I got a ticket for doing 84 on that Highway last year. It was an expensive ticket, too. Now I likely wouldn’t have been pulled over at all. Oy.

I think you’re talking about a particular 1999 Eldorado, though this article doesn’t specify the year of the car: http://www.caranddriver.com/reviews/mosler-twinstar-eldorado-specialty-file

“Brake power” is only part of what keeps the car from launching forward in this situation. It’s also weight distribution that’s affecting relative grip between the front and back.. In a front engine, rear wheel drive car, like this one, the weight of the engine over the front tires generally means more weight is…

Are you sure that’s all it takes? Or is the data cached on some kind of flash media that needs to be cleared? Or is there a local battery backup for the data that needs to be disconnected inside the NAV computer?

Not all “hard reset” operations are as simple as “Have you unplugged it and plugged it back in?”

It’s a software bug that prevents the system from fully starting, which prevents it from getting new data, which prevents it from replacing the old data and fixing itself. That requires a hard reset to clear the errant data.

See, I’ll do kind of the opposite. I often put my SC400 in to snow mode. It keeps it in higher gears and won’t shift down as much, plus it pulls back the throttle response bit, just enough to keep it from lurching while still allowing WOT as soon as I floor it. Makes it -very- docile for normal driving, but I can…

Yeah, these are all fun and joy ‘till the starter goes out. It’s under the intake, which is under a ton of wires, sensors, and 8 injectors. Plus the bolts are in the back, right up against the firewall. I’ve done it, it sucks.

There’s some truth to the speedometer calibration statement if it’s simple needle placement. My Lexus is off by about 3MPH across the dial, at least as far as I’ve measured against GPS and a couple of friendly law enforcement radar guns.
