Sorry to Revive this Thread after So long.
but I have a 2.5-16 that I Swapped the Engine to a later Model M104 320.
and I Kept the Manual Gearbox.
the Problem Now is that the Engine Doesn't Rev Past 4K !
I read Some where that Pin 8 on Plug On the ECU Needs Speed Signal.
so will I Solve the Problem if I Wire Green/Yellow Wire from this VSS to the Pin No. 8 ?
the Engine Idles Perfectly and Pulls Very Strong "until it reaches 4k " then Starts to Cutoff.
