E47 tune
 

for all who dont know a E47 tune is a tune based on a fuel mixture of 1/2 tank of E85 and 91 or 93 octane fuel so for me it is 93 octane which i run all the time anyway

been running on a E47 tune and i have to say i didn't want to do it but now that i have i LOVE IT.

tune is awesome. the power thru all bands is very nice and the extra HP, well who is to turn down the extra HP
first tank got me 20.5 mpg w mostly city driving (90%)

yesterday i also put in a 18 inch 3 inch resonator and it will make it where ShagySS is good for Uber driving. i may have to change the springs back if i get complaints on the ride being too stiff w the Pedder's springs and shocks i am running
adding the resonator put a lil more in the bottom part of the tune which i like

i have a Kroger literally about a 1/3 of a mile away and fill up there often cause it is where we get groceries and get that discount
i have a cable and a laptop in the car all the time so no worry

It is sweet...:twothumbs:
30 HP , & E47 makes your engine last longer, as a slow burning fuel,
with no knock, makes for a happy engine.:thumb:

Been running E47 for 5 years, & just turned 25,000 miles yesterday...:smile:
Still running super strong , with Zero issues, & miles-of-smiles...:smile:

Hay, with you being a dealer for Trifecta , hopefully you can convince others,
to go E47...:corny:

I can buy it here now, but I don't even want to ask Vince for a tune. Think I will get HP tuners, and try the tune my buddy sent me, and call my Trifecta experience money under the bridge.:thumb:

your right 2005. i was shocked at how much better it ran and how smooth it made the engine in all power bands
it really is nice

sorry it is like that Sam. it really shouldnt be

any reason not to go straight E85?

if I put in a bigger turbo and a cam then i would go full E85. i wont do that

Not much return, running straight E85, with a mildly modded stock
turbo LNF, E47 = 30HP , E85 = 35HP
E47 has been proven over many years, to be the best choice, for a trouble free, & worry free increase in power, on the LNF engine...:twothumbs:

For anyone doing their own tune with HPTuner, shoot me an email,
& I’ll send you my E47 “tune”, for you to compare with, & to help you,
“tune”, your own E47 setup.:corny:

The “base” for my “tune” is the 3 bar GMPP factory performance upgrade “tune”.
It’s been a work-in-progress, for 5 years, & 25,000 miles.:twothumbs:

Just this month alone, I finally tackled the Optimum Spark tables, with the
great advise, from some really smart guys over on the HPTuner forum.
It really has improved the mid-range, & I now idle at 10 degrees.
Without the help from those guys, this 61 year old, would never have figured
any of this stuff out.:bow:

Also, I reworked the auto shift points this month, to really improve daily driving.
This E47 “tune”, is really smooth, & powerful on the street.
Makes my “buggy”, a really fun mild mannered daily driver.
E47 is the “bomb”…:steering:

The great thing about an E47 “tune”, is that most of it is the same “tune”, as a straight gasoline “tune”.
The “Fuel-Constant”, & all the “Spark-Tables”, is really the only changes needed, to “tune”, to the fuel of your choice…:smile:

awesome info 2005
thanks for the posts

I almost forgot, what Ethanol is really all about.
TORQUE
Along with the 30HP increase, for a conservative E47 "tune",
you get a 60 ft lb torque increase...:twothumbs:
No other mod, will bring the massive amounts of torque,
that Ethanol brings to the table...:smile:

Here's a dyno graph from a HHR SS on Ethanol.
467 ft lbs of torque, almost as much as a 2013 Z06 LS7 engine, which has 470 ft lbs of torque...:roflol:
Just look at that beautiful torque curve.
She really has nice curves…:D

CJ, I really hope that you can offer Trifecta E47 "tunes", to the guys that have Ethanol in their areas.
It really puts a "grin", on your face, everytime you drive your buggy...:D
