K.I.S.S.

Just have a laptop with 2 tunes. One for an E40 blend, one for an E85 and know the computer will make up for the rest.

Uhhh... for stock-ish power levels I'm sure that's a valid option. Would you try this method at 26-32 psi? 7500rpm shift point?

If you have a proper tune, then yes. You can swap maps all day (until the ECU bricks).

I ran it with my TD04 & Evo3 16g in this manner. Got the professional dyno tune on the 16g, played around the TD04 prior. My initial concerns were fuel mileage optimization during my 130 mile commute. I was able to improve this with lean burn (1.05) and slight advancement in the cruise zone.

I've only got a 2 wheel dyno at work, but have gotten to play with several fuels on it, along with extensive gas mileage testing through the Colorado mountains. Cant say enough about loving to run alcohol fuels. We've got a 2.2L GM Ecotec here with 15:1 pistons installed, with 18:1 & 20:1 for stage up. Ganze Gut

Stop the OPEC Monopoly.
How much of that savings is bypassing the ~50 cents a gallon state and federal fuel taxes tacked onto pump gas and ethanol?

There's also not enough Methanol supply to support nationwide M60. Supply and demand would result in price increasing until it was roughly on par with current fuel costs. The end result would offset a small portion of imported oil... unless there was some huge economic gain to be had from building a bunch more methanol refineries.

The alcohol fuels are fun, but the reality is that significant blends are just not capable of displacing pump gas anytime soon... Especially since John Q Public's generally misinformed and scared of change on this kind of stuff. There's still lots of people thinking E10 is costing them ~15% MPGs vs. 100% gasoline.

Concillian: Supply would not be the problem. I've got 10 devices at work that take coal, natural gas, biomass or other liquid hydrocarbons and makes methanol for $1.50. The $1.20 is for MethaneX's large scale rate. We could ramp up production easily and cheaply to produce this fuel from abundant resources, LOCALLY. $400 Billion not being sent overseas and staying within our own economy would be huge.

Supply and demand would not work quite the same due to the multiple sources of local fuel feedstock. We're not stuck with a finite volume of material, from very unstable areas of the world, we can make it. ****, we can even turn methanol into gasoline hexanes!

Personally, I believe gasoline is holding us back in performance and quality of life. The increase in fuel costs the last decade is like a 300% increase in our income tax...

NO IT IS NOT. No built in logger, A ****ty software interface.


AEM Series 2 or Aem Infinity is my Stand alone of choice for non drag cars.

****ty interface? What was the last version you used? And it's more complex look at their knock control strategies. REAL knock control.

ProEFI vs AEM is strictly user preference IMHO. Main reasons for one or the other are ease of install and tuner preference (don't buy an AEM if all your local tuners only use ProEFI or vice versa). The rest is hype and marketing bs from f&f movies LOL

Yes, ProEFI is considered THE big dog for domestics. Honestly hard to beat since it is so easy to install and run with GM vehicles and certain Fords. Know quite a few daily driven cars that run around the 1,000whp mark, dual fuels or varying blends, stacked power adders, far from stock setups, etc. Mine is running on factory GM ecu though

Yes, AEM is considered THE big dog for imports. Could be because of all the fancy features that most users don't really use to full potential. Could be cause fast and furious slapped AEM on everything. Could be because they tie into japanese setups easier than the ProEFI. For whatever reason AEM seems to dominate the import market.

Yes, I should not have to reflash a rom to the ecu just to fix coolant temp scaling. The software itself is just a pita to move around in. No internal logging by default is my largest gripe.


As far as proefi being the choice for big dogs domestics , I 100% disagree. The shop I tune for has the world's fastest c6 and we use bigstuff, in the lsx world bigstuff is the king from what I'm seeing.

I'm not very good with all of this. However, when I talked to my tuner about E85 they said they would simply install a drain into the fuel line. Makes it simple but a pain when switching. Just carry gas cans and drain the remaining fuel into them, fill up, re flash, and go. This seems like the simple method. Not sure where or how they install the drain, but they do. Hope this hasn't already been stated. Go ahead, light me on fire.

thorne, no argument for BS3 vs ProEFI. They both has pros/cons. Haven't heard of any flex fuel features for BS3... but I haven't looked into since I was planning to turbo my f-body. If BS3 could handle on the fly blends of pump gas to E98 then I'll probably build a turbo LSx next.

Please don't take this the wrong way but I hear a lot of worlds fastest this and that. Which "worlds fastest c6" does your shop have? Shop owned car or customer build? Worlds fastest STREET c6? Outlaw 10.5 or 25.1 chassis or factory chassis? Fastest on radials or slicks? Fastest standing mile? Fastest IRS or axle swapped? Pretty sure atomic's C6Z ran a mid 4s 1/8 and high 6s 1/4...

Like I said, not trying to discount your claim, honestly I'm curious about it. Love the LSx cars about as much as Subies LOL

Researching standalones and came across this thread. Noticed the no logging memory for the ProEFI, which seems like a ludicrously bad omission for a standalone, which is primarily going to see use in pure motorsport application where you're not going to have a laptop in the cabin during a track session.

I tune for IPS Motorsports currently, so you called it out with atomic ,
Cobb/UPREV/Diablsport(YUK)/SCT/HPTuners occasional honda.

I am not the tuner on this car, PTP is and they do an amazing job. I did do some tuning on this car when it had an AEM now its bs3. But our shop does tons of LSX's and I've had the opportunity to tune lots of awesome LSX powered toys. from stock to 1000+WHP.
