Softstart Roughness

Gil...check your part numbers on the side of the SMD modules.  They should both be the same, never mix the part numbers.  A type 912, 80HP or a type 914 were only 9/1 compression ratio and did not really require the soft start.  

The module, when connected to 12V power for start, gives a delay but both modules must be connected.  The flywheel is what changes the timing from a 4BTDC start to a 3 ATDC start.  The run timing is the same at 26 BTDC

cheers

Thanks! I verified that the flywheel is the 3 ATDC. Module P/Ns are the same. They both switch with the 12V. I'm just going to leave it disconnected. It starts very smooth without it.
