evo ecu flash

[ishpeming fan]

I have a 2014 viper ltx. I have had the second reflash done that came out in 2015 and didnt notice any change except that sometimes it takes two cranks to start instead of one. Does yamaha charge us for the most current flash if the sled is no longer under warranty? I am also wondering if anybody has the Evo reflash done with 87 octane and can option that they offer for 550.00. and if so what gaines did you see? they say it changes to more rpms so you wont hit the rev limiter until around 9800 rpms or so. this also means that you would have to remove some tip weight to clutch to gain more rpms as the goal was around 9100 rpms correct?Also does the evo ecu reprograming take care of the start issues? anyone that has had the evo flash please let me know if it is worth the money thanks

I have evo flash and it is starting quicker and more solid, havnt had any kick back at all with the evo flash yet.

Did you get any seat of the pants performance gain with the evo flash?

I have the premium fuel EVO flash and there is a noticeable improvement in throttle response which I can feel when I ride.
The raised rev limiter makes clutching a little easier as well. Because then I'm not bouncing off the rev limiter if I happen to be a little to light in the primary weight or if I drop down in elevation while riding.
I did have them set the rev limiter to 9400 RPM which is where the Nytro limiter is set at instead of 9800 RPM though.

ok thanks for the input.

I cant speak for the 87 octane flash that your looking at.
I have the flash for 91 octane, header, can and intake mod. My sled definately starts and runs better with evo reflash.
Better pull through entire rpm range. Noticably quicker, i gained some, but did not gain a lot on top end.
Starting is a non issue. Always starts good no matter what the temp is and does not kick back ever.
I would buy it again

Here is what I don't understand about their flashes. They claim the motor likes to rev and makes power past the rev limiter of 9200 rpm, but when ever theses motors are put on a dyno, whether it's a Nytro or a Viper, power usually peaks at 88-8900 rpm and then drops off. So how is it that the motor all of a sudden makes power above 9200?

My Nytro with a free flowing exhaust makes peak power to 9200 rpm and then drops off, I've seen it on the dyno, so again, how do they find HP over the rev limiter when Yamaha built this motor to make power up to 88/8900? I think they have a magic dyno lol, cause every other 1050 motor has only ever made power to 88-8900 on every dyno except theirs. Add a full exhaust system and power still drops off below the factory rev limiter....I'd personally like EVO to explain it.

Even if power is way up in rpm good luck getting it past the clutches. Higher rpm of clutches the less efficient they become. That's why many including me have done everything possible to find power lower in rpm. Wish the gear reduction was on this motor. Then we could rev them way up and harness every bit of power.

IMO, from my testing over the past 7 years on this motor....full exhaust, airbox mod, tune it and clutch for 9000 and enjoy

yes that is what my concern is that I have An Ulmer clutch kit and machined secondary by Allen he he said dont go above the 9000 ish range for best power. I put a MBRP trail can on it and it was turning around 9350 rpms so I put tip weight on and now back down to 8900ish rpm with the apex belt and the thing struggles to get past 90 mph on decent conditions and around 85ish when there is a little loose snow on top of trail. Thats why I was thinking the evo flash would speed it up some. But I dont want to waste 569.00 bucks on a flash if it wont give me a little more top end. I also dropped two teeth on lower gear so I could utilize my stock chain as well because new chains are another 150-200 bucks. Also the preium flash adds to the bottom line every time your at the pump so I was just checking to see what other vipers gained by the flash. non turbo.. Also do you know if Yamaha charges for their most updated flash if the warranty is up? it still doesnt make sense to me to add higher rpms either when everybody else says around 9000 is the target

One thing I don't get about the Viper is why they are so inconsistent with speeds...the Nytro was similar but most seemed to hit 100 mph regularly. Add full bolt ons and still a 100mph sled but it gets there so much quicker.

My buddy did the full Hurricane kit on his 14 LTX ( full Hindle exhaust, airbox mod, pc5 and clutching ) and said he was consistently running 100 mph in most conditions. IMO I would add some type of airbox mod to help with the exhaust mod..I'd do that before I changed my ECU, if your gonna exhale you should let it inhale as well....they seem to go hand in hand.

I can't say you won't gain top end with the flash, but I still question the fact they are the only tuner that says the 1050 makes HP over 9000

I would have to say due to lack of response. No documentation. If topend is what you are looking for look elsewhere. Now as far as starting,kickbacks and smoother idle there does seem to be agreement that the Evo flash works better than the factory flashes.

As for the Nytro everyone I have checked the speedo was at least 8mph off so if your seeing 100mph consistently then its 92 Viper mph. Pretty close to average Viper with minor mods. They all feel faster till they are raced side by side. Then those feelings get hurt.

I did look elsewhere 400 clutch kit,, 65.00 machined secondary, 75.00 two teeth taller gear, 200.00 can , approx 4 to 5 mph more top end speed. thats over 100.00 per mph.

My Nytro with mediocre clutching ( revving 9300 ) runs 101 mph on radar in 1000'.....speedo reads the same, maybe a tad higher but not 8mph higher

I would go with an airbox mod first... dyno proven, whether it's Ulmer, Excells or whoever else's....they make good gains on the Viper....cheaper than a flash too.

Yeah I think I will do the airbox mod and see If I gain any top end from that. The powerband is nice and meaty on low and midrange but a few more mph would be nice.
