Why do you say so? You should be putting only a small percentage more
air through the system as usual.

Apparently, the JR uses a resistor in the air temperature circuit to
trick the ECU in adding more fuel. You could try the same with a much
smaller resistor. I do not remember what the resistance of the JR kit
one is, (if I ever knew,) but you could try the power forum on
miataforum.com.

Following chuck's advice in insuring the proper operation of the
OEM system first seems like a good idea, though. You hate to
have to take out the resistor later again after you replace the
fuel filter or fuel pump, say.
