89 Gas on 87 Tune

[coolio4433]

So the gas station closest to my house has 89 for the same price as 87 always. Am I correct to assume that I could see even better performance with an 87 tune by using 89 and bumping the timing up 1.0 like folks have done with 91/93?

Is everything E10 up there?

It would work, not sure about mileage or anything. I noticed a little more kick on the upper end of the power band when I would try it. Even before the programmer.

Sadly yes :(

Everything is 10% ethanol? I thought it was supposed to be hard on the rubber parts. Or is that just the E85?

Supposedly up to 10% or so doesn't cause harm to anything. Based on that assumption lots of states in the upper midwest have adopted the E10 fuel as the standard. (mostly as a subsidy to the farmers and ethanol plants in the area)

I do like that premium fuel in WI is still 100% gas. My car gets 2-3 MPG better on that stuff than the crap I get in MN here.

In central texas you have to drive at least 40 miles to find a station that sells ethanol, and when you do it is only E85. So I've never run it, almost borrowed a gallon of a friend's jet fuel though. He'd go buy about 5 or 10 gallons at a time as an octane booster for his truck...on top of the 93 that he always ran. lol

Hey there longshot, I'm sure you meant 100 low lead av-gas. Jet fuel is more like kerosene, or diesel fuel and only used in gas turbine engines. By the way, it is very illegal to run av-gas in your vehicle, because it does still contain some lead......but man does it let you make the horse power.

[Longshot270]

he called it jet fuel, but yeah it was the av. I dont know where he got the money to buy that fuel and a new set of terra grapplers every 6 months, but he did. lol

no one checks tanks around here, not even on the tax free ag diesel.

[Down N Dirty]

Avgas is only 4 to 5 dollars a gallon......the tires are costing him much more than that. :yikes2:

[Longshot270]

yeah, he said it was about $5-6 per gallon but when you mix it rich with 93 and get about 7 mpg hot rodding all the time, the tires might not have been the bigger expense. lol

[Down N Dirty]

Maybe you can borrow some money from him to build your game room funds back up? :smiley_roll1:

[Longshot270]

haha, yeah. got up to 1000 earlier and lost it 10 at a time, only making money with the bigger bets for some reason. but it doesnt bother me, every time I get built up there is some kind of change that knocks me back down to a few hundred.:doh: lol

[Longshot270]

think my dealer is rigging the deck, he averages 21, over 4 out of 10 times, been keeping track. He also cant shuffle worth a darn either. lol

[Down N Dirty]

Maybe you should seek counseling? :hehe:

[Longshot270]

haha, yeah maybe im just going crazy:crazy:, maybe the dealer isn't really getting 21 three times in a row and that ace of clubs wasnt in the previous hand. lol

My guess is if 89 is the same price as 87, then 89 is E-10, and 87 is straight gasoline.

PS, sorry we hijacked your thread with gambling shenanigans.

Hey man, you should probably get professional help immediately! :disbelief:

Corey, may I suggest you post the phone number for gamblers anonymous on the front page of your web site. :giggle:

[Longshot270]

Did a tiny bit of looking into the E10, I wouldnt bump up the timing too much. they say .5 for every octane, I'd go .25 and adjust up in small increments from there. Most of the info I found looked like some of the characteristics of gas/ethanol were slightly lower mileage and higher heat emissions. Even found an actual study using about 15 different vehicles and monitoring lots of factors.

haha, I dont have a gambling problem in real life, just on this computer. I've won all kinds of useless stuff gambling. Most people just dont like using money.:shrug:

...never really like video games anyway, I've always told people "I shoot real guns, and drive real cars". Was at a church party ONCE where we played paintball and Halo. Should have seen the look on this one kids face when I said "go ahead and shoot me with your laser, got a gun in my truck."(yeah I meant the paintball gun, shells are too expensive) LOL

[Down N Dirty]

Hey longshot, you're a real card......no pun intended. :cheesy smile:

[Longshot270]

you should meet my parents(at your own risk). :D lol

No problem. I guess I'll just have to experiment a bit and see how it goes.

[Longshot270]

Maybe try what I mentioned earlier, increase timing .25 for every octane over normal then keep raising it until you think your close enough to the limit.

[88Racing]

That's what I thought about the Twin Cities and E10!
Don't like putting that stuff in the bike when I ride up their. Try to make it into WI where I grew up to get the straight premium again.
I would probably only go .5 on the timing.

Lars :2thumbs:

[coolio4433]

Thanks for the advice everyone.
I'll start out running a few tanks on 87 first to build a basis for comparison and then maybe try the 89 and bump the timing by 0.5 and see if it makes a difference or not on anything noticeable.

I might have to drive the truck more often though or it'll take me forever to conduct this test!

:blizzard:

(yes there might be snow on the ground by then)
