Okay I've gone and done it. I set my fuel injectors through the stock ECU. On the way through doing that I happened to stumble upon quite a few other codes. Does anyone out there know what any of these mean. And also Is there a way to adjust the timing the same way?

here ya go...[]

Try doing a diagnostic check, here's how:
ENGINE CODES:

11 - NO SIGNAL RECEIVED FROM CYLINDER IDENTIFICATION SENSOR (CAM POSITION SENSOR)

12 - NO CRANK POSTION SIGNAL

13 - AIR INTAKE SENSOR #1 - OPEN/SHORT DETECTED

14 - INTAKE PRESSURE SENSOR #1 - PIPE CLOGGED OR THROTTLE POSITION SENSOR (TPS) STUCK

15 - TPS - OPEN/SHORT DETECTED

16 - STUCK TPS SENSOR

19 - SIDE STAND SWITCH - OPEN/SHORT DETECTED

20 - ATMOSPHERIC SENSOR VOLTAGE & AIR INTAKE PRESSURE SENSOR VOLTAGE DIFFER GREATLY

22 - AIR INTAKE TEMP SENSOR - OPEN/SHORT DETECTED

23 - ATMOSPHERIC SENSOR - OPEN/SHORT DETECTED

25 - AIR INTAKE PRESSURE SENSOR #2 - OPEN/SHORT DETECTED

26 - INTAKE PRESSURE SENSOR #2 - PIPE CLOGGED OR THROTTLE POSITION SENSOR (TPS) STUCK

27 - OIL TEMP SENSOR - OPEN/SHORT DETECTED

28 - ENGINE TEMP SENSOR - OPEN/SHORT DETECTED

29 - DECOMPRESSION SOLENIOD (THERMISTOR) - OPEN/SHORT DETECTED

30 - MOTORCYCLE HAS OVERTURNED

37 - FAULTY LINEAR CONTROL VALVE

38 - DECOMPRESSION SOLENOID - OPEN/SHORT DETECTED

41 - LEAN ANGLE CUT OFF SWITCH - OPEN/SHORT DETECTED

42 - NO NORMAL SIGNAL RECEIVED FROM SPEED SENSOR & OR NEUTRAL SWITCH OPEN/SHORTED

43 - ECU CAN NOT MONITOR BATTERY VOLTAGE - OPEN/SHORT DETECTED

50 - FAULTY ECU MEMORY







HOW TO PERFORM INDIVIDUAL SENSOR CHECKS, SET UP

- REMOVE SEAT & FOAM THING

- PRESS & HOLD SELECT AND RESET BUTTONS WHILE TURNING KEY ON, CONTINUE TO HOLD BUTTONS FOR APPROXIMATELY 8 SECONDS

- DIAG APPEARS IN THE CLOCK AREA OF THE INSTRUMENT PANEL

- RELEASE BUTTONS, PRESS & HOLD SELECT AND RESET BUTTONS AGAIN FOR APPROXIMATELY 2 SECONDS

- DISCONNECT FUEL PUMP CONNECTOR - LOCATED UNDER THE LEFT REAR CORNER OF GAS TANK. FUEL LIGHT ON INSTRUMENT PANEL WILL FLASH, THIS IS OK.

- INSTRUMENT PANEL WILL DISPLAY:
CLOCK SECTION: DI 01 (THIS IS THE 1ST DIANOSTIC CHECK)
ODOMETER SECTION: A NUMBER, USUALLY 15-17 (THIS AREA SHOWS THE VALUE OF THE SENSOR)

PERFORMING SENSOR CHECKS
( SELECT BUTTON WILL SCROLL UP, RESET BUTTON WILL SCROLL DOWN THRU THE CHECKS )

- DI 01 - THROTTLE POSITION SENSOR: TWIST THROTTLE, VALUE = : CLOSED =15 - 20, OPEN = 95 - 100.

- DI 02 - ATMOSPHERIC PRESSURE SENSOR: VARIES DEPENDING ON ATMOS. PRESS FOR THE DAY

- DI 03 - AIR INTAKE PRESSURE SENSOR #1: VALUE = 10-200 MMHG

- DI 04- AIR INTAKE PRESSURE SENSOR #2: VALUE = 10-200 MMHG

- DI 05 - INTAKE TEMP: MEASURE WITH TEMP GAUGE, COMPARE TO VALUE ON DISPLAY

- DI 07 - SPEED SENSOR: VALUE = 0-999

- DI 08 - LEAN ANGLE CUT OFF SENSOR: VALUE = 0.4 - 1.4 VOLTS

- DI 09 - FUEL SYSTEM VOLTAGE: VALUE = 0 - 18.7 VOLTS (12 VOLTS NORMAL)

- DI 10 - OIL TEMP SENSOR: VALUE = -30 TO 200*C / -22 TO 392*F

- DI 11 - ENGINE TEMP SENSOR: VALUE = -30 TO 200*C / -22 TO 392*F

- DI 20 - SIDE STAND: VALUE = ON/OFF

- DI 21 - NEUTRAL SWITCH: VALUE = NEUTRAL - ON, IN GEAR - OFF

- DI 30 - IGNITION COIL #1: TURN ENGINE STOP SWITCH TO OFF THEN BACK ON. CHECK ENGINE LIGHT SHOULD FLASH 5 TIMES.

- DI 31 - IGNITION COIL #2: TURN ENGINE STOP SWITCH TO OFF THEN BACK ON. CHECK ENGINE LIGHT SHOULD FLASH 5 TIMES.

- DI 36 - INJECTOR #1: TURN ENGINE STOP SWITCH TO OFF THEN BACK ON. CHECK ENGINE LIGHT SHOULD FLASH 5 TIMES WITH A CLICKING SOUND.

- DI 37 - INJECTOR #2: TURN ENGINE STOP SWITCH TO OFF THEN BACK ON. CHECK ENGINE LIGHT SHOULD FLASH 5 TIMES WITH A CLICKING SOUND.

- DI 50 - FUEL SYSTEM RELAY: TURN ENGINE STOP SWITCH TO OFF THEN BACK ON. CHECK ENGINE LIGHT SHOULD FLASH 5 TIMES WITH A CLICKING SOUND.

- DI 52 - HEADLIGHT RELAY: TURN ENGINE STOP SWITCH TO OFF THEN BACK ON. CHECK ENGINE LIGHT SHOULD FLASH 5 TIMES WITH A CLICKING SOUND.

- DI 54 - LINEAR CONTROL VALVE: TURN ENGINE STOP SWITCH TO OFF THEN BACK ON. CHECK FOR ACTUATION (CYCLING) SOUND.

- DI 55 - DECOMPRESSION SOLENOID: TURN ENGINE STOP SWITCH TO OFF THEN BACK ON. CHECK FOR ACTUATION (CYCLING) SOUND.

- DI 60 - E2PROM: VALUE = 01 - 02 FOR CYLINDER MALFUNCTION. 00 = NO MALFUNTION.

- DI 61 - MALFUCTION HISTORY: VALUE = 11 TO 55, 00 = NO MALFUNTION.

- DI 62 - MALFUNTION HISTORY ERASE: 00 TO 21, 00 = NO MALFUNTION
TO ERASE HISTORY: TURN ENGINE STOP SWITCH TO OFF THEN BACK ON. DISPLAY SHOULD READ 00.

- DI 70 - CONTROL NMBER: DISPLAYS THE PROGRAM CONTROL NUMBER, VALUE = 00 - 255.

Thanks. Those will be helpful.

 Hey all,  What a great site! I've never posted here before, I always seem to find what I need.

I never read about or seen any discussion about this problem. My ride has been absolutley trouble free and I plan to put 100k or more on this bike. Probably the best bike I've ever owned and I'm riding  24 years.

I just replaced the orig battery on my  02 war (bought new in 04) with 30k and I did the diagnostic check.  I thought I might be having trouble with decompression solenoid.  The bike would ocassionally have a seamingly weak startup which would reset my clock and trip odo. The fuse is good and after doing the complete diag everything seemed to check out.  Although, I never heard any actuation (cycling) noise during the DI 55 check. Any other checks that I can do to see if the solenoid is actually working?   Any help or insight would be appreciated.  If anyone feels like calling me be my guest!  Thanks Rich. 321-446 -7965

Thats typically a sign your battery is on its way out.
