This video follows on from my last one and goes through the process of building a new fuel map from scratch for my 180cc YZF-R125, the way I do it, using the Dynojet Power Commander V (PCV) and Autotune (with a wideband 02 sensor).
We go through all the various components/electronic gizmos and how they interact to get to the end result of a tuned bike.
I hope this makes sense cos I had to make a bunch of diagrams and stuff for it which took forever lol xD
This video is focussed on tuning using a PCV and Autotune which is a setup that seems to be working well for me, and for this sort of moderate tuning.
I know many of you have PCFC/PC3USB etc which is a little different and can’t use autotune, and the next video will be about what your options are in that case. Thanks for your patience and I hope it’s helpful 🙂
Would you be able to find out. How to repin the plug on a gen 1 yzfr125 to make a gen 2 throttle position sensor (tps) to work. To aloud the use of a bigger throttle body
heya – this was (inconclusively) discussed here: https://www.r125forum.com/threads/wr125-r-now-made-into-a-254cc-need-some-technical-help-please.20324/
It’s not something i’ve delved into yet unfrotunately. You’ll know when I have 😉
Heya
I read through that forum and couldnt make any sense of it tbh
I think the upshot was – atm nobody seems to know how to do it (that I know of) so you probably want to get a throttle body which is correct for your existing loom. It’s something I’ll be getting into at some point and will ofc publish what happens but I’m not that close to doing that yet. Is this the one you have?

Hello
No I’ve decided against massing around with the TPS and now I’m going to install a carburetor instead. I will let you know how I get on with it
oh fair enough. A carb though? that’s an interesting decision. What’s the logic behind that? Seems like a step backwards if you’re looking for power or am I missing something?
