New ECU Flash Option: DIY FLASHING
- Thread starter avc8130
- Start date
Thanks for the tips AC! I have worked with this type of connector and locking pins before and you are right, they are a bit pf a PIA. I didn't even think about checking the existing pins to make sure I don't dislodge any of them. Good call. I will make sure to do that.
I plan to solder all the connections but will have to see exactly how when I get into it.
Thanks again,
John

There is only 1 connection not completely done for you. You will have a bare black wire from the harness to deal with. You can either tap it to the black w/ blue wire in the ECU harness as directed in the manual (a Scotchlock is included, I chose a Posi-Tap, soldering is always welcome) OR you can put an eyelet on it and just run it right to a good ground.
All of the other wires come pre-crimped with ECU connector pins.

I just ordered a kit from flash-tune. I broke a bone in my foot last saturday so I won't be able to ride for possibly several months. Perfect time to screw around with this stuff (maybe even sneak in a casted test ride).
I've been getting caught up with reading this thread and really like the idea of having this capability. Of primary concern to me is being able to flash back to the stock EU map when inspection time rolls around. Too bad Flash-Tune can only provide a backup of what's currently on your ECU. I have the Diapason flash, and would have fun playing with that, but would really like an OEM EU map as well. I checked the map sharing section at Flash tune, but there's nothing being shared among S10 owners yet. Hopefully someone will send theirs in (stock EU flashed ECU). 8) would love to have both backups.

You get the OEM map from Flash Tune when you buy the interface.Tenerator12 said:
When you buy the interface, you automatically get access to 2 maps: Stock ECU and their "91 pump gas map".
You would also have access to your flash if you send in your ECU and let them pull the file.
I'm 99% sure FT has the EU stock map and you would get that with your interface.
Of course nothing is being shared...everyone is too caught up with the ECU-U gen 2 magic. Once a few more guys get the interfaces and make some maps, there will be more.

I'm having great success with the GuzziDiag (free) reader, writer and using TunerPro (free version) to modify the maps. I had a big flat spot below 3500 rpm on the Griso, turns out there was NO advance and too much fuel. Trimmed some fuel out and put in some advance to sorta fair into the rest of the map. Presto, no more flat spot!
I wonder who writes the factory maps, damn! Must be just trying to make EPA guidelines.
Working on trimming a little fuel off in the cruise zone of 65 to 75 mph to get a little better MPG.
If they had this when I had the Super Ten, I would be all over it.

Thanks, that's very helpful info. I'll exchange a few emails with Flashtune. I plan to send my ECU once the riding season is over, because I definitely want access to the Diapason file for the purpose of: #1. Satisfying my curiosity about what exactly they've changed, and in what way. #2. To see if I can smooth out the injector cutoff just prior to the throttle closing. AND, if I can access the area where Diapason programmed the ECU to switch to T-mode on shutdown, I'll change that in a heartbeatavc8130 said:
@twinrider: That's good to know...just bolt the stock headers back on for inspection, LOL! Still good to know that flashtune provides a stock file though. If I sell the bike one day, I'll probably return the ECU to stock settings. It also might be fun to flash the stock 'S' mode map into the 'T' mode position for a side by side comparison between that and the Diapason flash.
That is pretty much what I did. I run an "unrestricted" S mode in my T mode slot. I run a SS mode in my S spot with a quick turn throttle map and the more advanced timing FT suggests.Tenerator12 said:
T mode provides a nice, linear throttle, with timing suitable for regular gas. Perfect for dirt or highway, or bad fuel.
S mode provides a FAST and hard throttle hit, along with a bit extra grunt from the timing. It needs premium fuel and my attention.

OK, I was just nosing around in the 'CJM explained' thread, and here is where there's some sort of gap in the info or maybe just a gap between my ears. In the CJM thread, you showed what the CJM did with the throttle restrictions and ignition timing when compared with stock. How did you read a file that is currently in the ECU, or did Chris get that info for you? This sort of thing drives the nerd in me crazy.
Thanks.
Thanks.
Correct. When the whole process started I sent my ECU to FT so they could extract the factory flash and make sure their interface/software would work with the Tenere ECU (essentially that is the same "hardware" as an R1/R6 they already support).Tenerator12 said:OK, I was just nosing around in the 'CJM explained' thread, and here is where there's some sort of gap in the info or maybe just a gap between my ears.

Anyone buying the interface with a STOCK ECU need not send them the ECU as he already has the "stock" file to supply.
If someone has an aftermarket flash, I would suggest sending the ECU to get that flash extracted before over-writing it with a home brew flash.
The interface cannot "read" the ECU, it merely overwrites whatever information is on the ECU each time the user "flashes".

OK, so Chris jumpered the clutch switch and extracted the info. Gotcha. Didn't mean to put you through repeating what you had carefully explained earlier. Just wanted to connect the dots, because it started to appear as if there was exeptions to the rule. Thanks.avc8130 said:

Not quite, but sure. The CJM just commands the ECU to make decisions based on its "neutral" gear position.Tenerator12 said:
Think about that for a moment. Let it sink in. With the CJM, the operator is telling the bike to fuel/throttle/ignition/etc based on being in NEUTRAL. A condition that has no load, no wind, nothing. Doesn't seem like the best idea.

So, They did not pull it from the bike with the ECU on the bike with the Jumper in and the bike run on a Dyno?
So they ASSUME it is a neutral MAP!
I never believed the part about the timing anyway. Just didn't make sense.
I still believe the Clutch Jumper only removes the Throttle delay just as Tmode is increased delay and Smode is less delay CJmode is NO DELAY. Has nothing to do with timing or fuel.
Pull a MAP with it hooked to the bike on a DYNO and then post the MAP. Not from the bench.

I understand your point. But your own info shows that other than Wide-Open-Throttle, (in the upper gears?) there wasn't anything "alarming" about that neutral programming.avc8130 said:
It might not have been the optimum programming for riding the bike, but for many of us, we enjoyed what we believed was a much more ridable and enjoyable bike in the lower gears.
(I use past tense since I am now Gen2 and no longer need the CJM assist)
We also now know, thanks to you, that a non-flashed bike owner could choose to put a cjm switch on his bike and simply turn the cjm "off" as he goes from urban commute riding to high speed highway.
Having said all that, the ECU programming choices we now have kind of renders the CJM concept obsolete. And it IS progress! But the CJM programming served me well for many months before the Gen2 flash was even available.

Well sure, cheap option. Doesn't mean it is a "good" option.snakebitten said:
I rode around with the CJM for 13k miles before I got the FT flash. There was no information to know better. Now there is.
I see the CJM as a new "opportunity". I could add a switch and have a 3rd map to go along with S and SS.
In fact, maybe I will do just that. I'll "fix" the WOT timing, and the cruise timing, and do something silly with the throttle. Maybe make it a joke for when I let others ride the bike. "Limp Mode" with a max of 25% throttle or something.

Wait a second. That's cool!avc8130 said:
You could use the FT tool and reprogram that "neutral" programming, then access that neutral programming as a 3rd "mode" via the clutch switch?
Clever, indeed.
