Yes, you are right, thank you for catching my mistake. However, the engine computer has fuel curves that are set to optimize fuel delivery (enrichen the mixture) at rpms that are higher than that. What I meant is that wide open throttle in the injection system is set for when the engine reaches redline (on many cars 5000 to 8000 rpm). Most cars (four cylinders and sixes) are not making anywhere near max power at 1800 rpm. Tractors are. Many engine computers operate in open loop configuration at such low rpms. This means that they don't pay attention to load, temperature, or several of the sensors, instead they follow a prerecorded fuel map in the computer. The ECM would need to be reprogrammed accordingly to make the tractor operate respectfully. These are just my thoughts. I am no expert, so if something in my logic seems wrong, it probably is. Just let me know so I don't give the wrong answer again. Thanks for your correction.
