Something is definetly wrong with my Car!!!

Temme Wat to do!!!! :D

city driving is the answer. stop start traffic is as bad as thrashing it i reckon

+1 its worse Driving everyday stop start traffic i get like 250-300 tank if I drive normal condtions giving it to it bout half the time get like 450 atleast

i get around 320 in the full tank....guess mine is in the average mark....its just amazing how the same car has different fuel consumption...didnt expect so much difference...

Stop start traffic is a killer. I have mentioned before that my GTR which is mildly modded with over 260rwkw, I will get around 14ish l/100km but I am currently working only 4km from home and took the GTR for a week when the daily was being worked on and because the car wouldnt even get a chance to warm up I was getting 24 L/100km hahahaha must have a rich warm up cycle! I couldnt do it to the car for a long amount of time.

I average between 11.5 and 12.5L per hundred with mixed driving and under under 10 on Highway cruising, got 466km 2 weekends ago from just under 3/4 of a tank and this was loaded up with all our camping gear! This is in a r32 GTR with 300awkw

Took another measurement last week.

10.16L/100km

544.5km from 55.34L

Don't know why other NAs get worse. I do plenty of city driving.

I'm still running R32 GTS-T O2 sensor on NA R33 engine. 0w40 Castrol. Roughly 0.4 drag coefficient.

Anyone got any idea why my car would be running soo damn shit on fuel then?? Seems like everyone elses cars with turbos (I know they're not engaged all the time) are running heaps better.

Am going to check the air filter today, checked my tyre pressure last night

If you're experiencing bad fuel economy, try replacing the oxygen sensor if it hasn't been replaced in the last 50,000km (or if you don't know whether it has been replaced or not). $120ish item, extra 100km to a tank...and it's quite common for them to be worn out.

    • @666DAN sorry to bring you and old thread.     I've got my de+t done and it's all running great other than 1 small issue.    Car has remained auto with the na auto and tcm, I've used a stagea ecu with. NIstune board and everything is great other than my gear selection on the dash. It illuminates park, reverse, neutral, 3rd and 2nd when selected . But nothing when in  drive or what gear your in when you pop it into tiptronic. I'm sure there is maybe 1 wire in the ecu plug I need to move to rectify this. Do ya have any ideas?     Cheers man
    • Well I recently changed my rear axles and was thinking if I bumped anything, I have been driving the car for a while now though... But it has been raining today so everything is wet under the wheel arches. Brakes feel fine and can't hear any of the metal screamers, I had a squeak coming from one of the handbrake drums but that seems to have gone away a while ago. I was going down a hill when it lit up and I did feel the abs bite for a second and question why it did it?
    • Correct. Um. I dunno. I haven't cared enough about the way that the NA cars work to know for sure. But..... The 33/34 turbo manual cars have an electronic speed sensor in the gearbox that outputs a +/- (ie, sawtooth AC) voltage signal. That is connected to the speedo. The speedo then outputs a 0-5v square wave (ie, PWM) signal that the ECU (and any other CU on the bus) sees. The speed sensor is NOT directly connected to the ECU. So here's the problem. Your new ECU expects to see the PWM signal, but must somehow be getting a direct signal from the diff speed sensor. Which would suggest that the wiring of the NA car is not the same as the turbo cars. I think you will need to spend some time with (hopefully the wiring diagram for the car) and a multimeter to see what is connected to what. Then, presuming I am correct**, you would then want to separate the ECU speed signal input from the rest of the car's wiring, and probably either buy a speed signal converter, or build one using an arduino (or similar). That would take in the speed sensor signal and output a scaled (and suitably rearranged) signal for the ECU. ** We shouldn't presume that I am correct here, because there might be something else crazy going on. I don't think you could convert the speedo to be fed from the gearbox sensor, because the pulse rate from that sensor is probably different to the diff sensor and then the speedo would read wrongly. And this also wouldn't fix the ECU's problem either, because the ECU doesn't want to see the gearbox signal direct either (assuming that they are all on the same wiring, for some odd NA related reason, see above caveat!) Does this help? Probably not. Can you make it work? Almost certainly. With the above work. You should buy a handheld oscilloscope from Aliexpress so that you can view these signals directly. Connect up the probes and drive the car. Show photos of the screen when drving at known speeds and connected to different places, and we'll see what we can learn about it.
    • Assuming your brake pads are not worn right down, I'd add a little brake fluid. Is there any sign of a brake fluid leak?
    • Hello all,  I need of some help. On my drive home my handbrake light lit up and started flashing. When I got home I checked my handbrake sensor under the centre console and nothing seemed out of the ordinary. I have scanned my car via the consult port, no codes shown. Checked my brake fluid as well which is half full. Tried unplugging the brake master but it didn't change anything. Thoughts on what it could be? The master float doesn't seem to be stuck. My car is an 1998 ER34 sedan GT. No hicas but has ABS Photos below 👇🏾
