HP Tuners / EFI Live Updates

[GJohnson7385]

Almost every turbo application(from the factory) has a huge upside, with cobalt TC's guys were making 40+hp & 70+ ftlb with tuning alone...on a 1.4 I could see 20/40 being a reasonable scaled guesstimate. Really depends on how much room there is for improvement in stock form...

Ehh this is true but it comes with a price....People may not be seeing any issues right now but running this small turbo at 22psi is going to catch up with it...Our turbos are only suppose to support 16psi max...This is my 3rd turboed car and my first one 2003 GTI 1.8T i did this same thing to that small turbo (KO3 Sport) Built for max about 16psi and I ran it at 23 psi and sure enough, a few thousand miles later, it blew.....I also had a SRT4 but put in a 50 Trim turbo swap (built to support 30psi@500whp). Its fun to max out your turbo way beyond its means, but the price to play will come along with it....

I agree, I think this is where aftermarket support will need to come into play, it turned out ok for the cobalt tc guys and I'm sure someone will be able to come up with a larger turbo option for you guys as well.

cut and weld something must be pretty easy to swap in there:

Someone has come up with a larger turbo for the Cruze 1.4T.

I do not know if this would work on the Sonic.

FYI - EFI Live has 2012 Cruze support out now. The support folks say the 2012 Sonic and Cruze use the same OS, so in theory the Sonic is now tunable with their product.

I'm going to give it a couple months and see if HPTuners can get support out before I make a purchase though.

Support for both the 2012 Cruze and 2012 Sonic was made in a recent software release. Based on customer feedback, additional tables have also been mapped and added.

We've been getting great feedback from the folks tuning the 2011 Cruze turbos over the last year, and more recently the 2012's. They have way too much timing from GM, with a tweak of a few tables you can get about +4 PSI of boost with no hardware changes, and some are seeing gains of +30Hp at the wheels.

Virtual VE tables are included in our latest release, and flash times are around the 20 second mark.

The next phase of development is trying to determine when we can slot T76 Transmission tuning support into our development plan. Reading the T76 was added around a month ago and we already have a good selection of files submitted.

So the guys over @ EFI Live were nice enough to send me a 2012 Sonic read, and I opened it up with their latest tuner version. Some interesting stuff I saw, which I'm sure isn't news to anyone:

1.) The OS was designed for E85/flex fuel usage. That functionality is just disabled. The OS has the ability to use a fuel tank sensor or "calculated" (via o2 sensor I assume?) amount. Makes upping the injectors and tuning for E85 a breeze since its already all there.... which Trifecta has already done.

2.) There IS a low and high octane timing map, and there is even a pair if on E85. Ditto for VE and most other tables related to performance. I wouldnt be shocked if Trifecta was just setting a bit on/off on the E85 flag for the "select a tune" stuff. There is even yet another pair for "AFM" (Active Fuel Management) mode, which I'm not sure we're using? The desceiptions say they are used when 2 cylinders are shut down.

There is a significant difference between high and low octane timing values. Think 10-6 degrees near the higher rpm/air flow cells.

3.) DFCO (Decelleration Fuel Cut Off) is only enabled between 1100 and 1450 RPM from the factory. Which explains why people don't see much fuel gain from coasting. Dinking with that a bit would help the hypermilers.

4.) The torque control is pretty nanny after 5500ish RPM. No wonder the car feels like mush near redline. In general the "fun" factor could be improved greatly by just playing with these.

Bunch of other stuff thats pretty interesting in this OS too. I'm starting to lean towards EFI Live. I'll be blunt, I think HPT might be more user friendly.... but the EFI Live product is certainly more "geek" to use, which I fall into. I know EFI Live is working on a new version of their tuner thats a little more "user friendly" to folks.

Just for reference, Trifecta Select-a-tune is for high/low boost tunes, not different fuel types

How do you like your cobalt ss/tc?

Yeah the SS/TC crowd hate trifecta. Mostly due to a certain person on the forum that tunes using hp tuners and sells the tune for a really cheap price. I won't say who but I will say that I personally have 4 customers with LNFs that went to that guys hp tune and trash talked trifecta only to break stuff. Next thing I know they are all back to Trifecta. To each his own. HP Tuners is a great product in the hands of an experienced tuner but you never know just how aggressive the tune is until something breaks and you have to foot the repair bill. I have HP Tuners myself and use it on a few cars that I'm comfortable with though.

That all being said though, I know a few guys that can do amazing things with hp tuners

Just wondering how you like your cobalt?

Do you guys get around to answering emails often ? I sent an email to you last week & was hoping to at least het a reply. At that time I was interested in your products and was looking forward to spending some cash. Hopefully the next time I'm ready we can do some business .

Alrighty...

I did more research and found out the calculated ethanol content works like so: when enabled, everytime you fill your tank the car will go into an ethanol content learning mode. However the source I researched this from noted it can take up to 90 miles for this learn to occur bunch of other gotchas too:

I was replaying bits and pieces of this post in my head over the past couple of weeks. I noticed a lot more noise from the engine on the last tank of gas. Sounds like either heavy spark knock, or heat shield rattle in 2nd and 3rd gear/2000-3000rpm/slight load.

It was much louder than anything I was hearing on the days prior to refueling. I was keeping an eye on my trip odometer, and was testing until about 80 miles or so. The next couple of days were heavy rain, and resumed testing at about 110 miles, and the noises had subsided greatly.

Today I decide to go back to Mobil 93 e10 from 3 tanks of Mobil 87 e10, drove about 25 miles testing it out, and next to no noise.

I was mistakenly thinking your post was about octane learning, and come back to see it was about ethanol learning.

Is there an octane learning mode? I kept thinking to myself it should adjust in realtime from the knock sensor.

I answer within 24hrs usually, can you resend the email? It probably got stuck in my spam filters or something. Sorry :sadbanana:

awesome thread Gimpster.

have there been any more recent updates on either tuning software?

a friend owns a tuning shop and i know he uses hptuners on the LS motors that come through, so him just knowing that software would be good. The EFI live though having a flexfuel, though maybe really shetty version, is about the biggest thing getting me excited.

otherwise, maybe i'll dig in myself. i've always considered myself a wrenchturner rather than a tuner though...
