impressions.

Those wheels should be amazing, great job setting up the virtual dyno and baseline, great job wrapping the Unichip harness in black! It will be much less noticeable than the red.

In for the results/review!

Update

So I installed the Unichip. The install took about 45 minutes. My recommendation is to slow it down and take your time. It can be a pain to get to two of the sensors but you want to make sure you do things right the first time. I ran into two snags (installation error) but Jack from Unichip answered the phone and walked me through what he thought the issue was. He was spot on. I would have walked through the steps myself but I figured they'd know exactly what the issue was.

Note: They don't have a tune available yet for the AEM intake system. I loaded the AiRaid and Injen tune. They feel a little fuel heavy and from scanning the A/F through the power band it seems to be a little rich.

Results: No CEL! It's raining so I couldn't get too crazy with the car but did some pulls and logged some data. The throttle response is improved and the car feels to have more grunt down low. The powerband is smoother but I think I will benefit when the AEM tune is released to get some omptimal performance up top. The car feels quicker but I need more time to analyze the two tunes. Interestingly the log shows a lot of extra rows of data. Where I use to have 1 entry per RPM, I have 3-4. I'm not sure why but I will continue to see what's going on. Because of that, I don't trust the virtual dyno numbers and might need to "clean" the data. It looks like the A/F is running rich.

Very happy I wrapped the conduit in black, so much more subtle:

[QUOTE=swift996;699279]Update -

I finally went down to home depot and grabbed a 3/4" poly plug and inserted it into the firewall where the sound tube went. It allowed me to fully remove the noise generator. S/O to a forum member for sharing their story about it.
/QUOTE]

Could you explain this a bit more or link to the Forum article, I'm interested to know more as Ive been working on getting the road noise down a bit on my car. Also, I like what you've done, great stuff!

It's real simple. Just get a plastic plug and insert it into the firewall hole. Below is the thread (sorry I get lazy on linking sometimes)

Ordered these bad boys!



My wheels should be here on Tuesday but I wan't to get the coilovers in and installed first before I order some tires.

Update

I received my custom armrest from Sutty today. It took about two weeks to get from Australia to the east coast. The pics don't do this justice. The materials and fit and finish are top notch. It feels and looks OEM. I haven't had an opportunity to drive with it yet but it seems like it will be a nice addition.
