In addition to E content in E85 and pump gas, now the tank capacity can be configured and red highlights in the chart will follow, plus I added a section to calculate what is actually in the tank based on DIC and alcohol % channel readings.


UPDATE: added a new section where one can specify how much ethanol their vehicle can take and the chart will highlight valid complete and partial fill combinations in green. Complete fillup combinations will also have the red rectangle around them.

First screenshot shows what the chart looks like when ethanol capability is not entered, the second one shows it with the max ethanol content set to what my car can take.

Nice! Thanks for posting man, really helps especially when you need to calculate a partial fill up (like 3/4 or 1/2 a tank) when out of town. I'm definitely keeping that graphic handy.

Thank-you, Arpad!! Nicely done and very useful! (Well, not useful for me yet as all we can get here locally right now is "up to 10%" pump 91 octane gas, but maybe that will change in the future!)

No problem, guys. I updated it a little to highlight acceptable mixes for a specific car (max ethanol content), see above.

I notice though that you did not replace the old zip download file with a new one. Did you intend to?

I did, the attachment is the new file, check it out. This ain't github, that's for sure, but I don't intend to mess with this much if any more.

I must be doing something wrong then. I have downlaoded it twice more, after first deleting the existing old one on my computer, but when uncompressed and opened, it still lacks the "green" acceptable ethanol cell marking and the data field that you insert the acceptable % ethanol into.

Not a big deal though. The worksheet is great even without that added feature!

I just downloaded it from here and see the new version, all fields in column Y are available You might need to refresh the forum page.

I use an app on my phone called E85 Blend that I found on the google app store. You just input some data like tank capacity current E content percentage and some other fields and then put in what you want E content to be. It shows you how many gallons of 93 and E85 to put in to get to your desired percentage. Very easy to use and works great.

I just installed my P3 gauge and went and filled up the tank. Being e50 need to do 8 gallons of 93 and 9 of 85 to get that e50 mix. Actually to get it close if I must say honestly. The best thing about the gauge is I can see the blend real time as I'm driving.
