V7 Rev/Stall/Surge Guzzidiag Help Please

[Jerry421a]

Please Help!!!

I have a 2014 V7 single throttle body dual o2 sensors.  It is having a problem similarly described by others.  It revs very high on cold start up (3-5k) and then stalls.  If I can get it warmed up it has a surging idle and also surges under moderate load.  Each time the throttle is pulled the engine sustains the rev and then drops to almost a stall.

I have Guzzidiag and cables.  Last year the bike did the same thing.  I was able to clear the autolearning parameters and reset the throttle position sensor.  That did not fix it.  I then cleared the stored data and then auto learning, and TPS reset.  That worked.  It rode all year great.  I let it sit for a month this winter and the problem is back.

Now with Guzzidiag I get an error message when I try to clear the stored data.  Auto learning and TPS reset give the the OK. 

I run the adapter test and get a success notice.  Last year I was able to download my MAP with the reader.  I don't know what to do with it.  This year I get an "failed to initialize" when I try to read the map.  My thought was to try using one of Mike's maps that seam to work for others but I cannot seem to get the software to work properly.

Any help or pointers would be greatly appreciated.  I have spent many hours looking at tutorials, instructions, and such and this is as far as I have been able to make it.  I live in Idaho and the nearest dealer is 600 miles one way and when I talk to them on the phone they do not inspire me with enough confidence to take the bike to them. 

Thanks

"Failed to initialize" usually means something like:

Wrong port selected

Another program has grabbed the port

Bad cable

Battery voltage too low

Wrong bike selected in GuzziDiag.

So for this latest work, have you successfully connected to your ECU using Guzzidiag?  (sounds like a yes? or was that a while back?)

If so, then you know your laptop/driver/cable set up is working right.  So it should be easy to get the reader going. 

For the Reader, if you've never used it before, are you sure you downloaded the correct version for your bike? 

If you have the right version, and good cables/driver, then the only thing left is picking the correct Com port.  It would be the same com port number you used with Guzzidiag.  That could have changed if you've done stuff to your laptop (like 6 months ago it could have been COM4 and now it could be COM5 if you've added extra stuff on your laptop).

Easiest way to check this ...
- don't have the cable connected to your laptop
- start the Reader, look at the list of com ports (let's say you see COM1-COM3)
- exit Reader
- connect your cable to your laptop, give it a few seconds to realized it is on there
- start the Reader again, look at the list of com ports ... the new one in that list is your cable (like now you'll see a COM4 or COM12, basically 1 more than before)
