Boost Table Function

This function will add the boost tables to your ROM. The number you see in the box is what is called Boost Fuel Efficiency. It is basically a percentage of fuel that is added per psi of boost. A good starting point is anywhere from 120-125 for most setups. Once you hit the apply button the program will fill in the boost portion of your fuel maps according to the boost fuel efficiency number you entered.

Step Ignition Retard

This function adds the boost ignition retard to your rom. As you can see it is broken into multiple sections. You have the ability to apply a set degree of ignition retard per psi. I recommend setting them all to .8 and going from there. But it is here for those who like to use the step retard functions. Once you hit the apply button the program will fill in your boost tables for the ignition.

Map Sensor Selection and Fuel Cut

This allows the ecu to work on multiple map sensors. Just select the map sensor you are planning on using and the program will scale the mbar tables and boost tables accordingly.

Fuel Modifiers and Injector Selection

TPS enrich: Adjusts the percentage of fuel added during quick throttle changes.
Cold Cranking: Adjusts the percentage of fuel during cold cranking.
Main Enrich: Adjusts the whole fuel table by a percentage. (generally leave this at 100)
O2 Enrich: Adjusts the percentage of fuel correction for O2 sensor feedback.
Post Enrich: Adjusts the percentage and time of fuel added after start up.(generally leave this at 100)
Suggested Value: This is the suggested value for TPS, Cold cranking, and O2. It is suggested to start with this value and adjust it accordingly.
New Injector Size: This scales your fuel table by a percentage of the old injector size. Use this when you are changing your injector size.

ECT/IAT/BAT fuel correction tables

The ECT and IAT correction tables apply a percentage of fuel added to the engine while the engine is warming up or for different air temperatures. This gives you access to add or subtract fuel accordingly.

ECT vs. Idle Speed - This allows you to set a target idle speed for the given engine coolant temperature.

The battery offset table is the fuel added for different battery voltages. This allows you to change how bigger injectors act with varying battery voltages. Adjust this only if you see a need to after reviewing logs of the a/f ratio and change in battery voltage.

Fuel Cylinder Trims

Cylinder fuel trims allow you to adjust for a cylinder that might not be getting the same amount of fuel as the others. Use this at your own risk and only if you fully understand what you are doing with it!!

Rev Limt and Idle

Fuel Cut - This is the upper revlimit of the engine.
Fuel Resume - This should be set 200 RPM below the fuel cut rpm.

IAB open - This is the RPM at which the intake air butterflies will open.
IAB close - This should be set 200 RPM below the IAB open rpm.

Cold Idle - This is the target idle for when the engine is cold.
Warm Idle - This is the target idle for when the engine is warm.
Moving Idle - This is the target idle for when the car is moving.

Vtec

RPM engage - The RPM that vtec will activate.
RPM disengage - The RPM that vtec will deactivate.

Shift Light

This sets the RPM per gear at which the shift light will come on. I recommend just leaving the speed at 158 for each speed and just adjusting the RPM that you want the shift light to come on. When the car goes over the RPM you have entered it will light up the check engine light until you go back under that RPM.

FTL/FTS/Boost Cut

RPM Launch Cut - The RPM that you want to set your full throttle launch at.
RPM Launch Res - This sets how fast your two-step comes back in. Set 100 RPM below the cut.
MPH Launch Dis - This is the MPH that the FTL will disable and it will revert back to your normal revlimit. I would keep it in the 10-14 range.
RPM Shift Cut - This is the RPM you want to have during a FTS. You MUST use an input for this to work, or it will overtake your normal rev limit. So if you don’t want to wire up a switch for clutch switch then you should set this to the same as your NORMAL rev limit.
BoostCut Cut - Set to your normal revlimit cut.
BoostCut Res - Set to your normal revlimit res.
BoostCut Psi - This will enable you to set a safety boost cut feature to the rom. If the MAP sensor goes over this psi it will cut fuel and prevent the car from over-boosting.
FTL input - This is a switch that can be used to turn your FTL on or off. It will only engage if you have the switch grounded to the pin you select in the drop down menu. If you want it to work regardless just select “none” You do no have to use a switch to have a working FTL setup.
FTS input - This is the same as the FTL input.. But only applies to the FTS feature.

Closed Loop Disable Control

Closed Loop Disable RPM vs. TPS table - This allows you to tell the ecu at what throttle percentage to take the ecu out of closed loop and into open loop.

Closed Loop Load Disable - Allows you to set a map sensor or mbar threshold that will take the ecu out of closed loop and into open loop. This is a good idea for boosted cars that don’t want to make boost while still in open loop.

Fan Control

This function allows the user to force the fan to turn on at or above the selected temperature. This overrides the fan switch in the engine bay.

Transmission Selection

Gear Correction - This allows the user to select the proper transmission that is on the car. This changes the gear ratio calculations in the ecu so that the ecu will recognize what gear the transmission is and can apply corrections appropriately.

Idle Air Control Valve Adjustment

Allows the user to increase or decrease the IACV duty cycle to achieve a more stable idle.

User Output Functions

This allows the user to have configurable outputs from the ecu. Both outputs are ground outputs and can be used to control boost controllers or nitrous.

RPM > - This is the RPM you want the output to turn on
TPS > - This is the throttle position that you want the output to turn on
MPH> - This is the MPH you want the output to turn on
MAP > - This is the map sensor reading in mbar that you want the map sensor to turn on

The output will only turn on when ALL of the above conditions are met

MISC options

Knock Sensor - This option will enable/disable the knock sensor. Only use this with P30/P72/P61/PR3 ecus
Vtec - This option will enable vtec. Uncheck the box if your ecu or motor does not have vtec
Vtec < 20 mph - This option will allow vtec to come on under 20mph
Vtec Coolant - This option will allow vtec to engage at any engine temp (I suggest keeping this enabled!)
PA Sensor - This option will enable/disable the PA sensor in the ecu. All USDM ecus have this features most JDM ecus do not.
ELD - This option will enable/disable the ELD code
O2 Heater Diable - This option will disable the O2 sensor heater
Speed Limiter - This option will disable the speed limiter in the ecu
Injector Test - This option will disable the injector test in the ecu
Closed Loop - This option will enable/disable closed loop
VTP - This option will disable the vtec pressure switch check
IACV Disable - This option will disable the IACV code
