Just went and test-fitted mine, set to position 4 (Speed Triple 885).

Fired right up and idled, revved free sitting still, seems to actually run a LOT smoother than the stock ECU.

Headed out for an ill-advised night time test run with the stock ECU and a flashlight in my backpack.

I'll post results in a bit, hopefully.

That is excellent news.
Congratulations on the best buy on an ECU in the History of Triumph Motorcycles.

Not so much.

I didn't like the 4 setting, so I stopped and changed it to 7 (the correct setting for my bike) after a couple of blocks. Ran okay, just didn't seem right somehow. I trust my feelings, so I changed it.

She ran beautifully! Idle was rock-steady at 1400, the engine was quieter (I kid you not) noticeably smoother and more responsive from idle to 8000. I didn't rev her past 8K because there wasn't room. It even seemed to correct what I thought was a float problem- no idling down to a stall at red lights.

10 miles into the ride, she lost power and died on the highway.

Pulled over, noticed I had lost the neutral light.

Swapped the old ECU back in, she fired right up. Hurray, headed home.

2 miles from home, she died again. I suspect a blown motor, I'll know more in the morning.

Symptoms- Lost power, when I hit the clutch the motor stopped dead. Wouldn't turn over on the starter. Sounded hydro-locked but smelled strongly of oil. No smoke. WOT and hit the starter and she grudgingly turned over.

Let her sit for 45 minutes until my boss got there with his truck. Managed to get her started, and she ran okay for about half a mile, and then I lost power again and things started ticking in the top end. I held the tach at 4K and she kept running - so I ran redlights and stopsigns the mile and a half home, got into my apartment complex, and as soon as I hit the clutch the motor stopped dead. 4000 RPM to 0 instantly. Coasted to my parking spot and told my boss that I was calling in a pedestrian so I could either diagnose the bike, buy a cheap car (today was payday, thank God) or both.

I have NO idea what's wrong. I didn't run her any harder with the new ECU than I do every day. Not as hard, probably.

I'm going to pull the valve cover tonight or tomorrow morning and see if the timing chain is okay, pull an oil sample to check for metal in the oil, and see if I can borrow a bore-scope from someone to check the pistons/sleeves.

She sounds sick unto death. I am not all that hopeful.

On the bright side, if the motor is hosed, I have a perfect excuse to put in those 955i internals and cams I have been wanting to do anyway. We can rebuild her, make her faster- stronger. Better.

If you have one of those ECUs and haven't fitted it yet... DON'T!

Wow, Merlyn. That's terrible. I'm really sorry to read this.

I wonder if this Procom ECU has overheated the ignition coils? It seems an incredible coincidence to 'blow' or damage the motor after running with this new igniter eh? (That ticking from the top could be the coils too?) These engines in stock form are pretty hard to break.

BTW the Speed Triple advance curve is a few degrees more retarded at most points (maybe all?), so would explain a smoother feeling motor.

IRL may have the deal.
Another guy in my office and I were brain storming and thought
the box fouled the spark plugs.

Pre ignition should not destroy an engine, an ECU cant stop the lubercation.

Its carbs so it can not tell the fuel mixture to thin out too much to hurt it.

I thought plugs....IRL may be right with coil(s).

I'm hoping. I am going to go pick up a cheap car in about 10 minutes so I know I have transportation tomorrow (I'm a mobile computer tech - if I don't have dependable wheels by tomorrow morning, I'm unemployed), and then come home and tear into her. I've been wracking my brain all night, and my biggest concern is the timing chain. If the timing was off a bit, it might have stressed it enough to make the chain jump a tooth. She was running really smooth, but you never know.

Course, Belle being Belle, i may go out there and she fires right up and runs like a sewing machine. That has actually happened once before- I was fiddling with the carbs, and she ran like crap all the way home from the garage I use. Just barely made it. Went out the next morning and she purred like a kitten.

Time to get off my arse and get it done - I'll start a thread once get started for this one.

Dang. Last Saturday my triumph would not start..
I had a thumper 500 that would not start if is sat for more than a couple weeks. I think the bowls were low. So, I did with the Triumph what I would do with my FT500.....try and try then walk away for a day.
I told my pal Sunday, watch, now this will start. In the 1st second it fired up.

I wont even try to pretend to know why. wet plugs,,,,,
low float....
stale gas... karma fairy dust... i have no clue.

I contacted the company through ebay. They responded unbelievably fast!

They are going to send another one eventually.

So everyone should contact them!!!
