I have a 2012 yfz450r with MSD, hotcams stage 3 intake cam, full Lone star exhaust, stock intake with K&N open filter no lid. I have velocity intake not installed which will be going soon. Seems to run rich. Does anyone have any tunes or suggestions? Thank you.
Hi Im kinda new to creating tunes with the blaster fi. I will be moving to an area with average elevations of around 5000' that can range to 10,000' with temperatures from the 50s in winter to around 100-110 in the summer. I have a full system gytr exhaust and a stock airbox with lid removed. It doesnt have to be perfect but id like it to run like it should. Also if anybody has a tune for around 300' elevation id be interested in that as well. Im interested in learning what changes to make to tunes to modify them for different elevations. I understand what im doing with carbs but I have no idea what fi values to change or how agressivley i change the values.
Picked up an MSD for my 2010 with full race ported head, slip on exhaust, FCI intake, 2004 yfz intake cam, 2014 crank, running 500-1000ft above sea level. anyone have a map handy? I have started fooling around tuning it and it runs great, just not too sure on how much fuel to add where. the only real issue I am seeing is burbling after decel when getting back on the gas. I have no bog at all and the midrange is great.
I have been running the first map from ironside17s on page 23 and its working great so far.
also, I seem to be having difficulty getting the "notes" page to stay updated. every time I make a change, it immediately reverts back to default settings. I also cannot get the green to highlight the active cell on the fuel page while the quad is running.
So I've been playing with the blaster to try and get the bike running as close to perfect as I can and I noticed something. First a little background, I'm a 30 year auto tech who's built and owned many race cars and hot rods so I know how to tune an engine. Anyhow, I notice that just off idle at say between 2 and 3K rpm with 5% or less TPS the thing pull out crazy timing creating a bog. I have it setup so it's super responsive with no bog at all when you hit the throttle like you mean it, or anything above 10% really but Yamaha has some hokey shit going on in their tune. I can add a bunch of timing with the MSD there but it's too high at idle to make it where it needs to be when you open the throttle slightly, there's no real load on the enging here so it makes no sense for a factory timing curve to do that and there's nothing in the MSD to correct it. Shit like that frustrates me to no end, it may have something to do with the EPA to reduce NoX. Don't get me started on the EPA getting their bugger pickers on recreational vehicles...
Anyhow, I found a pretty happy medium that makes the bike feel so much better just putting through a trail if anyone wants to try it out. It's basically just a modded 5 degree timing map with extra to help out with the off idle flat spot. Looks like I have to go make 5 posts before I can post a file or even a link to a screenshot
Hello everyone, new to the thread and im gunna need some help with my msd when i eventually get it next week. I just bought a 2018 yfz450 and will be installing a fci intake and GYTR ais delete. For right now i have the stock exhaust with the spark arrestor out but will eventually buy a yoshi rs2 in a month or two. Thank you.
So after installing a full yoshi rs2 and fci intake with airbox, I have tried about 5 maps from this thread and i cant seem to find one that works well at all. High idle at times, stalls, bogs off idle, stalls off idle. I really need help there is absolutely no one that i know who has any knowledge about this sorta thing so please i need your help.
