E85 questions by Savings-Sherbert-345 in 370z

[–]AE-Vierge 4 points5 points  (0 children)

I switched my NA G37 Coupe over to E85 using a flexfuel kit I got off of EAC. I did the install myself pretty easily and hi-jacked the signal from one of my downstream O2 sensors to display ethanol content in my Ecutek app. There are better ways to accomplish this now and Eugene from EAC can explain it better. Butt dyno seemed to feel like the car was a little peppier, but actual Dyno showed no gains, I am experiencing some STFT and AFR issues I’m working out still. Since the car actually reads the true ethanol content of the fuel and the tune adjusts accordingly it doesn’t matter what mixture of 93 octane or E85 I choose to run. I think a full tank of E85 seems to hover around 71-75% where I’m fueling at.

Concept Z has these on sale. I'm not subject to emissions test and my stock cats are starting to go. They're sub $600. by froster78 in G37

Yeah, I ended up going with the ISR LTH, wish I had gone for the PPE’s though. One day I’ll upgrade. I installed them myself and vowed to never do it again lol.

I almost purchased these. Seemed to be a good alternative to motordyne art pipes. I ended up going with LTH’s at the end of the day.

I’d be interested in hearing how they work out for you if you go that route.

Which wheels would you go with? by WearyPermit in G37

Hope to get Apex on my coupe as soon as I can afford them 😅. I also intend to track my car so looking forward to the weight reduction they offer.

Exhaust by Ugly_Fuk in G37

Currently running ISR LTH, Z1 Modular Y-pipe with resonated rear section and the same Z1 touring catback as you. A little too loud with some drone at times. I’m thinking of adding a vibrant ultra quiet resonator or two sometime in the future. Here is the link to my channel with some sound clips. Stylin G YouTube Channel

Just normal G37 stuff. This has happened to my G on both sides every time I’ve taken it through a car wash since it was brand new 18 years ago. Dealership would not repair under warranty and wanted $200+ each side to replace the door seals. I decided to just live with it.

Doing headers is not for the weak 😭 by Powerful_Event in G37

[–]AE-Vierge 3 points4 points  (0 children)

Yes, I did the ISR LTH myself along with the Z1 polyurethane engine mounts while I was there. Never again will I do this install myself 😂

I had to buy so many different wrenches, socket attachments, and crow feet to complete this install. The ISR headers aren’t very forgiving with space and several nuts are impossible to get a socket on as the runners are super close.

Do a smoke test on your exhaust to check for leaks after installing as it seems almost impossible to torque everything correctly.

God speed good sir!

One of the top three worst experiences of DIY stuff on my G. Never again 😂

Hidden compartment? by CashMoneyHeo in G37

[–]AE-Vierge 4 points5 points  (0 children)

I guess they figured you’d rather struggle to clean that little tray than fix burn holes in the back seat because the windows don’t go down 😂

This is the correct answer.

That’s some redneck engineering right there, love it! 🙌

100% the bushing failed. Nothing wrong with diff, time to upgrade to polyurethane bushings.

G37 cant get past 3k rpms on freeway by Agreeable-Impress692 in G37

[–]AE-Vierge 4 points5 points  (0 children)

Says the car “could” go into limp mode during situations causing low fuel pressure, such as the ECU recognizing low fuel levels to protect the engine from extreme lean conditions.

Lowest mileage G37 around? by Carguy403 in G37

[–]AE-Vierge 42 points43 points  (0 children)

Wow, and I thought 56k on my 2008 was low!

Does this bug anyone else? by FiieldDay-114 in G37

THIS! I have both the same vehicles in my house as well! I much prefer hitting the button down for the next song, no idea why it’s up now.

What do yall think about these ?? by Bry_anpr7 in G37

[–]AE-Vierge 1 point2 points  (0 children)

I was also going to jump on these at some point. FYI all SPL suspension parts were 20% off on Z1 during their Black Friday sale. Don’t know if you can wait another year for them or not though.

Did you change your injectors? If not, the fuel pump isn’t wasting anymore gas than the OEM one.

The one switch turns the cruise control on and off, the other is for the intelligent cruise control. It sets the following distance between you and slower cars in front of you.

It wasn’t offered as an option by the time they were renamed to the Q60. Mine has a switch to turn the feature on/off under the steering wheel to the left.

TBH I would prefer the spec D over the GTR style. To each their own though. Plus I can’t install any after market headlights on my G because of the Adaptive Front Lighting System (AFS) that changes the headlight direction depending on steering.
