If you were to look at the data logs you`d see it it goes back and forth from your base timing to the max.. very quickly.


It adds all the timing all at once and then back down again.
I had 15* and then had it advance to 35* if I recall right .

Unless you have a really mild cam, you are not going to notice 5*. I'm kicking in 12 and I barely notice that. I would lock out the mechanical advance and use the digital so they don't fight each other. I haven't figured out how to increase the number of rpm set points so I can play with idle timing more accurately. If anyone has that figured out I would appreciate it.

Thanks for the info everyone. Ill be trying it out this weekend if the weather is decent.

If youre worried about hurting the engine, dont. The extra timing at idle wont hurt anything.

The idea is to keep base timing low , say around 16-18*,in nuetral, no load on engine. Then as its put into gear , the additional timing kicks in below whatever rpm you set it to, say 650rpm. I would add 20* worth of addtl timing for stabilization. The box doesnt add 5,10,15, 18, if you have it set for 20*. It simply adds 20, removes 20, adds 20, removes 20. It happens quickly, and you wont notice it on your tachs or your butt.

Last I heard, Bob Madera was the marine tech hotline for daytona sensors..Not even joking. Maybe he could be of help

Thanks. I'm not really stuck with a problem so I don't want to take up anyone's time with a phone call. I was just looking for general info on using the feature, how it worked and maybe get some tips on setting it up which I seem to have gotten. My concern was that if I gave it more than it needed the rpm would hunt up and down as it kicked in and out but that doesnt seem to be an issue from what everyone has said. Still haven't tried it yet, maybe I'll get around to it this weekend. It's actually idling good at the expense of being a bit too rich, so I figured I'd try letting the box do its thing and see how it compares.

I hope you have better luck than me. I think my CD-1 is bad, I'm getting pops and backfires when it's in idles control. As soon as I get above that range it smooths right out. My old MSD 6M with timing fixed at 34* ran better.

You checked it with a timing light to make sure the timing is where its programmed to be right? What does the datalog show ?

Checked and double checked the timing. You can see the timing bounce from 24* to 36* at idle speeds below my 800rpm requested value. I haven't had a chance to download the latest datalog yet. I have looked at previous logs and everything looks fine. The popping and bacfires are something new that started today. I programmed a new download that basically locks the timing at 34* and will try that without idle control.
