I've never understood this economy thing... My R33 is dead stock, 1993 so it can't be the "1.5" version, backfires on every gear change (practically) so its gotta be running rich, but I still get 440kms CITY driving, 580-600kms country driving (180kms flogging it!)

That's filling up just over 50 litres (BP Ultimate). What are people doing to get these 250-300km/tank figures?? Or is it more a case of "boost addiction"??

Lol,

I dont know about r33, but mine getting around 350-400 km fuel tank.

Is there something wrong? I use normal boost

Anyone got any idea? please help

but last time at dyno, My car showing rich fuel it still giving me 350 km pert full tank so i guess my stock r34 need fuel controller

    • Sorry I haven't been following all the detail, so you may have tried this. Does it idle with the tiniest bit of throttle you can add? You've mentioned the IACV, does it have an AAC valve and have you adjusted it at all (ie, screw the idle adjust screw all the way in, then back it out a couple of turns until idle is stable)?
    • My bad, I unplugged the one underlined in red instead of yellow before. With the car started, after unplugging the IACV (the one underlined in yellow), it idled at around 400/500 for 3 seconds before stalling. Attempting to start the car without the IACV will not start the car.   It does stutter and sputter for around 5 seconds before dying. However, immediately after starting it, you can already hear some slight sputters from the exhaust.   It won't start with the AFM unplugged. If it is when the car has already started, it stalls in a few seconds.   Yesterday, I did take some logs using Nistune of 3 scenarios. Car idling till it stalls Car idling and unplugging the IACV Car idling and removing the AFM I also have some previous logs of when the Car is idling till it stalls and when driving and it cuts. I am not really knowledgeable enough to understand what to look for. After every test, car idles rougher and rougher, until I have to stop. It will be fine the day after.
    • There is no difference between a 17x8 and an 18x8. The total diameter of the tyre needs to remain +/- the same (so you don't mess up the gearing, speedo reading, and clearance when turning front wheels..... so you just need to use a lower profile tyre on th 18 than you do on the 17. /rocket surgery.
    • I thought the same to start with. But then I thought it was one of those LCAs where the end of the ARB goes through a bushing in the LCA itself, instead of having an end link.
    • Yeah - I mean, go the other way. Smaller range. Not larger.
