There were many reasons for the change of the site software, the biggest was security. The age of the old software also meant no server updates for certain programs. There are many benefits to the new software, one of the biggest is the mobile functionality. Ill fix up some stuff in the coming days, we'll also try to get some of the old addons back or the data imported back into the site like the garage. To create a thread or to reply with a post is basically the same as it was in the prior software. The default style of the site is light colored, but i temporarily added a darker colored style, to change you can find a link at the bottom of the site.
Have you had an ECU Flash? How long did it take? Any good?

Stage 2
Anxiously awaiting that report...but doesn’t their website say 2 tankfuls of gas to fully “learn” new configuration?

That’s interesting, JS.....my advice from Jase was to take it easy for the first 20km, and then let it rip...... which I did. There was no “2 tankfulls” mentioned......and I find the powerband and throttle response significantly improved. I wonder where the difference lies with yours? (Jase put a stage 2 in mine because I’m a nice guy 
hyea: ) and there are no downsides for me :2thumbs:

Yes, this is important. You have to go through the full throttle range to red line.

Does anyone know how the ECO button affects the flash. I turned the Eco off on mine the day I bought it & it hasn’t been on since. I don’t even want to turn it back on with the flash to see what it does. Just curious if anyone knows. If it gives you ludicrous speed I might try it.

It won't do anything for you power/speed wise. It is only there to "supposedly" increase fuel economy by prompting you to shift sooner (more economical rpm) and possibly retarding the timing some but I'm not 100% on the that...

IMHO " ECO mode " does change the MAP somewhat ….. If I have MY OEM 2014 RT in " eco " mode, it isn't as responsive ( and this has nothing to do with the shift lights )….. I think it does this via a slight RETARDING of the spark …. how this might relate to an ECU Flash I won't speculate on …. maybe Steve can enlighten us :clap:...……………...Mike

Not sure about all the things that happen when ECO mode is engaged on the Spyder. I do know that BRP does a great job changing the performance of their vehicles electronically. I owned a Can Am Commander (4WD) for several years. It came with 2 keys. One was "standard" and the other was "performance". A very noticable difference of operation between the two. In addition, there was an electronically operated switch that changed other operational peramaters from "normal" to "sport" mode. One would think that you might want to keep the vehicle in sport mode with the performance key in all the time. That gave the highest level of power, speed, and responsiveness. Most times rock crawling required reducing responsiveness electronically to eliminate jerkiness of throttle caused by (me) bouncing around. Very effective. I highly suspect our ECO mode on the Spyder does more than just tell us when to shift. I tried it a couple of time just for kicks but haven't used it for a long time. I just know that BRP does know how to alter performance with more than just lights telling us when to shift gears..... It would be interesting to know how and what is effected in the ECO mode when the ECU is flashed..... Jim

My statement about power/speed was in response to the OP asking if it would give him "ludicrous speed or something". I wasn't saying that it didn't alter the MAP or that it only prompted for earlier shifting. In fact, besides the timing it may alter the fuel tables and throttle behavior as well.... At this point all I know is ECO is worthless and just basically a PITA to me! :roflblack:

400 miles later and...........it’s a lot better. Went for a long ride today, in all different kinds of terrain (so to speak). Everything from slow twistys, to cruising through the mountains, to freeway speed 75-80mph and even up to 115 on a nice open & empty road. It has improved over stock. Definitely more power. Like everyone says...this is how it should be from the factory. Mileage both times I filled up were 31.5 & that’s what it was before flash as well. Pulls much better through the gears & seems to shift more positive (shifts like you are not using a clutch, no lag). One thing is though, it’s a lot louder. More low rumble & drone if you are below 4500. Don’t know how or why that is, but that’s what I noticed. I’ll probably be adding a baffle to my cat delete, for that reason & also it didn’t improve my loss of low end from when I installed the cat delete. All in all I’m happy now. Fans do seem to run a bit more too now. I was only in 70-75 degree weather too. Can’t imagine when it gets 100 out.

great to hear..it needed some time to settle in...about your cat delete...what brand are you using?

I've had my flash for about 7 months now and I'm very happy with the difference. The exhaust on mine is stock but I have noticed at idle it has more of a rumble to it and a little louder. When you get on it, it has a nice growl as well. Throttle response is much better and requires less twist of the wrist. Unfortunately now at 9500 miles my rear tire is shot. You can feel it break loose much easier now. Mileage wise, pretty much the same as before I had it flashed. Although, I do tend to hot rod it more. At cruise at 75 mph (by GPS) 78 indicated, I can roll on the throttle and easily be hitting 85-90 in a couple of seconds. To me, it was a good investment to get the improved performance.

I’m running the lamonster cat delete. I’m thinking about taking out the can opener baffle & installing a Khrome Werks. It’s the only thing I can find that will fit besides having one custom made.

You may want to look at the RLS with an additional baffle.
It's way better...Hypurone and Dennis in Lodi runs that on theirs with great success... I also run that setup on mine...make sure you order it with TWO baffles.

I paid $300 for the cat delete & not really wanting to spend a bunch more on something I may not like. It’s only $30 for 1 baffle, so I’m going to try that first

Was out this AM and on my way home I stopped to see if I could help a motorcycliest on the side of the freeway. I didn't have my jumper battery with me so I was off. This was the first time I pinned the throttle since the ECU flash and--- it's worth every $ you spend on it. Was easily up to freeway speeds in a couple of seconds. Pulled hard to 7,000 RPM or so. ( I really wasn't looking ) Better than before fore sure.

i have been out today testing maptunerx stage 2 flash on my f3s daytona with 79 tooth sprocket took about 15 minutes to install.tune only effects sport mode so its easy to switch between stock and stage 2 tune to compare. throttle response is more linear right up to the rev limiter no more bogging down above 6000 rpm and below 2500 rpm as soon as you enter sport mode you can hear the engine tone change after coming back from a 200 mile ride to let the ecu build the fuel tables i did 2 runs on the same road in different directions stock top speed on gps 125.6 mph maptunerx stage 2 top speed on gps 136.8 before i had to slow down for traffic i need to find a better clear police free road but there getting rare in these parts now. she was still pulling strong when i had to slow down so i think more testing is needed. very happy with the maptunerx tune plus i can read and clear error codes and reset ecu history if i need warranty work doing:yes:
