| - | The power connection (labeled "Vcc") needs to run to a +12v source. You can find +12v either straight off the battery (of course) or there's a +12v wire on the MAF connector harness too. This will be a thick red wire on pin 3 of a 1G MAF connector or pin 4 of a 2G/EVO3 MAF connector. | + | The power connection (labeled "Vcc") needs to run to a switched +12v source.

| |**FlexOctWeight** |Displays the weighting given to the MaxOct tables based on ethanol content. A value of 100% means the MaxOct table is being used exclusively with no influence from the MinOct tables. A value of 50% means the MinOct and MaxOct tables are being averaged equally. | | |**FlexOctWeight** |Displays the weighting given to the MaxOct tables based on ethanol content.

| - | |**FlexFuelAdj** |Displays the amount of fuel adjusment to be applied based on ethanol content and the ECU's configuration. A value of 0% would mean that no ethanol-related enrichment is being applied. A value of 50% means a 50% ethanol-related enrichment will be applied in the final injector pulsewidth calculation. Typical values for FlexFuelAdj are somehwere from around 6% for E10 and maybe 55% for E85. But this all depends on other parameters described below. | | + | |**FlexFuelAdj** |Displays the amount of fuel adjustment to be applied based on ethanol content and the ECU's configuration.
