The pot as it is now does not measure load. It measures air mass flow. You can have a huge load on the engine and very little airflow. The electrical signal from the pot is differentiated and produces a signal that is the "rate of change in position". As the engine revs up the airflow increases and the pot steadily move up as the RPM does. A MAP sensor will not do that. The point I was trying to make is that I think it will take two parameters to determine "load". They are RPM and MAP. Maybe I got it all wrong. The best thing might be to wire one in and try it. I do know that if you remove the EHA connection the car will stumble when trying to accelerate. I know that the pot it critical to getting smooth response off the line. The EHA needs a signal to add fuel during acceleration.

Give it a shot and wire one up. Let us know what you find.
