Can anyone tell me roughly how many k's I should get out of a full tank of fuel in a 97 RS4 Stagea in standard form.

I have just clocked my last ful tank at 360k's which seems very low?

If this is the can fault coil packs cause this high consumption as the car does not appear to be running rich. However I do have this pulsing problem over 70kmh as posted on another thread.

Does anyone have any ideas

Cheers

ok when I bought my stag the SAFCII hadn't been tuned and I was getting around 400 per tank city driving and well over 500 per tank on the open highway (drove from SA to WA)

With it tuned now, I get 460 per tank... city driving.

I've got 345 on the clock with just over a quarter of a tank to go and I'll get atleast another 100km from it.

Thats on BP Ultimate (98ron)

Thanks for that. I have a stupid question now what is the SAFCII?

Also are you in Rockingham, Perth by any chance...if so were did you take your car to get tuned.

i had shot coilpacks with my rb25. they gave chronic misfire on full throttle at 4000rpm and above. however this made me drive the car nicely so i still retained great economy.

remember it also matters how you drive it, i can get 20% better economy if i'm nice to my car.

check your 02 sensor, they're meant to be replaced every 40 000kms iirc

and google SAFCII to find out HEAPS of info :D

bugger all mate, even when working perfectly they are thirsty if your foot is heavy.

and mine is. really heavy.

mine is manual, new 02 sensor, airfilter and exhaust on the standard computer, and I am happy if I get 400klm.

About to put a power fc in and see if that helps, but I'm not expecting an improvement

360km isnt bad, honestly.

when I first got mine I got around 410kms per tank to around 55L

then tuned, a little less kms but more power

and again

and again

now Im limited to 90kms per quarter if I pussyfoot for 80% of the tank

the other 20% makes it worth it :laughing-smiley-014:

Cheers for that. I just wanted to get a handle on how thristy they are, and if my problem was fuel related.

yeah I'm in Rockingham... I took my car to Hyper drive when I first got the car.

I also run 7-9psi now too, instead of 12 lol

Super Air Flow Controller (SAFC) it modifies the air flow meter signal to trick the ECU into thinking that there is less air going in to the engine, to send in less fuel, as the stock ECU tends to run quite rich with mods. (all that info from Mitchy)

I am in Rockingham too......I am running just under 7psi boost but everything else is pritty standard. Do you know anywere local that could tune the SAFC on my car.

SAFCs will have minimal effect on your economy, as when you are cruising (closed loop) the ECU reads the O2 sensor and constantly adjusts to achieve the preset mixture. The SAFC will save you some fuel when you are hard on the throttle (open loop), where it uses the air flow meter signal. A lot of tuners won't even bother to tune the low throttle map on the SAFCs, as mine did.

Other than an aftermarket ECU the best thing to do is make sure your engine is running as efficient as possible, ie new platinum plugs, new fuel filter and pump, new air filter, new O2 sensor, splitfire coil packs and drive 'off boost' whenever possible.

you could try X-Speed in o'connor. There is noone in rockingham, only ford/holden specialists... and I wouldn't trust them to even know what a Stagea is lol

You could try GTi Performance too in Bibra Lake...ask for Simon, I'm not sure if he does SAFC's though. He is a nice guy and owns an S15 or two lol

    • 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.
