Perhaps. You're not reading the usb voltages, are you? Those operate on a completely different spec, 0 to 5 volts, at a much higher frequency than rs-232. But it doesn't matter, if you've got data being sent both directions (meaning you're able to read back the internal data from the ignition module), then you did it correctly, and I wouldn't modify your circuit again.


If you have a working cable, it sounds like the official high prices cable won't fix your problems. It'll be the same version of software you've already downloaded, with a cable that, while implemented more robustly with fewer hacks, will perform exactly the same as the one you've built.

Try this instead. You're running Vista, correct? (This suggestion will work fine with windows 7 as well). Right click on the curvemaker application, either in your startment or in the installation directory and select properties. On the pop up menu, you should see a Compatibility tab. Click the check box for "Run in compatibility mode for:", and select Windows XP from the drop down box. It doesn't matter which service pack.

If that works, GREAT! If not, keep going through the list and try the other service packs, followed by the other versions. One of them is bound to work the way you expect it to. Good luck.

 

'88 FLHTC with an EVO 96ci S&S. Was running a Crane HI-4 which went out on a ride to Eureka Ca. I had to limp it over the mountains on one cylinder. Just got the bike back with a new Crane Fireball HI-4. Hope it holds out for many mile to come.

 

After building an adapter for a friend, sans converter circuit, I've discovered the fault in mine ... the cheapo $0.30 usb-serial converter. With a decent converter, it works perfect.

Thanks for all your help and insight!

 

i wanted to say thank you it worked very good for me.i had to change the dead crank revs to zero on my 73 xlch,thanks it was a breeze!!!

 

I can't say anything about the crane but I have had the Ultima programmable and the programming hook ups for quite some time on my slightly modified 89 EVO and it has been flawless. I would like to learn the programming part of
the package but there doesnt seem to be much on tech tips or how tos available, well other than how to wire the plug to the bike and opening software in computer.

 

You're correct, there isn't much information on the subject, but I think that's by design. No two customized bikes are exactly alike.

The average customer isn't going to be interested in putting together a custom curve. Without a dyno, there's not much chance of getting it right.

Somebody might find it useful to shift the whole curve a little bit, rather than physically turning the device to set timing, but this is more than likely a mistake, since you can't shift the first inflection point.

I don't know of any reason somebody would want to change the angle of the rear cylinder. I thought this may help my issue since I had a warped right casing, so if I set the front cylinder, my rear was off slightly. But while adjusting it in the programmer worked only for low RPMs and made things worse at high RPMs, so I ended up removing the case and fixing the warp issue instead.

Reducing the dead-cranking revs is very useful for kick starters.
And the information the reader stores on time at wide open throttle and max RPM is useful enough.

I think that's about it, right? Or at least that's all the nuggets of "wisdom" I have on the programming question.

 

For the Ultima/Dyna I would like to see:
- Other peoples advance curves! I have smoothed out one of the standard ones for my setup
- Has anyone used the two curves switching via the vacuum switch
- Has anyone tried the boost retard switch function and did it work? AND how the heck do yah tell anyway. I'm bloody interested in this function.
- I tried the rear cylinder offset but only for one trip...i can see how it would make a cylinder run cooler but did not notice any change - perhasp it was too subtle for me.

cheers

 

Why are folks making 'special' adapters for the Dyna Igniton? I just wired mine straight into the Comm 1 port on my old Thinkpad and away I went.

Am I missing something here?

 

I had the Crane HI-4 ignition in my old 80 evo loved it now I have replaced the engine with an Ultima and it came with the ignition in it I have 1800.KM on it no problems so far.
