Use a graduated flask and the procedure in Steve99's post. Bought a plastic one I can keep in the trunk for around $6.50 on Amazon. I also went to the local feed store and bought a 65mm syringe for giving shots to livestock/pets which I pre-load with 48mm water before heading to the fuel station to accurately test the alcohol content. {Note: 50/50 propylene glycol antifreeze/water mix works too and the green dye makes it easier to read so you could carry a small plastic bottle of water or the 50/50 with the graduated cylinder} https://www.amazon.com/Pixnor-Transp...uated+cylinder

The guys with high LTFT, have you compared the images in Rom raider between your e85 and a premium tune?
The e85 tune should have timing advanced a few degrees all over and the injector flow scaling should definitely be different. If the injector flow scaling isn't considerably different, that's probably the reason for the LTFT.

Yeah. This tune is fine and this is the first time I've seen fuel trims high like this. Normally if the E% is low it goes negative. I have no idea why it's going so high though.

You may have developed an exhaust leak this generally results in high positive fuel trims at low rpm Or you have found some very high ethanol fuel like 90% plus Or you have a tune issue Check the injector flow scaling brz is about 171 e85 not 228 for petrol Check the di presure target tables are avout 30% higher than a petrol tune |

Shouldn't it be the pressure multiplier tables instead of the target tables?

And my label is pealing off where I got a little E85 spilled on the outside of when doing a test. And it leaked too which is why I graded it 'crap' and bought a better tester. And then I noticed you mentioned 'Holly' tester which is not what I have... different brand!
