High idle will affect your economy a lot if you do a lot of stop-start traffic. Try getting it down below 800. Other than that, just do the usual stuff - replace plugs, clean injectors, etc. Does the R30 use an AFM? If so try cleaning it with some electrical contact cleaner.

Aftern owning a sr20de silvia for 3 years and getting around 450ks from 45L of fuel it was a big shock how much fuel my r33 uses. The best figures i have gotten are 11L/100ks on highway driving. I average 13.5L/100k in the city but have had it as high as 18L/100ks after a night of hard driving. I guess a relativly heavy car and a 6cyl turbo doesnt help with fuel consumption.

The best ive ever got from my R30 was something over 400kms out of a full tank. Prettymuch i trash it everywhere, so i dont think thats too bad.

Things that i have done are, new plugs, leads, rotor button and distributor cap.

Other things that will help are cleaning the injectors (one of the best things is to put a bout 250mls of Auto-Trans fluid in the tank next time you fill it up), between doing this and replacing the fuel filter it will make a big diference.

The other thing that everyone with a L24E in a R30 should do is to cut the airbox.

I removed the shitty restrictive cold air feed piece of crap and cut a big hole in the top of the airbox, ill post pics soon.

This made a big diference in power, its much quicker, revs smoother and sounds totaly nuts. I couldnt beleive the diference it made. with the standard exhaust still in place i (Quiet out the back) i have had people ask me if its a V8, others are convinced there is a hole in my exhaust! dickheads.

seriously try going for a drive, just take the airbox lid off and go for a quik spin, youll know what im talking about.

yeah i used to get atleast 450Km out of it, but now about 350 - 380 Km's even with highway driving, so i'll check it out!!

noticed alot more noise in the engine since the super synth mobil 1 went in, so see how this affects the sitution before regapping, as fuel consumption was (i think) ok before the oil change!!

      Leak from Tokico BM50 Brake Master Cylinder

      HFM BM57 has a "bad" knee point, IIRC. It's not the same thing as the later R chassis MC.

      The ATTESSA is functionally identical to R34; there were a bunch of JDM models that continued ATTESSA including Fuga/Q70, Skyline/Q50, Cima etc as an option. All with Auto only and I think mostly for snow regions. AFAIK there were no AWD VR30DDTT sold in Australia - it is on my to do list to check regs for racing a LHD car in Targa/ATR/AASA/CAMS events because if I can get the auto to work it would be interesting to run a 4wd car The Ecuteck TCM tuning is the same model as their ECU tuning, they already have it for R35 and Dose's favourite, BMW. You buy "points" to allow your computer to be tuned, buy either a bluetooth (phone app) or bluetooth+USB+Key (phone and PC) dongle, and pay for a tune that will be locked to your tuner ( ). You can also access the tuning software yourself but 1. it is mega expensive and 2. these computers have a billion parameters that intersect, so how could you ever spend enough time on it to get a decent result.

      Or, is it a case of what it is like owning an R series Skyline? NFI what the previous owner has done or fiddled with... Ha ha ha After reading through this thread, I went on a bit of a research about the Q50/Q60. Now I'm quite intrigued by them! Is the AWD in them more like a WRX where it's always AWD, or is it more like the ATTESSA in the GTRs? By the sound of this TCU tuning, this sounds like a case of someone has made some real software for it, and you just need the right piece of hardware, and then you license that specific vehicle/TCU. Or is this a case of the software will be really expensive so only a few tuners have it, and you still have to pay a license per vehicle?

      By popular demand.. it was a coil. Got my hands on 1 new OEM coil, replaced with the one that made the less noise difference when I unplugged it while the car was running and started the car up. No stutter and the engine light was gone. I guess I’ll buy the other 5 they have lol

      No, code 21 is very straightforward. It can only be the things described in that diagnostic flow. In fact it has no way of knowing that the spark plug resistance is out of spec.
