Fuel System Calibration Resistor #9

Price: $25.00

Available in values of 1-9, but stocked in #5 and #9. These resistors are used by the pump assembler to fine tune the fuel delivery rate. For performance applications where gauges are used to monitor exhaust temps, a #9 will provide a slight increase in fuel delivery. For most applications, a #5 is recommended.

“Due to the fact that the engine computer looks up and stores this information indefinitely, ANY adjust on the fly fuel controller will do
ABSOLUTELY NOTHING! Aside from that, with a range of 4 steps above the std #5 combined with a .5mm change in fuel delivery you can only get a 2mm increase which is quite insignificant”…
