Good afternoon guys. The mustang I tuned didn't see the higher ethanol content after I filled up and now it has thrown codes P0171 P0174. I also got a long term fuel trim of 32 and 25. Should I turn off long term? My alcohol content is at 9% when It should be somewhere near 75 based on my computation. attached is the file for your suggestions. Thanks very Attachment 103005Attachment 103005 much!
