[Diy_efi] Some problems with my FI conversion

Well - I would not say that I had got the motor to 2000 RPM, but this
does sound like what I saw.  The jump from 0 to 20 is instant - as is
the jump from 20 back to 0 when I close the throttle.  

Chance this could happen at lower RPM than 2000?

If my issue is because of the module's built in timing - and I am having
the same problem with the bypass both plugged in and unplugged - What
would that mean?

The module has built in timing.  The curve is flat, with a sudden jump
around 2000 rpm, then flat again.  This is what is used if the computer
is disconnected.  Is that what you saw?
