Daytona sensor CD1
 

So I've been talking with a guy who is telling me to change from msd to daytona sensors he will write the tune for me to help with my idle issues when shifting into gear. What's the consensus on here about the unit. The boat runs great its just running pig rich so i don't stall it it at the docks. The boat was originally tuned and set up by john teague i quickly learned i canty operate about like he can. He can shift with the surge of the blowers and has no problem at all. Me not so good. So i took it to anthony at HP Mafia he got it to where i could at least drive it. But I want it better. So any suggestions or info would be great. Thanks for your time

Boat 38 fever Motors are blown 540s dual holley 750 double pumpers making 875hp at 7lbs of boost on 91 octane with chillers current ignition msd locked out at 32 idles around 1k and drops to 700 or so when i shift. I have a feeling they are set pretty good for these cooler temps but when it get warm tends to real rich smokes and slicks the water.

I have the Daytona system on my boat and it's amazing. I use the idle control with a steep timing advance below 1000 rpm. I have the physical timing set to 36 degrees and then use the Daytona box to set my actual timing. This allows me to advance the timing to 36 degrees when the engine drops to 500rpm. my idle timing is at 24 degrees which allows me to open up the throttle blades a touch at idle. Between the reverse timing curve below idle and the idle control it runs like EFI. I boat in very cold water and it starts much faster and idles great without a choke even when it's cold (40 degrees). You will be able to bring the idle down in neutral and you won't see as big a drop in gear. I can idle at 700 rpm in gear all day long when cruising down the river. I also have a timing retard switch connected so I can retard timing 4 degrees if I have to get marina gas.

This sounds like a dream come true I would love for my boat to run like that. What motors are you running? So I assume you were experiencing the same issues I am having? What distributor running? Thanks for your time

correcting the timing will also help fix the blower serge, ya it sounds cool but its a PITA

John had the boat set up with blower surge and would use the bottom of the surge to shift so the motors wouldn't stall I just am not that good of driver. **** watching other boats the docks trying not to stall the motors everybody staring at me. I need 10 Xanax by the time I get into the slip. Most of the blower surge was taken out by Anthony at HP Mafia at the Ozarks He adjusted it on the water with idle mix screws it ran pretty good the whole time I was at the lake that week. But is very smokey and slicks the water from unburnt fuel come out the exhaust. And I just want it more dock friendly I have even considered turning props out. But have been told not to do it so I haven't.

DS upgrade stands out as the single best purchase I've ever made on a boat.

My engines idle, don't stall, etc.....

ThisIsLiving helped me get up and running and I'm so much happier.

I have 800 HP 565's, normally aspirated, talldeck single carb Dominators which don't make dick for vacuum. This fixed it. I run locked timing in my distributor and just let the box/tune that I loaded handle everything.

This is the feedback I was hoping to get. Thanks for posting. I'm definitely leaning toward getting them. I'm waiting to speak with the guy that's gonna get me set up. Hopefully will be able to talk with him this weekend.

Thats pretty damm funny 😆. I barely had time to do a shake down last fall on my boat so I didn’t have time to correctly tune my Daytona sensors and just used some ready to go distributors with 24 deg adv. Engines ran great and super strong but cams are pretty wicked SR’s and can’t idle below 1,300 + without stalling when shifting. Local launch has dock about half the length of my boat and throw in a windy day can quickly make a **** show. Entertaining for some I’m sure but at least they all run to help.

So in a marina trying to dock with stelling headers dry to the tip would likely ruin sale boaters day/night. 🙄

So yeah I get the zannies and v’s 😂

Dude - I know the feeling!!!!! Lunch stop we go to most often is tight parking and it's RIGHT IN FRONT of a 2 story outdoors deck. There are no other go-fasts in this area and I have dry pipes. It's the worst case scenario. We NEVER leave without at least a dozen people filming - there is no room for error - I'd just look like the biggest ASSClown in the country dealing with uncooperative motors trying to back into those slips.

The Daytona Sensors stuff is very easy to use. Takes a few hours to wire it up, but well worth it.....

whats the cost to switch from msd?

From whatvimnseeing each box is about 825.00 but I figure my MSD stuff is basically BN so should be ablentonsellnit and recover 300-400 bucks for each.

The guy I'm talking to is gonna send me the links to what I need to buy later today. I'm doing it

Boxs got delivered today. The change is happening. Can't wait!

Sweet - you have o2 sensors? Are your dist Hall affect or mag pick up. Mine were ready to run plus coil and had to wire a different way and I was still getting some funky readings so getting a couple DS distributors and starting with the recommended NA program and go from there.

You`re in good hands with Joe G. (Mild Thunder on here)
Does sound like you`re way too rich and need to get that ironed out too .

wow wasn’t aware he was on here. That’s awesome

https://cimg8.ibsrv.net/gimg/www.off...e9a038868.jpeg


I do have o2 sensors I need to get spacers and new sensors mine got wet and aren’t working now. mag pick up they should be finished this weekend. Just been to busy to get it done.

Man it's been a tough summer. I'm trying to make the nationals in Hilton head for golf. So the boat has been on the back burner. But the new Daytona sensors Cd1 boxs are installed. Joe is coming down soon to tune them. The boat is going out this weekend. Here it is july 14th and the boat has yet to be out. Well next weekend she is gonna rip it up! I will update later

Joe , as in, Mild Thunder ?

I got these going on my 1000sc motors now. Pretty pumped i hear the idle and docking qualities are awesome!

Yes I believe so. I'm sorry I only know of Joe from local friends and not from OSO.

Love my Daytona Sensors ignition. First time out this year, it started right up. Let it idle for a minute, put it in gear and you would have thought I had EFI. I don't have a choke and I don't need one, it runs as good cold as it does warmed up. Once I've started it for the day and have fuel in the carb, I just have to hit the key and go, no pumping the throttle. I know the embarrassment of trying to dock when the engine keeps dying. I was trying to dock in a very narrow ramp on a river with a decent current and a bad ignition module. The people on the other side of the river really gave me the business. My wife was pretty ticked as well. Now I can idle in like dream. Shop around for it, I only paid $450 for ignition and coil.

$450 for ign and coil...used or new??

I've been eyeballing these for a while, but the price seems like I should just go the extra mile and convert to Holley EFI.

The Canada exchange and for 2 engines makes the Daytona a big chunk of change upgrade...but a worth while one at that.
​​​
But I do like the reliability of carbs.

The best part of the Daytona is the part throttle and idle advance.

Is there an input for a MAP sensor input for the timing output?

So I asked Joe tonight if he was mild thunder. Yes it is him. We are meeting Friday afternoon to finally get this fountain manageable for me. What a small world and great community OSO has!

I'm gonna be honest I'm not a engine guy. But I did ask John about going holly sniper. And he told me not to do it. To many gremlins. Now with that said he didn't express himself anymore and this was his opinion. Sorry I can't give more of a answer. When is asked him about Daytona sensors he said he has heard great things and the only reason he went msd was cause of support and being familiar with there stuff. Again his opinion.

When I talked with a few people of of OSO they swore by Daytona sensor and then the response I got from the community in here to me it was a no brainer. I honestly hope some more people will chime in for you. If they need to talk about holly sniper please feel free. I think it would be a benefit to the community and just maybe someone else on the fence would find this thread and be able to make a informed decision.

I wish you the best in what ever route you decide to take

I stuck with Carbs and the Daytona Box. Largely my issue was that I still have mechanical fuel pumps so I would have had to convert to electric FP’s, and I don’t have Oxygen Sensors so I would have had to pull the tails and send them off to CMI to have Bungs drilled. None of that was a ton of work, and I might go back and convert, but for the time being spending 600/motor on the Daytona’s was a no brainer and would pair nicely with the Sniper’s if I ever got there. It’s funny that there aren’t a lot of converts on this website - it certainly gives me pause.

I don't think the Daytona Sensors is very well known, or at least eclipsed by the MSD name.

Add the fact that most people like to use tried and true parts.
​​​​
When you add up the changes and parts to go efi...it adds up quick.

I just happen to have O2 bungs...so that helps a lot.

I have 420 Blowers, with 2x 750s, so MPI is harder for sure, and I would not want to run 2x Snipers per engine.

Likely the best scenario is a good Wideband O2, with a quality Daytona style map'able timing curve, and tune to a healthy cruise rpm. Not be as focused on perfect wot efficiency...not there for long anyway.

Running Arnesons at the dock with a reliable low rpm would be better all around.

Daytona Resale value should be good as well.

Daytona Sensors I believe are the guys that were behind the Crane HI-6 boxes. When Crane was changing ownership they went out on their own and built the CD-1. It is a tried and true product, just under a different name. I believe the Crane HI-6M boxes were the best marine ignition box ever produced.

I sold my Carb HI-6M setup and went full Holley multi-port EFI and it is amazing.

He has been an OSO member for a very long time and used to post a lot and gave great tech info. He got tired of some the typical OSO drama and has not posted much for the last couple years. I wish he'd come back and start posting more again.

^^^^ 100 % correct ^^^^

I have a Crane Hi-6 that came on my Formula 233. Will have compare them.

Hoping it's still functional. Would be great as a spare.

So I spent the whole day 7hrs with mild thunder he got my boat running good.

we did run into a little issue that took 3 hrs to figure out. I’m gonna ask him to come in and out it into his own words. I definitely think it would help the community out out if some one would run into this issue.

I just read we’re the some of the OSO community might have ran him off. I truly hope this isn’t the case because the community is sadly missing someone not only knows his **** he loves boating and high power.

if he chooses not to come in post I will share. The information.

I’ve been on OSO for a long time and people like griff and Icdpl hope I spelled that right have always chimed in and answered me. Im so great full to have a place I can come and ask questions and all of you boys help. The only issue I have is I wish I could also do the same thing one day and help and return the favor to the community. Thank all of you loyal OSO boys! I truly appreciate it.

This is what happens when the community comes together.

Hey Griff and fellow oso pals! I know I havent been on here much if at all the past few years. Wasnt really anything to do with the oso drama, mainly just because I sold my boat and have got into other hobbies. I still tinker with some boat stuff here and there, but mostly been doing the classic car thing. Recently got done with my 78 T/A I installed an LS3 in with Holley EFI , Tremec trans and so on.

As for Ubet28's Fountain , it had MSD setups with the timing locked. He had a local guy install the Daytona ignitions. Yesterday, I met him at his lake, uploaded the timing maps I had made. Now idles at 18* and adds 14* if the idle dips below 750rpm. Made a few tweaks to the carbs and off we went. Got up on plane, cruised at 3000RPM, gave it a little throttle and bam, starboard engine quits like you turned the key off. Opened hatch, everything looked fine, started it up and got going again. This happened two more times. Just the ignition completely cutting out over 3000-3500. I pulled a datalog, started checking connections, really scratching my head. Then when in the bilge I had noticed the coil wire was draped across the top of the ignition box. I thought "let me move this wire away from the box , maybe its getting some RFI or something" , and finally the problem was solved.

Unfortunately by that time it was getting late and I had a 2.5 hour drive home. The carbs could probably use a little further tweaking, but overall, the boat is very useable now. Starts up well, Idles around 950, and only drops to 750 when shifted into gear. Ubet said it used to drop to 500rpm and sputter when shifted into gear with the old setup. Hopefully now he will get to enjoy and use his boat .

Mild Thunder, I have seen your car, it is very nice. Are you interested in showing it at the Chicago World of Wheels? If so let me know. Sorry for the hi jack.

Hey, is that you Bandit?

So the coil wire across the control box would cause the engine to quit over 3k RPM? That's interesting.

Thanks for the info.

I would be interested. I wanted to this past spring but it wasnt quite done. Where did you see it?

Were you just at the Palos Car show on Thursday? If so, that was where I spotted it,. If not there is one that is a twin. Either way contact me and I will VIP the car.

Yes I was there. I was parked on the side street by Lumes pancake house. Got there a little late. I'll shoot you a PM. Thanks

Hey Buddy drove the boat all day yesterday cleaned the transom off Friday night at the beach we stayed at. Boated all day Saturday idled in the marina Saturday night waiting to load for a good 15mins Not a lick of soot on the transom! The boat is running the best it ever has! For me it’s perfect I’m sure you would be able to dial it in a tad more. But that’s something I’m gonna learn to do. For now I’m gonna just use the boat. It’s been a whole year of owning her and this weekend is the first time I was able to just whip into the dock load the boat on the trailer like I’ve been running a blower motor boat for years!

Still need seat time with the boat of that size props turned in and blowers. But man with you and the boys on here that boat might of been for sale! Thank you so much Joe and OSO boys for steering me in the right direction.

if anyone is having the issues that have been spoken about in this thread. Do not think twice about changing to Daytona sensors cd1 boxes. They have completely fixed my problems and my boat is manageable and do able!

yes I boated all day Saturday and the boat didn’t miss a beat after Mild thunder moved the coil wire. I can express how much these boxes change my boat! Absolutely amazing my wife my son both told me man this boat is running great and you look so much more comfortable driving it.

before this weekend I was told I needed to wear this shirt! Lol

That's awesome! Congrats and thanks for sharing! I love my Daytona Sensors and my buddy Joe lol!

Great to gear success stories like this. Glad you got dialed in.
