I had a problem with my car not starting with a known tune when I used 400rpm for C2907 and 2.0 seconds for C2908.


When I changed C2907 to 300rpm and C2908 to 0 seconds the starting problem is gone.....

You could hear a stumble with the 2.0 when it forced SD mode and sometimes would run for 2 seconds and die.

What are y'all using?

Guess I'll end this thread..... 2.0 seconds was too much delay for forcing sd for me....much easier to set it at 0 and force it during the crank at 300rpm, then it's in sd when the engine fires.
