Fuel Consumption (merged topic)

[rollex]

Average speed of ~15kph according to trip computer, gets me about 20-22L/100km. If I really try I can get it to 19L but no better than that.

E85 life 39.2L / 100km

 

Average speed is still ~15kph

I just switched back to 98 after years n years of e85. got over the e85 life, with the sh*t economy and having to plan my adventures all the time. it was good for the drags that's about it.

 

still getting used to 98 fumes again ahaha

Why don't you get a flex fuel tune?

Get tuned with pcmtec and this problem goes away.

 

You can run 98 all day long and when you wanna do skids just fill up with e85.

 

Edit: I was going to post this a few minutes ago from the toilet.

$1100 just for the convenience no thanks. 

 

buying a tesla instead

Depending on your driving habits you could recoup your money for flex parts/tune within 12 months.

 

Here's an example;

 

Run a 12psi 98 tune that blends into a 22psi e85 tune. Run the boost up high earlier in the blend so even at 5% ethanol it goes to 18psi but you can leave the timing out of it until the ethanol content is higher. 

 

That'll mean you'd have a fairly ordinary car with straight 98 but with even a small amount of e85 it'd come alive. 

 

It'll keep your car alive for longer too cos it'll last for ages at lower boost and even a stock motor should stay alive for a bit of high boost work.

 

You'd definitely save some money running 12psi on 98 over 22psi on e85. #fueluseagethread

 

Also a random idea @rollex how about a secondary fuel pump output that is activated by various tunable conditions and/or parameters such as map and ethanol content.

Just did a 1100km trip down to South West WA , with some mixed driving conditions, dirt roads ( slow ), some undulating hills.

 

I was very impressed with the Fuel use over that period with air conditioned on, warm outside air intake ( not great for Economy ) and still managed to get 8.6ltr/100km

 

over that 1100 km trip. Very good for a 4-ltr turbo running on 95 octane.

 

Round town only varies a lot, as to be expected -

[XR6T 520RWKW]

I have a 2010 Xr6 FG Turbo  and its Manual.

its tune to produce 520 RWKW or over 700 HP.

My ECU tells me my average Fuel consumption is 22 Liter or little higher

Petrol I put in is E85 from United

I drive in heavy and light traffic, on high ways, local road. I do all kinds of drive apart from country driving.

car has done only 85 KM.

my normal range is about 340 km on average on combined .

planning to down tune it

 

Just wondering what is the Range on 1 of these thing (stock or none stock from 2008 over)?

[ilk]

1- I  get 400km to a tank, I have 285rwkw

 

2-  you use Ethanol so roughly you are going to use 30% more fuel already.

 

3 -why are you driving a 520kw car that runs on ethanol and concerned about fuel economy.

 

4 - just use less throttle if it's too much power for you, right foot, control it.

 

5-  are you taking the piss out of us? Serious question because I highly doubt a car enthusiast with that amount of work done to their car would even ask that question.

 

 

Happy to help❤

 

A stock one would probably get you the same km, 400 ish, it's all in the way you drive.
