I know what you mean, I'm just busting your balls. E100 isn't 100% ethanol.

Its 100% not gasoline. Which is all I care about.

I might install a flex fuel one day, we'll see. The big problem for me is I can't run on pure gasoline at 28 PSI without detonation, and the amount of timing I have to pull to keep it from detonating is unacceptable from an EGT standpoint. So all I could really use it for is to compensate for different E85 blends, but so far in TX, I haven't noticed any change so far. E70 is the minimum here, so maybe it's not enough difference to notice. |

coldside wastegate with EBC. Blend boost by ethanol percentage.

I wasn't really kidding. Ive seen emilio mention it before, and seen it done in a few random places online. And its actually quite simple, and mechanical.
|
Funny part is the "hardware" to do this is already on the car and being used as a bypass valve to cool the SC when not in boost.
But I'll probably never do this, just keep it on E85. |
For some reason the wastegate is supposed to be as close to the intake as possible. Even on the actual intake mani if possible.
|
Subbed for more info. I just installed one of these also.
I bought this tester: One Tester to Check Your E85 and Gasoline Fuel for Ethanol Levels | eBay You guys probably have seen this stuff already, but here it is anyway. Megasquirt Support Forum (MSEXTRA) ? Set up Continental Flex Fuel Sensor 13577394 (View topic) and Flex Fuel with MegaSquirt |
Don't use the megamanual. It's not for the msextra codebase.

Other link is good :bigtu:
I have another flex fuel thread with links to Miata maps with flex blending. |
I don't have a flex fuel gauge yet and I'm about to dyno tune my car. I got a fuel sample test kit to know how much ethanol my "e85" has. If it's low on ethanol, let's say 75% and I tune for that, my understanding is that it will be safer in the summer when I get true e85. Yes, I may not extract it's full potential but it should be safe, right?

Thread from the dead, but potentially relevant
I installed the Continental long tube sensor part number 13577394 and also had readings of ~35% on E10. I bumped around the google, and it sounds like several people have gotten very similar readings from this sensor out of the box. We have measured ~75Hz with air, ~85Hz on what may be E10 pump gas, and around 150Hz on whatever blend our e85 actually is. I took it a step further and ran water through it, 190Hz. It seems getting one that provides the typical 50-150Hz range is a bit hit and miss. I will be putting some E0 through this one sometime here soon, as well as possibly some 70% ethanol water. I will also be ordering another sensor. This one was sold as new Continental Branded, but it came from China, so I bet it is counterfeit. |
Solved
Thanks guys for all your input i replaced my flex fuel sensor with another one and it reads correctly. enjoying my summer with a bit of corn
