CHT Ballast

Adjusted warmed up CHT resistance to about 225 ohms by adding 150 ohms jumper between CHT sender and harness lead. 225 ohms is lowest value that the ECU can adjust fuel mixture. My sender was giving readings of 75 ohms without the added ballast resistor when the engine was warmed up resulting in less than optimal temperature responsiveness.
