has anyone had issues with the skyhook faults? I get one every so often and then it goes away Image Unavailable, Please Login
Terry identified one issue. Also sometimes when putting the car on the ground from a hoist that happens. I am not big on ignoring warning lights but if its sporadic the suspension warning lights have been a little glitchy so I dont spend much time worrying about them. Its not like an alternator or oil pressure light that may snowball into a real issue.
I once got the suspension warning light in my 550 just by pulling into the gas station to fill up. The two tires on the right side were on the concrete patch next to the pump. The two left side tires were on the asphalt which was 3/4" below the level of the concrete. When I started the car, there was the suspension light! When I restarted the car after a 25 mile drive, the suspension light didn't come on. Funny how a 3/4" incline triggered the suspension light but the 31º of banking at Daytona didn't...

Terry, on that 31º of banking, there are several vectors of force acting on my car: Forward acceleration Drag Centripetal force Centrifugal force Here's a close-up of my car on the banking... Image Unavailable, Please Login I'm keeping my car a fixed distance from the double yellow line yet the rear of the car is swung out a bit. You'll see this in videos of NASCAR races at Daytona too... Image Unavailable, Please Login I think this video explains what's going on pretty well... The rule at Daytona is to keep the right rear tire inflated ~4lb higher than the other three tires. The right rear tire is the one that is at risk of blowing out if this is not done. I've seen this happen several times when I'm at Daytona. Compression is definitely not the same on that high banking, yet it doesn't trigger a suspension light. I'll never understand why. I guess it's another one of those "Ferrari Wonders."
Barry- Yup, I understand all of that. A lot like flying an airplane and centering the ball with ailerons and rudder, even though your 550 was crabbing to stay level on the pavement. Still, with 4000 lbs of car and 1.15 Gs from the banking (4600 lbs), the suspension is compressed and probably below the sensor limit where it provides a suspension lamp for being unequal side to side.
Yes, that's the logical explanation of how my sensors behaved on the Daytona high banking, Terry. The illogical behavior of my sensors at the gas pump is still a mystery to me. It only happened twice several years ago. I still get gas at the same gas station with its slightly elevated concrete patch adjacent the pumps without lighting up the suspension light. As I said, it's just another one of those "Ferrari Wonders." But back to that 31º of banking at Daytona for a moment. I could feel my 550 and F355 Challenge lose some of their forward acceleration vector of force in the banking and regain it as the track leveled off. Even NASCAR cars experience that despite all their horsepower. Listen to the engine's change in pitch in Dale Earnhardt Jr's car when he's on the high banking... And, yes, you feel yourself pushed down in your seat and only able to see out the right side of the windshield when your on the high banking. But as dramatic as that is from inside the car, it's even more dramatic for the spectators...
I’ve only raced once on an oval (Iowa Raceway) and it’s only 12-14 degrees and at the time it seemed insane. I cannot imagine 31-degrees.
Eric, the first time I was at Daytona back in 2009 I had to go out with an instructor. Using the Rolex 24 Hours course, you pit out onto the flat infield road course. Getting out onto the tri oval is abrupt and you get right into the banking. At the end of the session, my instructor said "it took you four laps until you felt comfortable." I asked him how he knew that. He replied "You forgot to put on your gloves." He noticed that my knuckles turned white gripping onto the steering wheel those first four laps.
I’ve raced Daytona twice. It is quite easy at the amateur level since most of our race cars are horsepower limited. That means we are flat out on the banking waiting to get to the infield which is the only place we can make up time. Daytonas severe banking makes it easy to be flat out. Whats scary is mild banking like at Homestead or Autoclub speedway where you have to be brave to keep your foot in it with a higher HP car.
For the record my oval experience was in my NB Miata (before) I went turbo….so a whopping 140 hp! ;-)
Right, FBB. I'm flat out on the banking with my F355 Challenge. It's amazing how it picks up speed when the banking decreases. And then suddenly it's time to slow down to enter the infield road course and the bus stop on the back straight. Still, one has to be mindful of the double yellow line. Slipping below it onto the apron could be disastrous. As the track announcer says, at Daytona "What goes down must come up..."
Yeah you could be flat out on any banking, answer your email, take a nap before you get off the banking
so I think I found the issue with my sky hook system, the front sensor lead was routed by a frame piece and subsequently wore through as you can see in the picture. I did a splice and re routed the leads away from the frame. I now have to clear the fault codes if you have a 575 or a 550 I am willing to bet that your front sensor leads are routed the exact same way and will eventually cause a similar failure Clyde
