It's been a long time since I've been on this board, but I thought i would check in and provide an update.

As you all know I've made considerable efforts to get the ball rolling with MyECU. When I finally reached a point where I could download new maps I had a local Guzzi Guru help me out as sanity check. After a couple long saturday afternoons with several maps under my belt, I realized that the key to making this work is to start off with a good baseline map. Unfortunately...there doesn't seem to be one available. I tried all the maps that Cliff had to offer, and from some other board members as well, but they were either for other Guzzi models, used on a Guzzi California from a different year, or used on a bike that had been modified in some way. Who knows why none of these maps worked? The bikes could have different CAMS and other parts requiring different states of tune. My bike is bone stock.

Anyway, I reached a point where I didn't have the time to commit to what was going to be a very long project of creating a map from scratch. Then...I learned that someone in my area, who's posted on this board tonight as guzzisteve, had bought a MyECU! I decided to wait until he found a good baseline map that he might be willing to share. So, I've been waiting. Since guzzisteve posted a question tonight I thought I at least should post an update too. Hopefully Cliff and the board can help guzzisteve. In reality, if you're helping guzzisteve you'll be helping me too because where ever he ends up will be a starting point for me.

Thanks in advance!

Perhaps I've misread, but GuzziSteve didn't ask a question. Instead he gave a progress update and from what I read is doing well.

I don't have access to my email atm so I can't recall the details of your progress or lack there of. I'll check again when I get home.

Edit:-
Ok checked all your emails and really there is nothing there that says how the bike is running or what you have done.
A year ago you were talking about going closed loop. Did that happen?
You also didn't have a laptop to use the ECUController. Do you have something now?

If you get a map from Steve you will need to be careful as he has MyP8. The first part of the Map is specific to the type of ECU. So bring up both maps in notepad and find the line that says "Prime". It's about line 50.
Everything from the Prime line down you can change with Steve's.

Have you checked that the air pressure, air temperature and oil temperature that are displayed in the Optimiser's Barometrics menu are correct?

Everyone,

It's been a long time since I posted, so I thought I would provide an update. Let me respond to Cliff's thoughts.

If you read all the posts from the very beginning you'll notice that when I started this project I was told that I needed to acquire a vintage laptop with a vintage operating system to use the tuning software, plus acquire the right cable to communicate to the ECU. That took a while! Although some folks are running the tuning software on Vista or Windows 7 with varied success today, that wasn't the case when I started. Regardless, I found an old laptop with the right operating system, the right cable, and proceeded to try to use the ECU.

Then I found out the ECU had an issue which you graciously fixed for an additional charge (At this point over a year had passed since I bought the ECU so I understand the expense...even though it had never really been used).

All the gear; laptop, operating software, and cable, were owned by a friend who's really sharp when it comes to Guzzi's and tuning, so we where able to get a handle on what the ECU could do in a short amount of time. Very impressive! The big decision was do I pursue Open Loop or Closed Loop tuning? I headed down the Closed Loop path due to the baseline maps I found or received. They were so bad on my bike that I thought I could spend months trying to tweak it in Open Loop. Some of the members on this board have been down this long path. If I went Closed Loop, and used the Optimizer I bought from Cliff, plus added an O2 sensor to my exhaust, I should be able to ride the bike and it "practically-tunes-itself" (At least that's what I thought/think via several emails and suggestions).

Well, that means with Closed Loop I need to now buy an O2 sensor and bung to weld onto my exhaust, weld it, and then wire the sensor into my bike. I'm hoping all of that would work...but once again it's more expense and time.

So...instead I'm just watching guzzisteve's efforts.

We'll see.

I am currently working on tuning my Buell XB9R, and in the process, discovered a Bluetooth module for connecting to my PDA. Here is the link: http://www.sparkfun.com/products/10269 . I have not received my order yet, so I will update you as to how it works later. Also, there is some information about a USB to RS232 cable from FTDI at www.ecmspy.com. FTDI makes multiple cables, but among them is one that is for 5V logic like the MyECU has. Here is the link to the datasheet: http://www.ftdichip.com/Support/Documents/DataSheets/Cables/DS_USB_RS232_CABLES....
This is the cable I bought: TTL-232R-5V-WE. It is available from DigiKey http://www.digikey.com/product-detail/en/TTL-232R-5V-WE/768-1029-ND/2003494 ; for way less money than I paid on the FTDI site. The rest of the ECMSpy info is relative to Buells, so it can be ignored.

The majority of MyECU users stay open loop and have no issues modifying the map to suit their bike.

All you have to do is take the current map, make a guess and go say 5 or 10% richer across the board. Try it and see if it is better or worse. If it is worse try leaner.
As your map improves you can move the focus to specific areas of the map rather than across the board and reduce the % change.
It should take less than 1/2 dozen rides to get something on par with the OEM ECU.
It should take days not months.
It's been over a year since you I fixed the ECU and you still seem to be at the first step.

WRT to "needing to purchase a vintage laptop with a vintage OS", the context was that any old laptop would do the job and you didn't need to go and buy a new one.

Cliff - Thank you for the quick feedback!

You're correct that I'm at the same place I was a year ago, although much more informed and aware of the hurdles and additional expenses ahead. I truly want to make sure I'm leaving a positive impression for everyone, but also be helpful with a balanced post.

Through this little journey I've learned two key things:

1.) The MyECU and software is a combination of tools that will give you the most flexibility possible with tuning your engine. Truly the sky's the limit! It's amazing all the things you can control and adjust with your engine.

2.) It's not a plug-and-play device designed for a novice. You'll need to dedicate a considerable amount of time and effort learning what it can do, how to use it, and getting the proper equipment (laptop, cable, etc.) to tune correctly. Also, expect there may be some challenges setting up everything to communicate correctly. Once again, being a novice when it comes to setting up this stuff up means some delays.

I definitely put myself in the novice category, so that's probably part of reason for my slow progress. But, I do want to weigh-in that over time a general understanding can be attained for using it successfully.

Unfortunately, the idea that most people have their bikes fine tuned in a few days or weeks does not seem very likely. Who has the time to dedicate to this everyday? Sure, some might get things sorted quickly, but I think it takes trial-and-effort through a learning curve after using the system. Keep in mind, this is the opinion of a novice. Someone who barely understood the difference between Open and Closed Loop when I started. If you're like me the good news is you can get there, it just takes a while.

Also, the idea about using any old laptop...is wrong. The posts in this thread by several members clearly show challenges if you're using certain OS systems, com ports, or cables.

I've learned that guzzisteve is now on map #76. ...It just takes time.

I picked up one of your older postings. I say most, if not all, of the maps provided with the MyEcu or from other members should work acceptable also on your bike, the more as you say it's bone stock.
Using other peoples' maps requires that your bike has the same TPS setting (around 150 mV - look up this procedure in the shop manual) as theirs. Forget about cams or exhausts. Swapping the camshaft and/or the pipes ususally does not require changes to the stock map or WM ecu, for instance.
In case you've bought the MyEcu to cure any problems with your bike you're on the wrong trip. Go back to the OEM unit, properly tune your bike, and then give the MyEcu another try.
