Hi All,

Just wondering if the R34 Neo RB25DET fuel consumption is similiar to that of the R33 RB25DET? Better or Worse? just wondering if the VVT side of things made any difference? My r33 gtst was getting about 380-400kms tank (no thrashing mainly highway driving).

thanks.

I get similar economy from my r34 gtt, about 400k to a tank. 400k divided by 50 liters = 12.5 liters per hundred ks. thats freeway and city driving. A bit of boost every now and then, if i nursed to over a whole tank i think id get 450ish.

I have a pretty heavy right foot & I'll still get about 320-350k's before the light comes on

light bolt on mods at the moment, pod, fmic, full exhaust etc.

Once I get my Power FC installed & tuned I should see improvement in the fuel economy with a good tune

Edited by Yo-Yo

my light usually comes on around 10 or 15 litre left in tank

and R34 tank is 60litre

50 litre is may be after light comes on

im doing around 13 or 14litre per 100km

before clean the injector i had 16 or 17 litre per 100km

been improved after injectors

and i bought SAFC and waiting to be install and tune

100% city driving no highway.. may be around 5km hightway from artarmon to city (gorehill freeway)

im happy now but i was expect 11 or 12litre per 100

i hope i achive that rate after SAFC!

recently ive got 370 untill lights come up

im not sure it has really 15 litre left after lights up but if it does real.. i might go around 400 to 450litre per tank.

i usally fill the fuel straight away after lights up. thats about 50litre. so it goes around 360 to 370 per 50litre... so it could be 13 to 14 litre per 100km..

its normal right?

does boost controller makes your car richer? im going to fit boost controller and SAFC and tune them on dyno.. the BC is manual one that forum had big thread about it. turbo tech one lol

anyway would it get richer or if i tune on dyno would i get leaner?

cheers

I've got a stock GTT Sedan apart from coilovers and i drive from epping to erina (just past gosford, central coast nsw) 5 days a week and do a little city driving on the other days - do cruises often thru what i call boosty roads and occassionally within legal constraints give the turbo a good wackin and i manage to get 10l/100km. Around 500km b4 the gauge reaches 1/4 of a tank and then i fill up with about 48-53 litres.

I'm getting 11-12L/100K's out of mine. (ive only filled up 3 times though so we'll see how consistent that is in a month or so) Mostly highway driving but regularly on boost otherwise.

R34 tank is 66L just for the record..

I get about 300-350 a tank.. I worked out if you refill her before half tank u get more bang for your buck .. launching it or not.. ended up with about 75-100km more than running a full tank down.

Used to get about 400-450km per 50L-55L. I found the light in mine was really cautious, ie when it came on I could still drive at least another 50km. That was with 200rwkw and tuned PFC, mix of street and highway driving.

    • The car/ECU will have all the sensor that it needs and expect to have. I think i do not have to explain to you how the Link is way better specialy if you have swapped engine   I just do not want to deal with any "problems" cuz i have only Nistune which i learned is not that great and in my case cant even deal with that speed problem (Link can) And of course it will be way more easier to tune and diagnose and safe. And for the ECU/speed problem...i dont know.
    • Per Mark Roberts of Sonictune: Mark Robert Author At this time, no. No ETA either 2016-17 models. You will be able to purchase and install a 2018.5+ TCU though   TCU purchasing and pricing info! As we near the release of TCU tuning, I am going to answer some questions I get asked often.   What do I need for TCU tuning? At this time, you will need a 2018.5+ TCU to be able to tune. If you have a 2016-to early 2018, you will need to replace your TCU with the newer version. One good way to know if your TCU is good is if you have auto upshift in manual mode in 1st gear around 6500 rpms. If your manual 1st gear goes to 7k rpm and will hit the rev limiter unless you shift, you have the older TCU.   Why do I need to buy another ecu license/phone flash if I already have it on my ECU tune? The TCU is its own computer module. It is completely separate from the ECU. Because of this, you will be required to purchase a TCU license and, if your tuner has it, the phone flash license required to tune it via phone/bluetooth.   Do I need TCU tuning? TCU tuning is NOT required. However, the faster your setup, the more it will assist in track and dragy time consistency.   If I’m ECU tuned by (tuner A) can I get my TCU tuned by (Tuner ? Yes, since it’s a different module and a completely separate flash, you can have two different tuners. However, it is highly recommend that you have both tuned by the same tuner. For me, my TCU tuning will directly complement my ECU tuning style and features and running my ECU and another TCU or vice versa MIGHT cause some issues. At this time and for the foreseeable future, I will only be tuning my current ECU tuned customers TCUs.     I have a SYVECS AWD controller. Do I still need it? Yes! The AWD controllers main job is to control your AWD system. However, with TCU tuning, you will no longer need the auto-shift function as that will be done through the TCU. The AWD controller will still be very beneficial for racers looking to maximize traction on the launch.     Shift schedule changes: holding gears longer at lower pedal input as well as max shift rpm changes. Please note, the new ECU race rom coming out will address 90% of the shitty drivability issues these cars have through custom maps from myself and Racebox—as well as others I am sure.   Increase shift speeds: as seen in the videos I’ve been posting, the TCU shifts much faster once tuned.   Increased shift pressures: as also seen in the videos, much firmer full throttle shifts.

    • The fancy pants red shock tower brace is finally incoming from MX5 Mania, getting it shipped from 'Merica has been a long and problematic process, and GWR, the 'Merican supplier will not ship directly to consumers outside of the US, Mania basically had to order a heap of them, the colour choice was silver, or red, and we all know anything red adds 5 killerwasps of dynotorques..... Whilst it does fit over a 2.5, and I've seen a few photos and videos of it being installed and fitting, google also says it might get real close to the FAB9 intake front runner, people in the US says it does fit with the FAB9 intake, except for one person who said it slightly touched.......so there is that.....LOL..... As it seems that I am the first in AU to have this combination of parts there's no local knowledge about fitment, so I'm just a willing guinea pig in this endeavour, I'll cross my fingers and toes and hope for the best In other news, I ordered stuff from China  on the same day I ordered the 23° silicone bend from Victoria, the stuff from China arrived a day ago, the 23° silicone bend is still travelling around Australia thanks to Australia Post, and "may" be here next week
    • Very good news...I contacted Racebox about it last night. My car is a 2016 so remains to be seen if it is compatible, requires a TCU swap, or is impossible.
