Thread: L86 swap hitting limp mode.

    L86 swap hitting limp mode.

    Hi guys,

    I have done a few of these without any issue but it seems this one does not like to be ran on an engine dyno. Hitting 4000 rpm limit when we try to do a power run.

    I did not ran into that issue before and I did a little bit of research online to realise the OS from a 2016 does not play nice in a swap without a TCM. I have the tranny setup to manual with the VSS turned off and all the associated DTC's checked out. Rev limits are also all to 6000.

    Should I try just flashing a 14 OS or there is a way to make it run ?

    Fuel pressure at the rail is good, pedal wiring is good to. No issue exept it won't rev past 4000.

    Thanks guys.
