RX3 ECU Remap help. - Page 2

Lukas · 08-02-2021, 05:24 PM

Dear charles, currently my bike is 249cc and the map is for 249cc, only when I buy a 299cc cylinder, it is possible that such a map will be created, I can make a video from A to Z, how to download the bin. ECU and how to upload TO your own ECU file, which you then send to oldschool tuning, you can write that you want one like mine and they will send it to you. When I change the cylinder, maybe I will be able to make a map for 299cc, in fact this is my goal, but there are still some problems, but it is possible that I will be able to solve them Now the bike runs really well, I can go to 5th gear, at 4000 RPM it accelerates nicely, before to 6200 RPM nothing was terribly mulled I also have the second map more powerful, but the bike does not run as it should, because you can not add parameters endlessly, but it may be ok on a larger cylinder.

Luke, would you mind linking where you got your Chinese open port? I have a genuine Taxtrix from tuning my Car, but other riders will not want or need to pay genuine pricing for these bike. Thanks.

The link opened for me, in Vivaldi, which even translated the Polish into English automatically. Here's another link to the exact same page, but in English:

Edit: Just checked it in Firefox and Opera; both opened it just fine. Opera even wanted to install the AliExpress shopping extension, which I declined.

They appear to be from the same seller: if you scroll down a bit they both appear to be coming from the "2088 Official Store". I would get whichever is cheapest at the time that you place your order. Right now, that's the first one; it's listed at US $208.78 with free delivery.

Here's a link to the HUD ECU Hacker web page:

https://netcult.ch/elmue/HUD%20ECU%20Hacker/

The button to download the program is almost at the bottom of the page

; there is a ton of connector pin out and recommended connection type information, in addition to some information on the Delphi MT-05 ECU itself. Quite helpful for anyone looking to alter the EFI mapping on their Chinese motorcycle, to say the least.

I know the seller write is of the same quality, but the cheaper one has no comments from the buyers and the more expensive is checked

Odd. Link does not work for me with chrome or microsoft edge on my work computer. But it works on my phone. Hmm. Unusual, because I can go directly to aliexpress on my work computer.

Lukas · 08-03-2021, 07:36 PM

I buy expensive one.

Good luck on the big block upgrade, keep us posted on your progress.

Also, be sure to check the piston skirt to crankshaft clearance on your kit before you seal everything up and start the engine for the first time. Choppercharles received a bad kit on his build and ended up going back to stock; hopefully yours ends up better than his did. Then you can tune the EFI to take advantage of the increased displacement, put it on a dyno, and let us all know just how powerful the RX3 can really be!

It wasn't the skirt contacting on my big bore kit, it was actually the wrist pin bosses were not machined down. Skirt cleared the crank, but not the wrist pin bosses. You can see the contact marks in the pic below:
