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. first some EFI basics http://www87.zippyshare.com/v/Umx8B0zW/file.html some more random "ply recordings" and my new hud and par file. http://www29.zippyshare.com/v/cLsvgmhN/file.html below is an attempt to explain Attachment 5747 Code:

part2,
(apparently wen an O2 sensor fails it will leave your engine running rich) Attachment 5758 Attachment 5759 |
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 https://www.youtube.com/watch?v=5bO5urN0Xeg |

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. |

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 :) |

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. |
