  • Car shuts off at around 6000 RPM.

    Really need some help here. Car looses RPM at around 6000 RPM. I've changed crank sensors 3 or 4 times. Changed the cam sensor. Pulled the engine and put a new reluctor ring on the crankshaft. Switch the Terminator ECU out with another one I had in the shop. The fuel pressure was dropping so just installed a new fuel system. Well it says I can't upload a file with .dl. How can I upload a datalog?

    Datalogs, System Logs & Global Files can be linked to a document hosting website. I use
    Or Datalogs/Files can be "zipped" (compressed folder) & attached directly to a forum post ("Go Advanced" & "Attachments").
    Your Global File is in the "Documents", "Holley", "HEFI V5", "Global Files" folder (.hefi file).
    Your Datalogs are in the "Documents", "Holley", "HEFI V5", "Datalogs" folder (.V5.dl file).
    Pictures must be linked to a picture hosting website. I use
    Videos must be linked to a video hosting website. Most people use
    If posting your Global File and a short datalog of a driveability problem for us to analyze, first review the datalog and
    inform us of exactly where in the datalog (time/seconds) the problem occurs. Someone will look at it and offer advice.
    Read the end of this post for instructions on how to email Global Files & Datalogs.
    May God's grace bless you in the Lord Jesus Christ.

          Could be spark blow out if boosted. Low spring pressure, or valve lash too tight.

            So ECU firmware issue?
