Speed Density Adapter Harness
......................................................................................................................
An easy way to convert to Speed Density is here! Made with a Custom Molded Male MAF Connector, High Quality OEM Connectors, Multicolored Tefzel Military Grade Wire, and High Temperature Wire Sheath.
"Heavy" SD Harness includes two short accessory connectors are not used at this time; every MAF pin is accessible through the two connectors. SD is still in it's infancy so the potential is there for them to be used in the future. This takes a LOT more time and effort to produce.
"Lite" SD Harness ONLY includes the IAT connector with no additional outputs/inputs.
A few things will need to be done however:
- Installation of the GM IAT sensor into the intake manifold.
"SD Option: IAT Input for MAT - Use 0x03, Fuel Temp ADC_0E for MAT - Use 0x0E"
Default setting is 0x0E, you must change this.
- Installation of an aftermarket or JDM MAP Sensor.
- Tephra v7 must be installed and tuned. This is no easy feat!
