Why dont vendors do custom tunes

[Sledbrapping88]

Hello every one just curious of why no one has mention to any of our vendors about custom tune. I'm not talking about just performance adder cai exhaust etc. I'm talking real custom tune where your tune sends base file for your setup area you ride in and how you ride fuels and weather take place in this so say for example hurricane 240r to start with bc you have exhaust,cai,bov. So instead of just sending one tune you would go out and ride very mild at first to see how your sled is running while recording datalogs of afr boost timing etc. Then say you do a few power pulls while data logging from a roll to top end . Then you would have led take your data logs send then to your vendor of whom you chose. From there they would look at data log threw email and make adjustment on mapping to turn things up like boost,fuel,timing, work on spool time etc. This would be a big factor for adjusting customers throttle reaction and clutching of the wants and needs of the sled performance they are looking for. So this will go on many times of you taking data logs while riding and perfomance pull etc and sending them to your vendor until you and your tuner are happy with performance driveability and clean data logs for your setup. So the benefit of this not everyone rides the same as far as people reaction time they way ride or what type of riding they do. So results would for personal custom tune better throttle response tuned for your reaction not just the sled. Better powerband for your style of riding. Better fuel mileage and reliability for your area of riding choice and what octane you used. Also we cant forget more power because your tune is adjusted perfectly for your setup and area/octane. So some you guys that are tuned already tell me if you think you would benefit from this I know from my golf r base tune to custom tune what huge difference every where and both base and custom were for same performance parts and rider weight and tire size. So my tuner personalized my tune for my my needs.

All things are possible but there’s a cost to make a perfect tune a custom tune. It can be time consuming

Yah it took like 3 weeks for car to get its final revision tune but for the serious customers it would be worth it

Sounds like Hurricane Dave is your man! give him a shout !

As Dave said anything can be done. But if you want that level of customization a full stand alone ecu would be your best option if you had the ability and know how to tune it yourself. Eliminate the waiting for files back and forth. Then you can do multiple changes and testing in the field with real same day changes and evaluations of data logging. Otherwise stick with the very reliable "premade " tune selections from the great vendors on the site.

Yah but I'm not a pro racer so that's out the question on swapping ecu etc and doing same day changes would benefit for that day only my trails change every hour during the season.
Another thing to think about is not every sled is the same some are little better some are worse I dont think you understood what I was trying to get at on my post I'm talking overall a better tune for every situation you ride in which is why its custom tune for my riding style and area daily condition changes etc. Not evryone wants to make changes every day maybe racers or one in while when you have a competition day with buddies or event but not for every day joe

I dont think you are understanding the abilities of a fully standalone ecu vs the hassle of what your asking for with an ecu custom tune. With the option for multiple upon multiple sensors and inputs you can create multiple maps yourself for your different riding areas or conditions or days. Or you can have the map automatically adjust based on air intake temps, ambient temps, barometric pressures etc to always be getting the most out of the tune up.

As you said even your daily conditions will change which means you'll never have a perfect tune for every condition all in one with a pre programmed tune. You can have so many more compensation tables of your choosing in a standalone ecu to get what you're looking for then after it's set you'll be good to go. Limited need to tune again untill you change areas or riding styles. You can change maps based on ethanol or non ethanol fuel which noticeably changes afr readings, possibilities are endless.
Or you can spend as much or likely more getting multiple revisions for a tuner and you may wait weeks per revision. Mid season they are likely way too busy making sales to spend time custom tuning for 1 customer .

Or just get the premade tunes that are damn good and close enough that most will never notice the difference between them and go ride. Set your clutching and gearing to your riding style to compliment the existing tune. Much simpler than trying to rewrite an entire tune that they cant field test vs you field testing your own clutching/suspension/gearing changes for your style.
Just getting back to your point of your trails changing every hour the only way you'll compensate for that is with a standalone. A custom tune for your sled is still a one time deal that wont be able to adjust for those constantly changing conditions any better than one of their existing tunes of which they already offer a dozen plus variations probably for power/muffler/accessories etc

Coming from that past world of piggy back systems and the need for all the precautionary gauges that went with them, (AFR, Boost, etc) and also the very real need of keeping an eye on your stock gauges for info( RPM, Speedo, and many many other,) now included in these stock machines, and for myself, watching what these vendors have done since their first 2017 versions, to include my favs, knock light and boost gauge on the stock cluster, not to mention multiple maps and much much more.
Well just let me say, I got exactly what I wanted with a simplistic tune that provides all the power that I need and knock protection against bad fuel or my white knuckle long WOT runs, time after time. And if I do want to watch or see how many lbs of boost my Winder is putting out, there it is on my cluster, but for safety with the way I ride, usually rpm and speed is my main concern. But then again, I am just a trail rider/racer like most on here!

But for guys like you that really have that racers need of pushing the envelope of ( hp, clutching, gearing, traction, etc) for the many snow conditions faced in a season! Please keep it up and share your findings so that we can all benefit from your need and expensive research! Many on this site have already done just that, Thanks all!

The tunes combined the the engine management system that Yamaha brought on the sidewinder run awesome now.
No sense in trying to make copper wire out of a penny....

Well I personally haven't tried a tuned sidewinder so i cant acknowledge your experiences with vendors tunes I just thought from my personal experience with tuning cars it would be a great idea for some guys. Will be tuning my sled very soon though so time will tell if I'm satisfied if not we will see what happens. As far as changing maps in ecu from base file there is only small changes in the map that tuner would make adjustments to yes it a different map but does not take that long to adjust and send over a new revision that only has small changes like timing/ boost control , fuel etc. The guy that tuned my car has plenty of work during race season even build his own turbos and other performance parts and he usually had my next revision with in a day or two. The only reason why I mention custom tune is it's more reliable,faster,more predictable then ots tune. Some of the data logs I've seen are not pretty which I take with grain of salt because traction has huge play on how datalog looks. So I was wondering if anyone on here has a clean datalog that they could post and what tune they are using. In the datalog you should see nice smooth transition with a spike when boost comes on then then should have smooth powerband with no fluttering throughout pull.

If you want to see anything like that you'll need a racers data log from grass or ice. You won't likely get that on regular loose snow ever. Between track spin and potential even momentary belt slip etc. Very different from a car log because of the conditions we have to work with. I have piggy back tuners on trail turbos, ecu reflash and tune bundles with data logging on my trail turbo and full standalone engine management for my promod drag sled. So I've got a fair amount of experience with all 3. For trail riding the current ecu reflash tunes will be hard to beat for reliability and consistency. Tweaking from these vendors tunes with 10s of thousands of miles of customer and vendor testing and validation is when reliability goes down hill faster than it gets better.
Also unless you plan to put them in timers back to back or the dyno wether it be track or engine on your own dime you will never truly know if a revision was better. What feels better maybe be a few tenths slower or less productive when you thought for sure by the seat of the pants it was faster. I used to do the same thing back when I got started with turbos and racing sleds etc. Once I ponied up for timers and dyno time I finally saw real noticeable results that work.
Best option if you truly want every last bit out or any machine. Otherwise I think you'll be pleasantly surprised with how good these vendors tunes are once properly complimented with the clutching and setup for your riding areas.

You want a Motec setup it sounds like. Step to the plate and pay the price, otherwise you'll have a canned tune from one of the popular tuners.
