2022 HI-TEC OILS BATHURST 6 HOUR

[chavez]

The sixth running of the Bathurst 6 Hour takes place this weekend.

With seventy entries and no virtual safety cars, no code 60, etc expect the real safety car to feature in the fight for a podium finish.

Nevertheless the entry list is filled with some of the best drivers in the country and and a huge variety of cars in terms of marques and performance.

Who will win?

Well Ambrose is driving,, so Ambrose.

Ambrose and Miedecke out, Mustang has electrical gremlin according to Speedcafe.

[ford71]

Meh...he'll still manage a podium.

I find it rediculous they couldnt sort an electrical gremlin with all the Techs they have available to them.

And being a Ford dealer himself.. service department should have been able to sort it..
Maybe the car is.. slooooooow…

You have never worked on a modern car and had to diagnose the electronics. My son does electronic diagnosis for a living and even the major Japanese brand he works for can't diagnose some problems at head office level. I am serious here, some think that computer diagnosis is simple and straight forward but some issues take days and weeks to diagnose. Modern wiring harnesses cost thousands for each harness and there are quite a few harnesses in each car before you even begin to look at components and the problems they cause.

Quite a few cars with electrical gremlins were parked in a lot at a Toyota dealer in Brissy recently. Not able to be moved to higher ground in time. Terrible luck for those owners.

And, back at first principles, you identify the 20 things it could be, in components, and change them out one at a time, try again, to eliminate them as the source of the failure.

If the Mustang is a standard production car, wouldn’t pulling one off the dealer lot and facilitating this method of error elimination produce the desired result?

As I said you have never worked on a modern motor car and your response shows that. You should get a job as a electronics expert in a dealership and show everyone what they are doing wrong as you obviously know more than the guys who do it for a living.

How many laps of the race track do you do before you are satisfied the each problem is solved.
Surely as an expert you would have an exact answer.

Not electrical (as in swap components) but electronic. It's not unusual for production car systems to become upset/confused in racing conditions, the same thing (effectively) happened with the BMW's when they started racing 15 years ago, plus others. Eg I can think of the A45.

That said I'm surprised they don't have the Mustang sorted out, but I suppose any racing in the US either doesn't start with a standard road car or rewires everything from scratch with standalone ECU etc.

Being a Ford you have to reprogram the replacement modules using Ford IDS software too.

For the most part you can't just swap modules in a CANBUS car, but rather you have to reprogram them to the vehicle.

A good auto-electrician who can backprobe and read CANBUS (digital) signals is invaluable!

Here's a BMW that refused to start because the door handle had a short circuit. Naturally it made sense to Hans who assumed the door handle would never become faulty, and hence it was perfectly reasonable for Hans to require a signal showing the door handle wasn't being opened as a condition for the car to start!

The video also gives a good example of the kind of diagnostics that can be carried out on a typical modern CANBUS vehicle with dozens of modules (there is nearly a module for every little feature the vehicle has, of course not all relevant for the drivetrain), and the digital signals that travel between the modules.

Sure, the good ol' test light it still invaluable too, but in the case of the BMW it went through multiple workshops before it reached someone who knew what they were doing.

Conversely, some car owners seem to place too much faith in the onboard diagnostics and think fault codes would give all the solutions, which is obviously not correct either.

Puts the Begg/Russell/Morris car to pole, with car owner Mr Begg starting..

The internet trumps actual workshop experience and someone people actually believe that electronic diagnosis in modern cars is simple when sometimes the manufacturer cannot diagnose problems without going to a lot of trouble. Simply put mister GTR you don't have a clue.

In your opinion. Which just happens to be not aligned with reality. Yet it remains your opinion. I never said it was simple, nor impossible. It needs thorough root cause review. But why let possibility get in the way of giving up.

In the meantime, a 2.24 with 5 1/2 hours up on the Hill/Sargent BMW is MEGA!
