Last 2 tanks ive been getting a worst of 414 @ 52 litres and then 435 @ 52 litres. The 414 had heaps of thrashings and even a few with the 435. Half tank on these i was getting between 200-220. Now im driving like a granny, and the current tank i have 240 and its still just above half.

if you get 200kms from either the top half or bottom half of the tank your doing very well.

melbourne seems to have better petrol than sydney - i always read skyline melbourn'ites averaging over 400km a tank which is around 12l/100km's, which is doable i guess...im more 12.5-13l/100km. around 400km is my average.

i have powerfc, 13psi boost, full exhaust & hiflow cat, front mount, hiflow filter element. the powerfc makes a large difference, before the PFC i was averaging about 350km per tank.

i get just around 400 and i thought that was shitty... 1st half usually goes quicker as I fang it, then realise after 1 day i have already used a half tank and take it easy.

worst I ever got was 210km out of a tank.... got 185km out 60L on an STi once :( redline the whole time almost.

I almost always get 400km and drive till the fuel light is on. She's an auto and i'm not afraid of the GO pedal, best has been 520 on a country drive with some WOT. Worst was 270, all with a cat back and no noticeable difference with modded ECU more boost and pod filter.

  • 2 months later...

I smashed my previous fuel consumption record (552km from 63L = 11.4L per/100km). It now stands at 622km from 60L = 9.6L per/100km, I could have pushed it to up around 640km but I didn't want to risk it because I was about to turn onto the M2 and wasn't sure where the nearest servo would be off any of the exits hehe.

I got the 622km just by driving from Penrith -> Canberra -> Penrith -> Seven Hills. I was using Shell Optimax with a standard airbox, standard airfilter, standard turbo, 7psi boost and it was pretty much about 550km of pure 110km/h highway driving (5th gear doing 110km/h @ 3,100rpm) and 72km of normal driving (happy laps around Canberra Summernats). and 1 extra passenger with luggage (around 160kg more than I normally carry).

I'm pretty happy with that result because its still only the standard ECU so with a PowerFC and a good tune im sure it would go beyond 650km but I won't know until 2005 when I go to the Summernats again hehe.

I get round 220-240kms on half tank, but i dont usually throttle too hard (too many cops in my area). Got apexi pod, custom hiflow cat and cat back 3.5 inch, AFC. Car's poorly tuned atm. Dont know why, but when I do go hard the fuel difference is not very much, prob drops to round 200kms on half tank. Always thought that my car drank too much for the amount of go it gave compared to a mates 180.

    • If as it's stalling, the fuel pressure rises, it's saying there's less vacuum in the intake manifold. This is pretty typical of an engine that is slowing down.   While typically is agree it sounds fuel related, it really sounds fuel/air mixture related. Since the whole system has been refurbished, including injectors, pump, etc, it's likely we've altered how well the system is delivering fuel. If someone before you has messed with the IACV because it needed fiddling with as the fuel system was dieing out, we need to readjust it back. Getting things back to factory spec everywhere, is what's going to help the entire system. So if it idles at 400rpm with no IACV, that needs raising. Getting factory air flow back to normal will help us get everything back in spec, and likely help chase down any other issues. Back on IACV, if the base idle (no IACV plugged in) is too far out, it's a lot harder for the ECU to control idle. The IACV duty cycle causes non linear variations in reality. When I've tuned the idle valves in the past, you need to keep it in a relatively narrow window on aftermarket ecus to stop them doing wild dances. It also means if your base idle is too low, the valve needs to open too much, and then the smallest % change ends up being a huge variation.
    • I guess one thing that might be wrong is the manifold pressure.  It is a constant -5.9 and never moves even under 100% throttle and load.  I would expect it to atleast go to 0 correct?  It's doing this with the OEM MAP as well as the ECU vacuum sensor. When trying to tune the base map under load the crosshairs only climb vertically with RPM, but always in the -5.9 column.
    • AHHHH gotchaa, I'll do that once I am home again. I tried doing the harness with the multimeter but it seems the car needed a jump, there was no power when it was in the "ON" position. Not sure if I should use car battery jump starter or if its because the stuff that has been disconnect the car just does send power.
    • As far as I can tell I have everything properly set in the Haltech software for engine size, injector data, all sensors seem to be reporting proper numbers.  If I change any injector details it doesnt run right.    Changing the base map is having the biggest change in response, im not sure how people are saying it doesnt really matter.  I'm guessing under normal conditions the ECU is able to self adjust and keep everything smooth.   Right now my best performance is happening by lowering the base map just enough to where the ECU us doing short term cut of about 45% to reach the target Lambda of 14.7.  That way when I start putting load on it still has high enough fuel map to not be so lean.  After 2500 rpm I raised the base map to what would be really rich at no load, but still helps with the lean spots on load.  I figure I don't have much reason to be above 2500rpm with no load.  When watching other videos it seems their target is reached much faster than mine.  Mine takes forever to adjust and reach the target. My next few days will be spent making sure timing is good, it was running fine before doing the ECU and DBW swap, but want to verify.  I'll also probably swap in the new injectors I bought as well as a walbro 255 pump.  
    • It would be different if the sealant hadn't started to peel up with gaps in the glue about ~6cm and bigger in some areas. I would much prefer not having to do the work take them off the car . However, the filler the owner put in the roof rack mount cavities has shrunk and begun to crack on the rail delete panels. I cant trust that to hold off moisture ingress especially where I live. Not only that but I have faded paint on as well as on either side of these panels, so they would need to come off to give the roofline a proper respray. My goal is to get in there and put a healthy amount of epoxy instead of panel filler/bog and potentially skin with carbon fiber. I have 2 spare rolls from an old motorcycle fairing project from a few years back and I think it'd be a nice touch on a black stag.  I've seen some threads where people replace their roof rack delete with a welded in sheet metal part. But has anyone re-worked the roof rails themselves? It seems like there is a lot of volume there to add in some threads and maybe a keyway for a quick(er) release roof rack system. Not afraid to mill something out if I have to. It would be cool to have a cross bar only setup. That way I can keep the sleek roofline that would accept a couple bolts to gain back that extra utility  3D print some snazzy covers to hide the threaded section to be thorough and keep things covered when not using the rack.
