Guzzidaz Help

[old head]

ok,
I order the cables from LonElec, installed the drivers. 
96 Breva 1100 stock setup

downloaed guzzidag VO.46
 IAW5xwriter VO.21
IAW5x Reader VO.24

hooked it up and no joy.  I got the red triangle on the dash and the service warning on the dash?

I am also using a Shorai battery.  It cranks fine, drove it this morning.  When I disconnected everything it would not crank, shows three codes in dash errors under M, 1, 2, 3.  then I pulled and checked the fuses, and the relays, no change. started disconecting the battery and the service triangle went away and it fired right up.

I have the blue led on the cable, only have one port.  checked device manager, and it says

 USB serial port com3
 manufacturer FTDI
the device is working properly

Driver tab
driver provider  FTDI
date                3/9/2016
driver version 2.12.16.0

Running windows 10 on a touchscreen laptop

I only tried the reader, it comes on when I click it and when I hit read it asks where to save it, but nothing it isn't reading anything.

I have it in neutral, side stand down, tried recycling the key, reconnected everything a couple of times nothing.

stumped.....

Anyone have ideas?
Anyone done this that lives in SE Louisiana that would like to show me how to do it.

tried it again, same result, only this time the battery shows 12.8 volts on the dash, but won't crank again after hooking everything back up again.  hooked up the charger on 2amp trickle and it shows the battery with only 25% charge, weird..

I'm questioning the battery.
Thinly disguised bump to the top so someone that knows will tell you what's wrong..

[old head]

I hooked up a brand new battery from my boat to be sure there was sufficient juice,  No change still got the service triangle and no crank.  Dash does its dance fuel pump pressurized.

So I pulled and tested every fuse, all good.

resented every  relay I could find, no change.

Battery shows 13 volts and charger indicates full charge. 

started checking every connector all tight, except the MPH startus interruptus connection.  It pulled apart, pushed it back togeher and the service tirangle went away and it fired right up.  Weird, as I have never had an issue with the setup since I installed it years ago.

Anyway, it cranks and no service triangle now.

IT is really weird, but at any rate it is running.

tried again later, turned off my anti virus, and wifi. restarted pc.
hooked it up again, LED light on, hooked to pc, turned key on no indication that it is connected
opened guzzidag, says Breva 1100 disconnected.


Still any ideas as to why it won't connect.

Ignoring the READER and WRITER at the moment. Does GuzziDiag alone work? Did you download and try the AdapterTest?

If those work, you know that the reader and writer do NOT work at the same time as GuzziDiag? (only one program at a time can talk to the cable)

[drdwb]

For my Breva I had to use com port 4 which is sllected with a drop down box where you are reading com port 3 in preferences.

[old head]

ok,

I found an adapter test clicky from Beetle  ran it all is good now.

4th try seemed to be the trick.  finally go it to connect and save the OEM file to my computer.

next writer started but the battery died about halfway into the upload.

hooked up a charger and restarted the upload and it says done, whew!!!!

started Guzziday, reset the tps and learned parameters, so should be good to go

battery only shows 7.5 volts, so clearly something is amiss here.  Its a Shorai battery, it has been working fine in the warmer weather, don't ask it to start if below 60\

At any rate, it is on a charger now and we will see what happens after it is charged.

this is the second battery from Shorai, first one they replaced under warranty, I won't go back again.  the battery just doesn't perform when the battery is cool.  I will go with a AGM sealed battery I guess, same as OEM.

At any rate, I think everything is good at this point, can't wait to try out the programs that I got from Paul and Beetle.

Having the battery drop out during a write can permanently kill the ECU. Always safest to have a charger attached during a write.

Having the battery drop out during a write can permanently kill the ECU. Always safest to have a charger attached during a write.

 The ecu can't get locked when a write fails. With other programs maybe but not with guzzidiag. Why? before writing the old map is erased, but not all of it, the communication program stays always, so you can always restart writing. |It's correct that the bike won't work after a failed write, but can allways write again. Starting writing with a bad battery without chanrger connected is not the best idea.
Bad batterys are always a thing to solve first.

What Paul said.

I have tried to deliberately brick an ECU while using the GuzziDiag tools. Not going to happen.

[pete roper]

Not even I, the archetype of gurning Neanderthal, am able to brick an ECU using Guzzidiag. I've even managed to 'Un Brick' a couple that had had failed PADS writes! I'm not clever enough to know why but the customers were happy!

That is good to know.

But still sounds like something to avoid.

had I known the battery was weak, I would have done that.   It is a weird thing, as I rode it that morning to church and back, never gave me an indication that it was that weak.

At any rate, it has been on the charger overnight, and we will see what happens shortly.

thanks for all the input

went outside, battery fully charged, so says the trickle charger.

disconnected everything and it fired right up

it seemed to idle better than before and even started faster, maybe just my imagination but a ride is next on the list.  however, I have drawings piling up in my inbox to do from the weekend so the ride will have to wait.
