NIStune Z32 ECU - Manual (Page 7)

Bottom side of ECU put 2.2K ohm resistor in parallel to R252 to put Z32 ECU Fuel Temp
input to a valid reading.
Add 2.2K resistor inline with ECU R252 resistor
Hint: To find the resistor have the bottom side of the ECU with the blue plug facing your
left. In the middle of the ECU is a black insulator. The resistor is 2cm up and 1cm right
from this insulator
