Looks amazing! Damn it's clean! Impressive!

It's all coming together - if it was me (now, granted, I'm a nervous nancy) I would wait to get the stuff back from Wiring Specialties ... you've come this far and it'd be a shame if something was overlooked and it cost you the build...

Have you contacted Link's customer service about the issues with the O2 Sensor reading? I would get a quick 1min data log and send it to them. They probably can figure it out pretty quick.

Can you drop another sensor into the AEM to ensure it's not the sensor? You've got a AEM UEGO reading the sensor then sending a 0-5v signal to the Link? Can you put a volt meter on the wire to see what voltage is coming out? Sounds like you've double check the wiring is ok? can you confirm it's being sent to the correct ECU pin?

I would jump into your calibration table and make sure it 'looks' right too - if you want to send me your base map I'll do a sniff test on it ... I'm fighting some cold start issues and it turns out most my pre-crank / crank enrichment / warm-up tables are turned off!! I can only blame myself.

Thanks man I am trying.

I figured out the issue, it's calibration, I am getting the proper voltage on the wire from the gauge to the computer it's reading about 3v at 16AFR on the gauge.

Ah i feel for you, i have been in the situation before cold start is a ***** :P

I am getting the car tuned this Sunday or the Following Sunday, wiring specialties box just shipped out today it is on it's way back.

Sorry for the late response.

CORRECTION TODAY at 4 PM, didn't realize it's 12:30 AM pst!!!!

WISH ME LUCK BOY'S

Also installed the louvers just finished working on the car didn't have time to install the nismo suspension, I had to install new plugs and gap them to .026, change oil, put 94 octane in the car, and a bunch of other little things to get ready for tomorrow!!!!

Don't mind the catch can lines they are temporary.

Final numbers dyno is reading 16-18% lower and peak hp is around 450whp on pump gas with stock cams, ran out of octane e85 will make a huge difference, that will be coming later.

Right on - happy the car rolled on to and off of the dyno under it's own power!

What boost level got you to 450hp?

What do you think the engine will make on E85?

How was the Link to tune on?

18 psi

600 on e85 we ran out of octane

The tuner tunes links all the time he's very familiar with it, he almost only uses them specifically.

The car was tuned by a private tuner Bill from indy speed. He is a well known tuner that is no longer open to the public

Right on - yea, that's the beauty of E85!
Happy to hear the good reviews of Link

What's your timeline for the E85 tune?

Yup the link is good

Couple months at least, i wanna enjoy the car at moderate power and learn how to drive it with the different motor and all, then when i feel it's getting slow i will do, Cams, twin pumps bigger injectors and get an e85 tune.

Also the car is pretty nasty off the line with 10-1 compression and a small frame turbo. the e85 will be for track use only, 450hp on the street is enough to **** people off and get a ticket already.

Also I installed the s-tune suspension car is so much more firm and wayyy less wheel hop, plus better handling, all around good upgrade over stock. Now I need a Diff bushing/brace and some traction bars

Unfortunately the car has a pretty bad oil leak at the moment, I believe it is coming from the back of the valve covers, I will be putting some dye in it tomorrow.

Looking at some, and some diff bushings with aluminum sub frame sleeves

Z1 Motorsports 350Z / G35 Adjustable Rear Traction Arms

I was also looking at SPL but it's so expensive, maybe for good reason. :P

I have voodoo13 camber arms and they are pretty nice. From what i have seen from local guys the z1's are pretty good as well, especially for the money. If you can find out wether z1 uses forged or cast ends to determine which ones to go with. Z1's do look cast but don't know this for certain. One reason i went with voodoo13, they use QA1 rod ends. If i had a way to source the additional money i would def go with the spl titaniums. Superior quality and very easy adjustments that your alignment shop will appreciate and save you money when having adjustments made.

If it was me, Id buy the SPL. They are substantially beefier/bulkier, feel heftier (as compared to what's in Z1's picture). I have stillen camber & toe adjusters on the rear and I'm going to switch them to SPL as funds permit.

And nothing against Z1 - I think they make fine stuff.

Downside, yea, they are twice as much ...
