Is My MT09 Stock or Remapped? A Day at BHPUK!

Hinzugefügt: 2026-05-05

[00:00:00][music] [music] [music] [music] [music] [music] >> Tell BHP UK and we are absolutely privileged to be joined by Jake at JBL again and he's back on the scene with an MT-09 and I'm going to let him tell you a little bit more about it.

[00:00:46]>> at BHP today. Reason being, I bought this 2018 MT-09 and it's got a full decat Akrapovic racing line exhaust on it. As I mentioned before, I've had a 18 plate Yamaha before and the fueling on that one was horrendous. I've jumped on this one and it seems to be okay through the throttle and feel around the roads.

[00:01:05]So basically we're down here today at BHP to get the answer, is the MT-09 being remapped?

[00:01:10]>> Well, let's run it up on the dyno. We've got lots of data from stock MT-09. Mhm.

[00:01:15]Uh we'll run it up on the on the dyno, see what power it's making, see what the fueling's doing. We'll do the the the full set of runs there 50, 75, and 100% acceleration runs. We'll do them in mode A. It gives us good comparability Stronger. with the bikes. Yeah, we tend to run all the the Yamahas in mode A when they're here. Means we can compare them for situations like this.

[00:01:32]Uh we'll see what it's doing. As you quite rightly pointed out, we can run it in fifth and sixth to see if the limiters have been removed. So we'll do that, see what it's doing and then we'll make a decision as to whether it's been mapped or not. So you feel that it's not quite as it should be, but it's not quite also as a standard doesn't feel like a standard bike. It more feels to me cuz I've only ridden two of this exact model. It just feels smoother in that top mode than it did with the stock exhaust. It was it was basically unridable with the the stock can and that's ridable in A mode.

[00:01:57]>> Let's see. Let's see what it's like and then we'll get it if it's not mapped we'll put the map on it. Yep. Uh see what the difference is. If anything's mapped, happy days. Let's go.

[00:03:06]140.

[00:03:08]Nearly mapped.

[00:03:12]I come on, put it up there.

[00:03:15]Right, so that is >> [music] >> a stock bike, yours. Yep. Is the blue one compared to a stock bike that we've had in before.

[00:03:24]Uh >> [snorts] >> uh I like quick healing them.

[00:03:31]>> [laughter] >> Fueling is about the same. Right.

[00:03:34]So it's down to a touch really, isn't I don't know. I don't think so. 40. Yours is a touch richer higher up in the in the throttle positions.

[00:03:44]But anyway, he's a richer he's the bottom end where you want to. I remember last time you were saying with that bottom graph you want it as close that line as possible. Or thereabouts, yeah.

[00:03:51]Yeah. Yeah. Has it got the restrictors still on it in fifth and sixth? They they they do have restrictors. Oh, actually let's check that out. Yeah, that's what I thought. That's something I forgot to ask you cuz you that's how you can usually tell with these if you've been on it cuz they just take them straight off. It's a speed limiter, isn't it? It comes in.

[00:04:05]>> Yeah, it's just a don't let you hit the limiter in sixth or fifth I don't think.

[00:04:09]I don't know.

[00:04:11]>> [music] >> So that's the runs done on your bike. It isn't actually mapped at the moment.

[00:05:00]That were a big shock to me to be fair that. From how it felt on the road, big shock. I I was expecting it to have been mapped, but like you said fully fully mapped. It just [music] I can't believe it's not mapped for how it felt. So if if if we if we remap it must feel awesome. I mean we can tell it's not mapped because at 25% accelerator position it's just running stock as it were. You've got a massive lean spot up to about 7,000 RPM. The fueling looks stock everywhere else and of course it's still limited in the power in fifth.

[00:05:26]That was the main one, wasn't it? The Was it a speed limiter It's a speed limiter, yeah. Yeah.

[00:05:31]Why do they do that on such a capable bike? Just stops you getting over whatever the speed limit is. I've forgotten off the top of my head now.

[00:05:37]But it doesn't That's what I mean. It does but it doesn't limit you at 70, does it? It limits you at What what does it speed does it limit you at? 150.

[00:05:43]Yeah, exactly. You know what Let's stop him from doing 150 by letting him do 140.

[00:05:48]But yeah, it's in fifth and sixth you hit the speed limiter before you hit the rev limiter which is why it dies off at that point.

[00:05:55]>> So it's not an engine saving No. Right, it's just purely a safety thing. It's just a just a speed limiter. Wow.

[00:06:01]And all the guys are already writing the map as we speak. I'll let them finish the map off, we'll get it back on the on the on the bike and then run it up again, see what the difference actually is. Awesome. Look forward to it.

[00:06:20]Right, so bike's done. We've got the fueling right exactly where we want it Yeah. at every point in the throttle curve and in the RPM range.

[00:06:31]>> [music] >> The we've removed the speed limiter, we've removed some of the restrictions on the throttle and we've tweaked everything else that needs tweaking on it. Perfect. Uh so we'll get it off the dyno and you can go out have a ride on it and let us know what you think.

[00:06:43]>> Carl and the guys have done the 790 I had.

[00:06:46]I think even I can remember the figures on that. I think it were 97 to 105 I think you got up to that. And that felt totally different. They're restricted.

[00:06:53]They're restricted in fifth. Are they restricted as well? So yeah, we'll see how this one goes, but Yeah, I think we've gone from 114 to 180. Yeah. Well, just short of 190. So a a usable [music] gain of five brake horsepower. But we're seeing it a lot of it was that low end The low end stuff is the the fueling at the bottom end is really what's going to be tangible and usable.

[00:07:10]>> Which is where you use it on the road, isn't it? 90% of the time, so Right, let's get it off, let's get you on the road and keep us posted. Thank you. Nice to meet you again, Jake.

[00:07:19]>> Yeah, you too, man. Thank you.

[00:07:21]Right folks, well that is us wrapped up at BHP UK. A big big thank you to Carl, Dave, Luigi, and the team for inviting me down and having a little look at this uh beautiful MT-09. I'm sure on if you head over to BHP's YouTube channel, you will see them all in-depth stuff um about the bike and the sensors and all the the really smart people jargon that I try my best to understand, but I really can't do it.

[00:07:50]Um well it's been a couple days since we uh since we got the remap done at BHP.

[00:08:00]Yoohoo.

[00:08:05]It's been a couple days since we got the remap done. It is Friday now. Um we got the remap done on Monday. And yeah, the reason I'm sort of filming this little segment here is on the way out of BHP I had some camera issues. I kind of forgot to make this camera back to ultra wide. From the guy who's just made a how to motovlog series, I told you I still make mistakes. Anyway, by the time you see this video their video will be already be live. So I'll leave a video to their channel as well in the description below. So go check out their longer version rendition and they might have a little bit of a podcast segment we filmed as well. So I'm basically now just out on a little ride because it's been raining all week and I haven't really had time or chance to to test the map. They messaged me when I got home, but I had to take the um the motorway home, so I never got to really take it on some nice roads. Today is not the greatest of days. It's I don't know, 9° overcast, a typical British day. But the roads are dry, the salt's disappeared and I thought now is the time to have a little play around with the the remap 209.

[00:09:11]Oh, there's just definitely a difference.

[00:09:19]Just how connected you feel to throttle, man. So this segment of the video isn't going to be a sort of a review or how does it feel different. I think what I'm going to do is get a couple couple hundred, maybe 2,000 miles into my belt really with the bike being different and and make a separate video talking about that, talking about the economy, the throttle feel, the different riding conditions and stuff.

[00:09:40]Already I can feel the difference. There is a big difference, but I won't mention it in this video.

[00:09:46]Um but yeah, I'm just heading up to some old local roads. They're not local anymore.

[00:09:52]Um where I used to do a lot like the pure sound videos and a little bit of a stretch where it's quite quiet. But yeah, that's pretty much it from me.

[00:09:59]Thank you to the team again.

[00:10:02]And uh thank you very much for watching.

[00:10:04]Just enjoy some some nice MT-09 sounds on some twisty roads.

[00:10:13]Enjoy.
