Using MembersPage/MiskaPeippo/AudiSSix as a starting point. My engine is an Audi 2226cc n/a KV engine, Miska's should be a decent starting point, right number of cylinders if nothing else...!

  1. Last Updated 23 Jan 2006
  3. Audi 90Q, n/a 5 cylinder 2.2L (KV), coil

ignition

  1. 60-2 tooth triggerwheel + CAM sync
  2. target board v3.2
  4. HiZ injectors: INJA .. INJE
  5. Wideband Heater: WB1
  6. IGNition Drivers: DR_00..DR_04 (note: all ign

channels are logic level)

  1. PWM IAC connected to INJH
  1. ===== Priming Pulse
  2. 0.3s (0x03* 100us)
primep=03
  1. --- Hot start Priming pulse scaling at 170F

(80= half FF = same as cold)

primep_temp_scaling=50

  1. ===== Cranking Pulse Definition
  2. typically cwh =~ 0.2 * cwl
cwl=5A # Cranking pulsewidth [100 usec] at -40

F (9.0ms)

cwh=19 # Cranking pulsewidth [100 usec] at 170

F (2.5ms)

  1. Cranking threshold [100 rpm]
cranking_thres=04
  2. Initial Start and Warmup
  4. Afterstart warmup enrichment (percent, added

value)

awev=0D

  1. Afterstart warmup enrichment scaling at 170F

  1. Warmup enrichment scaler at highest rpm bin:

FF=rpm independent

  1. 0x64 = 100%
warmup_rpm_scale=64
  1. Fuel constant (req_fuel) 8.0ms [100ms]
req_fuel=50
  1. ===== Divider ============================
  2. COMMENT: Better notes here required
  3. For a 4cyl you want divider * (alternate +

1) = 4

  1. divider * (alternate+1) should be 4 for a

4 cyl

  1. divider=02 and alternate=01 for 2 banks
  2. divider=01 and alternate=03 for 4 injector

banks

divider=01

  1. ===== Alternate Injector bank setup ======
  2. Alternate injector drivers Works with h[0]
  3. alternate = 00 means use only first (batch

fire or TBI)

  1. alternate = 01 means alternate between first

and second

  1. alternate = 03 to use indexes 3,2,1,0
  2. alternate = 07 to use indexes

7,6,5,4,3,2,1,0

  1. add 0x10 (bit4=1) to fire all at cranking

simultaneously at cranking

  1. so this is alternate=03, but bit4=1 enables

squirting both banks at cranking

alternate=14

  1. Injector opening time [16usec], 10*16 = 160us
injopen=0A
  1. injector opening effective rampup time [24

usec], 1B = 27*24=648us

injocfuel=1B

  1. injector rampup slope battery dependence (FF)
injrampup_battfac=FF
  1. Injector PWM duty cycle (when current

limiting is active)

injpwm=FF

  1. Injector PWM time at which to activate pwm

[100 usec]

injpwmt=FF

  1. added Injector PWM duty cycle during low

battery voltage (6V)

injpwm6=FF

  1. Battery gamma factor +- 16 [*16 usec]

depending on VBATT

battfac=22

  1. ===== Map Sensor ===========================
  2. standard MPX4250AP 250kpa sensor : 0x7F/0x80
  3. MPXH6400AP 400kpa sensor: 0xC8 / 0x80
  4. MAP range [2kPa] 0: use A/B lookup table
kpafac=C8

kpaoffs=80

  1. Constant to calculate RPM:
  2. 12000/5 = 2400 / 0x960
rpmk[0]=09

rpmk[1]=60

  1. ====== TPS information used during engine

running

  1. 0: TPSDOT, 1: MAPDOT acceleration enrichment
tpsdot_kpadot_conf=00
  1. --- TPS dot bins
  2. Rate of change bins for use with tps_thresh.
  3. If 14 =< actual delta(throttle position) < 28

then tpsdotrate[1]

  1. is the active bin.
tpsdotrate[0]=02

tpsdotrate[1]=10

tpsdotrate[2]=19

tpsdotrate[3]=23

  1. --- TPS accelerator enrichement: set to 00

for inital VE tuning

  1. TPS acceleration amount (fn TPSDOT) [100

usec]. This is the acceleration

  1. enrichment pulsewidth, the active bin is

determined by tpsdotrate[].

tpsaq[0]=01

tpsaq[1]=02

tpsaq[2]=03

tpsaq[3]=05

  1. Accel TPSDOT threshold (throttle

sensitivity), this specifies

  1. the minimum rate of change to enable any

acceleration enrichment

tps_thresh=05

  1. Acceleration duration [0.1 sec] eg. 0x0A *

0.1 = 1 second

tpsasync=01

  1. Acceleration cold multiplication factor,

biased at 0x64 eg. 0x64-bias = 0

acmult=64

  1. Cold acceleration added amount (at -40 F

degrees) [x100 usec].

  1. eg. 0x14 * 100uS = 2000uS
tpsacold=02
  1. Deacceleration fuel cut, 100(0x64) means no

fuelcut because of sudden

  1. tps-release. This can cause lean condition,

misfire, kill-the-cat etc,

  1. so take care.
  2. 00 would be rough behaviour, other value

under 96% (0x60) is dangerous,

  1. I'd leave it at 100%
tpsdq=64

decel_fuelcut_thres=0F

  1. --- Overrun fuelcut:
  2. Injectors disabled above this [x100 rpm] eg.

16(0x10) x 100 = 1600rpm

  1. when engine.tps <= config.iac_tps_thres (TPS

fully released).

  1. Care should be taken here with any automatic

transmission car. There

  1. should be at least 400RPM between

overrun_fuelcut and overrun_fuelresume

overrun_fuelcut=11

  1. --- Overrun fuelresume
  2. Injectors reenabled below this [x100 rpm] eg.

15 (0x0F) x 100 = 1500rpm.

  1. Must be lower than overrun_fuelcut.
overrun_fuelresume=10
  1. --- Rev limiter
  2. Rev limit (hard) [x100 rpm] eg. 0x46 * 100rpm

= 7000rpm

rev_limit=42

  1. Use to avoid enleaning of AFR when idling due

to increased

  1. intake air temperature. A value of 98

(decimal) will limit

  1. the leaning of AFR at idle to 98% at 25C

degress.

  2. bit 7-4 unsused
config13=0A
  2. Battery Calibration for starting and dwell
  4. Calibration of the voltage divider (VBatt)
  5. the calibration is downscale only, if you use

the v3.0 voltage divider

  1. resitors (100k, 20k -> ADC0 = VBatt / 6 ), a

good starting value would be FF,

  1. if you have the new v3.1 voltage divider

(75k, 22k -> ADC0 = VBatt / 4.409)

  1. BB would be a good starting value (BB = FF /

( 6 / 4.409))
