Exclamation Re: Warrantee

Paul I am not referring to the vehicles ECU I am talking about a Event Data Recorder (EDR) a totally separate unit that is in many of the car manufactured today. This is the same technology that the FAA uses to determine the cause of an airplane crash. Here is just a list of the minimum
requirements called out in the National Highway Traffic Safety Administration 49 CFR Part 563
Data Element
Recording Interval / Time1
(Relative to time zero)
Data Sample Rate
Samples per Second
Delta-V, longitudinal
0 to 250 ms
100
Maximum delta-V, longitudinal
0-300 ms
n.a.
Time, maximum delta-V
0-300 ms
n.a.
Speed, vehicle indicated
-5.0 to 0 sec
2
Engine throttle, % full (or accelerator pedal, % full)
-5.0 to 0 sec
2
Service brake, on/off
-5.0 to 0 sec
2
Ignition cycle, crash
-1.0 sec
n.a.
Ignition cycle, download
At time of download
n.a.
Safety belt status, driver
-1.0 sec
n.a.
Frontal air bag warning lamp, on/off
-1.0 sec
n.a.
Frontal air bag deployment, time to deploy, in the case of a single stage air bag, or time to first stage deployment, in the case of a multi-stage air bag, driver
Event
n.a.
Frontal air bag deployment, time to deploy, in the case of a single stage air bag, or time to first stage deployment, in the case of a multi-stage air bag, right front passenger
Event
n.a.
Multi-event, number of events (1,2)
Event
n.a
Time from event 1 to 2
As needed
n.a.
Complete file recorded (yes, no)
Following other data
n.a.

Notice that the Speed and throttle position are recorded two times per second so a change in throttle response could easily be seen.

So far only Ford and General Motors have been installing EDRs in cars starting in 1997; our Crossfires do not have an EDR installed. Here is a list of all cars with EDRs: http://www.harristechnical.com/downloads/cdrlist.pdf
