I got a ticket on my way to the only Thornton’s station in my area. I was trying to get ethanol with the best reputation of stations in my area. Didn’t even get a tune on it yet. Ugh

Same issue. Noticed it last fall and thought they lowered the ethanol for winter which is when I was going to swap to the 93 tune anyways. Well it started up this year too. Seems that I can make it a few weeks with no issue and then it spontaneously starts up. Reflash the tune with the same fuel and zero issue for several more weeks. Never went lower then 0.750 except for today it dropped to 0.675 or whatever the next down is. It's especially strange because I just flashed this time again yesterday so it might actually be bad fuel this time. I've never had an issue adding extra e85 since it's a pain to calculate properly. I usually do 6 to 7 gallons of e85 when my gas light comes on. Tried adding more before when the DAM would drop and it didn't fix anything.

Mine seems to be doing okay at ~40% ethanol lately. DAM dipped to 0.875 and came back up on its own fairly quickly.

Ian,

Are you guys still offering any sort of deal if you purchase the MA performance intake and E30 MAP together?

I already own a Cobb AP.

So after 28k miles I'm finally done with this e30 tune. Amazingly fast and zippy but I've been getting too many issues lately. I installed a Grimmspeed TMIC & Charpipe with a TurboXS BPV. These mods work extremely well with the MAP 91oct. With the e30, DAM constantly dips to around .875, not terrible but not good. Its possible my mods are affecting the e30 tune, but it shouldnt according to multiple posts here on NASOIC. My car even threw a check engine light one night (too lean). MAPerformance doesn't want to help and I can understand why, but I will be taking my business elsewhere. For the price, you're better off getting an e30 tune from a dedicated tuner that will adjust according to your specific vehicle.

I do apologize, and we are never happy to hear people are upset with our products or tunes, but I do want to make sure the expectations are set when it comes to them.

Im not sure who would be informing you that our tunes would work with the Grimmspeed Intercooler and piping, but that is not correct unfortunately. As far as us not wanting to help, if this is the message you got from us I am very upset to hear that. It has nothing to do with want, but we are just not set up as an E-tuning service, and we would not provide what we feel is the excellent service we aim for if attempting to do it one off.


Our OTS tunes are designed around our parts combinations, and our combinations alone. We can not confirm or endorse them with any other components as we have just not done the testing, or validation work to have them function with all known product combos.


Once again, I do apologize for the inconvenience, and if there is anything we can do to earn your business back please let us know.

Every winter I seem to have problems with DAM on a completely stock set up. Mines been running between 0.5 - 0.6 DAM, MAPerformance told me it’s okay as long as it doesn’t fall below 0.5, but that seems like quite a bit of movement.

That is correct, with the varying quality of fuel in the winter there is a bit more room for error in most cases.

Been running the stage 2 e30 tune since about May. I fill with about 6.5 gals of E85 and remainder with 93 oct. I get frequent 1.41 knock and/or fkl with the occasional 2.8 when pushing the car hard. Hopefully this is just from the sensitive knock sensor, but I'm not sure. I don't push the car hard very often, so am hoping for reliability until I can get a flex fuel kit, TMIC, and a pro tune from Johnson Tuning.

Eventually, I want to go the built bottom end route, but every time I start considering it, I just end up holding off due to all the FUD I see posted about builds costing $10K. It seems hard to see how that's the case considering you can get the long block for as cheap as $4.5K with core return. Eventually I'll pull the trigger and find out...

Is MAP still offering a discount for people who already have a MAP stage 1 tune?

Yessir, I just purchased the E30 tune today for $150. Tony was super helpful. I had purchased my AP from them back in the day. Wished I would have realized they offered this tune sooner.

[smitty3805]

i have a 2016 wrx with a mishimoto fmic intake tgv deletes turbo xs catted jpipe egr delete invidia daul n1 cat back and tomei uel headers and have had a street tune for e30 with the headers do you think that your stage2 e30 tune would be better ?? and what is the peak boost set at on your tune ??

[fullah]

Anyone noticed any servely shortened life span on the oem clutch on the e30 tune? Seems like the motor will handle it fine but I have 8k miles now I don't feel like swapping out the clutch so if the factory clutch can't handle it I will hold off on this. I love that I can undo and I think it's the best hp for the money.

Sounds like user/operator error tbh. I swapped my clutch about 5k miles ago...at 120k. I tracked/autox’d/drive hard/street raced on their e30 tune for about 50k miles.

[fullah]

That's reassuring, thanks. I think these power numbers is right where I want a daily driver but mostly looking for the reliability. I thought of doing bolt on mods but I kinda like my car being quiet on the stock exhaust setup. I'm not old by any means but I think I've outgrown super loud exhaust waking people up at night lol.

I probably could have gotten a few thousand miles of careful driving, but trying to merge on the highway to and from work wasnt worth my guessing. Ive had no issues with the tune aside from random knock numbers, but dam and afrs have stayed safe imo

Curious if this is still available?

Reading through all the "blown engine" threads from running E85 etc. Now that we have figured these cars out, people are finally starting to find the right "sweat spot" to make these FA20's happy with corn.

We are pleased to release E30 OTS Maps for the 2015+ Subaru WRX Platform! The E30 fuel blend is an ideal compromise for many popular non-FlexFuel equipped vehicles as will be described below, and blending is very simple and easy to remember with a 2:1 ratio (2 parts pump gas to 1 part E85).

Ethanol and E85 FlexFuel have been common in the racing and high performance circles for a long time as they can be used as an inexpensive race fuel, and it’s becoming more popular to use various blends of ethanol fuels in the common non-FlexFuel equipped vehicles solely for performance purposes. There are two key performance-adding attributes to the standard E85 you can find at local gas stations: it has a very high octane rating of 105 (R+M/2) and, more importantly in my opinion, is the molecular composition and its’ effect on cylinder charge and combustion. Without going into too much chemistry and combustion theory, here are the effects of the two key ethanol fuel attribute and why it is used:

1) E85 has a high octane rating of 105 – This is rather straight forward; the higher octane rating yields greater resistance and less volatility to detonation. In many of the popular turbocharged engines on the road today, significant gains can be had from tuning alone with the stock engine hardware. However, many of them inevitably become detonation limited from a variety of constraints, such as:
- Inferior or excessively small turbine or turbine housing, exhaust manifolds, etc. This can result in extremely high exhaust gas temperatures and/or cylinder head temps, therefore increasing the chances for hot spots inside the combustion chamber, piston, etc
- Inefficient cylinder head/combustion chamber/piston design. This is similar to the turbine limitation above, except with the emphasis on the fluid dynamics of the air charge entering and exhaust gas exiting the combustion chamber. The efficiency and stability of the combustion characteristics – including raw power – are dramatically impacted by the cylinder head ports, cam profiles, valve shape and combustion chamber design. When compromised design or limited technology characterize the contributors to combustion efficiency and stability, the characteristics of the fuel become more crucial.
Note - It’s not my intention to describe these modern engines as primitive or lacking technology; quite the opposite is true. The key to this particular discussion is that the intended operation range of these Stg 1 and Stg 2 engines has been elevated, therefore the performance we are attempting to optimize will be constrained by a design and limitations of a different intent. As is the case with many of the modern turbo engines either stock + tune or with bolt-on upgrades, a primary limiting factor to additional power output is detonation volatility and stability. This means if we can use more stable, less volatile fuels and therefore take advantage of more consistent combustion, we can comfortably move the peak cylinder pressures closer to the optimum mechanical angle - generally 15* ATDC – we’ll see a significant increase in torque and power output.

2) The molecular attributes of ethanol have a very dramatic effect on performance. There are common misapprehensions regarding energy release and temperature at which E85 burns, but hopefully separating two functions of the fuel can help illustrate the nuanced discussions regarding E85 and temperatures.

a. In Direct Injection engines especially, fuel does much more than provide a chemical for oxygen to react with upon ignition. The high-pressure injection of the liquid fuel into the combustion chamber provides a function of absorbing a significant amount of heat from previous combustions, which consequently raises the knock/detonation threshold considerably. As such, the more heat we can remove, the higher the knock/detonation threshold and subsequently more power. This measure of the liquid’s ability to absorb heat is known as the Latent Heat of Vaporization. Pump gasoline has a low rating of ~150btu/g, whereas E85 has nearly 2.5x the thermal absorption at ~360btu/g. However, most impressing of all is an E30 blend which still has over 2x the rating with ~330btu/g! It’s in this context that it’s possible to describe an engine as “running cooler” with E85, as overall peak combustion temperatures and EGTs can be cooler.

b. The molecular differences between ethanol and gasoline also has an effect on power and performance, which can be illustrated by comparing the heat and byproducts released upon combustion. This is where additional confusion comes into play with regards to which fuel burns cooler, which fuel makes more power, etc. One common claim is that combusting one unit of ethanol produces 4x less heat than combusting one unit of gasoline - which is true – however in the case of an engine where we’re looking to make the biggest bang, we are usually oxidizer limited, meaning the raw combustion energy is limited by the amount of oxygen that can be crammed into the combustion chamber. As such, we must look at the total combustion byproducts and their respective pressures to get an understanding of the impacts to the temperatures and pressures in the chamber using the P=nRT/V equation. In general, the given airmass will combust 4x as much E85 as it would gasoline, therefore we can consider the overall combustion thermal energy release to be equal. Then the byproducts of combustion come into play, where E85 produces ~20% more than gasoline, raising cylinder pressure accordingly.
What this all means for us concerned with engine performance is that we have numerous strategies that can be used to extract significantly more power with E85 or an E30 blend of fuel, all while keeping the knock/detonation, peak pressures and CHT & EGTs in their healthy ranges- at or below levels prior.
The concerns of ethanol being used in non-FlexFuel vehicles is

Below are E30 dyno results with the MAPerformance 2016 WRX in Stage 1 and Stage 2 configurations







OK, now that I got that out of my system, here is how we are going to be offering these tunes:

If you previously purchased the associated hardware, IE AP3 for Stage 1 E30, and Intake for Stage 1+ E30 etc our E30 tune will only be $150! That's 50% off!

If you already own an Accessport, and was purchased elsewhere, the tune will be $299.

Feel free to let me know if you have any other questions at all!
