ABS COMPUTER BULLS#!+ INFORMATION

Paul,

Honest mistake....you will never be a Politician. My first wife was and she always blamed someone else for "bad" info.

 

Thanks paul but it does work does it not?

 

I for one appreciate the information. If he's been riding around with it, then you know it's fine for testing, and that's what I want as I troubleshoot the system.

 

Might work better

 

Given that Ferrari, like every other car manufacturer, goes to the vendors for hundreds of bits that make up a car beyond the bodywork and castings, it was not unreasonable to assume that they could have sourced the ABS unit from the same place Lincoln did. And who knows, it may yet prove to be the same unit, or it may not be.

 

I've replaced my failed original unit with the Ford ATE computer and it had worked fine for years.

 

The picture ClydeM posted shows the units are not wired the same. There is a difference. Worth the cost savings?

 

I think his picture just showed the pins were labeled differently (as you'd expect, to match the wiring diagram),but the connections looked identical. They're probably physically identical but perhaps subtle programming differences? I had mine open once to repair a ground but can't remember if there was a removable chip inside. If there is...

Either way, if the car is happy and abs is working it doesn't much matter as these weren't racing abs units (obviously if used in a Lincoln).

 

Pete if they are identical, great.
If I am reading the schematics correctly on the Ferrari unit there are 6 unused ports 19~35 and 1 unused port 1~18.
On the other unit 19~35 unused ports 8. 1~18 unused ports 3.
I have no idea if this alters the performance of either ABS ECU.

 

Anyone know someone on the inside at ATE? They could tell us for sure.

 

I would suspect that the with Lincoln unit fitted to the 348, the ABS would probably cut in earlier due to car weight and brake balance differences.

The system will work, just not as efficiently as it should do.

I'd also have to say that in most incidents where ABS is useful: being able to steer round an oncoming incident whilst braking hard, the vast majority of drivers either completely forget that they can still steer and so just drive into the accident regardless, or simply have no where or no time to steer away from the incident so have the accident.

Basically, as the ABS system has no effect on everyday/normal use of the brakes in terms of power or balance, I'm not convinced it makes that much of a difference.

Put it this way, the 328 came both with and without ABS, and you don't hear that non-ABS cars are more prone to crashing than ABS equipped cars do you? (In fact, the non-ABS cars are often the more sought after cars).

However, I would also add that it is more ideal to have the correct version fitted where possible, if only to avoid an insurance accident investigation refusing a claim due to a non standard piece of safety equipment being fitted should the unfortunate happen.
