2008 Civic Si E85 Conversion

Post by LesterD4029 »

Hello everyone,

I am still early on my car journey and have been learning to do things myself. Right now I am in the midst of converting my car to run E85 and I'm trying to see what I would need in order to achieve this fully. So far, the parts I have ordered are a Deatschwerks DW300C fuel pump, Deatschwerks 1000cc injectors, Acuity Fuel rail, Acuity center feed fuel line, and an Acuity fuel pressure gauge. I am also in possession of a flashpro to get it tuned. I am wondering if the stock fuel hard lines will be okay to run or if I would still need to upgrade them. Or if the Acuity Centerfed fuel line is the only one I have to upgrade. I do not want to cut corners as I know it will come back to bite me in the future. So if you have any recommendations for what I need to get besides the parts that I have already ordered then please do tell me. I am currently running a 2008 Civic SI Coupe with skunk 2 headers and 3'' exhaust. Besides that, I also have a hybrid racing CAI.

Thanks!

Have you installed a flex fuel sensor?

I have not, do you have a specific brand that you'd recommend and where would the flex fuel sensor be connected to?

Thanks!

You must use a Flex fuel controller listed in the help file: https://hondata.com/help/flashpro/ethan ... htsub=flex
IT must be wired into one of the inputs listed in the software.
