Hey,

i know this has to be wrong, im getting about 100~140kms per tank of petrol, ive replaced the fuel filter and cleaned my AFM and filter,

im just wondering what else could be needed to get some more kms out of the car cos its driving me crazy spending 60 buks every 2 days

Ummm... is thier a hole in your tank somewhere possibly? sounds incrediblyyy high for anycar

WTTTFFFF???

What mods you got? you checked plugs and coilpacks if not sparking properly will cause exess fuel but wouldnt do that much could just be contributing factor?

you have an aftermarket ecu? could have dropped the tune maybe?

thats crazy kms but i can get up to 600 out of a tank in my 33.

good luck with it though mate hope you fix it soon

i changed the spark plugs aswell, the coilpacks seem fine, but im not quiet sure really, i dont think theres a hole lol. im not aware of any aftermarket ECU, ive never had it tuned dont know about the dude before me, maybe i should get it tuned =\

Take it to a professional that knows Skylines, because 100-140km a tank is beyond serious, and you seem abit clueless. I get better fuel economy in my R32 GTR at the race track (150km per 3/4 tank). All I can think of really is replacing the O2 sensor, but without knowing your driving style 100-140km might be normal.

- Does it blow black smoke all the time?

- Were the spark plugs fouled up?

- Are the injectors stock?

- Is it the right MAF for your engine?

- Have you run toluene or any fuel additives that might have eaten up your rubber fuel lines?

- Is your check engine light on?

- Is the engine getting up to temp (ie 82c)?

- Is fuel trickling out your exhaust when idling or driving?

- Do you lose any fuel if the cars has been sitting overnight?

- Are any of your injectors wet or moist on the outside?

- Does the cabin stink like fuel at any time?

mate its not a tune issue, have a look at your engine bay, i reckon that you have a fuel leak somewhere. this is serious! i would say take it to your local machanic at least and get them to have a look at it if u are not too handy. Personally i wouldn't be driving it anywhere till i got this sorted. you are getting race track style km!

lol wut ? 50l/100kms ??? And I thought my 18l/100 was bad! But seriously ..no way no how, you must have a fuel leak somewhere. Does the engine bay smell like fuel ? Get it checked out asap as it could catch on fire

    • So I mentioned the apprentice, @LachyK helped take the bonnet off. We just undid the nuts on the hinges and unclipped the gas struts, then pulled the bonnet back a little as the front was catching on the front bar.  I had a good look at everything today and have removed the rams, repaired/reset the hinges and bolted it back together like it never happened. I'll do a separate write up on the repair, and I also removed the poppers from the Fuga today too to save grief down the road.....as said above it is at least $5k to repair retail. I'm also happier about my ability to prepare a race car, and less happy about Nis-nault's engineering (I can hear @GTSBoy sAfrican Americaning) because the top hose of the radiator didn't slip off.......it snapped clean off. By practice I put the hose clamp hard up against the flare on a neck to make it least likely to ever move (thanks @Neil!). I guess that puts a little more pressure on the end of the pipe as it is further away from the rad, but still, that is pretty shit. I've put it back on for now as there was a fair bit of neck still there, but obviously there is no lip on the neck any more so I don't think I'll track it again until I have a new rad. Speaking of which....more research required. It looks like Koyo makes a standard size radiator in ally which I'll grab in the meantime, but I really want something thicker so might have to go custom in the medium term (ouch) Coolant still needs a refill and I have the pressure tester on it over night, but other than a wash down of the engine bay it seems alright. And @MBS206 noted something noisy on the front of the engine and I think I agree....time for a new accessory belt and tensioners I think.
    • our good friends at nismo make a diff for it, I have one (and a spare housing to put the centre in) on the way. https://www.nismo.co.jp/products/web_catalogue/lsd/mechanical_lsd_v37.html AMS also make a helical one, but I prefer mechanical for track use in 2wd (I do run a quaife in the front, but not rear of the R32)
    • What are we supposed to be seeing in the photo of the steering angle sensor? The outer housing doesn't turn, right? All the action is on the inside. The real test here is whether or not your car has had the steering put back together by a butcher. When the steering is centred (and we're not caring about the wheel too much here, we're talking about the front wheels, parallel, facing front) then you should have an absolutely even number of turns from centre to left lock and centre to right lock. If there is any difference at all then perhaps the thing has been put back together wrongly, either the steering wheel put on one spline (or more!) off, and the alignment bodged to straighteb the wheel, or the opposite where something silly was done underneath and the wheel put back on crooked to compensate. Nut there isn't actually much evidence that you have such a problem anyway. It is something you can easily measure and test for to find out though. My money is still on the HICAS CU not driving the PS solenoid with the proper PWM signal required to lighten the load at lower speed. If it were me, I would be putting either a multimeter or oscilloscope onto the solenoid terminals and taking it for a drive, looking for the voltage to change. The PWM signal is 0v, 12V, 0V, 12v with ...obviously...modulated pulse width. You should see that as an average voltage somewhere between 0V and 12V, and it should vary with speed. An handheld oscilloscope would be the better tool for this, because they are definitely good enough but there's no telling if any cheap shit multimeter that people have lying around are good enough. You can also directly interfere with the solenoid. If you wire up a little voltage divider with variable resistor on it, and hook the PS solenoid direct to 12V through that, you can manually adjust the voltage to the solenoid and you should be able to make it go ligheter and heavier. If you cannot, then the problem is either the solenoid itself dead, or your description of the steering being "tight" (which I have just been assuming you mean "heavy") could be that you have a mechanical problem in the steering and there is heaps of resistance to movement.
    • Little update  I have shimmed the solenoid on the rack today following Keep it Reets video on YouTube. However my steering is still tight. I have this showing on Nisscan, my steering angle sensor was the closest to 0 degrees (I could get it to 0 degrees by small little tweaks, but the angle was way off centre? I can't figure this out for the life of me. I get no faults through Nisscan. 
    • The BES920 is like the Toyota Camrys of coffee machines. E61 group head is cool, however the time requirements for home use makes it less desirable. The Toyota Camry coffee machine runs twin boilers and also PID temp control, some say it produces coffees as good as an E61 group head machine.
