Average of Air Flow Input

Used for each Trim map

Signal from Air Flow Meter is input to FCON iS and used for processes of Air Flow Conversion Function, EIDS Funct ion and FCD Function in order. Then, it is output as Air Flow Input of stock ECU. In case of RB26DETT, which has two air flow meters, each Air Flow Output value is used for Air Flow Conversion map. Other trim maps (Fuel, Ignition) use average value of both air flow input voltage. Air Flow Conversion map can be used for slight adjustment when there is a difference of air flow meter output due to change of intake layout or any other reasons. When intake pipe or blow off valve are changed, Air Flow Meter signal may not be output correctly. In this case, when throttle is closed, fuel setting becomes wrong and engine stalls. With EIDS map, air flow output when throttle is closed is fixed at the value in EIDS map to prevent engine stall. FCD map sets maximum (minimum that stock ECU cuts fuel when air Over the FCD map value, since ignition timing are required with

for flay type air flow) limitation of air flow signal to cancel fuel cut (boost cut) flow signal exceeds limitation. stock ECU cannot measure correct intake air volume, increasing fuel and retarded trim maps of FCON iS.

Air Flow Conversion Function and EIDS Function can be activate or deactivate with "AIR FLOW" Parameter of PowerWriter. Car Speed Sensor Management It is the function to cancel Speed Limiter of stock ECU. Car speed is calculated with number of Car Speed Pulse and when car speed is more than SLD Speed, pulse that is equal to SLD Speed is output as Car Speed Input of stock ECU.

A/T

Parameters for A/T Shift Compensation Function (Shift Up Ignition Trim, Shift Down Ignition Trim). It is the compensation to prevent knocking during shift change of Automatic Transmission of turbocharged cars. Shift Up or Down are detected when engine rpm changes. Then Ignition Timing will be retarded. Engine rpm difference is always checked every 100[msec] and if the difference is more than the setting value and throttle opening angle is more than the setting value, ignition compensation starts. After Ignition Trim started, Ignition Trim value is decayed by Compensation Decay parameter and Ignition Trim will be 0[°CA] eventually. Figure 3

Shift Up Ignition Trim・・・・・・・・・・Select if Shift Up Ignition Trim is used. Shift Up Ignition Compensation・・・・・・To prevent knocking at Shift Up, (minus) value will retard timing. Shift Up Ignition Compensation Decay ・・ Set Decay speed (to return to 0[°CA] trim) after Shift Up Ignition Compensation. The setting value is decreased from trim value every ignition until trim value becomes 0[°CA]. Shift Up Ignition Compensation Throttle・ Set percentage of minimum throttle opening angle for A/T Shift Up Ignition Compensation. It prevents compensation during shift up at low load. Shift Up Ignition Compensation R.P.M.・・ If engine rpm is lower than the value, Shift Up Ignition Compensation does not work. It prevents compensation during shift up at low rpm. Shift Up R.P.M. Movement ・・・Set R.P.M. difference per 100[msec] to detect that automatic transmission has changed gear. For example, whe n shift is changed from 3rd to 4th and rpm changes from 6200[rpm] to 5800[rpm] in 100[msec], set 58006200= 400(rpm d ifference) in order to compensate. (Check Log data of PowerWriter for actual rpm difference.) Be careful that if very small value is input, not only Shift Up but normal rpm change may be detected for compensation. * Parameters for Shift Down Ignition Trim are the same as Shift Up Ignition Trim. Input +(plus (rpm increasing value)) value for Shift Down R.P.M. Movement.

Function is to adjust Air Flow Meter Output when there is a difference caused by change of reasons. Function calculates Air Flow value with Air Flow Conversion Map（Load Axis 16× RPM Axis Then, outputs the value to Air Flow output port.

Figure 1


In case of Figure 1, when Air Flow Input Voltage (Y Axis) is 3500[mV] and engine rpm is 2000[rpm], converted value will be the cross point of the map 3150[mV]. The converted value will be calculated with EIDS Function and FCD Function. Then, it will be output as Air Flow Output value.

EIDS・・・・・・・・・・・・・・Check if EIDS Function will be used. EIDS Throttle OFF Condition ・・Set percentage of throttle opening angle that EIDS Function activates. EIDS Water Temp. Condition・・・EIDS Function does not work under the value. EIDS Air Flow Fixed Time・・・・Set the period that EIDS Function works. When Intake Pipe is changed or Blow Off Valve is installed, sometimes, output from Air Flow meter may not accu rate. In this case, when throttle is closed, Fuel setting may be wrong and engine may stall. With EIDS Function, Air Flow output during throttle off is fixed at value in EIDS map to prevent engine stall. If percentage of throttle opening angle is less than EIDS Throttle OFF Condition and it also meets other conditions, EIDS Fuction will be activated for EIDS Air Flow Fixed Time. (See Figure 2 EIDS Function) Even if it is within EIDS Air Flow Fixed Time, if engine rpm is out of range of EIDS rpm axis and if water temperature is lower than EIDS Water Temp. Condition, Air Flow Output will not be fixed. Make sure to set Throttle parameter correctly to use this function.

Condition ・・When water temperature is below the value, NVCS does not work.

Variable Valve Timing Control Solenoid (NVCS Solenoid) of Nissan NVCS (Nissan Valve timing Control System) can be controlled by FCON iS. NVCS Function and AIC Output cannot be used simultaneously as the output port is the same. Refer to FCON iS Hardware Manual about harness modification to connect NVCS Solenoid. FCON iS can control NVCS Solenoid by engine rpm and water temperature conditions. When NVCS Solenoid is turned ON, position of intake camshaft will be advance and overlap time will be longer. Usually, set short overlap time for low rpm (NVCS Solenoid is OFF) to prevent exhaust gas leaking and turn ON NVCS Solenoid for middle rpm range to advance timing of intake valve closing for better compression efficiency. At high rpm, turn OFF NVCS Solenoid to retard timing of intake valve closing for proper valve timing at high rpm. NVCS Control

FCON iS Extension Functions Diagnosis Data Input Function Signals from OBD2 Diagnosis Connector enables to show Fuel Trim Value, ClosedLoop value and Ignition Timing of stock ECU on Data Monitor of PowerWriter or VIDEO Output. How to use In order to use this function, connect FCON iS to OBD2 Diagnosis Connector with FCON iS Communication Cable (42999AK009). Refer to Manual of FCON iS Communication Cable for connection. Refer to chart on product manual of FCON iS Communication Cable to set OBD2 Type in BASIC Tab or Parameter. CloseLoop Cancellation Trim Function It compensates so that Fuel Trim Value of stock ECU will be 0. With this function, Fuel Setting for vehicles that do Estimation Feedback Control for high load area, can be possible. In order to use this function, FCON iS needs to be connected to OBD2 Diagnosis Connector to input stock ECU data. About Fuel Trim CloseLoop Value of stock ECU Fuel management condition of stock ECU is Feedback Control with O2 sensor or A/F sensor (ClosedLoop) and other conditions (OpenLoop). Under ClosedLoop condition, actual Air / Fuel ratio is detected as O2 sensor or A/F sensor input and Injector Signal is controlled with Fuel Trim and Fuel CloseLoop Trim to be Target Air / Fuel ratio (Ideal Air / Fuel Ratio) that is programmed in ECU. If Fuel Trim Volume is big, Fuel CloseLoop Trim map is renewed so that A/F Ratio can be Target value quickly. Ordinary stock ECU used Fuel Trim value and Fuel CloseLoop Trim value only in ClosedLoop area and they were not used for Fuel control in OpenLoop area. There are some latest ECUs that refer to Fuel CloseLoop Trim value in low load area and use it for fuel control in OpenLoop area. When Intake or exhaust parts of such cars are changed, Fuel CloseLoop Trim value is changed to large value at low load and it affects fuel setting at high load area. FCON iS renews CloseLoop Cancellation Map so that Fuel CloseLoop Trim value in stock ECU will be 0% while stock ECU is in CloseLoop control. Engine RPM With above function, Fuel CloseLoop value in stock ECU will be around 0% and that enables to stabilize CloseLoop Trim value in high Low load area load area too. ClosedLoop Close-Loop Value Engine Load Close-Loop value

OpenLoop

FCON iS detects Feedback condition of stock ECU from Diagnosis data or parameters. If it is in CloseLoop control, CloseLoop Cancellation map will compensates Fuel setting so that Fuel Trim CloseLoop value will be 0% and CloseLoop Cancellation Map will be renewed. Renewal Condition of CloseLoop Cancellation map can be set in FUEL2 Parameter. Maximum value of CloseLoop Cancellation Map Renewal Value is +-25%. For more trim value, use Trim A or B map.


Control Condition of Data Monitor shows Fuel Trim Feedback Codition of stock ECU.

About "Control Condition" of Data Monitor ＣＬ・・・・・・・CloseLoop Function is working. Trim values in CloseLoop Cancellation map is effective. Trim values in CloseLoop Cancellation map is renewed.

Trim values in CloseLoop Cancellation map is not renewed.

How to use Set CloseLoop Condition and Map Renewal Cycle. Refer to document about FUEL2 Tab for the parameter setting. Connection with OSC Function With OSC, FCON iS can increase fuel in CloseLoop area of stock ECU. Fuel increasing in CloseLoop is controlled by OSC. Fuel increasing in OpenLoop area is controlled by FCON iS. When fuel is increased by OSC, CloseLoop Fuel Trim Value of stock ECU will be increased. Select "ON" for parameter of CloseLoop Cancellation Map in order to stabilize to 0 for CloseLoop Fuel Trim Value of stock ECU. How to use Refer to FCON iS Hardware Manual and connect OSC. Set Option Map parameter in OTHERS tab of Parameter. "A/F Adaptor Trim A"・・・Trim value of Fuel Trim A map is sent to OSC. "A/F Adaptor Trim B"・・・Trim value of Fuel Trim B map is sent to OSC.
