Hello everyone I am having trouble flashing a 21h70 ecu. I am able to data log with ecueditor with live data but when I flip the switch to flash the ecu I get an error. This is the error I recieved: "Unexpected or missing ECU response during intialization. Programming aborted, reset ecu and reprogram. 0.0"
latest ftdi drivers
ecueditor pcb version 1.3c
The label you are giving is for the 08 1K.
The ecu plug you will be going to is the black one not the Gray. Pin 15 TX goes to RX on the interface and 16 RX goes to TX on the interface. Reset goes to pin 17 and FWE/mod goes to pin 29.
If you wire to the Grey ECU plug you will never have success. I hate to tell you how I know that. The Grey plug has numbers and empty spots in all the right places but, the numbers on the plug are not ECU numbers.
I have the pins right but im also programming the ecu off the bike. Are there other pins i must connect?
I solved the issue, I had a broken wire. thanks busa quick for your help.
Jay , we spoke a while ago by email , but yea im stuck right here , i can read the ecu , but not flash , i didnt buy the right switch so im manually changing wires for TONIGHT only ill buy the switch i saw the right one at the store, ill get it tomorrow, i built the same thing except i built a bench harness i took woolich racings image of their k8 bench flash harness saved it and used that to confirm where pins need to go i found a power wall wart at 12 volts 1 amp and sacraficed that, plugged that into my bread board power from wall wart goes to 12 and ground goes to 36 , i looked at woolich racing image to determine this, hope that doesnt pi** anyone off lol i got desperate was about to buy the thing but then noticed i could make out what i needed.So , i can read the ecu ive done that twice but i can not flash ?
I got it working not sure how ? re did some wires , messed with the circuit , took my time with it , and now i can read and flash k8 ecu , but i have no idea what to do to get rid of IMMO , i flashed k8 750 to it put it in the bike with the crossover harness and it turned and turned but did not start im guessing IMMO got me stuck
