So....let me get this straight - there are now several reports of the ECU failing when connected to the GP Control software and trying to run diagnostics or download maps? JayBR & DirtHawg - is that what you guys are reporting? I'm thinking ahout getting the GP software but if it could potentially fry my ECU then I don't wanna spend the $300.

 

I've talked to Optimum, Cannondale, and R&S about this. Don't really have any specifics but since I am a software engineer and my background is in computer hardware I'll fill in the blanks.

Apparently there is an occasional problem on some ECU's that if they loose connection the OP code gets corrupted. The thing that is unclear is does a bad ECU cause the dropped connection or does a dropped connection corrupt the ECU. I could test this but don't want to risk another ECU. I was told that in some cases the OP code could be reloaded successfully but not always.

The guys at Optimum say that if the problem occurs it is because of a faulty ECU and that reloading the OP code is only a temporary fix and the problem will eventually re-occur. Optimum also says that the software has no way of corrupting the OP code so it must be a hardware failure. If what Optimum says is correct, there are some ECU's out there that are bad, but the problem will only show up if your doing mapping. This could only be early ones, but I don't have any data on that. My Speed is #24.

If this is correct then using the software would not fry an ECU but could identify a bad one. The other issue is that it may take awhile for the problem to surface. I've had the software about a month and loaded different maps sucessfully on several occasions. Tough call if your out of warranty, but Cannondale is taking care of mine.

If the ECU's are not faulty then its a design problem on the Optimum side of things. I've got some ideas, but without knowing any architectural details of the software I'm only speculating.

 

Something I just thought of:

My Speed was subjected to a to service bulletin SBA01-11 entitled "Starter solenoid kickback voltage and MC1000 ECU damage" Maybe the root of my recent failure is a problem that was caused prior to this fix being applied.

 

OK, got another ECU this afternoon, installed it, read the map off of it, update injector flow rate, TPS, etc. Sending the updates to the ECM it lost communications again and I'm back to the same problem. I'm really starting to think this is a software issue, the failure on Wednesday happened as I was trying to update the TPS, that was the first time I had done that, same thing today. Guess I won't be riding today as planned, and I just blew $40 on overnight shipping with saturday delivery. This is really pissing me off now, I think if I had the software to reload the OP code I would probably have been up and running a couple days ago.

Another thing, Cannondale has a parts bulletin that states the maintenance and diag software has been upgraded from version 1.1 to 2.0 as of 5/22, I just purchased mine last month from Optimum and they sent me version 1.1. The bulletin also states that version 2.0 has the ability to load OP code.

 

all this talk about computer problems is scary. how long is the warranty on a c-dale? all this extra mapping, can you really tell a difference? i have tooo much money invested in a 2 stroke to switch to a four stroke, but i'm really glad all these new four strokes are coming out. maybe after honda and yamaha come out with a racing quad i will be able to get a new one. i would hate to buy one now and yamaha come out with a killer yz426 racing quad. airtime

 

airtime,

Did you upgrade from win 3.1 to 3.5 cleanly? or win 95 to 98? or any other uupgrade. There are a few bugs in the system that are being worked on. Part of being cutting edge.

Jay,

Call optima back and have them send you 2.0, they should for fee.

1.1 will install operating code when you boot up the computer you need to have freedos in the floppy disc cannondale will supply this free.I think you only need it if you are running windows 2000 or newer.

 

Well, I got my new computer and it says unprogrammed on the label. I have ver. 1.1 and need to know what I need to do inorder to get my ECU running properly. Optimum is only open M-F to get the code for the new ECU. So, when I get the code does anyone have ideas on what I need to do? Do I need to download the OP code? I guess I'm a little confused on what needs to be done. I thought I could download the Moto map and tweak the settings for Injector Offset and that would be it. Any help here would be appreciated. Thanks!

I specifically asked about this the other day and they said maintenance adn Diag wouldn't load OP code. The bottom line is they sent me an outdated version of the software.

The other issue is no support after normal business hours. It's one of the nicest weekends we've had in awhile, I had a bunch of friends that wanted me to ride yesterday, and the Dale isn't running because of a software problem.

 

I used dealer cal1.1 to install operating code many times.Maybe it only works in dealer cal.Normally when we get a new comp. all you have to do is match the variables and map.The new computer should have the correct operating code H302V03M.HEX.If you dont, print out bulletin SB02-008 from cannondale website then check your files in the same place your maps are stored it should have the icon with
H302V03M.HEX under the icon if it doesnt you obviously cant download the operating code.
