thirdcoaster I got mine today and it says and does the same thing yours is.  Since the cheap connector is not 100% the same as the ECU I wonder the pins are not aligning up correctly.

Hopefully the problem is just the connection, have you checked the continuity of the wires from the d-sub connector to the bike plug?

Out of interest if you open up the fi tools case what version is printed on the circuit board (between the mode and down buttons), mine is MOTO_V11.

I know this may sound stupid and I don't mean to offend anyone, but have you plugged it in to the bike the wrong way round, I just tried it then and it is possible to do.

The fi diagnostic tool should have the large catch on the same side as the catch on the bikes plug like this1383966038352.jpg

Hey all, after that last post about plugging it in the right way, I hooked up the fi tool and guess what no connection!

So I got a flat blade screwdriver and pushed the pins down so they are level with the bottom of the recess where they protrude like this 1383967010903.jpg

And what do you know it works again.

If this happens to mine, I will cut off the plug that comes with the diagnostic tool, and solder on small alligator clips, so I can clip directly onto the pins inside the Yamaha ECU plug and ensure that there is a good solid connection.

 

If it does indeed end up being the crappy Chinese plug, then I will build an adapter that uses the end from the GYTR tuner to ALSO connect the diagnostic tool. At least we all know the GYTR plug works.

That sounds like there's a broken wire or maybe a dry solder joint on the circuit board, do you have a multimeter that you can use to test it?

I opened that box but i didnt found anything,and now i connect it again and now it works.It must be bad connection on that 9 pin plug.

I tight it a bit and now it works.

That's good that you got it working,

When I first received mine it needed the female d_sub (9 pin connector) on the unit pushed down so the cable could seat, the plastic housing was catching it.

Sounds like it's time to send it back and get a replacement.

Update...my circuit board version is MOTO_V11 so that is encouraging. A basic continuity check indicates that the cables are good and yes, I had the bike's connector plugged in right. I tweaked the 3 pins to be sure of good contact and......"connecting....." continues. Maybe throwing it down the driveway would help? LOL

Thanks for all of the suggestions. Fortunately, the only starting issue I have is having to hit the starter button 3 times on every cold start, hot start is just a touch of the button.

My problem was starting in hot when i buy this bike,i removed start and drive almost year whitout it.Now i replaced piston ja chain and put startmotor back.Now it wont start hot or gold.But it starts easy first or second kick.

It's a shame there seems to be such a high DOA on the fi diagnosis tools. China still has a way to go it seems.

Are you going to seek a replacement?

My bike was the exact opposite of yours, it would fire almost every time cold with the cold start button, but get some heat into it and all bets were off.

I received the scanner this week and just got done trying to use it. It turns on but it will not connect.

 

I decided to stop by the Yamaha dealer again because of the aggravation, to see if they could or would adjust the fuel at idle. They never would tell me if they could adjust the idle fuel. They were essentially unwilling to take my money to adjust the low idle fuel only.

With the high failure rate of the Chinese fi diagnostic tools, I had a look around at the genuine Yamaha fi diagnostic tool, the part number is 90890-03182, some times shown as 90890-03182-00, it can be yours for about USD $155 off eBay.

Unfortunately it doesn't have the right plug, but this can be solved with either making a patch lead with the two plug styles on each end or simply replace the end with the right one.

The connectors can be bought from a website called eastern beaver (no it's not one of those sites).

As far as I can tell the Yamaha fi tool has the same colour wires to the plug as the GYTR tuner so getting the pin out right should be straight forward.1384045211850.jpg1384045231005.jpg1384045247951.jpg

Once again, nice work Boston. At least those of us that bought the Chinese POS will have a plug that we can use for the Yamaha unit.

 

Maybe we should split the price and just send this from person to person? Once the adjustment is made, it shouldn't need to be tweaked again.... right?

      I am currently rebuilding my yfz450. I decided to buy the hot rods 500cc stroker kit. I was wondering what jets I need to run. It has full fmf exhaust, uni filter, riding at 800ft. Above sea level. I currently have a ncqv needle on hand along with 170 through 180 main jets, and 45 through 55 slow jets. I don't want to do the trial and error thing for two weeks, what should I start with?

      1991 DR250S Dual Sport STREET LEGAL, with only 2,263 original miles. This bike is extremely clean and very well maintained. Clean title. Bike is all stock except for the grips, tires, and mini rear turn signals. Has a Cheng shing rear 4.00" knobby, and a Shinko 244 front tire, under 1,000 miles on it. Everything on the bike works perfect. The pictures do not do this bike any justice, must see in person. Comes with everything in picture plus:

      -passenger pegs 
      -the license plate bracket plastic (currently removed for a less bulky look, as seen in pics)
      -a cheng shin front knobby (the matching rear is currently on the bike)
      -a 4.60x18 Shinko 244 dual sport rear tire (brand new, 0 miles, matching front is currently on bike)
      -spare turn signals, new in box
      -original owners manual 

      Located just outside Schenectady NY. Only selling because I'm looking to pick up a '01 or newer rm250, which would be the only trade. Price is firm. No spammers, no tire kickers. SOLD AS IS. local pickup only, if you really want the bike shipped, that is for you to set up and pay for.

      hey all, yesterday had a DNF from an engine issue, well got it home and in a couple hours of washing and tear down found out it had broke an exhaust valve... the bike has aprox 260 hrs all together, obviously i never thought about when i should be replacing valves, top end has about 60-70 hrs on it (hour meter fell off and didnt notice for a race or too... oops.)  it didnt damage anything it looks like other than the valve and the piston. 
      so onto my questions. 
      im looking at all the valve options. i have lapped many a valve and have even done a few 3 angles myself. but i dont know which one i should go with being all relatively equally priced? are stainless just as good? if my titanium lasted this long should i just put oem's back in?
      only really asking because i am extremely hard on the bike (3 hour races brutal dust and mud constantly tapped out in 5th.) 
      also because ive seen alot of engine carnage but have never seen a valve break like this.

      Hi all.  New/old rider here.  Im 37.  Havent raced or ridden for that matter since 2000.  Got kids now.  One on a 2018 CRF50.  Hes 6.  So I got a bike to be able to ride with him and maybe get into racing again for myself.  Found a clean 19 hour 15 YZ250f.  Bike is in immaculate shape.  BUT......
       
      What is the trick to get it to start easy??  Something seems wrong.  I have been watching youtube videos about the 15+ YZ250F's and other 250F bikes and they all seem to start with one kick.  No need to find TDC or anything like that.  Warm or cold.  With mine its very sensitive about starting and needs to be at TDC no matter the temp.  Its very annoying.  First time I tried to start it, it took 20 minutes and I was already tired.  Then I went looking for info and found about all this TDC stuff.  And that would be fine if I wasnt seeing TONs of videos of people getting their new 15, 16, 17 YZ250F's and starting them in one kick.  Something has to be wrong.  This bike is 2 years old with 19 hours on it.  Original owner said it was maintained very well.  Didnt get a chance to ask him about its starting, and I dont want to bother him.  But it seems wrong.  Its not like its a 2000 or something with 150 hours on it.  
       
      What could be the issue?  Valves needing adjustment?  New plug maybe??  I have no issue getting it to the dealer for a valve adjustment.  Just wondering what others think.
       
      Thanks.
