My Rb20DET around locally used to pull a consistant 470km's per tank.

All were short trips hooning to Uni and back.

Check the O2 sensor, Ecu's coolant temp sensor, dirty injectors and apparently the AFM can also cause bad fuel consumption.

Dropping the RB30DET in dropped fuel consumption to 430km's per tank.

The base map of the PFC has now bumped fuel consumption to 520km's per tank.

Leech, I fill up around the same as you. 50-55litres depending how low I run it with the light on.

 

Generally 50litres is pretty spot on with when the fuel light comes on.

yea strange i might be mistaken but i though my late generally comes on at around 46 - 48L which seems very early but meh fuel level gauges are always so dodgy i just go off how many kms :D but my car is also fairly stock at the moment only thing is a full 3" turbo back exhaust when i put the panel filter, bleed valve and fmic on i can see it dropping a bit hopefully not alot though

better fuel economy in Rb30det because of lack of throttle usage...im quite happy most of the time putting around off boost....it has the same feel as the rb20 did on boost :D

    • A few small updates since the previous post and lessons. I decided to do a little interior light upgrade on the 110. I quite like the iilumo items, even if they're a bit of a premium over other brands. You'll also note the Stedi Fogs, that will go into the S15 fog lights as I needed to match the bulbs since I got the new ones earlier. I hope they fit as the body is quite a bit longer than your normal bulb.  Annoyingly, I managed to trip the fuse, which normally wouldn't be an issue until I located the fuse. I can't say I've ever come across this. I had lucked out that someone nearby had a spare, but oddly enough Toyota dealerships seem to keep this in stock. I ordered some to keep in my stash and as luck would have it, someone else nearby tripped the same fuse so I passed on the favour.  I also did a little service on the 110 ahead of some additional work coming up. It's been annoying that Goleby's stopped carrying this particular HKS filter for the 110, so now I need to keep them on order from Japan. I also took the opportunity to install a bash plate and number plate riser. The plate riser is such a cheap but nice fix to help really tidy up the car. I'm tempted to now also replace my headlights, on this car. Both items were from Project Aero.    I also needed to replace the rear tyres on the 110, and after trying to get it aligned learnt that I need to replace some bushes in the front end, so that's next.  Closing out this update with a nicer picture as always! 
    • Yeah mate, never miss it.
    • Any going to watch World Time Attack at SMSP this year?
    • Appreciate the correction on the "ground", that will make a huge difference to looking at this. That makes complete sense about AF70/AF71 which is what I had come down to being the issue, one of these. I'll have another look in the ignition wiring when I get a chance next week. I'll also make up a jumper wire for running that AF73 test.  ECU is fine, relay itself is fine, pump harness is fine and the pump itself is fine. I am going to upgrade the Walbro 255 anyway with a DW300 I have since I need to replace the fuel sender and I'm going to upgrade the FPR with my chasebays kit ready for new plenum/injectors/dbw, but I'll get this working first. That's why this is so frustrating.
