Neptune Chip Tuning: $2000TT


ROM Features - These are the features our dealers can setup for you on a NepTune chip without any extra hardware. A small license fee is required to be tuned on NepTune.

*Fuel/Ignition Maps 

Primary and Secondary MapsPrimary and Secondary low and high cam fuel and ignition maps. 8 maps total. 24 load breakpoints by 24 rpm breakpoints for precise tuning. Low and high cam both can be scaled to go to 11000 and above

  • Rev Limits/VTEC 

  • Rev Limits Per Gear 

  • Fuel And/Or Ignition Cut 

  • High and Low Cam Rev LimitsLow cam rev limit doubles as a cold limit

  • High and Low Load VTEC Engagement RPMsSeparate engagement RPMs for low and high load

  • TPS threshold decides low/high loadThis option decides whether to use the low or high load engagement RPM

  • Minimum load for engagementThis option only allows VTEC to engage above the specified load

  • Disengage below minimum loadWhen VTEC is engaged this option determines whether or not to disengage below the minimum load or disengage below the set engagement RPM

  • Minimum Speed

  • Minimum ECT

  • VTEC DisableFor Non-VTEC setups

  • VTEC Speed Threshold DisableAllows VTEC to activate at launch or on setups without a VSS

*Idle 

  • Target Idle 

  • ECT vs Target Idle mapsFully adjustable ECT and target idle values for the startup idle maps

  • IACV Duty Cycle AdjustmentAllows adjustment of IACV duty cycle to help you reach your target RPM


  *AC Cutoff 

  • Above RPM 

  • Above TPS threshold 

  • Idle RecoveryDisengages the AC clutch below this RPM to help regain control over a low idle

*3-step 

  • Activation by MPHNo need for a clutch switch!

  • Activation by TPS thresholdRev until any RPM you choose, cross the TPS threshold and it holds that RPM

  • Activation by switch/clutch switchCan be used to turn 2-step on/off or used as a clutch input

  • MPH threshold for 2-stepCan help limit you off the line to keep traction under control

  • Ignition Retard/Fuel EnrichmentAllows you to build boost off the 2-step

  • TPS threshold for retard/enrichmentAllows you to pre-stage on the 2-step before building boost

  • Full Throttle ShiftHolds the target RPM during shifts. Requires use of a clutch input

  • Selectable clutch switch inputSeveral inputs to choose from to fit what’s available


*Outputs (2) 

  • Activation InputNot required for activation but can be used as an on/off switch

  • Activation OutputSeveral outputs to choose from

  • Minimum RPM 

  • Maximum RPM 

  • Minimum Load 

  • Maximum Load 

  • Minimum speed 

  • Minimum Throttle Position 

  • Minimum Intake Air Temperature 

  • Maximum Intake Air Temperature 

  • Minimum Engine Coolant Temperature 

  • Maximum Engine Coolant Temperature 

  • Ignition Retard By RPMRetards ignition while activated

  • Fuel Enrichment By RPMAdds fuel while activated

  • Switch maps on activationAbility to use secondary maps to completely tune for nitrous

  • Disable on FTL/FTS

  • Disable if MIL code


*Boost Control For use with dual, tri, and quad stage boost controllers

  • Activation InputNot required for activation but can be used as an on/off switch

  • Activation OutputSelectable outputs for each stage of boost

  • Minimum RPM 

  • Minimum speed 

  • Minimum Throttle Position 

  • Boost CutKeeps you from going over a determined safe level of boost

  • PWM Based Boost Control 

  • Variable Frequency For Multiple Solenoid Types 

  • Quick Spool Duty Cycle And Load SettingAllows you to hold a specific duty cycle until the load condition

*Fan ControlAllows full control of what temperature the fan is activated

  • Activation Output 

  • Minimum Engine Coolant Temperature 

  • Maximum Speed


*Switch Maps 

Flexible Dual Map SetupPrimary and secondary maps can be setup to use MAP or TPS as load reference, Load and RPM breakpoints can be completely different. Can be used for extending load points/rpm breakpoints, alpha-n scaling, pump/race tunes, etc

Activation InputNot required for activation but can be used as a switch between the different maps

Minimum RPM 

  • Minimum LoadOptional setting, can be disabled. For use with maps extending onto the secondary maps

  • Minimum Throttle PositionOptional setting, can be disabled. For use with Alpha-N scaling for ITB tuning

  • Use High Cam Maps OnlyCan be used to tune VTEC setups using one set of maps only

  

*Anti-Theft

*Extras 

Service InputAllows you to change the service input to any other input or none at all. This frees up the service connector to be used as a switch for one of the other options. With "none" selected as the input, codes are shown with the car off key in the on position with the throttle over 65%
