As I speculated in post #14 of this thread, the following OBD2 to USB cable should connect the Delphi MT05 ECM to a computer. :)

The following photograph shows all the components of the Delphi EFI system employed by the Zongshen RX3.

Here are links to various components of the EFI system which are sold at Tabao.

That would be a good point of negotiation. Even half price would be nice.

so is there a an adapter cable available to go from the delphi plug on the rx3,,,to my obd2 scan tool?? if so i want one.

I don't know of any adapter cable which will connect the Delphi plug to an OBD2 scan tool. :shrug: Therefore, I am going to make one, using the parts I mentioned in post #33 of this thread.

obd2
 

if it works,,,can you make me one ,,,i would be happy to pay ,,an you gotta make a profit.Or at least show us what to buy an how to wire it,,, ,....thx,,,,,,,,,,,,fish

I'm sure the plug will work, but I will verify it operates properly after the bikes arrive, and I can test it. ;) At that time I will post a thread on the topic, with photos. If you wish, I can also make an adapter for you. :)

obd2
 

you should just make them and sell them,,,,seriuosly,,,make a little profit for all your hard work an research,,,,,,,il buy 2.

obd2
 

Thanks spud,,,,,,dang i cant wait to get my bike now!!

adapter cable
 

this cable should also worked on the harley system ,,,correct?

I don't know about the Harley Davidson system, since I haven't seen a diagram of their OBD2 conector. :shrug:

Here is a link to the Delphi throttle body for the RX3 at Taobao.

Great thread Spud,

I was told by my Odes UTV dealer and by a tech at Odes that the Delphi KF90121 Motor Scan Diag tool could remap the ECU, My dealer let me use his to see if I could figure it out and I couldn't, the diag box has a USB connection and from the Odes site picture it has CD's so I'm thinking it needs to be connected to a computer and software is needed. No software or manual was with the Motor Scan tool they lent me.
I also have contacted Dobeck and they are investigating if they can produce a fuel tuner.

I hope someone figures out a way to remap the fuel system with Delphi EFI systems

I am considering loaning my Zongshen RX3 to Dobeck Performance so they can develop an EJK controller for this bike. :) The Dobeck EJK (Electronic Jet Kit) allows you to enrich, or lean the fuel mixture to your preference for idle/cruise, acceleration, and full throttle. Therefore, you can tailor the bike's fuel economy and performance exactly as you wish, and easily change any of these settings at your convenience. :tup:

Welcome! You have an Odes UTV? If so, please feel free to start a thread on it and show us pics.

These guys seem to be having fun and making some progress with connecting the Delphi MT05 to a laptop.

click on the ckayaTb PCHUD.rar link for the software.

this seems to be old win 3.1 software (16bit) which wont run on my win 7 (64bit) so haven't been able to run it .

it should run on XP or Win7 (32bit) in compatibility mode.:)

Thanks for posting the interesting links. :)

what the software can be freading and flashing a ecu?

Interesting thread..... I like to see what's going on with any vehicles I have so think I'll be making up a lead to see if I can connect to the OBD port, got an assortment of diagnostic software and adapters so see what I can do. If I have any luck I will share the results on this forum :-)

Thank you. We are still awaiting the arrival of our bikes in North America, so we will be pleased to learn any information you have to share. :)

That would be terrific!

Honestly, the skill set of our members is amazing.

Right I'm going to spend the day looking into making an OBD connector for this bike, see on the wiring diagram there is 6 wires to the diagnostics port, both K-line and canbus connections..... I will try the K-line first (easiest) and see if my diagnostic gear picks up anything then look into the canbus connection ... I see there is a note on Delphi's pinout diagram for the ECU that canbus is used for ECM development only so maybe caution needed, wouldn't want to disable my bike .....

I'm pretty someone (Spud, perhaps?) found an OBDII adapter for the Delphi connector. Perhaps that would take some risk out.

Post #33 of this thread should provide the information you need. The Delphi connector employs only three wires, one of which is the K line. ;)

Diagnostics
 

Made up a lead, connected to the port and nothing, no data being picked up from the K Line on my bike :-( Will have to try the canbus connections next, I've included a pic of the port pinout. I'm wondering if pin 5 is equivalent to a L line connection needed to 'wake up' the K Line communications? Any thoughts? Attached pic of the OBD adapter lead I've made, probes for 12+, ground and K-Line.

Look what I've found on good old ebay,,,,I wonder if it's worth a try: http://www.ebay.co.uk/itm/KAWASAKI-6...item2594f846cf

Not a bad price, if it will do what you need.

The Harley Davidsons use the Delphi MT05 ECM.........lots of tuning interfaces available to do your own fuel mapping for them,mmmmm now then it must be research time ;-)

Delphi flashing tool
 

Hi

Here is SW for flashing Delphi MT05 ECUs

http://bitbox.ru/en/catalog/1

Maybe someone needed for tuning

cheers

Thanks for posting the link. :)

btw harley MT05 differents from all chineese

Mt05 and mt05.2 using all around has K-line to communicate
Harley MT05 - using CAN


so any tools for harley will not work

Thank you for posting that good information. :)

I have found a USB connector that looks like it might connect a laptop running the PCHUD software to the Delphi Mt05 diagnosis plug.

(I haven't checked the plug but it looks about right)

(reference to RX3 in description)

and here I think is the same item on Taobao

http://item.taobao.com/item.htm?spm=...ucket=2#detail

the description suggests it might come with software.


Its a long shot but you never know it might just work ;)

Thanks for posting the link, Kat. You are quickly becoming a Taobao Guru. ;)

Nice work! Are you going to buy one?

Yeah, have one on order

I couldn't resist :D

but it will probably all end in frustration and tears :cry:

:)

I doubt it; I bet you'll be blazing a new trail for us.

I agree with Weld. You have the true, China Riders spirit of experimentation and innovation. :)

Cheers for the info on the difference between MT05 ecus used on our bikes and Harleys Samcool, saves me splashing out on diagnostics that wouldn't work.

Small Update
 

I now have the software, it came via email, just waiting for lead to be shipped.
The software is PCHUD that we have already but importantly it came with 2 Delphi MT05 parameter files and USB drivers.
One of the parameter files is in Chinese so I have been busy trying to translating it.

I have seen pictures of it all working on other Chinese bikes that use the Delphi MT05 ECU but alas not on an RX3.
Still, I think its all looking quite promising :)
