Help to program Daytona sensors
 

Hi again everyone. I’m to the point now , I’m ready to program my Daytona ingitions. My timing is set at 28” I’m hoping to get more top end with a program that will let it advance higher at 4000 rpms and above. Any advice would be greatly appreciated! I have a computer tech guy who is also a motor head to help me install any thing you can advise. I have the MAP sensors, and all required hard ware. Just need a program. 468s iron heads, 250 B&Ms , boost reference carbs, 1000 cfm single carb. Cam ? DK no knock sensors yet. But no sign of detonation on plugs up to now. Thanks again SC

Have you downloaded the software and played with it? The software (especially a 2D map) is exceptionally easy to use, then plug if into the tach (brown wire) coming off the Ignition box and upload the timing curve you built and the other parameters you programmed (retard, idle stabilization, etc,.....)

I just installed mine this weekend and uploaded a tune to try as soon as we get a warmer day.

If your timing is locked to 28 you will never be able to advance timing beyond that. The box can only retard timing not cause a spark event to happen before it can physically happen.

Tech Tip : the most frustrating thing is figuring out which COM port your computers USB port is. PS, lots of them are COM5.

Since 2018 you`ve bought Daytona, returned Daytona, bought again Daytons and still trying to figure it out?
maybe blower motors are just not for you..

P.S. Your boat is a Scoripion , or Scorpion?

I know I seem crazy with this, my budget is a major constraint. I almost did sell the blowers, then decided to try to get them going. I’ve had good luck so far, thanks to all the help, and advice from you guys. I still think about selling them, but I have three years of all my spare time in this , and she does scream like a banchee! Also, I’m not the most literate bulb in box, so if I misspell Scopeon, please bare with me, lol. Sc

Hi, SC again, l have been thinking about what you said , Mabey I’m not right for blower motors, I am doing pretty good, considering I have only 19000 in this whole project. I bet some of you have that much in one engine. I’m not at all discouraged, it’s going to be a great summer! I really do need all the help, and advice you have to offer, that’s how I got this far. This will probably be the last year for the scorpion, too much crawling around for my getting old bones. Please mild, if you could send me that program you spoke of a couple of years ago I would love to see what this old boat could do. Thanks in advance, Stu

So - can you clearly articulate what it is you need help with. I'm confused as hell. Somewhere you had locked timing at 32. Now it's at 28.

Per my earlier post have you installed the Daytona ignitions? Have you downloaded the software? Have you followed the Daytona installation instructions?

No down loading yet. I have to wait for my bud, who is a computer guy/ motor head. My timing is set at 28” max , using the S.C. 800 pre installed program.

Why not just advance the timing 4* and be done??

On the contrary . (and it's 'Banshee' :p)

You know the difference between 'Advice' and 'Advise' :D
