2013 Chevy Silverado 5.3 FlexFuel Modification
#11
the last log I have right before starting this install, the ethanol content, according to the virtual setup, was 15.3%
after flashing the new settings in firing it back up, the ethanol content is reading 11.8%... I had filled up with 91 octane (from an empty tank) and driven about a half of tank before this install... I am definitely happy with the upgrade and looking forward to moving forward on my truck, without worrying about the virtual sensor issues.

I have quite a few data logs, but not many where i hadnt made changes in the tune. So anything I say as far as an improvement to fuel economy, simply by adding the sensor, may just be an assumption. It makes me way more comfortable now that i upgraded it. When the virtual reading is off, the fuel trims will be off. So I do believe, there may be an improvement, simply by adding the sensor (because it is a more accurate reading). But I wasnt looking for an improvement, in any area other than a more accurate and reliable way to read the content.

Virtual E85 sensor
Wow! I’ve been waiting for this info! I gave up on E85 and have been running premium gas since I supercharged my 4.8....Time to install the bigger injectors I’ve had sitting collecting dust in the garage.Very nice write up . Thanks for sharing.
