The New Improved GuzziDiag Tutorial

[beetle]

OK, so now what do I do with this?

You can check & clear DTC's (errors). Test some things. Look at sensor readings, etc.

What should I tweak or check on my 07 Breva 750 (completely stock incl exhausts)?

Throttle body balance & TPS reset is a good place to start

Is there a better map?

Probably not.

Is a full diagnostics suite that can assist in running down other issues?

Yes.

[Rapier]

Not like I needed a reason to get / make more cables. 
Thanks beetle, this is going to be fun!

Thanks beetle.

I did the TPS reset and reset of the throttle learning, and it now looks like:



What does your previous advice of 3.6 for the Breva throttle refer to?

I presume you mean autolearning?

3.1 is in spec.

Thanks beetle.

I'll actually take it for a ride tomorrow.

Guzzi’s instructions for the grip install say to reset the TPS, as the demand sensor is replaced with the grips.  I’ll see how it runs without the reset.
Was really just wondering if there’s an issue with the Mac version of GuzziDiag.  I can’t get it to run on either my personal or work laptop.

Hi, any luck with this?  I put heated grips on my v85 and it seems to run fine without resetting the TPS, however, I live in fear of something going wrong later on and would rather not take it to the dealer. I have the lonelec cables from my Norge, still waiting for the adapter.  I also use a Mac, but did have connection issues with my Norge but did manage to get it to work after much fiddling.
Thanks for any advice, Kris

I’ve tried everything I can think of and have had no luck with my Mac.  Will not connect.
Need to borrow a windows machine and try again.

Or just install a dual boot (bootcamp?) or a virtual machine qith W10. You can install W10 just from download from microsoft, works without license, might complain after a while.

Hi Beetle,

I really appreciate your contribution with this tutorial!

At the top of the TPS reset tutorial you mention that the v11's as an exception. I didn't see any mention on the 1100's in the "Thoughts on TPS" post (unless I'm missing something  ). Does the TPS need to be reset on an 1100 (I have a 2000 Jackal)? Does this require different steps?

Thanks!

[beetle]

Huh? I mention the 1100 twice. In the "thoughts" post, & TPS reset post. I thought it was clear? Maybe not? I'll edit it.

No, do not reset the TPS on the 15x ECU on any 1100 or California variant.

Gah, I must have missed it then. Lots of jumping between posts, sorry. Thanks for clarifying!

First time post, just got access to forum this morning.  I been following Beetle/Guzzidiag.  I have a 2012 V7R, it has mistral carbon exhaust, baffled, 15RC, dual throttle bodies.  Ordered the cables and over the weekend download and saved the original map. And I uploaded the v7c lamda off nopop Beetle map.  The bike ran better, I assume that the original map was factory, not sure but the CRC was 505C.  The bike runs better, more alive through the rev ranges after.  I play with both co trim +3 and +4. 

I have some follow up questions:
1. I notice +4 had more pops vs +3, when I come off throttle to a stop.  let me know if that observation is even accurate.
2. does the co trim only affect idle mixture or it's in affect all the time through the rpm range?
3. is the idle rpm fully control by the ecu?  The bike idle a little low bounce between 950-1050, when warm
4. if idle rpm fully control by ecu, is it better to adjust the throttle with a little play or no play? or even positive play?  b/c either way, we are resetting the TPS?

side note the bike wants to die at start, warm or cold(worst), but I will post a different thread.  This thread alone was so helpful, I donate $10 to the forum, thanks for sharing all the information.

1. I notice +4 had more pops vs +3, when I come off throttle to a stop.  let me know if that observation is even accurate.

Quite likely. CO trim adds a fixed time to the real-time injection pulse, so this behaviour is not unusual.

2. does the co trim only affect idle mixture or it's in affect all the time through the rpm range?

Entire RPM range.

3. is the idle rpm fully control by the ecu?  The bike idle a little low bounce between 950-1050, when warm

Yes. It uses the ignition advance, but it's highly dependent on the throttle position.

4. if idle rpm fully control by ecu, is it better to adjust the throttle with a little play or no play? or even positive play?  b/c either way, we are resetting the TPS?

You want minimal play without affecting the throttle. That is, the butterfly must be closed with the twist grip fully closed. Moving the bars fully left to right should have no affect on the throttle.

First, have you balanced the throttle bodies? If not, do so, including TPS reset. TPS should be 3.1-3.6.

First, have you balanced the throttle bodies? If not, do so, including TPS reset. TPS should be 3.1-3.6.

The TB was balanced in Dec 2019 at 3500 RPM and at idle.  and yesterday I balance the idle only.  Since I haven't touch the linkage screw it should remains the same for 3500 RPM.  Yesterday, I did the new map, then TB balance at idle, then TPS reset. It usually sits at 3.1. The idle issue has been there since I bought it in Nov 2019, it only has 3000 miles.

And I don't know if it's really an issue, maybe it's just guzzi.  I am just not used to it.  If I rode it for 30mins, park it for 15 mins, ambient temp is 55F, I have to choke it 1/8 to keep it from dying for 30-40sec.  Or I sit there and rev it for maybe 30 sec until it steadies.  I expect it to just start normally without any assistance and idle smoothly after a short stop in kinda warm weather.

I can tweak the map for you, if you want?

[needanotherbike]

Absolutely, if map tweak can fix this idling issue.  If you can gloss over what's happening to cause this behavior, and why a map could fix would be good for general knowledge.

Also questions during CO trim, I read that I can do live adjustment but I want to clarify #6 below:

1.  view>actors>CO Trim
2.  <engine must be off> [click ok]
3.  [click start]
4.  <Gentlemen, Please start your engine!> [me start the bike] [click ok]
5.  [me make changes to the CO trim]
6.  at this point in time,  the bike still running...
     - I can just keep adjusting until I am happy with the idle
     - keeping in mind to leave 20-30sec of observation btw adjustments
     - so the CO trim is a live adjustment?  and it's only saved to the ECU when we kill switch?
7.  [me click done] [kill switch + and ignition off]

please lmk if my understanding on #6 is correct?  Also is it worth getting a CO meter to help?

[beetle]

The CO trim is a live adjustment. The final value is set when you click "done". Please wait ~20 seconds before you hit the kill switch.

I wouldn't bother with the CO meter. Simply set CO until the idle is steady. That's why it's best to wait between adjustments. It allows for any delays in response from the engine as the ECU makes changes.

If you have to set the CO so that the idle is good, but it smells of fuel, that's the point where I suggest tweaking the fuel map.

Anyone in the Maryland area who has experience with GuzziDiag?
I will want to set up my 02 EV at some point in the near future.

[mcstark]

First time post.  I picked up a 2016 Stornello with 6 miles on it a couple weeks ago.  She seemed very cold blooded and didn't want to idle on her own.  Once warmed up the bike ran fine.  Thanks to GuzziDiag and this tutorial, I verified the V796 map is loaded on my bike, reset the throttle and auto-learning parameters.  Now it starts almost immediately and settles into a even 1500 rpm idle - it's been below freezing here, so no time for a real ride.

I just wanted to thank Beetle for his work.  I plan to ride the bike on the stock map until at least my break-in mileage is done.  Then I'll decide which way to go.

[gregmurf]

Hi all,
when you reset TPS following beetle advices (on a 5AM and a single throttle body), you just have to fire uo your engine ? wait for 1 minute at idle ? Wait until fan goes on ? Or no need to wait ==> startup engine and ride ?
Thanks

[beetle]

Start & ride.

 

[Breadandstuff]

Thank you for all of your hard work! I just ordered the cables for my 2018 v7iii !!

All the bikes will take the same cables I am hoping?

[beetle]

All, except the V85tt. It has the new Euro5 connector.

Hi,
On my Quota 1000 1997, P8 ECU, wich reader and wich writer should I use?
I couldn't find the propper one on the Guzzi Diag page - https://www.von-der-salierburg.de/download/GuzziDiag/
Thanks

[beetle]

The P8 doesn't have that capability. There is no Reader or Writer available.

[Breadandstuff]

The P8 doesn't have that capability. There is no Reader or Writer available.

Which reader writer is needed for the V7? Am unsure what the differences between 5AM,7SM,MIU G3, 15, etc. ECU's are

[beetle]

Your V7-III has the MIUG3 ECU.

[Nicholas]

The P8 doesn't have that capability. There is no Reader or Writer available.

Thank you very much
In the meantime, I've managed to check my IAW P8 PF09 ECU, and I bother you with another question: what should be the correct voltage on TPS (Throttle V)? is the GuzziDiag reading correct or should I check with a voltmeter on TPS socket? The displayed value in GuzziDiag is 0.392 V for idle
And what is the correct setting for CO Trimm, initial was 97 and the engine seems to run smoother at 65, at 50 the engine almost stalled

[beetle]

Don't use the voltage readout from GuzziDiag to set the TPS. The resolution isn't accurate enough to set the TPS. You can use the throttle value reading, however. If you want to set it via a voltmeter, connect directly to the TPS.

CO trim? Set it to wherever the bike runs best.

[beard]

For setting the closed throttle value of 150mV you can not use GuzziDiag, because the ECU starts sending this value from ~300mV onwards.
If you then want to set the idle value, you can use the normal throttle value in GuzziDiag and set it via the screw to the value which is written in the manual.
It doesn't matter if the value is exact or not, because the ECU use this value to find the map entries.
