MyECU not seen by Optimiser or ECU Controller
03/12/12 at 02:11:38

Yesterday bike started and ran with My15M, rough between idle and 3000rpm but cleared and pulled well above that, did not go over 4,500rpm and returned home. Left things as they were and went to bed intending to carry on tuning today.

Today to my suprise the Optimiser screen stayed blank when switching on the ignition.

Tried plugging in the laptop with MyECU Controller 151, no data was displayed. The laptop was the same one I used yesterday, Control Panel showed the USB serial port as port 7, this is the same as set in MYECU Controller Config.

Tried reloading the sport.ecu map supplied by Cliff. The MyECU Controller display went through the usual string of text but did not start working through the cells, just kept repeating this string '07481B009000283E', difficult to be sure that is exactly right as keeps flashing on and off. I suppose this string is waiting for the MyECU to answer.

The RJ45 socket looks OK, no contact wires crossed over etc. I am using seperate leads for the Optimiser and MyECU Controller.

The fuel pump still runs briefly when turning on the ignition and my multimeter still shows the expected outputs from the TPS so current must be getting to it from the My15M.

The spark plugs do not fire so of course no start.

Bike started immediately when refitting the IAW15M.

Any faultfinding tips or ideas? Undecided

Sounds like it isn't getting 5V. Check the capacitor on the Optimiser near the RJ45 has 5V across it.

OK, 5v at the Optimiser but could only read that if I earthed to the bike.

Worked backwards along the earth path and found burnt pcb track on the My15M between D16 leg of the RJ45 and R32.

Soldered in a link and Optimiser now posts normally.

Too late to run engine now, will try tommorow afternoon. Don't see how that fault would stop the My15M though.

The 5V regulator and the Poly should have limited the current. C17 may have dumped its charge but really its a small cap. That seems unlikely the culprit How do you think it happened.

Don't know. All seemed well when I parked the bike up the previous evening.

The track was not totally burnt, rather it was lifted up along one edge, the green laquer was intact. I was not sure if it was the fault and flicked it with my fingernail, it lifted up in two pieces. I could not see any sign of scoring or mechanical damage. I suppose it is possible I may have overheated it during assembly.

Soldering in the link seems to have cured it, or do you think I have'nt really found the fault just the result of some other defect. You may recall I did have problems with the initial assembly particularly with the voltage boost although it seemed to operate OK yesterday. Huh

I found the damaged track after following your advice.

I looked closer at the Optimiser it is not displaying normal output, more like when testing before hooking up to MyECU.

MyECU controller not displaying data/baros, tried reloading map but stops at the repeating string.

Should I reload firmware?, where do I get it.

Tried downlading ECu, is this just no Map in ECU or is the map corrrupt.

Out of space on YaBB, map stops at end of Spark table.

# TDC is the pulse count for TDC power stroke of cylinder 1 ( i.e. When the spark fires
# CylOffs is the number of degrees between success cylinders ( 0-720)
# PulsesPer is the number of pulses for the 720 degree 4 stroke cycle

MyECU Cfg TDC=0x0, CylOffs=0, PulsesPer=0, MissingPulses=0

# CoilCharge is the period in us for charging the coils. 0 for cranking, 1 for running
# Warning, Setting coil charge too high can cook the output transistors and coils

MyECU Cfg CoilCharge0=0,CoilCharge1=0

# Pressure - mV and mB values defines a line representing the air pressure conversion

MyECU Cfg Pressure=0mV,0mB,0mV,0mB

# There are 8 possible voltage targets available 0-7
# The first number for 0 should be 0.0 and means open loop
# For simple sensors where richer is more voltage, all numbers should be positive
# For later sensors where leaner is more voltage, all numbers should be negative

MyECU Cfg O2=0.00V,0.00V,0.00V,0.00V,0.00V,0.00V,0.00V,0.00V,
# 0 = None, 1 = Inp1, 2 = Inp2, 3 = Both
MyECU Cfg O2Sensors=0

# RPM specifies the maximum RPM.
# TPS specifies the throttle value at idle (no fast idle).

MyECU Cfg RPM=0, TPS=0

# TDCWhileCranking=1 will fire the spark at TDC
# TDCWhileCranking=0 will fire with advance from the map

MyECU Cfg TDCWhileCranking=0

Bluetooth

# This table relates to the injector open/close times as a function of voltage
# The value here is roughly the time ( in us )
# 16V 15V 14V 13V 12V 11V 10V 9V

InjVOn 0 0 0 0 0 0 0 0

# TempR gives the value in ohms of the NTC temperature sensor

OK, cable made according to instructions on you Firmware Updates page. I used 49 Ohm resistors as I had them.

I could not work out how to download the AVRDUDE program from the link you gave me, I have downloaded AVRDUDE 5.4 from the website below, I hope that is OK. I ran the program under CMD and it looks right and seems to have the parameters noted in the instructions.

Are the instructions on the Firmware Update page up to date? I ask as I see it mentions My16M in the command line.

http://tinkerlog.com/2007/07/15/avrdude-54-for-windows/

The instructions state the ecu must be powered during the update, is this as plugged into the bike with the ignition on or by a seperate power supply?

Perhaps you could send me the file when you have time.

Again, thankyou.

I have upgraded from bike's power, and from 9V battery. I have even upgraded an Optimiser powered from ECU which in turn was powered from 9V battery. It should be fully charged though... I used a rechargable.

Last time I upgraded stuff I modifed an old junk power supply so it provides 5V (for Optimiser) through an RJ-45. Naturally, this means I will never have to upgrade an Optimiser again, lol...
