Need advice right now, PLEASE

[2012cliff]

Have bike at dealership. They say my ecu is fried. Their computer and their talks with triumph all confirm my bikes ecu will not engage. What do I do? 1- buy new ecu from triumph canada $ 1000.
2- buy a ecu off of ebay and hope it works. Is there anything i need to be aware of?
And then never play with my ecu again

I believe yours is the first I've ever heard of an ecu being fried (for the rockets anyway)! I'd be pretty confident off eBay, that if it was working before it will work still. Confident enough I'd still throw a good tune in it!

The bikes eu will not respond to laptop, not even triumps

I would buy one off of ebay , I have a very hard time trusting any dealer !

EXTEMELY rare to have a bricked ECU that is irrecoverable

I'd be looking for a fundamental wiring issue to the Diagnostic Connector

Edit - never mind, just found your other thread.
You should have been able to recover with the TuneECu recovery utility; I would still suspect you have something fundamentally wrong, especially if the Triumph tool can't communicate with it.

Ensure that Fuse 4 and also Fuse 6 are good

I've never actually tried this to see if it would help in this situation, but one suggestion I could make would be to remove the ECU Power Relay and jumper between the two Pink/Brown wire terminals. That can't do any harm, just completes the power loop that the ECU would normally complete to turn on that relay and then feeds power back into itself.


Buying a used ECU from EBay is probably pretty safe bet if that's what it comes down to.

This rates as one of the stupidest statements I've ever seen on here. You'd trust buying a second hand ECU from a stranger over a genuine new part supplied by Triumph? I can think of plenty of reasons why buying off ebay isn't such a bad idea but trust sure isn't one of them.

ECU's are very reliable - unless you have money to burn, then buying a used ECU from a bike that is being parted out is a pretty low risk in my book.
And many of the bigger breakers will offer a guarantee anyway.

It shouldn't be a case of 'not trusting' a dealer, simple economics.

I just recently saw a post on one of the Triumph forums on FB about a guy that bought an ECU off EBay for his Rocket, when it showed up the serial # had been covered up or removed, And it turned out it was an ECU for a speed triple.

Check out the Seller real good before buying

See this thread:



Particularly

Then I took a advice from a friend whom is also Triumph trained tech staff working for Triumph Taiwan, disconnect battery from bike, then turn-on ignition for 1 min, then off for 1 min, as this is one of off the book procedure they use when Triumph's diagnostic tool fail to download, this method supposedly will drain ECU Power and cause it to going to mode/state that will accept recovery download.

Then I begin to test with new cable no.3 (same supplier, same chipset, I just buy extra cable just in case if one does not work) + new installed of TuneECU 2.5 loaded with tune read from bike before (20446) - once connected, almost immediately the box appear “ECU is connected but not Responding, Run the Recovery?” Once recovery mode completed download 20446 Tune into ECU, the bike started up again no problem. I then process with tune download 20507 (Aftermarket muffler Tune) with no problem at all.

Of course substitute the relevant maps for your Rocket Application;
Open the map you retrieved from the ECU initially before attempting to reconnect.

Also from

Once again the procedure if the process load the map on the ECU fails.

In advance: always use the current TuneECU version and make sure that the correct FTDI drivers are installed.

For this process, in TuneECU must a suitable map to be open, at the best an OEM map.

- In TuneECU under options please remove the hook for automatic connections.
The option "automatically connect" with a few bikes makes problems.

- Choose the connection to the ECU via the menu "ECU" --- "Connect" .

- Make sure that your battery is fully charged and remove only the fuse for the front light or switch off the front light.

- Your computer you operate best with a power supply.

- Make sure that no energy-saving programs and no antivirus software is active.

- Switch on the ignition.
- The kill switch must be in run position.

- Now you need a lot of patience.

Now waiting for the message: "could not connect to the ECU, please check cable connection, please switch ignition off / on",
this message will come some times, you must confirm this message every time, after 2 or third time should see the following message:
"ECU is connected but not responding. RUN the ECU recovery ?"
After clicking on "OK", should start the process.

... when it showed up the serial # had been covered up or removed, And it turned out it was an ECU for a speed triple....

Check to see what type of ECU it is - the Late Model R3 (Roadster) ECU would be a 129-0650 on the Keihin label
