E24 is my 'winter' tune. 1 part E85 + 4 parts premium 91/93 gasoline. 20% E85 + 80% 91/93 gasoline one gallon of E85 + 4 gallons of 91/93 gasoline
E47 is my non 'winter' tune. 1 part E85 + 1 part premium 91/93 gasoline. 50/50 or half/half, equal amounts of E85/gasoline

These tunes are for your enjoyment, to show you what works for my 'buggy'.
Remember, these are my tunes that rock my 'buggy'.
Use these tunes at your own risk!

The E47 tunes are also great for any blend of Ethanol from E47 to E100.
You just need to change the injector constant in the program + upgrade your fuel system components ot provide more fuel volume.

 

Awesome of you to share your tunes! I guess my 2011 would have a factory tune for E85 as I have the flex fuel system. I’ve never put E85 in it

 

These are for an upgraded K04 turbo, which is machined for a bigger 'wheel'.

This modified stock LNF turbo is called the: K04r , K04+ , or the big wheel K04

 

Y not?
E85 will give you more power, & your engine will run smoother, cleaner, cooler, & last longer.

 

Not seen any E85 at the pumps here.

 

Stock GMMP tunes for you to try.

You need to purchase the 3 bar sensors plug N play kit to try the 3 bar GMPP tune.

Post your tunes here in this thread for our enjoyment

If you run E24 ,use .03100 for your injector constant & .03355 if you run E47

 

My racing tune that I use at the track, which got me a best of 12.28

The CobaltOverbooster starter tune is from a guy on the Cobaltss forum that knows his stuff about tuning our LNF motor.
He's one of the top 5 tuners, & provided a basic 'starter' tune for everyone to use & learn from.

UPDATE:
The GMPP is the best 'base' tune to use for our 'buggy'.
All of the tunes that I have posted, (except the ColbaltOverbooster tune), use the GMPP base.

Why/
Because the GMPP 'base' has extra built in turbocharger protection.
It's probably the main reason that I have'nt blowen up my turbo over the last 12 years.
So, that being said, you need to do a 'write-entire' to change your 'base' to the GMPP 'base'.

 

Awesome thanks for sharing this information

 

thank you sir!!!!!!!

 

I’m no expert on tunes, but, “E85” at a gas station is probably not 85% ethanol. While the concept was originally 85% ethanol, last I heard the standard range is 51-83%.

So, E85 can be as little as 51% ethanol anytime, and is almost certainly not anywhere near 85% in cold climates in the Winter, which would cause problems with hard starting. Retailers are even advised to “blend down” leftover “Summer” stock to reduce the ethanol content for cold-weather sale.

”E47” is a tuners’ solution to this problem. The concept originated with the idea that mixing 10% regular with 85% E85 50/50 results in approximately 47% ethanol. The problem, obviously, is it ain’t that simple for aforementioned reasons. The workaround is to test for ethanol content at the pumps (the E85 and maybe the regular too, which in some places is almost always about 10%, and in others might be 0%, or somewhere between) and then calculate the required proportions, or carry a chart. This is a serious PITA for daily driving, but I suppose makes sense for low-budget racing or “recreational” driving.

Maybe there are sources for E85 that’s reliably 85%ethanol. I welcome the opportunity to understand this area better.
