Hi all
After some info on replacing an ECU on a 2014 Speed Triple R. Long story short...
Fuel pump primes when ignition turned on. Everything goes through the normal startup checks. Once engine is cranked the fuel pump does not come back on so bike dies.
I have had my mechanic spend a number of days on it, plus an ECU specialist go through the bike. Both have said they can't fault anything in the way of wiring/relays etc and that they can only out it down to the ECU. To get the bike working one of the relays has been pinned so that the pump runs all the time. With this done the bike runs like a dream.
So back to the original question, as I don't want to spend $3k for a new unit, how can I tell what other ECU I can buy from eBay or similar? What numbers on the casing if any do I need to match up?
Thanks for any input from the gurus

Without doing ask the homework, I'd suggest looking for ECUs for Speedys from 2014 to 2016, before the model change.
With that said, I had some very frustrating intermittent, that became constant starting issues between December and February just gone. I changed the fuel filter, flushed the fuel and replaced with fresh fuel, contemplated a new fuel pump, and fuel pressure regulator, and even new injectors and fuel rail.

It ended up being a faulty Fuel Pump Relay. It worker right up till when the starter button was pressed. My mechanic found that when started dealing out relays, he got it to start, and the ECU started throwing Fault Light and codes for the system that he swapped the Fuel Pump relay to.

The ECU seems like an expensive long shot... I'd get hold of another Relay and give it a try...

Note my Speedy is an 06 with 115,000 miles. So there may well be some notable differences between your 14 and my 06...

Thanks for the input Bad Santa. Relays have been checked and replaced.
Although I haven't done the work myself I think all avenues have been followed... Possibly.
So you think that as long as the replacement ECU is from the same year model that should work?

Yeah, the 14 to 16 models should run the same ECU type The only thing you may need to do is reflash the ECU with the map for your specific model (from memory 2017 was when they did their next big upgrade, and the ECUs were no longer owner reflashable).
If the donor bike is/was same spec as yours, it should be compatible.
People have mix and matched these ECUs before - but for simplicity, I'd get to one as close to your spec as possible - eg ABS etc, pre 2012 models didn't have ABS, so I'd steer clear of those etc.
