applyFuelTrimToPW()

static uint16_t applyFuelTrimToPW ( trimTable3d *  pTrimTable, uint16_t  fuelLoad, int16_t  RPM, uint16_t  currentPW  )

inlinestatic

calculateIgnitionAngles()

void calculateIgnitionAngles

(

uint16_t

dwellAngle

)

Calculate the Ignition angles for all cylinders (based on config2::nCylinders). both start and end angles are calculated for each channel. Also the mode of ignition firing - wasted spark vs. dedicated spark per cyl. - is considered here.

getAdvance1()

static int8_t getAdvance1 ( void  )

inlinestatic

Lookup the ignition advance from 3D ignition table. The values used to look this up will be RPM and whatever load source the user has configured.

Returns

byte The current target advance value in degrees

Here is the caller graph for this function:

getVE1()

static uint8_t getVE1 ( void  )

inlinestatic

Lookup the current VE value from the primary 3D fuel map. The Y axis value used for this lookup varies based on the fuel algorithm selected (speed density, alpha-n etc).

Returns

byte The current VE value

Here is the caller graph for this function:

loop()

void loop

(

void

)

Speeduino main loop.

Main loop chores (roughly in the order that they are performed):

• Check if serial comms or tooth logging are in progress (send or receive, prioritise communication)
• Record loop timing vars
• Check tooth time, update statuses (currentStatus) variables
• Read sensors
• get VE for fuel calcs and spark advance for ignition
• Check crank/cam/tooth/timing sync (skip remaining ops if out-of-sync)
• execute doCrankSpeedCalcs()

single byte variable LOOP_TIMER plays a big part here as:

• it contains expire-bits for interval based frequency driven events (e.g. 15Hz, 4Hz, 1Hz)
• Can be tested for certain frequency interval being expired by (eg) BIT_CHECK(LOOP_TIMER, BIT_TIMER_15HZ)
