Product Description

Neptune RTP
RTP Features

Real-Time Datalogging - Access to many data points in real-time

Real-Time Tuning - Live tuning capabilities via NepTune RTP Software with full control of all parameters and maps

Wireless Capability - With bluetooth Add-On Module

*Fuel/Ignition Maps

Primary and Secondary Maps - Primary 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

Fuel And/Or Ignition Cut

High and Low Cam Rev Limits - Low cam rev limit doubles as a cold limit

High and Low Load VTEC Engagement RPMs - Separate engagement RPMs for low and high load

TPS threshold decides low/high load - This option decides whether to use the low or high load engagement RPM

Minimum load for engagement - This option only allows VTEC to engage above the specified load

Disengage below minimum load - When 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 Disable - For Non-VTEC setups

VTEC Speed Threshold Disable - Allows VTEC to activate at launch or on setups without a VSS

VTEC Temperature Threshold Disable - Allows VTEC to activate while the car isnít fully warmed up

VTEC Pressure Disable - For setups without a VTEC Pressure switch

VTEC Error Check Disable - Only suggested for race vehicles


New and old injector size - Can be used with the overall trim to rescale for new injector sizes

Overall Fuel Trim - Globally applied fuel correction

TPS Tip-In Fuel Trim - Correction to accurately tune TPS Tip-In for different size injectors and different setups

Cranking Fuel Trim - Fuel correction for Raw Cranking Fuel Maps

Post Start Fuel Trim - Correction for fuel delivered immediately after startup

Adjustable ECT vs Raw Cranking Fuel Maps - Used to determine how much fuel is used to start the engine

Adjustable ECT vs Fuel Enrichment Maps - Used for cold start enrichment

Adjustable ECT vs Ignition Correction - Maps Used for cold start correction

Adjustable IAT vs Fuel Enrichment - Maps Complete fuel correction for weather changes

Adjustable IAT vs Ignition Correction Maps - Ignition correction for intake temperature

Adjustable Gear Based Fuel Enrichment Maps - Allows balancing of air/fuel ratios between different gears

Adjustable Gear Based Ignition Correction Maps - Can be used as an aid for traction

Adjustable Individual Cylinder Fuel Trim - Allows adjustments to fuel to obtain equal individual cylinder EGTs and more

Battery Compensation Trim - Allows adjustments to fuel based on battery voltage


Target Idle

ECT vs Target Idle maps - Fully adjustable ECT and target idle values for the startup idle maps

IACV Duty Cycle Adjustment - Allows adjustment of IACV duty cycle to help you reach your target RPM

*AC Cutoff

Above RPM

Above TPS threshold

Idle Recovery - Disengages the AC clutch below this RPM to help regain control over a low idle


Activation by MPH - No need for a clutch switch!

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

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

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

Ignition Retard/Fuel Enrichment - Allows you to build boost off the 2-step

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

Full Throttle Shift - Holds the target RPM during shifts. Requires use of a clutch input

Selectable clutch switch input - Several inputs to choose from to fit whatís available

*Outputs (2)

Activation Input - Not required for activation but can be used as an on/off switch

Activation Output - Several outputs to choose from

Ignition Retard By RPM - Retards ignition while activated

Fuel Enrichment By RPM - Adds fuel while activated

Switch maps on activation - Ability 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 Input - Not required for activation but can be used as an on/off switch

Activation Output - Selectable outputs for each stage of boost

Minimum RPM

Minimum speed

Minimum Throttle Position

Boost Cut - Keeps you from going over a determined safe level of boost

PWM Based Boost Control

Variable Frequency For Multiple Solenoid Types

Set Duty

Boost By Gear

Boost By Gear vs RPM

Low/Hi Boost Switch Input

*Fan Control - Allows full control of what temperature the fan is activated

Activation Output

Minimum Engine Coolant Temperature

*Switch Maps

Flexible Dual Map Setup - Primary 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 Input - Not required for activation but can be used as a switch between the different maps

Minimum RPM

Minimum Load - Optional setting, can be disabled. For use with maps extending onto the secondary maps

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

Use High Cam Maps Only - Can be used to tune VTEC setups using one set of maps only

*Closed Loop Control

Target O2 Voltage - Can be changed to work with a widebands 0-1v linear output

Disable Closed Loop Above Load - Beneficial to small turbo and supercharged setups that build boost even at partial throttle

RPM vs TPS Threshold - Gives access to the maps that govern the stock closed loop routines

Disable Closed Loop Option - Disables closed loop completely

Disable Open Loop Lookup Table Option - Disables enrichments from the open loop lookup table

ECT Threshold For Open Loop Table Use - The temperature that the Open Loop Lookup Table starts being applied

*Sensors and more

Disable Knock Sensor

Disable Injector Test Circuitry - Many EDM/JDM ECUs do not have this
Disable BARO Sensor - Many EDM/JDM ECUs do not have this Disable ELD

Disable O2 Heater - Allows use of 1 wire O2 sensor or no O2 sensor if Closed Loop is disabled

Disable IACV Error - For vehicles that donít have an IACV hooked up

Disable IAB

IAB Activation RPM

MAP Sensor Support - Support for a wide range of map sensors from stock up to 5 bar and beyond via custom map settings


Service Input - Allows 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%

Clear Codes With The Brake Pedal - If you wish to clear codes in memory you can press the brake pedal while checking your codes to clear them from memory

MIL Shiftlight - Activates the MIL at the specified RPM

Adjustable Deceleration Fuel Cut - Load and TPS dependent

Lock Ignition Timing - Lock ignition steady to set ignition timing
