fuel consuption is killing me
Damn, how far can you drive with 1 fuel tank? I can only drive about 170 miles until the tank is empty. 
Also when I drive it realy slow and boost never goes above 10psi it needs that much fuel.
This is with a/f ratio 13:1 on 720cc injectors.

Re: fuel consuption is killing me (austrian type-R)
that's it? Perhaps they should have tuned your part throttle settings higher up, somewhere around 15:1 for very light loads and gradually increasing with higher load

Re: fuel consuption is killing me (VaporTrail)
Yep, thanks to Vapor Trail, I got about 360 miles to a tank...highway miles until about the last 20 miles, then it was showing what my little car could do to those crustangs. hehe Im happy with my gas consumption....for 500cc injectors anyways....

Re: fuel consuption is killing me (GSRwBOOST)
part throttle is 14.1:1
Haltech ECU
360 miles with one tank? Damn, even with stock engine this was not possible. With 190bhp stock engine I reached maximal 250 miles.

Re: fuel consuption is killing me (Etylorcen)
Yep, I drove all the way from Miami to jacksonville, and still had gas left over to get jiggy wit it. haha. The key is to keep your eye on the vac. i try to keep it steady and not accelerate at a high rate.

Re: fuel consuption is killing me (austrian type-R)
This why i went with the E-ram... i have seen at LEAST a 15% increase in mileage and with decent power gains i might add..

Re: fuel consuption is killing me (GSRwBOOST)
I get 300 plus miles with daily driving, I run 78 miles round trip to work on side roads not highway. I'm not fully tuned yet so it should get better or stay the same.

On the other hand stock I was hitting 280 at the best...
Just my 0.2 cents...

Re: fuel consuption is killing me (Arturbo)
Dont forget you are running batch, rather than sequential on your haltech. I told you this was gonna happen.

Re: fuel consuption is killing me (Arturbo)
okay, maybe this is one reason, but I realy doubt it is that much of a difference. 1 litre more per 100km, I don't care, but 6 litre more, than before sux!
What is with newgsr? He needs nearly that much fuel than me. And don't forget, I was burning more fuel with my stock ITR, than you boosted guys. Something is wrong here, perhaps my driving-style.
Stock engine: about 220 - 250 miles per tank
JRSC setup 240cc: about 210-240 miles per tank
JRSC setup 310cc: about 190 - 220 miles per tank
Turbo setup 440cc: about 180 - 200 miles per tank
Turbo setup 720cc: about 155 - 180 miles per tank
I think larger injectors are dumping way more fuel into the cumbostion camber on light partial throttle than smaller injectors ON THE SAME A/F RATIO. Deoes that make sense
PS: I don't write how many "miles per gallons", cause converting your imperial **** into our cool metric numbers hurts my head too much.

Re: fuel consuption is killing me (austrian type-R)
Damn I used to get 450 miles per 10 gallon tank in my stock DX. When I switched to the EX head and started running mysteriously rich, it went way down but now I'm getting 260-280 and I boost all day long every chance I get
ANd still running too rich! Anybody have an AEM rail mount FPR for cheap?

Re: fuel consuption is killing me (austrian type-R)
HA HA HA 
I get 38 miles per gallon on my Zdyne tuned turbo CRX (normal driving). Maybe you guys should remove some of the BLOAT out of your overweight tegs!! j/k I have gotten as bad at 16 mpg when I constantly boosted with an FMU.
That means I get to go over 330 miles on a tank. I pass rustangs in the gas station all the time.
I don't mind $2 a gallon, it still would cost me under $20 to fill.
