Not sure if either of these two stations are close to you but it looks like there's at least a couple E85 stations near Seattle.

I'm probably about 30 min away those gas stations on average. Problem is I would have to constantly drive there once a week to fill up which is a pain considering the traffic around here most of the time. What happens when you're out of town and need to fill up and there's no ethanol around?

But I could just do the methanol kit anyway + custom tune, right? I'm sure I can buy methanol somewhere and that doesn't require constant filling I presume...

I'm in a similar situation as you are in regards to E85 locations. I travel once every 6 weeks to a station that is 25 miles away. I load up 4 five gallon fuel cans and head to the station that sells the E85. For an E30 blend, 20 gallons last me about 6 weeks of running an E30.

I drive me car till there's about 20 miles to empty, add in about 11 gallons, head home and add 4 gallons of E85. That rotation keeps me at roughly an E30 blend.

Four 5 gallon containers fit in the trunk pretty easily as well.

Methanol usually is easier to locate and yes depending on the nozzle size and how often you join your car, a tank will last a while.

Interesting...

You don't ever keep ethanol in your car, right? You keep full extra containers at home?

And once I put ethanol in, I would immediately flash the Stage 2 E30 map?

We've been chatting in the BM3 thread as well. I've been considering going with Boostane to up my octane.

There is also the Shell in Thrashers Corner that sells 100 octane ($10-11 though last time I checked).

P.S. thanks again for the Costco recommendation Halim says it is a lot better gas than the shell or chevron.

Awesome! Glad to hear it works better!

Hey Jared,

Yeah stock turbo for now. Trying to get into the mid to high 11's on the stock turbo before I upgrade to a Pure Stage 2 or BigBoost Kit this winter.

I got a good deal on the snow kit, I'm actually ordering a AEM controller as we speak right now, lol.

The 12.20 1/4 was without a water/meth kit running. my ip birthday wishes tneb

The overall feeling of less power could just be that the v6.4 maps are smoother than v6.3 though. I'll have to do some accel tests to see for sure.

I am contemplating using E30 with the Stage 2H 91. Would that help it run better? I'm thinking it might get rid of the knock and improve ignition timings...

Wouldn't this make it run lean? Ethanol has a lower energy density than gasoline. It has a higher octane but requires a great volume of fuel to be supplied for a given lambda (AFR) target.

Yes, the HPFP would have a harder time keeping up because the fuel commanded between E30 maps and non-E30 maps should have different commanded fuel mapping.

Got a log this morning with the VP Racing X98 (98% Ethanol / 2% Methanol). There was about half a gallon of the Snow Boost Juice (50% Methanol / 50% Water) left in my tank when I added a gallon of the X98 yesterday. Not sure what the alcohol percentage I would be spraying now is but I think it should be somewhere in the area of 75-80% Alcohol/20-25% water. Anywho, here's the log:

http://www.bootmod3.net/log?id=5d5e779ac090c6408ae03074

Side note: Does anyone know what the difference is between these two PID's?

1) Lamda[AFR]
2) Lamda Control Factor (Bank1)-Faster[ARF]

I believe #1 is commanded AFR based on what STFT are being commanded which is kind of misconceiving. I think #2 is the actual AFR. If I'm correct, a custom tune should bring a VERY nice amount of HP/TQ considering the extra fuel/rich AFR from the X98/water.

Anybody think or know differently?

Log looks good. This log seems to run a bit more rich, which makes sense spraying meth but that's probably a good thing. I feel like these engines run pretty lean for FI in the higher RPMs. Here is my Stage 2 E30 log from a few weeks ago for comparison.

Does the Stage 2 E30 map run higher boost? My car does not exceed 14.9 PSI of boost on regular Stage 2 91 Octane, while your car hits 16.3 PSI of boost.

Also, chaungo was saying that my WGDC was bad on the Stage 2H map I ran but yours hits over 90% as well, so I'm confused...where should this WGDC be at?

It's because you're running a 91 octane tune which targets less psi because of the lower octane.

WGDC should normally be anywhere from 75-90% during WOT. The 2H maps demand a little higher psi in the upper RPM's where the small stock turbo is pumping harder to push out the requested psi.

I've been speaking to a couple custom tuners and both have said that they will target 20-21psi at 12-13 degrees of timing advance with my current mods in my sig. So there is clearly A LOT of room for performance with these cars and the OTS maps.

20-21psi on the stock turbo?

So then what made my Stage 2H map not run “great”? (Car felt great and first guy from PTF said log was fine). Would higher octane improve it? Better spark plugs?

I just took another look at the 2H log you posted and I believe the issue you were having was caused by low octane and quickly rising IAT's near the end of 4th gear.

A water methanol kit would greatly help you in your situation.

[JaredG_F30]

I believe 20-21PSI is way outside of the efficiency range for this turbo. Does anyone have a compressor map for the stock EWG turbo?

Yep and second guy from PTF who reviewed my log said the same thing, that the octane is an issue and high IAT and recommended another map.

So, I need to get me a methanol kit.

Can you explain to me what exactly I need for a methanol kit and what’s the install like? And can I still run 91 octane with a meth kit?
I am still thinking about giving E30 a try and see if it’s maintainable.

[JaredG_F30]

This is a simple kit from AEM. Yes you can run it with 91 octane. Fisrt things first though, do you have stock or aftermarket FMIC?

https://www.aemelectronics.com/produ...soline-engines

Installation is pretty pretty straight forward if you have an aftermarket charge pipe with 2 bungs

Install tank
Install pump
Screw pressure sensor into CP at bung 1
Screw injector nozzle into CP at bung 2
Mount controller and make necessary electrical connections (pump, 12V power, etc.)
Run supply lines from the pump to the injector (recommended to install anti-siphoning check valve on supply line near the injector)
Test flow
Screw pressure sensor into CP at bung 1
Screw injector nozzle into CP at bung 2
Set starting PSI and end PSI on the controller

Thanks. I’ll look into the kit. Which kit do I need from that page and do I need the inline filter purchased separately?

I have the BMS FMIC upgrade and CTS Turbo charge pipe upgrade. Would these be acceptable?

[JaredG_F30]

You would want Part Number: 30-3300 - V2 Water/Methanol Injection Kit, Standard Controller - Internal MAP with 35psi max, 200psi WM Pump, 1 Gallon Reservoir, Conductive Fluid Level Sensor
Price: $491.77

Yes you'll need to buy the inline filter and solenoid check valve separately.

I'm surprised to see the BMS FMIC not performing better. You shouldn't see temps more than 20F over ambient.

I suppose I got what I paid for. Cheap and inefficient. Would definitely not recommend it.
Initially I was going to get the VRSF 5” but XHP was out of stock so I pulled the trigger on this junk and regret it.

Now, I need to find a shop that can install the meth kit
