As usual, you are correct, Kat. ;)

The blue, 2-pin connector provides data to the ECU for engine temperature. The black wire feeds data to the digital dashboard, and powers the fuel bar display at the right side of the dashboard. The thermostat housing has an internal thermostat, which opens, and allows coolant flow when temperatures reach 70 degrees Celsius.

The thermal switch, which turns on the radiator fans, is located at the bottom of the left radiator.

It seems the mega download links in the OP are not working anymore. Would someone kindly share a working copy of the PCHUD software?

Thanks for confirming, spud:)

By the way , great job on your workshop manual tutorials, brilliant :tup:

The Mega website has pulled some of my files,
I have posted 2 new links on my profile visitor messages page ( click on the kat !) :tup:

Thanks for reposting the files, Katflap. And thanks to everyone (Katflap especially) for creating this great resource for RX3 owners!

Sorry for butting in...most of this thread is in a foreign language to me.

What software/scanning tool does CSC use? I read that they will loan it out if necessary.

jb

Thank you, Kat.

I assume CSC is renting/loaning the Delphi Motor Scan Tool KF90121. Here is a link to eBay where one is selling for $400. :wtf:

http://www.ebay.com/itm/Delphi-Motor...3D321895273165

Following the lead of Katflap, I bought the proper cable and run PCHud software on a laptop computer for a lot less money, and much more diagnostic power. :tup:

The engine warning light on the digital dashboard will flash DTC (diagnostic trouble codes). You can also buy several scan tools on Alibaba, or Taobao, which will communicate with the Delphi EFI system. However, those tools usually cost about $180.

I tried ordering the red cable today without luck. When I copy the URL into my taobaotrends shopping cart it doesnt load, remains blank. The Taobao ad list several as being in stock. I've order through taobaotrends before without a hitch so I'm puzzled by the failure this time.

You probably need to set your Taobao page to 'Mainland China.' ;) If you have more problems, contact your Taobao agent. He can help you correct the problem. :)

Hi folks.
PCHUD archive links are broken today.
Can you please help ?

If you can't download the files, I suggest you send a personal message to forum member Katflap.

Thanks I'll do that.
cheers !

Quick diy lead using http://www.ebay.com/itm/VAG-COM-KKL-...993964&vxp=mtr and modifying one of these http://www.ebay.com/itm/Extension-Co...466724&vxp=mtr works with PCHud
Plus you have the option to connect other OBD devices to the bike using the second modded lead :-)

Modded OBD lead to suit RX3 Port
 

This is the lead I have made to connect to the VAG KKL to USB adaptor for running PCHud on the laptop. Also I have been able to connect other scanners / adaptors to the bike using my lead :-)

I have ordered similar cable to ebay: http://www.ebay.fr/itm/262367188038?...%3AMEBIDX%3AIT

Waiting for delivery to try this out ! :)

I have constructed a similar cable, but it failed to connect my MaxiScan MS309 to the Delphi ECU in my RX3.

https://a248.e.akamai.net/f/248/9241...0324773552.jpg

Therefore, I reckoned the Delphi ECU software was not completely OBD2 compliant. :hmm:

Have you had success reading a diagnostic trouble code (DTC) with another OBD2 compliant scanner? If so, please tell me which scanner(s) you have successfully connected to the Delphi ECU of the RX3. :) I have my cable handy, and I am eager to try another scanner. ;)

If I can find an OBD2 scanner which will read and erase codes from the Delphi ECU, I will post a thread showing how to obtain the proper parts to fabricate the cable. Then everyone will have the option to carry a compact OBD2 scanner along with them when they depart on trips, et cetera. :)

OBD scanner I used is Innova 3110
 

Hi Spud, my scanner connected, detected the protocol and showed no DTCs present,

Hi Muzo, you will also need to make the OBD to RX3 cable as in my post #95 to connect the VAG KKL lead.

My cheap scanner attempts to link with Keyword 2000, but doesn't connect with the Delphi ECU. :hmm:

If you disconnect the O2 sensor, or disconnect the cable for the ignition coil, do you get the appropriate trouble code? Can you reconnect the cable, and clear the trouble code with the OBD2 scanner?

My MaxiScan MS309 scanner works with my automobile, but not my RX3. :shrug: I'm pretty sure the Delphi ECUs in our CSC bikes have a different version of the software than the Honely bikes. Perhaps this is the problem?

http://www.autelscanner.com/products...MS309_749.html

spud, i missed it if you said, did you verify your scanner is functioning on a automobile? very interesting hack .

i know network wiring is very temperamental from the little experience i have had with Ethernet cable transforming.

Yes, my MaxiScan MS309 works with my automobile. ;)

After trying what you suggested Spud it seems my scanner although shows connected it didn't pick up the DTC :-( Still shows no DTC's stored. PCHud did pick up error 49 so glad that works :-)

Thanks for checking. :)

The PCHud software does work well. :) Apparently we need a Delphi Scan Tool, or its equivalent, to connect to the Delphi ECU via scanner. ;)

OBD Protocol?
 

After looking more into PCHud I came across a presentation by John Boreham from Delphi where he mentions the protocol used by the software is ALDL, it's an OBD1 one originally used by General Motor so maybe the reason why our OBD2 scanners might detect but not be able to communicate with the ecu. Worth looking into further.

Enjoy 4 mins of full-on 100% genuine RX3 data on your Windows 64bit computer. Using the new PCHUD simulator from katflap productions.
:crazy:

Ok, settle down, here we go ;)

This is the first stage of trying to get pchud to run on windows 64bit.
It Is fully functional pchud, but i still need to get the pesky com ports to work so it can't, as yet recieve a live data feed from your bike. But i'm working on it !

The download contains 2 installers
1/ dosbox ( this is free software from the internet)
2/ PCHUD64 ( This is my stuff)

Both come with uninstallers

Disclaimer - I'm not an expert so use at your own risk !!
http://www85.zippyshare.com/v/1KGRWK06/file.html

instructions, in this order -

Install dosbox,
Install pchud64
now you can launch dosbox from the shortcut it has created on your desktop.
after a short time you will see pchud on your screen.
-------------------------------------------------------

To play back data in pchud -

select the playback tab,
select open playback,
select k_flap.ply, then press ok button,
press the forward button in the main pchud screen and it will begin to play,
put your feet up and geek away!

---------------------------------------------------------------

shutting down pchud --

select the file tab,
select exit.
after a short while you will see a blank screen with " c:\> "
type " exit " but without the quotes and it will exit and return you to your desk top screen.

If you run in to problems, which i don't think you will, you can yank the plug from the wall socket :lmao: or use these key commands
CTRL-F9 will quit dosbox
CTRL-F10 will restore mouse
ALT-ENTER or
ALT-RETURN will toggle fullscreen to a window screen

-------------------------------------------------------------------

a bit of info on the playback file i included ----

I was wanting to see how the fuel trims would react when presented with a rich mixture. so during this recording, about 3 or 4 times, i sprayed some butane gas in to the air box.
On one occasion it stalled the bike.
At about 3mins 25 i got it right and you can see the short term fuel trims (C L STFT COUNT, C L CORR FACT) go negative and dropping the pulse width to compensate for the rich mixture also the stepper motor opens the idle air control valve to let more air in.

Another note, it takes quite a long time before the "stable warm idle" to indicate at around 60-70 degs C

Last thing, pchud loads my latest par file, i will be posting notes on this soon ( you can select others)

:)

I believe that PCHUD is a really useful tool to have and use but, for me the problem has been understanding what it is telling me.

This is my attempt at doing just that.

Its worth remembering that though trouble fault codes are very useful the "MIL" light will only come on when problems have reached a point where the ECU can no longer compensate or beyond an acceptable limit.

Thanks for posting this good information, Kat. :tup:

[QUOTE=katflap;215367]part2,

(apparently wen an O2 sensor fails it will leave your engine running rich)

Not necessarily. When the sensor fails the engine should revert to open loop, where this a base map telling the injectors to fire. The base map is still modified by input from various sensors. If the base map is rich across the board, then you will have a rich running engine. It is fairly common to disable the O2 sensor input and rely just on the base map...after that base map has been modified. REXXER dealers do this for Marelli ECUs and maybe others. In most cases the modification is done while the bike is on a dyno. The drawback is that dyno runs are done under ideal conditions, not real world. If one can do real time data logging and then map modification you would have the best of all worlds. My Stelvio has a real time data logged map, O2 sensors disabled, and runs great.

Thanks pyoungbl,

I must have read it wrong or perhaps taken it out of context, :doh:

Unfortunatley I have know experience of this stuff prior to getting my RX3 so input from yourself and others who have "hands on" experience is very much appreciated. :tup:

katflap, I want to thank you for the link to details about how the Delphi EFI works. That was the first time I saw any mention of open loop operation on this ECU. Every other reference only mentioned closed loop. The specific condition mentioned was open loop under hard acceleration. That makes sense, getting the most power possible and to hell with a lean burn. I suspect that is the same logic used by the larger capacity bikes when they switch from closed to open at around 3500-4000 rpm, a liter bike can cruise along at 3500 rpm with no difficulty but for sudden acceleration rev up and get max power above that range. The Zong, on the other hand, is really pretty gutless below about 4.5K so it would be interesting to find where the switch happens. At 60 mph I bet we are running open loop due to wind resistance if for no other reason. All this is fascinating for me but my bike runs so good that I see no reason to make any changes. I agree with you and Spud, it would be great to have a hand held device (smart phone?) that would provide diagnostics. Please continue your research and keep us informed.

Kat;

Would something like this work with an adapter?
http://www.ebay.com/itm/BAFX-Bluetoo...699259&vxp=mtr

I doubt it will work. The Delphi MT05 ECU does not appear to be OBD2 compliant, or it would work with any OBD2 scanner, which it does not. ;)

As far as I know, the Delphi MT05 controller is proven to communicate only with PCHUD software running on a Microsoft Windows computer, and these two, compatible scan tools.

1. Delphi Scan Tool KF90121
2. ED100 Motorcycle Scan Tool

PCHUD software is easily the least expensive, and most powerful tool for diagnosing the health of the Delphi MT05 ECU.

I still think it's a cool piece of hardware and software. Now I'm wondering about a windows tablet . Use it with the proper software and a cable .... there's a couple of windows based tablets on ebay for decent prices.

Hi folks.
I've seen a video of a russian guy running openDiagFree on a MT05.
It was set in KWP2000 mode.
Unfortunately, I cannot use it as button texts are not translated into non russian language.

interesting !

When I get chance I will do some tests to see if I can discover when it drops in and out of closed loop, it would be interesting to know. :tup:

I agree the present EFI setup works well, trying to understand how it works and diagnosis is what tweaks my interest rather than modifying :)

In addition to what spud has already said,

there have been a few people try a bluetooth connection but I believe without success. Also I have tried the Torque app with an android emulator with know success but admittedly it could be a connection issue between the com port and the emulator.
