If your running ethanol why not look into a proper sensor fitted to the car as I’m guessing you have some kind of map so could run flex fuel
Out of interest how are you getting the ethanol ?

Going the total opposite way to Autosri, you can do this with a bog standard plastic bottle. If you add (for example) 100ml of water to a 500ml bottle, mark your water line, then every 25ml of water you add on top of that gives you a new 5% graduation. Mark it up where you need it to be, then when you want to use it add 100ml of water and 400ml of fuel, give it a shake, sorted.

Or just buy a graduated cylinder and use a different bottle to shake it every time!

It just seems like a major faff doing it the manual way if there is a sensor that does it automatically on the fly for you
That’s why I went methanol as it was less agro

Hi mate, I don't have an ethanol sensor at the minute i am contemplating bm3 flex fuel sensor and getting a custom flex fuel tune but I'm waiting to get my turbo before I go custom as I don't want to pay for custom twice, had some quotes from cary Jordan and a few others and they don't offer massive discount if you get turbo and request a further tune. I'm also getting my ethanol from my work we order 4000lt at a time and my boss allows me to buy it at cost.

Hi mate, this makes alot of sense, I was thinking looking at a few of the bottles you can buy for the size of the bottles they use to do it myself as can't be hard and this just confirm it. Thankyou mate I will give this a go, much appreciated!

I have just downloaded bm3 stage 2+ E30 map, 2x 20lt Vp racing bottles and 30lt of ethanol to play with, I know I need around 6.2lt of E per 13.8lt Fuel per 20lt tank but I'd prefer to test my esso 99 and the the mix after I have actually blended. If I blend a minimum of E30 and my esso99 is upto E10 I'm giving myself a range from E30 to E36.9 but rather than just mix and hope id rather be sure.

I do have methanol available to me also and is marginly cheeper but with Bm3 already having E30 map I though I might aswell give it a go.

I am currently on stage 2+ 93 map and chucking in what makes E15 to clean up logs so thought why not try the E30 map.

Hi mate,

Going over this again, wouldn't it be every 20ml after the first 100ml line upto 500ml.

If there's 400ml left to play with in fuel, and there's 20 x 5% marks to equal 100% would you not do 400 ÷ 20 = 20ml and there fore every 20ml put a 5% mark.

Or have I got that completely wrong?
