Hello everyone,

Does anyone know where Pin 17 (reset) and Pin 29 (fwe) terminate after they come out of the ecu? What I mean is they exit the ECU with their respective wires, do they terminate at a specific point, another connector perhaps?

Forget the above, I found the answer. Cheers

Hi All, pretty new to this so apologies for being so late to this subject.

I am looking for some instruction for making your own ecu flash interface. I understand you need a USB - TTL cable as a base but I am struggling to find the rest of the info on how to make up a interface cable for a K7 gixxer 1000 for use with ecueditor.

I would really appreciate a point in the right direction if possible. I understand you can buy these from woolich but i did want to have a go at making one.

Thanks

Why would you bother? You can buy a USB -> RS232 cable for about $7.

Very true, and its the next steps of getting a plug and wiring it up for a K7 1000 that i am finding hard to locate. Please don't hold back if i am blind

What plug? Not sure what interface the K7/8 uses.

Have a look here -> http://ecuhacking.activeboard.com/t14784871/instructions-to-build-an-interface-to-flash-the-2002-2007-bu/?sort=newestFirst&page=1

Gixxer rob what plugs are you looking to find? The ECU plug so you can bench flash or the Yoshi and SDS plugs?

 

[gixxer.rob]

For the price of the usb cable, perhaps all of the plugs so I can make a few different cable setups. A bench setup with ecu plug and a in bike setup with the sds yosh plugs. Do you guys have any recommendations ?

 

[kwaka10r]

I think Mouser has some of the ECU plugs.

The K5/K6 ECM plugs had different key locations (and colors) and were not interchangeable. For K7/K8 one ECM plug is JAE MX23A36SF1 (I think).

Most other connectors are available from Eastern Beaver, among others. The 8 position SAP connector (body/pins/seals) is available as Kawasaki part 26011-1773. The 6 position SDS connector body is Sumitomo 6187-6561. Pins & seals are separate.

Hope you know what you're doing.

As above, does anyone have a schematic of the on bike harness for a K7 1000 running through the SDS and Yosh connectors?

Thanks in advance!

The K5/K6 ECM plugs had different key locations (and colors) and were not interchangeable. For K7/K8 one ECM plug is JAE MX34036SF1 (I think). Check your ECM as it may be used in both locations.

Most other connectors are available from Eastern Beaver, among others. The 8 position SAP connector (body/pins/seals) is available as Kawasaki part 26011-1773. The 6 position SDS connector body is Sumitomo 6187-6561. Pins & seals are separate.

Thanks for the info about the plugs, yes the K7/K8 have two of the same plugs on the ECU.

I understand to flash in bike that i need to insert two wires in the ECU connector pin 17and pin 29 and and across to location #8 and location #5 on the yosh connector. But it is the construction of the flash interface using a pre built USB TTL cable like listed above and the SDS and Yosh plugs that i am wanting to make and any info that I can be pointed to would be awesome. Like the units sold by boost by smith or woolich.

If successful I wouldn't mind having a go at the bench flash harness as well.

Did you look at the schematic in the second link from post #446.

Link here again http://www.bikeland.info/pdf/ecu/USB-ECU_Interface_Hayabusa.pdf

Here is another excellent source of connectors and they are located in the US Corsa-Technic. The advantage over Mouser is that they are complete with seals and terminals. Mouser I think you have to order them all one by one.

You may be better off heading over to the ECU hacking forum. There are some guys here doing it, but not sure about the K7.

 

[gixxer.rob]

Yes thank you very much for the pdf, that looks like the kind of info I am after but it looks different to what I think I need. The diagram shows only the yosh plug connection and what I can see I need the yosh and sds. But as I am not 100% I am asking the question. I will do some research on ecu hacking forum.

Yes I found a great and very detailed guide for the K5/K6 1000 but no good for me.

Thank you for your help so far.

 

[kwaka10r]

I think the answer is in post #1.

Extra two wires in the ECM plug and they go to the Yosh connector.

If the ECM is out of the bike then you need the ECM plug.

I now think I got the K7 & up ECM connector part number wrong above. Furthermore pictures and JAE drawings suggest that the two connectors are not the same but have different keying as in K5/K6. As best I can tell, the JAE part numbers are MX23A36SF1 for the black plug and MX23A36SF2 for the grey.

 

[T.R.E]

The ECU plugs are different you will need the black one,not the grey.

I think the answer is in post #1. Extra two wires in the ECM plug and they go to the Yosh connector.

The difference reflects two approaches to the interface. The first juggles existing wires around on the connectors so that only the Yosh/SAP connector is needed for flashing. Nothing new is needed. I've never been a fan of this approach because of all the changes. The second, used by Greg Smith, adds two wires from the ECM to unused positions on the Yosh/SAP connector. This requires that both the Yosh/SAP and the dealer mode connectors be used for flashing. Additional pins for the new wires are needed. But in terms of modifications to the wiring, the second approach leaves the harness much closer to its original configuration.
