- There are a lot of CRF 250 rally mods on the market to increase power, but upgrading the ECU could be one of the easiest ways to get power. We built a custom map for our CRF 250 Rally and it has to be one of the best mods we have done

Dave Wood OMG what a hero
He's everybody's hero 💪🏻😎
Almost at the power to weight ratio of a BSA Bantam there chaps😆
The bantam would still edge it #savagepower
Impressive results would you expect to see the same 10% gains on a stock 300L following the same process
I see no reason why not, Chris. We've not investigated that avenue though....yet 😎
Hi:) What is your experience after the 5 months?
saw fat boy slim going into light autos there , bit of a worry lol 🙂
I ride the CRF250Rally with the ECO=SHOP ECU, stock exhaust and no airbox mod.
I would be interested to know what settings you found out on the test bench.

Great improvements and very interesting. I'm in the market for a CRF 250 or 300. If you started again from this moment in time, would you buy a newer 300 or a second hand 250 for quite a saving then use the spare money for modifications? Given the improvements on the 300, is it worth the price difference for a better base to begin?? All the best, Tim
Hi, I have a ECU-SHOP.. Can you say the parameters that you use?
Wow! Great stuff. Any idea on whether fuel economy is impacted?
Hey, we're still testing that (more to come after the weekend), but it appears to be negligible 😎👌🏻
Any plans on another ECU tune with an after market exhaust?
Got to admit, that's unlikely. Never say never etc, but a stock exhaust fits our needs for travel, so that's how we tuned it. Woody did say there were bigger gains to be made with a full system as well as the ECU 😎
I have also seen on sale some tuned ecu from 550 Performance, do you recommend that?
Hey Guys that’s really impressive! 10% is a fantastic gain. Could I ask how you feel about the reliability of the new ECU plus are you concerned about engine life/wear?
Thanks Ian, we were well impressed with the improvements. We can't say regards reliability yet. Tye ecu hardware will have to be tested over time. It appears robust, but 🤷🏻♂️. We're not concerned regards engine wear tbh. The safety margin built in at the factory is huge and I doubt we have come close to worrying the engine. Of course, time will tell.
Good luck guys I really hope it works out! If it does you can make a packet 👍😁
Any update on this please?
@@lightweightadvAny updates on this?
Hi guys, any update on how to get hold of this ECU??
Hi Mike, unfortunately we are not going to be moving forward with this, we just can’t get it programmed to a state where we are fully happy to promote it. We have managed to get better performance from the bike but there is a cold start issue that we haven’t been able to rectify unfortunately. It is fully programmable and you may have more luck than us, I can give you the details of where we got it from if you would like?
@@lightweightadv Yes please do let me know where it's from. On balance is it worth installing? And is it ok with stock exhaust?
What is the adress to the seller and what is the settings?
Will this be a be a mod that can be bought remotely, ie now the development is done, it can be sold and just plugged in to the bike by the owner? Or will every one require dyno tuned afterwards? Thanks and interesting vid.
Hey Gazguzzler, nope, when the testing is done, the ecu will be a plug and play, providing your bike is in the same configuration to Marc's, ie airbox mod done and stock exhaust. If any of these are changed, a retune on a dyno would be required 😎
Don't you need to change the exhaust for these mods?
Your don't need to, but it wouod have added another step in performance
@@lightweightadv I thought it would damage the bike, because the air and fuel mix is changed, I watched another video where a guy removed the little part on the end of the exhaust for 1 more horse power and someone said it is not good for the bike
Take the spark arrest out is not going offroad .
While it looks like a win I can't help wondering what the cost of the Dyno time and ECU came to in hard cash .
It wasn't so bad tbh. We worked with someone who saw the project rye same as us so dyno time was acceptable. The cost of the ecu and map should only be around £300. That's not bad value in my mind 🤷🏻♂️
I totally get what your doing here and fair play . I just wonder if the average owner will stump it up .
So just out of curiosity, is the 250 pulling better than a 300 or the same?
the 300 pulls better. way better.
When we tested the 300 alongside the 250 in a real world test, the 300did pull better, but not way better. It's a larger engine and lower geared in 1-3, so that's a pretty conclusive result, but the 250 is still a great bike and you wouldn't go wrong with one.

@@lightweightadv Thanks i'm at 46000 km's now with my 250 Rally, my buddies riding modified 300 Rally's but hej there's always the guy with the better bike, thanks for reply, have fun on the 250!
But i find the 300 runs out of revs pretty quick, where the 250 you can rev it too the moon on the 300 you have to keep on shifting because of the longstroke engine character.
Question; does this mod use more fuel? Would love to have a bit more power but I also bought the bike for the low fuel conspumption.
Hi, there may well be a change to fuel consumption as the fuel and air mix etc was adjusted by Woody to get the gains you see, but truth be told we think it will probably be negligible, however without testing it we don't fully know for sure. This may well be one of the things we check when we throw the bike at some lanes 👍
@@lightweightadv Thanks! keep us in the loop if possible and enjoy the ride!
It’s likely to be more economical on the cruise, as the ignition timing has now been optimised, but there’s a good chance that this will be masked by the lads pinning because it’s fun as they did with my airbox mod. On the cruise the airbox mod is also as good if not better on fuel.
So on the final result, you only changed the ecu and everything else is stock? Would love to know about mileage changes also. Thanks
Hi, so the total gains were made with a combination of new ECU and the airbox mod, when combined these give a great improvement and is what we will be running from now on 👍
All of the Dyno wizardry is cumulative, each part builds on the other elements fuel, air, exhaust, ECU etc etc, we were aiming for low end torque gains combined with respectable noise levels, hence standard exhaust. We will probably try to test mpg in an upcoming vid when we put it through its paces in the real world ut I don't envisage huge differences with fuel tbh 👍
@@lightweightadv nice. Thanks for the feedback!
I really like your content but i don´t understand why you are making such a secret which ECU is used. If you search the Inet you will find it very easy. The only available programmable ECU from Thailand (besides APITech) is the Full Stand Next ECU which has been used here (at least it looks very similar, please correct me if i´m wrong).
Don´t misunderstand me: I appreciate your work setting up the CRF with this ECU, results are promissing.
Is there a plan to do another shot with the dynojet power vision 3? It´s also similar to use but flashes the standard ECU instead of replacement. I´m tempted to buy and use the PV3 on my Rally but there is not much experience with it yet out there. Full Stand Next or Power Vision 3....??
Hey, thanks for the comment. We're just working on a few bits with this, and so we're not wanting to tell half a story. We'll tell everything in a few weeks!
@@lightweightadv Thank you for the fast reply. I look confident for new promising content about this in the next weeks :-)
Which ecu are you using?
A part number or link for the ECU would be really helpful.
Hey Matthew, we haven't bought from a shop etc, we have a contact out there who ships to us. We then put a custom map on to them (they're not set up prior). If you're interested in getting an ecu, email us at Lightweightadv@gmail.com and we can help 👊🏻😎
it's a full stand from ecushop in thailand. i run one on my grom, it's a pretty decent ecu for the price but you'll have to learn to tune yourself
Yeah, that's where we got the basic ecu from. Not awful straight away, but we then got a custom map built, now it's 🔥
@@lightweightadv yeah the basemap they come with isn't the best, i've had to do quite a bit of changes for my stock grom (only aftermarket exhaust) just to get it running right and making good power.
Just switch to 300s boys, you wont regret it
Hey, thanks for the comment. I've no doubt the 300 is a great bike, but I just can't justify the £3k it would take me to upgrade. Especially given we have molded these bikes into our own individual needs. This makes the power specs near enough for a fraction of the costs 😎
I've been known to bend swingarms will pass
Hi guys, I sent you an email about this as I'm interested to get one....had no reply which is ok but can you check your spam please? Does your email start with capital L? Thanks, Mike Jones.
Hey Mike, just seen it, thanks. We'll get back you to soon 😎
@@lightweightadv Thanks guys. Any idea when? 😀
@@lightweightadv Any idea when you will get back to me? I'd really love to fit an eco to my 250. Thanks, Mike.
I have just sent another mail, please check and revert, thx.
If you want more information on the ecu and how to get one, email us at: Lightweightadv@gmail.com
Any plans to have ECU'S for the 300 ?
Hey Jeffrey, we'll finish the 250 project and then see where we stand. I think bringing the 300 along would be a lot faster if we can source the hardware 😎
How often do you check your inbox? I'm keen to know more about the ECU, emailed you a few days ago.
We check the airbox only once in a while. When Marc did the mod, it was checked frequently, with zero debris found. Now, they get checked every couple of thousand miles, no issues yet
@@lightweightadv Your EMail inbox. I have inquired about the ECU as you suggested at the top comment.
