ABS Actuator ECU Update Decrease Fuel Efficiency?

No Change in MPG, you will still get 25 miles per gallon...

Seriously, if this is only an ABS ECU software update, you shouldn't see any change in fuel efficiency. ABS only comes into play when you are braking on a slick road where the ABS system detects that your wheels are not turning (or should I say slowing) at the same rate. ABS is typically only activited < 1 % of the time you are braking,

Fixing the bug is more likely to increase mpg, not decrease. The abs was over sensitive going to hydrolyic early. That said I would not expect to notice the change either way.

 

Suppose the change activates the brakes with less pedal pressure. This would reduce regeneration, slightly reducing fuel economy, shorten brake life, and contribute to global warming (friction from the brakes).

 

My butt gyro is really old and not really reliable anymore.

When it felt the sensation of bad brake feel (reduced braking at transition for those that don't speak euphamism). It felt as if my tire should not be slipping. A later activation (the tire stopping instead of just slowing) would likely be the corrective firmware. Then increased friction braking to match the regenerative would improve brake feel, while actually stopping the car faster. Neither would reduce mpg. As keith said even if it does get more sensitive it would be such a small percentage of the time to not be significant. I'm sure someone will attempt to measure it, and I would bet the deviation would not be statictically significant.

Then again when I pass gas I think it smells like flowers. There are those that spread some fud that people were making up the defect. And these people included fud that it would decrease mpg or increase l/km. If you belive these people that it won't make it safer, brake better, then feel free to not get the fix, um, I mean fake software that only hurts your milage.

 

Wait, PriusPhile, you threw a tantrum over this whole recall thing, even going so far as threatening to start a class action lawsuit and now you're concerned about the hit to mpg?

Fellow forum members, why are you taking this person seriously?

 

Just another strike for lawyers.

 

How can do anything but keep moving forward with my brakes that don't work and my son's car with the sticky accellerator and nice new floormats.

I think they have to change that tag line soon.

It is my understanding that the software fix may increase the number of set bits in the ECU program. I'm worried about the impact of the extra weight. Perhaps someone with a really good scale can weigh their ECU before and after the flash.

In case anyone is taking this post seriously, this one falls under the same category as when W.C. Fields said: "The room was so small that Santa couldn't go 'HO HO HO', he had to go 'HA HA HA'." I'm not sure why "HA" is smaller than "HO", but I like it.

I called my local dealer to schedule appt. They took my name and number so they can call me back when the parts arrive and the techs are trained. It could had mpg's I may need to weigh my whole car before and after to check how much the new part weights.

 

Please be sure to tell us how much better the brakes work. I, for one, am really interested to know if you will even be able to tell the difference or if the feeling you would get during the brake failure is still going to be there.
