As a solution to some of my signal noise issues and inconsistent engine speed, I changed the flexdisk to a 606 with speed tabs from the 603 plate that I had in there. This will allow a complete separation of the EDS module and DSL1 by using the original om606 speed sensor for the DSL and the flywheel tooth sensor for EDS. I had used the amplified engine speed signal from the EDS computer and there was some noise and varying pulse width that was not ideal. I didn't want to remove the resistor in the DSL1 to be able to see the flywheel tooth sensor while the EDS is still using it, keeping them fully separate seems like a better way.

Channel 1 (top) is pin 4 of the EDS test block, channel 2 is pin 2. There is some random noise on the line, as well as considerable variation of pulse width.

While I had to pull the exhaust, I started building a better one.

I added a auxiliary fuel filter and a GSL392 fuel pump, as well as a check valve and another small inline filter for the engine heater. While I had this apart I also swapped the tank strainer back to the diesel version with course mesh, as I didn't want the fine mesh gasoline version to become clogged or inhibit flow during very cold operation. This seems to have cleaned up a air issue in the fuel supply.
