YEC is Yamahas own dedicated "in-house" race department.Īs for the software, this is also a cloned copy of YEC software. YEC is a very different beast compared to a standard ecu. Unlike any of the other flashes, a YEC flash does not retain any of the standard ecu 's all different. The reason you have to send your ecu is because HE is the only person that can reprogram the ecu from standard to YEC. This allows you to program the ecu from your computer. I bought a pre-flashed ecu and kept my original. In other words, price and range of vehicles is NOT correlated to knowledge base about a specific package, just that the ability to crack the stock code, find the parameters you wish to manipulate, and a reliable range of values to change said values to.general knowledge about tuning is a given on each bike once you've reached this level.Click to expand.The ebay guy can send you back your own ecu.just takes longer.Įxchange ecus can be delivered within a few days, depending on where it has to be sent. That may be fine for most of you, but I know I wouldn't want to take that chance knowing i could have a bike running at 13-13.2 but is instead running at 14 or 12.4.ģ) The pricetag for flashing is in the R+D it took to CRACK the ECU's/ECM's coding, NOT the R+D it took to "lean about the specifics of the engine's performance based on the ECU parameters you modify". 5-.8 AFR values throughout the rpm/power band.). These are all things that, in my experience with cars that have THE EXACT SAME MODIFICATIONS, make a big difference (as much as. Accounting for things like elevation, temperature, individual engine performance, best power vs tuning for AFR, etc. Wouldn't ECUnleashed have posted up the AFR's on their dyno's as an additional selling point if they were good?Īfter dealing with the canned flashing industry from the car realm (especially the Hyundai Genesis, RX-8, and Subie crowd) I've realized a few things.ġ) Not all flashes/flashing companies are equal, some can only manipulate certain variables in the ECU, some are too afraid to, and some just want easy money for doing next to no changes.Ģ) A flash has NOTHING on an individualized tune, it is only a half-solution to a standalone ECU or lesser device that has the ability to manipulate the same variables. Often times when you ask for too much information, it kills the marketing/advertising schema. To us this said a lot about their knowledge into ECU's Here is the list of the flashes ECUnleashed currently has. So far sport rider has done a lot of testing on ECUnleashed as well with very good results form the fz1 to the 2011 zx10. You can get into an ECU but if you can't crack every component then your flash won't be as good as someone elses. This type of things goes to show that not all flashes are the same. They have flashes for the kawi's, but at this time they can't remove the cel's. Some they are even still working on like the cel's for the kawi's. Here is a list of the current bikes they have been able to crack the ecu of and then build a full map for. We went with ECUnleashed as their knowledge seemed leap years ahead of others based on the fact they tune snowmobiles, high end exotic cars, motorcycles, etc. The same as you would compare engine builders or suspension tuners without opening up everything they did and redoing it yourself. which leaves dealers, riders, every other joe with comparing their experience, who uses them, compare their knowledge based on how many applications they can flash, write up mags, etc. I'm not saying one sucks or which is hands down better as the only way to do that would be to open both files up and compare, but if you're not one hell of an engineer and break their encrypting then you can't. Just because someone can tune suspension or build a block doesn't mean it's the same as the next guy who can. Just like building an engine or suspension. It comes down to knowledge, experience, etc. exe fiels doesn't mean what is inside the files is the same or does the same thing. Like computer software, just because you install two. You can flash for just fuel or you can flash for 20+ other things if you have the knowledge, then you need to have the knowledge on what data to replace it with once you figure out how to flash it. Each company has their own flash for all the different specs that they can, or have the ability, to crack.
