- This video is about the Brixton ECU and the fuel mapping and how we might be able to get more power, the second part is trouble shooting performance problems within the current fuelmap and more specific the Lambda sensor.

Sir, you make very good quality videos with very good instructions/explanations. I feel lucky to have found your channel
Hey Steve, Amazing !!! Thank you for the interesting info on ECU and for the illustrative vid. "Chapeau bas" respect. Keep it up ! And always waiting for more amazing stuff on Brixton... Bedankt
Thanks Hanks, More is to come.. as soon as `i have sorted out additional details, as Brixton themself are not really releasing a lot of information.
Thanks for the video!!I just got a Brixton Feldsberg yesterday!Be well!!
txs for the comments
Just got a brixton bx 125 for my girlfriend. Nice looking bike.
Your videos are great. Wish I had the knowledge and skills you have.
Thank you
Very good presentation! You have helped me understand why my Brixton 125cc has a problem with intermittent acceleration (i.e., sometimes there is a bit of torque, sometimes it is very lethargic). I suspected the ECU was the issue - or at least in that area of the electronics. The dealership/mechanics have been no help to me and seem completely uneducated in the product they sell. Perhaps the exhaust sensor is faulty, or the ECU itself. I would like to find out so it can be corrected. I have no real wish to create more HP or Torque in my Brixton, but consistent performance would be welcome. Thanks for your excellent presentation of this information - very educational for those of us who like DIY theory. Cheers, TH
My pleasure, if you have an OBD2 reader, then you can readout most of the sensors real time.... I have a vide on it and that might help
Good luck
Ben aan het rondkijken voor een 125, ik ga voor de brixton denk ik -nu ik weet dat ik zo’n technische ondersteuning kan krijgen in ‘de vloanders’ 😉 ; ook voor wasmachines 😄
Keep it up ! 👍👍👍
Wrest perfect de mine (brixton) , nog geen enkel probleem gehad behalve de pinker rechts van toen die nieuw was. Maar is opgelost onder de garantie
When people will ask me who is my god, I'm going to send them the link of this channel. Such an amazing and entertaining video, where I learned something new of my bike. Thanks a lot sir!
Wow, thank you! Thanks for the comments
@@D3Sshooter thank you for sending me back a comment! By the way, have you found a way to improve the ecu?
A true Renaissance man!
Tq for sharing tips sir
Wow, thank you for this good explanation :)
Glad it was helpful!
@D3Sshooter did you ever come up with any maps for the bx150? I think we'd all love a video on this if you did.
Thanks for the comments, I have not ..planned it for a long time and then I sold it
Awesome vid thank you very much
txs for the comments
Hi very interesting video. Informative even to someone dumb in math as me, I have a problem myself tbh. I own a Brixton 125 Sk8, and it has only 2000 km on it so far, all is fine I know cause of the big whells and tyres it is gonna be a slow bike. When I rev in with medium throttle mostly there is a hole in power between 6000-8000 Rpm. The bike stops reving smoothly for that 2k Rpm it slows down and picks up again at 8000 Rpm. This mainly happens when I run the bike on average throttle for a day or two. If I run the bike constantly on hi Rpm this shows up less often. I went on the mechanic that imports Brixton in my country (Kawasaki dealership) for my 1000km service and to check for the issue. They told me they didn't find anything, which tells me that either they are incompetent or they just didn't care enough to do a proper test ride long enough with average throttle to see it happen. What are your thoughts? Thank you in advance
That is strange, and it seems to me that one of the sensors is not picking up the right signal and hence the ECU is badly informed and does not increase the demand for fuel... This could be the gas throttle position sensor, the Lambda sensor on the exhaust, the Mass Airflow or Manifold air pressure sensor. Those would be the most obvious problem makers. Yet, that should be recorded in the ECU and show up when the error codes a read out of the ECU... Ask your dealer to read the ECU codes .... I have a video on it .. If anything is wrong with the sensors , then it will be logged.... The last thing that could be wrong is the injector solenoid . For the rest there is little that can be wrong , unless you have a faulty ECU, but that would show as well. It seems that your dealer is not really taking your issue seriously . Good luck
D3Sshooter ty for your quick answer, the bike has not the engine check light on so probablu it hasn't recorded any error. The problem occurs only when I use the bike in mid range conditions for a while, when I am using it constantly close to the higher revs that problem appears less often
@@giorgiodoe3257 bonjour ,
Le temps à passé , du coup d'où venait votre panne ?
Selon ce que j'ai compris , ce n'était pas les capteurs divers puisque vous n'avez pas d'affichage de défauts !
L'écu lui même alors ?
Je serais (peut être d'autres aussi!) Très intéressé par votre réponse !!!
Avez vous toujours votre brixton ?
Eu d'autres problèmes !
Merci beaucoup . ✌
@@christianjacquet4095 Hello Christian. I gave the Brixton to my sister. But I can tell you this. Since the Brixton was still on warranty we switched the ECU with a new one and the problem was solved. After a few months I gave it a Ride and felt something was not as it should be but was not entirely sure it was the same case or if it was just me that had not ridden the bike for so long
@@giorgiodoe3257
salut ,
Merci beaucoup pour vos réponses 👍
Et idem pour vos talent ... et de le partager ! 👏👏👏

Great video and awesome analysis! I've been looking into the same but for a Mash (similar if not equal platform), ideally we would need ignition advance control, we're you able to find info about changing the ECU maps?
Álison Fernandes i think that the mash has the same delphi ecu. Have look under the saddle there should be a block with a big greu and black connector with a MTo5 label. Ii am wotking on retracting the map and analysing it. Once i have access to the parameters i can place the bike on a dynamo bench and test the power etc while changing the map. But that is still a bit of work. Soon i will post something. Good luck with the mash
Yes, same ecu. How are you connecting to it? I've found BitBox tunning software and after reading Delphi manual, there should be a USB connector that enables you to connect using some old software called Delco PCHUD. Do you have this connector? Third link seems to be the connector.

Álison Fernandes no usb only the K-line works . The CAN is not responding as per 11 bit standard. I have my own software for the k line. Soon i will put a video up. Note that its 6 pin connector. With Can hi an lo, K. Line and the 12 v and gnd
Salut ,
Les gars .... vous êtes passionnés et passionnants !!! 👍
C'est vrai que des infos/recherches de la sorte sont si rares !!!
Merci à vous et votre talent , notre sauveur brixton !!! Tant sur sa mécanique que sa partie electrique/électronique .
Un grand bravo et des bisous pour ces secrets révélés a propos de nos montures préférées !!! ✌
Amazing video. Keep it up. May i ask from which country do you come from? Greeting from Italy
Max Niemand sure, born in South Africa, schooling in the 🇺🇸 and living as a Belgian in Belgium. Complex hey
D3Sshooter You have an interesting accent. Thats why i am asking. Lookinh forward to buy my own brixton. And of course looking forward to your next video.
@@maxniemand1279 dato che tu sei italiano posso chiederti in soldoni cosa ha fatto che non sono molto spiccato in inglese? ahaha cosa ha modificato?
Dear @D3Sshooter
I've bought a modified ECU for my brixton bx125x from Aracer and you can modify all the stats (from the quantity of gasoline going in the engine, until the backfire from the exhaust). If it could be useful for one of your future videos share you email down this comment.
Hope to hear you soon
Thanks for the info! steve@flashsplash.be
Which Aracer product name/version did you buy?
Hi, Do you think it is possible to install the 250 cc on the chassis of the 125?
Great! Thanks
Maybe it would be possible to trick the ECU through the lamba sensor by adding a small resistance ?
Guillaume Pinson that is just one sensor and yes potential that could be an offset to shift the AirFuel ratio working point into a more make believe lean mixture and hence the injection would become a bit more rich. Yet , it might work to some extent but is rather static and might cause high idle and DTC’s
I think I tricked my brixton into thinking It has low air/fuel ratio by doing a thingh not on purpose. I once took off the exhaust to repaint It, and putting It back on again I forgot a small insignificant ring that was between the cilinder and the exhaust(After the cilinder but before the lambda sensor). Of course it's much louder and explodes more, but that's because the gases go out directly from that gap. So i think that in this way the lamda sensor rilevate a low air/fuel rate and tells the ECU to give more
Great info. 👍
Glad it was helpful!
So I've been thinking : All these Chinese 125s use a copy of a suzuki gn 125 engine. What's interesting is that if you look on aliexpress for gn 125 tuning there is a 150 cc kit, different camshaft etc. Installing these would help right?
DeadlySin2606 , txs. Well that is always an option . I do know that they have a 150 for the Asian market. The problem you will face is that the ECU will need remapping. And so far i could not crack the map access. More CC and camshaft alters thr mixture quantity and timing for the injection and ignition. Without that new fuel map. It is not going to work
Hi Steve
Ik zal verder gaan in Engels, zodat anderen kunnen volgen.
Did you ever get to mapping the fuel? I wonder what for result it would give if you let the engine ran more rich. I also have a question about the chines biked. Are the brixton, bullit, mash all the same in fuel ratio and components or do you think there are small differences? Thank you for hour explanations btw!
Thanks for the comments Rob, I have sold the bike a while ago so that part was abandoned. Sorry
Hallo Steve, dus als ik het goed begrijp... kan je de Brixton sneller doen rijden als je geen rekening houdt met het milieu en de portemonnee. Als je de 'Power' op het maximum afstelt zonder een compromis te maken met de andere twee elementen. En kan dat dan eenvoudig gedaan worden? Vraag me af hoeveel meer je er zou kunnen uithalen... Grt David (vergeef me mijn slecht Engels)
SuperDivad3 ja dat kan , alleen zit ik met het probleem
Om de fuelmap in te lezem. Daar ben ik nog op zoek naar. Testen moet je doen op een dyno. Ik verwcht 10 tot 20 % meer vermogen. Ik werk nog aan de fuelmap en van zodra ik er een heb en de methode om die op te laden naar de ecu laat ik het in een video zien. Groetjes
Hi! I am still waiting for new of your vidéos on it. Especialy on the ecu and the way to increase power of the Bike. 😉 did you find out how to ? Thx and go ahead !
I mean changing the fuel map ...
Well I made some progress but `I am not there yet... one fast option is to get the 150CC cylinder / piston which is sold on the brixton in asia... BUt I am still looking to get the feulmap sorted
Hey, thanks for explanations. Did you manage to remap it?
Sorry for the late reply , as i was away for work. But thanks for the comments. I have not done it as I started some other urgent work
Hey ! Hope you alright... Did solve ECU mapping issue? I need to solve the problem to get more power to my brixton. I am looking forward from you. Best regards...
TXS and still working it...fuel maps are locked
thanks, btw i installed an o2 sensor eliminator
Thanks for the comments
hey sir, make a video about washing the bike properly because im afraid if it could damage the electrical devices
I will one day
Hi, did you try some additional box like Rapid bike easy or similar ?
No I did not
How did you master so many different topics sir?
MrZuhahaha thank you, age and eager to learn and explore. Never to old to learn

👍
Hi.... I have seen your video but my English is not very strong....
Can I have a traduction please???
I have install psb 13, I have more puissance but my vmax is the same.
What s the solution for take 10km/h for vmax
Thank you...
Thanks for the comments , not sure what you are asking my friend... you can write it in French
@@D3Sshooter
what do you think about the additional fuel box to order by dynajet for brixton?
Is it valid for the motorcycle???
What is going to contaminate a bike? This theory should be applied on industries not on bikes
Let the poor machine breath.🥺🥺
Edit:Btw Master very nice information.
Great point!
Valve?
Not sure what you want to say , can you explain ?
Very interesting video ! Can you tell us how you will dump the current ECU and with what software you will tune it ? I made some research and it seems that our Brixton uses Delphi MT05 EMS. Data sheets can be found here : www.huntermotorcycles.com.au/dealer/Dealer%20info-%20website/Service%20and%20Predelivery%20info/Delphi%20Scan%20Tool%20Manual.pdf
Guillaume Pinson txs and indeed it uses the mto5 -2 ecu from delphi. That should support the K line. And also the CAN bus on the diagnostics connector. I am going to use my own developed pid scanner based on OBD2. Normally the standard pids need to be supported. The problem will to get the fuelmap read out, interpret it and then build a new one with gradual changes. I will have the bike on a dynamo bench while changing. All by all a hard job. I just got a spare ECU. Getting the fuelmap might not be that hard as we think as there are flashers and loaders already on other bikes and cars with a delphi ecu. It is going to be trial and error. But will keep you all posted how i progress
Hi sir, is this pushrod engine?
Wai Kian hi, no its not. Its an overhead cam. Txs
OK FLEMISH, BUT AT FIRST HOW DID YOU KNOW WHICH WIRE IS WHICH. I MEAN BECAUSE YOU HAD FOR WIRES ON YOUR O2 SENSOR THEN HOW DID YOU KNOW THAT THIS ONE AND THIS ARE FOR RESISTANCE AND SO ON.
I AM CERTAIN YOU HAD A WIRING DIAGRAM. AND IF SO THENWHERE DO YOU GET THOSE DIAGRAMS.

Those are all parameters that you can measure and find by looking up the datasheet of the devices
@@D3Sshooter OK FLEMISH IF THAT IS THE CASE, THEN PLEASE MAKE US A VIDEO ON HOW TO CHECK A DEVICE ON A DATA SHEET. I AM CERTAIN IT WILL BE VERY USEFUL TO US
