I understand what you're saying from a theoretical standpoint and have done a lot of reading on the topic, but if you look at the MSL file, I don't really see a problem. It happens too fast in terms of ms to matter I think, as the KTM idles around 2000 RPM. If the fat tooth was causing issues we ...

And that makes sense as to why it doesn't ever see itself as "cranking" but if you look at my MSL file, you'll see what looks like a good crank signal to me and it still doesn't see itself as "running." Do you know if Cranking and Running require any other inputs? Could the fact that it doesn't see ...

Here is a good example log and my current tune.

Thanks for any help!

Hey guys,

Backstory: (copied from my other post) I'm trying to do fuel only on a single, fat tooth setup (I know) using the stock CDI system for ignition. The tooth is only about 28 mm long, so it's not crazy long. This is on a KTM 525 engine, and there are not a lot of attractive options for a ...

Some additional data that may help:

Here is my MSQ file. I have only been testing to see if I can get a tach signal to work, so lots of other things are probably quite messed up.

In addition, here is the log file from earlier when it was reading double. Interestingly, after looking at the log ...

Hey guys,

I'm trying to do fuel only on a single, fat tooth setup (I know) using the stock CDI system for ignition. The tooth is only about 28 mm long, so it's not crazy long. This is on a KTM 525 engine, and there are not a lot of attractive options for a trigger wheel, and to be 100% honest, I ...

Hello!

So I finally got an 18-1 tooth trigger wheel installed for my project and a VR sensor off a Yamaha YFZ450. (Bench test setup, simply cases, a crank to spin by hand, the trigger wheel, and a VR sensor) I fought with it for a while Monday night, but was unable to get a signal to show up in ...

Mike,

Thanks for the reply! I'm not sure what the cranking RPM is, but with the idle being set at around 1800, I doubt it's anywhere near 50!

I was really shocked by the 50° as well for the YFZ, but that's what I saw on the Dynatek website for their CDI. I think they claimed the stock map was ...

Hey guys, (Edit: I started this as a separate thread, which was not the right thing to do, so it got moved to here, and some of the same information as above is contained below, but the question is still open)

This is my second post on this topic, but we’re planning to machine one of the 18 teeth ...

Hey guys,

I race ATVs in the Grand National Cross Country series. These are single-cylinder 4 stroke engines, and we do dead-engine starts, where the flag is thrown, you start your quad and take off for the first corner. To get there quickly, I’m running a second battery on the way to the starter ...
