Hey all

Just a quick question does anyone know how to fix my problem ?

My r33 gts t runs on e85 even tho its an awesome fuel im only getting 3 1/4z of a tank out of it once i go past that last 1/4 it leans out like im running out of fuel im still gettin 450-480 kz out of a tank if i dont boot it to much :-) the last owner was the one that converted it so i dont know if the fuel pump has been changed for the fuel do you think this could be the problem any help would be gr8

Cheers

im guessing its something like a bosch or something and cant pick up right from the bottom, i had to change my pump (stock) to and 040 (my decision) kinda overkill atm cause im not pushing tones of power but it sounds like that could be happening to you,

but i guess others can help out more, you prob need to find out what pump you have

Cheers matt i axualy have about 500-510 hp at the wheels so im thinkn there might be some upgrade on the pump ( not shaw if a stock one could pump that hp out ) if it does come down to being that problem i might have to upgrade...

doubt stock could.... if its only happening when its getting below 1/4 then just fill up earlier, i can run under a 1/4 but i dont have anything to monitor what my fuels doing, running lean ect, also it depends how low the pump is mounted, i think its best to find out what you have... cause without knowing exactly it could be something else. if you compare stock, or walbro pumps vs something like a bosch you can see why it cant pick up fuel low in the tank

Thanks mate i do fill up earlier now but being my daily driver im goin to the petrol station twice a week...now i know others dont have the same problem with the fuel i know it must be something to do with the car or the pump....

Your fuel gauge is f**ked.

If you're getting near on 500ks out of a tank, even going light on the wellie, you're doing very well and likely running the tank just about dry. My 33 on 98 would struggle to get 400 and my Stag on 98 gets ~430.

The fact you're on E85 means you're potentially using up to 30% more fuel than you would on 98 meaning you're running the equivalent of about 600ks from a tank. Your car is magical. There's a leprechaun under bonnet and he's pissing E85 into your intake.

Readjust your brain to accept that 1/4 = empty and you'll be right.

just to clear it up im on 98 not 85,

also what the above guy said could be right too, i didnt realise you were making that many kms per tank as is, my car untuned with the 040 is getting 360-380 per tank, filling up early cant remember what i was getting from a full tank... but the 360ish means about 11.5L/100kms... so yeah i think the post above is right, fuel gauge

Im amazed no one has asked. How many litres do you put in when it is at "1/4"?

Lol 500k's per tank is awesome. All highway i get 400-450. Heavy foot driving, fuel? My car thinks its water haha

true, sorta just noticed he didnt know what the pump was and thought that was the issue, i also didnt realise he was getting an awesome amount of kms to the tank!

Sorry champ thanks for your input no i didnt know what pump its got i cant stick my head in the tank can i i only got this car about a month ago and after i run around after 3 kids afternoons and weekends i dont get time to work on my car as much az i want so i just stated i was getting about 450-480 kz never did i say.....500.... But once again the young smart ass keybord killers know everything

And the other blokes car must be a camel drinking water mine only drinks e85 and i know where the bouser is...

Wtf? You need to check your reading ability. Never did i call you a liar. And i asked a specific question, how much fuel do you fill when it leans out?

Oh, mine is also on e85 hero

No worries champ i will !!!! Thanks for your help

      One Headlight isn't working - Driver Side Fuse Keeps blowing

      Yeah, but knowledge of one wire's insulation worn through to short on earth implies the possibility of other wires doing the same. I had my power steering die, because the wire that runs to the solenoid valve on the rack runs in the same loom as the power wire for the O2 sensor. And when the O2 sensor/wire did something stupid and burnt part of that loom to death, the only indication was the shit(ter) fuel economy and the heavy steering. It took deep excavation of the looms in the bay to find the problem. Not wear through in that case, but similar shit.

      Ah, I thought he'd wired it to one of the spare ECU inputs! Too long ago since I read that post, ha ha. I've been arguing with radiators, harmonic balancers, alternators and rust since reading it.

      Correct. The ECU cannot read oil temp. (Well, I think it probably can in some situations. I did have the thought of potentially repinning the ECU when I was doing oil pressure). I am using this into the MPVI dongle, so that the MPVI dongle can read oil temperature. It is attached to a VDO gauge which is obviously calibrated to whatever curve the sender actually is using. This would be easy if I could setup a table of voltage to temperature like many sensors, but it appears I cannot do this and can only setup the transform rule which appears to be Input (voltage) x Multiplier, and add an offset. This to me means it MUST be linear. So it may be a complete waste of time wiring this into the ECU. The idea was that the MPVI3 has standalone logging. I wanted to use this instead of a laptop with serial cable (for wideband) for long datalogs. Given the wideband also has electric interference, I may never trust this either in a world where the serial wideband and the analog output wideband do not agree. Last time I did a trace I could see the two wideband traces follow each other, but one was a little leaner than the other. I plan on playing with voltage offsets and actually driving the thing to see how close they correlate. If they never correlate... then, well, maybe I'll never use either. Ideally I'd like to have the Analog wideband read ever so slightly leaner than the serial one, because the serial one is 'correct'. Tuning the car to be ever so slightly too-rich would be the aim. Not needing to have a laptop flying around in the footwell connected with cables is... an advantage. About the only one from the forced upgrade to MPVI3.

      Hopefully not, since he knows the fuses work ha ha ha

      I don't think he's got it on a gauge and on the ECU. I think he's got it on the gauge and on the HPTuners DAq thingo. Remember, we're talking about oil temp here, not something that the ECU is actually interested in for its own sake.
