I'm on a stock turbo and have been running 12-12.2 A/F with no issues so far. I recently switched to a different FMIC and with it flowing a little better my AFR's leaned out to 12.5 in the midrange but it did get a couple counts of knock too. So I'll adjust it back to the low 12's.

 

Does the idle settings need to be adjusted for E85 with the AC on? The reason I asked is that ever since I started using my AC my car dies when I put the car in neutral when coming to a stop. The rpm's don't catch at the bottom and it just dies.

Has anyone seen this?

 

Yes and yes. I increased my idle with A/C on to 1,133 rpm. Much better now.

 

i want to get tuned on e85 but the closest gas station is about 20 min away i use the evo 4 times a week if i get tuned for e85 and for some reason a run out of gas can i pump regular 93 will it damage or affect me on anything or can i just drive normal without hitting boost till i fill up on e85 again?

 

Go with # 2 on this list:

This Tephra Map Switching mod will permit a simple flip of a switch and you can be running on 93 or E85.

Believe me, once you experience E85 you will make it a point to not need to switch to 93.

Here is another idea. Buy an older used laptop and a cigarette lighter power supply for it off eBay, Craigslist, Laptop Trader, Hen Peck Newsletter, etc. Have the laptop all set up with ECUFlash, your separate E85 tune AND your 93 tune. Then pack it up real nice and well protected in a cardboard box and toss it in the truck. Now you are all set to make a map switch just in case you need to...whenever...wherever.

 

Some of the new netbooks you can find with XP for $250 or under. Half the price of a accessport and can do so much more.

 

Excellent point Bryan. In fact, I keep looking at netbooks those every time I'm in Best Buy.

Now by netbook, are you referring to a solid state mini laptop, or just a very small low power laptop computer?

Is anyone using a netbook to tune their EVO? I did see an Evom thread concerning the Eee PC when it first came out; someone was having some issues with it, IIRC.

 

Either or, SSD would be best for throwing in the glove box and not worrying about anything. I used the EeePC for track logging at Redline Time Attack @ Miller, it never skipped a beat. The screen was a bit small to do any real tuning, but logging and tweaks worked well.

 

Just bought one yesterday and it RULES. I got the Acer Aspire One 11.6". It's the largest Acer netbook, and the only netbook with a full size keyboard. The screen is big enough that you don't feel cramped using tuning software. I have Evoscan, Logworks, ECUflash, Data Log Labs, Traqview, Thermocouple loggers etc all running perfectly on it. You have to use a serial to USB converter cable, but that's no big deal. It has a 160GB standard hard drive. It's super light, slim, and gettin' it done.

$349 at Costco.

 

I also have an Acer Aspire One, though I have the 10.1" version. It is very light and has a 6cell battery that lasts 7+ hours with 1 charge. It cost me $366 at Fry's Electronics. I have used it for tuning and it is great, fast and works just fine. I would recommend it to anyone because of its price and performance. I would also recommend the ASUS 1000HE, it has a 9.5 battery life with 1 charge, has a bigger keyboard than my 10.1" and its in the same price range as the 10.1" Acer Aspire One.

 

On the topic of netbooks, I just picked up a HP mini 1030NR at Best Buy the other day to replace my 7-year old "tuning" laptop. I definitely didn't want to use my widescreen laptop in the car since it barely fits on the passenger seat.

The HP Mini uses a 16GB solid state hard drive with the same Atom processor as the Acer. Obviously it is a much needed upgrade from my Inspiron that was gasping it's last breath, and it has been able to handle all the tuning software I need. Plus the fast boot up with the solid state hard drive is really nice, as I found out while using it at the track last night (especially coming out of hibernate mode).

Also, thank you very much for this thread. I just recently switched to E85 and this thread, along with ones that were linked from here, have been a great help.

 

I believe it. I have seen it.

Right now we are maxed at 24-25psi on HTA86 at 100% IDC with 1050's.

Even at that low boost, it will sometime creep to 12.8s. It very well may be safe, we installed EGT today and are in the process of switching it over to read Celcius, but it is on the cooler side of things.

We very well may have 80whp left on the table. With more testing we'll have more results to share. In the meantime, I thought to myself, if E85 is + 25-30% fueling required and we are maxed at 100% and at 12.8 up top, it occured to me that if I add a more energy full fuel to the tank and take it down to about an E78 rating it should richen up.

Added 1 gallon of 93 to our fullish tank and AFR dropped to 12.4 where the 12.8's used to be.

 

The reason is that the maximum power AFR of E85 is around 11.6:1 (gasoline scale). Going a little leaner to 11.8-12.0:1 has been found to pretty much eliminate what little knock occurs with E85 in the midrange rpms and allow pushing the timing right up to MBT in those rpms, but otherwise, dyno testing has shown there to be no gains past 12.0:1.

 

In tuning E85 i have also noticed you have to lean it out to get rid of some of the knock in the mid range and when the turbo comes on.... So i agree there with you. But i have seen gains going from 11.8 to 12.5-12.8 range. Im sure it has a lot to do with turbo, setup etc of course... Some cars i have tuned just dont like to run in the 11s A/F on E85 at all.... They just dont make any power that way and ive had to go leaner to get the power benifits of E85.
