Absolutely. I've been running the LE5 TB for months now, and my car is smoother off idle and around parking lots than our other Redline that's got far less mods and power.

Hang in there guys with a lot of this LNF stuff, I've got a little idea that might help all of us.

The new phone book's here, the new phone book's. I'm somebody now...

**silverbullet08** · 03-25-2011

Yes! new beta is here! now im just waiting on this stupid thing to download it! 38%.......................39%..................... .....40%................lol its taking soooo long

**kuprito** · 03-25-2011

Installed on my computer and don't know what to change!

**T-Man** · 03-25-2011

Just received mine but left the tuning laptop at home... DAMN!

Edit - Meant to say, as I've shared with other members, I plan on playing with this all weekend as I've finally got some free time and work hours are slowly reverting back to "normal". Anything that I happen to "figure out" will be readily shared unless someone else beats me to it.

Best of luck to everyone and happy testing!

All it takes is a little tough love and we get what we want..

Gotta love the riot starter

Some of you can thank me via paypal ...

I don't know where to begin either, in a good way LOL. (I actually know exactly where Im beginning, full e85 HPT only)

**fr0stb1t3** · 03-25-2011

I lol'd a little bit. Thanks for the new toys guys, even if they are a little late

**Bill@HPTuners** · 03-25-2011

I just figured he was jacked up on Mountain Dew.

I chuckled too, showed they hustled! lol.

Seriously, thanks and excellent work. Just went thru it all and I plan on testing with full E85 tonight

**1080112520** · 03-25-2011

so i have a good question i hope to run the full e85 tune will we have to set the desired fuel pressure mpa to 19.320/ which would be 2800psi to get the fuel we need or will we need to be a tad bit higher or less.... .. Just a question.

**DoMiStIc_RuSh_06** · 03-25-2011

i just downloaded the new version. I dont know what to do with any of it lol. Wish someone lived close to me so they could help me out. I would really love to learn how to tune on my own

I will be looking forward for a tune in the next 2 weeks.

**BowTieTillIDie** · 03-25-2011

I am so lost I feel like a 5 year old in the Mall of America..

If anyone gets this stuff squared away before this Sunday I would appreciate it ... Going to a circuit track for the first time this weekend and will have the chance to run an E85 Trifecta car with almost the same mods ..

**Ch1ck3n** · 03-25-2011

I didn't get mine yet

I wish I had my car too

I had the best luck at 2200 psi on TF's layer but still couldn't do full E85. Much luck to you! I'm back on 60% cornsauce.

Anyone do a compare between GMS1 and normal yet to see how GM changed the parameters? I don't have a copy of the S1 tune laying around to do it.

EDIT: Just found one. GM's changes under the turbocharger settings for torque management are very interesting. May be a good place to start. Also a different Injector Pulse Multiplier. The Proportional Max table looks like it may be responsible for some of the mid range boost we lose without working the DAL and MALTs hard.

If you look at the prop gain table, it does the same thing. But the GMPP prop gain table increases just about everything to hold more boost in the higher rpms.

The highest load column on the spark tables/optimum engine torque/etc is raised on the stage tune... has it always been that way?.. or did i just now notice..lol

I don't see any changes in the kappa gmpp files, only some minor wastegate duty cycle. Which files are you comparing?
