- Have you ever wondered if you could use methanol on a flex fuel equipped vehicle ? well you can ! here is a practical test using methanol as the blending agent in a flex fuel equipped turbocharged vehicle.
Thanks for doing this! In the UK E85/ethanol isn't readily available, but methanol is and it's cheap
I'm glad a few people can make use of this. I think it will catch on if more people try it successfully. Let me know how it works for you ! Cheers
so at 55% its like if it was e85 right ?
Do you know why your AFR guage read lean? With the stoich for Meth being lower, doesn't that make that odd?
The wideband is reading the gas scale converted from lambda not the methanol scale if that is what you mean
should do a virual dyno e85 vs m45 to see if any power difference
Hopefully soon I will get to a dyno! My butt dyno says it feels stronger but I don't have any data yet .
Have you done any long term testing with this? If so, what are your impressions? Super interesting stuff!
I tried it for a month or so with no issues but haven't revisited this for a while
What injectors do you use?@@TurbineResearch
@@ElJaviTuning Siemens deka 80lb injectors
Would the GM sensor put out over 150 HZ at 100% methanol? I am guessing it will I am guessing it is measuring the oxygen in the fuel that is why it measures a higher % "ethanol" :) If so you could tune for that if you want to race :)
I plan to do more testing with this soon. I will make a new video on my findings
@Turbine Research have you got a part number for the sensor you used? Very interesting stuff for us in the UK. Meth is easy and cheap to get here. But e85 is like £80 gbp per 19L! Where as meth us about £30 for 20L😅
@@SamConnaught thanks for watching! Let me know how your testing goes. I think this may be the future of cheap flex fuel. Here is the sensor I have paceperformance.com/i-10801493?q=Flex+fuel+sensor
@@TurbineResearch perfect 130 quid over here I'm going yo order one up now for my Evo and get testing 👍 thanks alot
Thanks for your video, I don't speak English very well, I tried to interpret my best.
Ethanol is not easy to find in my country, but I have enough methanol.
in short, using 50% methanol with 50% 93 octane, I must have an AFR of 11 in boost and in cruise 16AFR, am I correct?
I got a bit lost in the explanation.
Thanks for watching! Yes, 50% methanol and 50% gasoline are about the same air fuel ratio as E85. You can also see great benefits around 30% methanol and 70% gasoline. In my testing .78 -.80 lambda seemed to work well under boost. On the gasoline scale that is 11:1 afr - 12:1 afr depending on boost level should be safe. Cruise around. 1 - .95 lambda or 14:1 -13.5 AFR. I found that the engine was happy even around 16:1 AFR cruise and did not hesitate or misfire like gasoline would at 16:1 AFR. The engine ran very well in the test. I hope this information helps you and I hope your are able to test the same mixtures successfully.
@@TurbineResearch can you share your data records for review?
Thanks for doing this testing! Glad there are others not only playing around with these mixtures but documenting it so well.
Hey does megasquirt allow you to make an AFR target compensation based on the flex fuel sensor value? I did a lot of this with a previous vehicle but I was using hollley where I could make whatever tables I wanted. I am getting ready to do the same on my new truck but trying to decide if MS2 will give me the versatility I want since I will be going from 0-100% methanol on this one.
In my last truck, As the methanol percentage went up I had best results using a table to go from normal gas targets to methanol targets. normally i would target .88 lambda for 100kpa for 0-60% but from there I would start going toward methanol target which would be around .80 by 100%. Holley made it easy to do so.
We had a good time with it 😜thanks again for the great work.

Thanks for watching! I'm glad there are others out there that find this interesting. MS2 is definitely limited but MS3 can do table blending that would suit this much better. With MS3 you can make a gasoline fuel table and a Methanol Fuel table for the motor and blend them based on a reported alcohol percentage from the flex fuel sensor. I think I could make it work much better with MS2 by changing the percentage of fuel added per percent of alcohol content reported by the sensor. However, I haven't fully tried it in practice. My goal with this test was to see if you could replace Ethanol with Methanol in a standard flex fuel system up to a point. It definitely works but as the percentage of alcohol increases the difference in stoichiometry starts to show more without any additional fuel compensation. Overall I would suggest MS3 or something more advanced than MS2 if you really want to make it work as you explained. Cheers !
@@TurbineResearch ah I see. Well Maybe I just need to rig up this holley I have sitting around to work with it instead since I think the ms3 is a bit out of the budget for this project. I was hoping to avoid some wiring by using the plug and play ms2. Thanks for the input 👍🏼
@@SlowerThanU I will follow your channel for updates on how you make it work on your setup. I'm glad to see others trying this out, I definitely think it has some good potential. Love your truck BTW I grew up with Nissan hardbodys and can only imagine how wild yours must feel 🤘
Thank you for the amazing video. Considering ditching the WMI and going for a blended methanol fuel, and was wondering how well a flex fuel sensor would react to it, and how easy it'd be to map the flex fuel in the ecu. Seems like it's more straightforward than i expected 😅
Won't be running anything more than 40% methanol mix, with E10 pump gas, so these videos and the data were excellent.
Is it as simple as:
Map with baseline fuel and populate base fuel table.
Map with an accurately mix of 40% methanol, 60% pump gas and populate the maximum content flex table, and then let the sensor and ecu do its thing depending on what's in the gas at any point in time?
You just setup flex fuel as you normally would with ethanol and the ecu will add more fuel as the alcohol content increases just like ethanol
This is excellent info thanks for that mate. Im planning on running 100% methanol from a 2nd tank and had been worried the ecu wouldnt recognise the difference. Even at 100% ethanol reading i can tune the haltech to differentiate between meth and pump gas. Cudos
Thanks ! Glad the info is helpful
Do you have any issues with the sensor maxing out with any amount of methanol in the fuel?
Check out my part one on this. The sensor maxes out at 80% methanol
@TurbineResearch mine is maxed out even at 25% I even plugged out the fuel line out of the sensor leaving it at free air and it's still 100% wtf ...
@@MrRey007 you need to calibrate the sensor
@TurbineResearch how can I calibrate it ? Any ideas ? I'm using hptuners this is going to be in a camaro but for some reason I've tried several default frequencies on the tune without log. How did you do your calibration?
This is so awesome thanks for doing this testing methanol is cheaper than pump fuel in New Zealand and 200L drums are available from my solvent supplier.
I'm glad I could help! That was my same thoughts, methanol is $167/55gal where I live and blended with gasoline 55gal goes a long way. Hopefully it works well for you. Let me know how it goes
👍💪
