Tom or anybody...........I read this thread with great interest because I was getting ready to to the same. I downloaded the driver per your post. When I clicked on it (disconnected from the Internet) it opened what I refer to as a DOS box saying it was downloading the drivers. It happened so quickly, I couldn't determine where it was being filed. So I went to the "Device Manager", but was unable to find "Other Devices". So, I plugged in the cable and got a message that the driver had been installed. There was never a New Hardware Wizard and I'm certain the drivers are not installed because I was never able to find them. I've tried to locate them in the "Device Manager" but am unable to do so. My system is Widows 7 - any suggestions or am I just out of my league here?

Tom......I was looking at the unistalling information and was able to identify the driver located under "Ports (COM & LPT) and then "USB Serial Port (COMB). When I clicked on this, the box had "This Devise Is Working Properly". Is it possible the correct drivers are installed even though I didn't go through a series of dialogue boxes?????

Sorry to be such a pest, but I fear I only know enough to be dangerous.

Hi Jim,

You have the correct and current drivers download here ? http://www.ftdichip.com/Drivers/CDM/CDM20814_Setup.exe
And You have the CDM20814_Setup.exe performed ?
If so, then the correct drivers are installed.
Note: if the executable version of the driver is used (CDM20814_Setup.exe), then the Hardware Wizard does not displayed, that is so correct.

Best regards,

Tom

Thank you so much Tom!!!!! All of the information I had printed out showed dialogue boxes and a procedure for (2) drivers. I'm guessing the Windows 7 streamlines the process and eliminates those. Now to actually download your program. Again, thank you for your quick clarification!

While I have your attention, I was reading a thread elswhere on this forum just last evening where it was stated removing the O2 sensors affects the adaption process. Everything I had read previously regarding the Triumph twins highly recommends their removal. Does that make adaption not possible and/if so - that's something we needn't do?

There's a good explanation on TTP's site, I quote:

The Triumph twins use narrow band Lambda sensors to adjust the AFR (air/fuel ratio). Their job is to let the ECM know whether the engine is running at an air/fuel ratio of 14.7:1 under idle, light acceleration, and slow cruise conditions, and if it isn't, to “trim” the injector pulse-width to either slightly lean or slightly richen the mixture. When the ECM is paying attention to the input from the O2 sensor, the engine is operating in a “closed-loop” capacity. Under heavier acceleration or wide-open throttle the ECM ignores the O2 sensor because it requires an air/fuel ratio richer than 14.7:1, which is outside the design parameters of the narrow band sensor. This is known as “open-loop” operation. To summarize, a narrow band O2 sensor is only able to tell the ECM if the engine is operating above or below a 14.7:1 air/fuel ratio.

Our twins use “closed loop” operation at throttle openings under 6%, this enables Triumph to get the EFI air cooled twins through the strict manufacturers exhaust emission testing. In real life riding situations, this makes the throttle control at smaller openings a real pain and many owners describe it as rough and snatchy. This situation gets worse the more you open up the air box as the system struggles to keep the mixture correct and fights changes made to the fuel maps. Eventually with bored throttle bodies and pod filters the engine is running lean enough that it spits back through the induction system when slow speed cruising.

Twin Power disable the lambda sensors electronically for all our performance tunes. Using this method, the sensors can be removed completely and pluged. With the sensors removed, the ECM runs in “open loop” operation and takes its fuelling information from the adjustable fuel maps embedded in its memory. We have found that by disabling the sensors we can programme much smoother throttle control using the fuel tables without the conflict of the Lambda sensors trying to change the fuelling to how they perceive it should be.

Thanks Forchetto and I apologize for the double posts regarding this question. I couldn't find the other earlier for some reason - guess I need to scan the topics more slowly.

Forchetto

It's easily done. The forum moves so fast that a question asked the previous day on a thread, disappears beneath an avalanche of new oil, chain maintenance and what's going to be next years colour threads.

Best way to return to a thread that you're interested in is to bookmark it on your browser so you can recall it at a later date.

Couldn,t get the 20184 tune to load , I have ordered a new cable from lonelec and waiting for it to arrive, i can only guess the cable from China was faulty, I'll be back. Des

I DID IT, IT WORKED, Got a new cable from Lonelec (very quickly by air mail) and this cable worked, i uploaded tune 20184 for my 09 Speedmaster and all is good, many thanks to all who gave me advice and personal help. bike runs Great with no snatchiness just a very very small chugging feeling when creeping along in first gear (which may be the 270 Degree firing) very pleased and can't wait until Pieman comes out with his Speedmaster tune.Des

Good to hear that and thanks for the feedback.

Last year I tested several cables and found the Lonelec one was top quality and worked consistently well.

I ordered an "OBD2 OBD II Diagnostic USB Cable For KKL409.1 VAG-COM 409" from Amazon.com; the comments for that product indicated that several people had used it with TuneECM with good success on their Triumphs. The first one that arrived seemed to load drivers okay onto a couple of laptops (one WinXP & one Win7) as per instructions, but TuneECM would not connect when the cable was plugged into my Tiger 800XC's diagnostic port. It appeared that there was a fault in the cable, so I returned it to Amazon and ordered another one, which has now arrived. The second cable has minor differences in appearance, but it is labeled "KKL VAG-COM for 409.1"; however, with this cable, neither of the laptops will load any drivers. I have gone through the steps outlined by Tom to first remove any old drivers and then reinstall drivers. The drivers continually fail to load when the cable is inserted into the USB ports, even when I point the installer to where the files are stored. Using Device Manager, I have observed that this device's name is simply "USB2.0-Serial", whereas the first cable was named something else (I don't remember what the first one was called in Device Manager, but I know that it wasn't USB2.0-Serial). Is there anyway that I can get this "USB2.0-Serial" cable to work? Or should I send it back and try a third cable? Is there a good distributor in the USA who sells the proper cable at an inexpensive price?
