ECM SPY USB CABLE.

[a13fxr]

Hi all,This is my first time on this forum,So i would be grateful if someone could please answer why you have to have a special usb cable to run ECM SPY, The thing is i have a spare usb cable, which all i have to do is cut off one end & fit the Deutche plug in its place,which i have, I do know that the cable in question (FTDI)does have a chipset in the usb end, but what purpose does this have,
I'm hoping to run ECMSPY soon as i know i wont damage the ECM it self. Cheers.

The ECM is TTL, so you'd need a TTL to RS232 converter for serial, I'm not familiar with USB protocol.

Hi, someone told me that it could be done as usb's have superseded serial ports, is this not the case.
I just want to make sure before i try it. Cheers

You have to use a ttl level usb cable. The ecm can only handle 5 volts and this cable outputs that. If you don't use the ttl cable you will fry your ecm. Just go to http://xoptiinside.com/ and buy a cable kit. Mike is the man when it comes to this stuff!

Hi, Can anyone add any further comments regarding this
USB cable for ECM SPY.[confused]

Hi Loose1,
you say that the ECM can only handle 5 volts that is the same as what the USB gives out anyway, the thing is the Deutsch plug is wired without the 5 volt supply, only the Ground wire & also the receive data & transmit data wires are used. [confused]

So tell me this what all can ecm spy do. I just traded off a 2007 flht and everything had to be done with a power commander. I got a 2006 ulysses with 1550 miles on it it seems to be prety quick and runs smooth I would like to change exhaust though. Will ecm spy take care of the fuel air adjustments

I'm trying to find the pinout, but I'd think they're close enough. However, something is different, I have to find more info on TTL to find out what.

The USB to TTL converters for sale have some circuitry onboard, so obviously it's not the same, even though both are 5v with the same logic.

You can use it to read/write the fuel, timing, error codes, etc of the bike's computer(ECM). So you can change the fueling maps and everything for cheap without messing with a power commander.

i know nothing about computers and am too chicked shit to get into messing with my own ecm nor do i have the software. im pretty much planning on taking it up to the buell dealer and having them dyno tune it but was told that i first need to buy an ecmspy cable. im supposed to call tomorrow morning to get the full info. sound legit? im a collision technician and know how to fix dents, not tune engines lol.

 

[brightbuell]

what do they want to charge you at harley to tune your bike with a new exhaust on it?

 

[stang65pony]

im not 100 percent sure yet. i think its 400 bucks or something around there. i just dont know if i have the capabilities to properly tune my bike. i understand how a combustion engine works and all lol, but knowing what will happen if i change something minor is beyond my thinking capabilities. i just want this bitch to run top notch. just like it looks.

Stang,

I have a cable available for sale. I'll include the software, too. I recommend checking the forum for an updated version.

$30.00 shipped in the USA

 

[stang65pony]

i'll keep that in mind for when i find out more details.

You don't need to know how to custom tune to download race maps and burn them to your ecm. Nothing to really screw up.

Can Harley dealers even tune bikes? They're probably just going to load the updated maps into your bike and charge you $400. At most, maybe a $250 race ECM, then $150 to pop the seat and plug it in.

Go to a custom bike shop, something doesn't seem right. Dealers don't custom tune...

Ok, just asked another engineer that's done more with USB. Here's why you can't just do USB to TTL hardwired:

TTL is just a hardware connection standard. ~0v volts is a 0, ~5v is a low. There is no standard protocol, you have to define headers, start/stop bytes, packet size, checksum, etc. TTL is just raw 0's and 1's.

USB essentially uses the same thing, but has a set protocol. There's a whole language back and forth that has to be understood, packet structure, etc.

So, if you just connected everything and plugged it in, the USB would try polling the ECM using its protocol, which the ECM won't understand. The data could even harm it, if it happened to be the equivalent of a command to write a table or something. The USB on the computer won't understand anything the ECM responds back with, it's all 0's and 1' that don't meet USB protocol.

So, you'd need a controller between the USB and Buell ECM, to convert back and forth between raw TTL 0/1's and USB language. Or...a custom USB port on the computer with custom drivers. Much easier to use a USB-TTL converter.

Stang,

Any thoughts regarding the cable I have for sale? I plan to list it on the forums, if you do not want the item.

Hey a13fxr,

When you first run ECMSpy, click the "Konfiguration" link at the top, select "Programm" from the dropdown, and finally change the dropdown list labeled "Sprache" to "English" and hit the "Ok" button. Now those of us in the US can read it!!! Finally, select "View" from the links at the top and check "Professional". Now everything is visible.

Plug your custom USB cable into the bike and your PC, turn the key on the bike to ON. Click the button on the top that looks like a cable which will open a dialog box. Select "Auto detect" and it will locate your bike if the cable works. Now click the button on the top left of ECMSpy with the KEYS on it to connect to your bike. Your In.

ECMSpy comes with an excellent tutorial in the application on what to do so I wont go into it. Click the HELP link at the top and select "Tuning Guide" . You will need to download Adobe PDF viewer here http://www.adobe.com
