so tell me how TSB is. i dont want to register to view gay shit.

 

My impala would pull down 32 on straight highway drives before the ethanol mix, last trip to Ga it pulled down 27. My camaro which had the same engine as my impala and weighed less than 200lbs difference would pull down 24 around town. The impala is getting 19. Sounds like a pattern forming to me

Edit:
My bike doesn't seem affected by it though, I wonder if it's the smaller displacement, higher rshared_pm range, wasted spark ignition, or some combination of those

 

See that pedal over to the right? Take your fucking foot off of it.

 

Thats the mpg I got on a FL to NC trip. Only mods are catback lid and filter, Short shifter too but that doesnt matter. At 75-80mph I was getting those miles. Then again the T/A is more aerodynamic then the z28

 

the fire birds always look it but the cd numbers never back it up. frontal area and how it puts the air back together off the rear window has the most effect. a pointy nose only looks better. so thats not it. i will say the 87-90 wing was better than the same years camaro, but they gave that up for the look from 91 and up.


unless the exhaust mod leaned it out a lot, im just going to call bs. im the king of hypermileing. haha,

 

not that i know off hand what year E10 became offical but ive had mine since it was new in 02 and my milage has never changed. it still advs around 18/25 whenever i check.


its been a while since ive read the papers, but the E10 stoich is 14.1 and our cars still target 14.7 at cruise and part throttle. so we are really running leaner on E10, so it all about adv out in real life daily driving. at wot is where the big differance is. but most stock tune cars run on rich side at wot to stay safe over a production run. so its normally ok too to do wot runs on the mixture that leaner than what a 100% gas mixure would be, since 10% isnt to much. now E85 needs a lot more fuel to run the right mixure. oddly enough since its like 115 octain, the flex fuel cars can run it really lean compaired to gas and add a shit load of timing and cruise really lean while dumping tons of egr in so keep the cat alive and it gets good mpg. the last rental i had in CO where i could find E85 almost everywhere was a flex fuel car, it showed me about 4mpg difference while being half priced at the pump.

you prob just need new o2's in the car, over their life time as they wear out, they tell the ecm less voltage which means leaner, so it adds more fuel.

 

oh and your car should be a wasted spark coil pack setup too, but it might not be. if its not its better because the coil packs have more dwell time between discharge. the compression, port/valve design would have more effect on the bikes combustion prosses than spark. even those the 4valve prob does allow for a much better spark plug placement than the 2 valve car head.



fak ive wasted way to much of my life chasing hp.

 

Dont forget the Lid and filter...

Seems to me your cars sick...

 

And just think, you could've just bought a Mustang and been done with it.

 

Wait for it...
