My run in with it happens with speed sensors like crank or camshaft
triggers somebody has run a high draw wire by the speed sensor wire and
you get erroneous numbers or no discernible signal as it has squished
the square wave the ecu is expecting.

Can you even get the engine to run when that happens??


During the start procedure the crank trigger generates 35mv in a square
wave pattern every time the crank hits tdc. So when you get interference
the square wave looks like straight dc. Depending on the condition of
ecu it fires all the time or not at all.
The other place is the radio heard a Losing power every time I use
radio. Never got to look at that one the team just moved all the radio
wires. Had a camera system that would freeze as the driver stood on it
to exit grid 3 times in a row it froze same point just as he brought up
the revs and the grid worker was pointing him on the track.

The other commonly interfered with is wheel speed sensors becomes
critical in ABS and other traction control stuff, we get get bad wheel
speed numbers but no effect outside of loss of data analysis we do use
gps but that will not show wheel lock up. & GPS at 5hz is very
inaccurate at 160 miles an hour and worse at the banks of daytona in a
prototype.

But the bulk of the issues comes from the wires or the routing of the
wires. Wires are a lifespan item and you need to do maintenance or
replacement depending on lifestyle of harness. Contacts and connectors
wear and subjected to environment conditions determines the rate. The
ground shielding surrounding the harness can be pulled apart and damaged
in use allowing interference in or out. Then the variable that you have
no control over is the other car in vintage or historic racing there are
all types of ignition systems for example most are one of a kind and
stretch across a hundred years of technology.
I have 3 or 4 emf-- radio and rf testers I have been looking at a
spectrum analyzer just do not do enough work with it yet. But often I
will carry my meters and walk grid and look for interesting signals as
the car is warming up just before they hit the track.

The other world is beacons and those things that trigger the lap time
signal start/finish point for the data system on the car, many have gone
to GPS but often others use a beacon. This can be complicated by
multiple teams putting out beacons or putting beacons to close to each
other that they cancel themselves out or other types of telemetry
devices in the pits.
There is nothing that ****es a driver off more than running a 30 lap
race and downloading one big lap and not seeing his lap times.

"GPS at 5Hz" - at best, GPS gives position data once per second. You
can extract sub-second timing data from knowledge of the waveform and
its data packets.

How about posting the wave form and data packets of the FORM EMAIL?
Damn, that's funny. Always.

Say what, dumb****? New Year's Day is for football. Only blithering idiots ski on holidays, you blithering idiot. Kids are out. Long lines. Gumbies. You.

I knew you were stupid but this post is as stupid as skiing today.

New Years is one of the best days to ski. I always get out there early while people like you are still sleeping off their hangover.

23rd sober New Years in a row, dumb****. You're the ****ing amateur. Idiots ski holidays, and we all know how stupid you are.

Skiing in the morning on Jan 1st is one of the least crowded times I ever get to ski. I'm off the slopes by noon which is when most people start dragging themselves out of bed. And people like you are so hung over that they never make it out.

Holy ****, how retarded can you be? Every day you up the ante. Unlike you, I have never had any substance abuse problems. You're just projecting your drunkenness on other people again. Everybody knows how AA works. It's been on almost every sitcom or drama on TV for the last 50 years now and it doesn't work. To bad you didn't find out about it until it was to late and your brain cells were already fried.

I know it's hard for you to comprehend that there are people like me out there who can drink socially and not let it take over their life. I may have been drunk in college a couple of times but I'm never over the legal limit.

Call your sponsor right away. He may be able to help you but chances are when you fell off the wagon this time, you hit the ground hard and got run over.

You're just displaying your ignorance again. The morning of new years is one of the least crowded times to ski. But you wouldn't know that because by the time I'm getting off the slopes, you're mixing up your first bloody mary for a bit of hair of the dog.

Holy ****, you lie without any evidence at all and accuse me of drinking, and you call ME retarded? While hiding in anonymity?
BWHAHAHAHAHAHAHAHAHAHAHAHAHAHAHAHAHAHA

Every day you up the ante. Unlike you, I have never had any substance abuse problems.

Fair is fair, eh, pussy? You got a problem with me thinking a judge put you in AA, and you have the gall to accuse me of drinking?
BWHAHAHAHAHAHAHAHAHAHAHAHAHAHAHAHAHAHAHAHAHAHAHAHA

What drunkenness, you stupid dumb****?

Everybody knows how AA works.

No, they don't. Bull****. Especially you freaks.

Works great for me for almost 24 years, but since you are a clueless drunken idiot, of course you would say it didn't work for you.

To bad you didn't find out about it until it was to late and your brain cells were already fried.

Funny how those cells see you for the dickless, lying piece of **** coward you are.

Your incoherent ramblings are plenty of evidence that you are off the wagon again. Call your sponsor.

You started it with the 'take your meds' crap but obviously you can't handle it back. That's the alcohol talking. Call your sponsor.

You're just projecting your drunkenness on other people again.

What drunkenness, you stupid dumb****?

The drunkenness that causes you to continue with these incoherent ramblings.. Call your sponsor.

Everybody knows how AA works.

No, they don't. Bull****. Especially you freaks.

Whatever, 12 steps, sponsors, dismal failure rate. Yes, everyone knows how it doesn't work. Only a drunken fool thinks people don't know how it works. BTW, when are you going to apologize to everyone here? Call your sponsor.

Never had to try it. No substance abuse problems here. It's the alcohol that is causing you to project your problems onto other people. Call your sponsor.

To bad you didn't find out about it until it was to late and your brain cells were already fried.
Funny how those cells see you for the dickless, lying piece of **** coward you are.

It's the alcohol that causes you to see things that way. Plus the fried brain cells. Call your sponsor.

I know it's hard for you to comprehend that there are people like me out there who can drink socially and not let it take over their life. I may have been drunk in college a couple of times but I'm never over the legal limit.

I know it is hard for you to comprehend that there are ethical, decent people out there with manhood and balls, who don't let the urge to be a lying piece of **** coward on usenet take over their lives.

I haven't posted anything in months and now I'm just bored at work and ****ing with you. You on the other hand have been posting almost every day, multiple times per day. Who has let usenet take over their lives? It's the alcohol that has you thinking that way. Call your sponsor.

Call your sponsor right away. He may be able to help you but chances are when you fell off the wagon this time, you hit the ground hard and got run over.
What do you mean "this time", clown? Ain't fallen off since I got on, you dickless wimp.

That's the alcohol talking. Call your sponsor. He may be able to help you get back on the wagon but I doubt it.

And there you go again, lying your ass off. How disgusting. How normal for an rsa freak. Make up a lie with no evidence, continue to lie when exposed as a liar. Typical of a dickless coward hiding in anonymity.

Please call your sponsor, Scott.
