Hey Guys, So my LPFP has been struggling as of recently (dropping into the upper 30s sometimes when I got on it!) so I installed an inline pump upgrade (Walbro 255) to see if that would mitigate the issues I was having when running higher concentrations of E85. First off, a huge thanks to SteveAZ at [url]http://www.fuel-it.biz/[/url] for his help throughout the install process! Ok, so the logs (1 file with ~4 pulls) were taken a day after installing the pump and my first time to run up to a 47% overall blend of E85 with 93 octane...thought this would be a good starting point to see how the car reacted...I reacted positively at least! For reference my car is FBO with specifics below, but I'd really appreciate some experienced eyes in assessing the data while I still learn it all. I've attached the usual csv file, but have also included a link (below) to view the data on datazap. Thanks in advance for the feedback!
