Electronic Stability Program: New Stuff from Prevost

Here's what they are saying:

Prevost Electronic Stability Program: A Helping Hand in the Face of the Unexpected

Prevost has gone a step further by introducing a new safety feature—the Prevost Electronic Stability Program. The system provides better vehicle control by reacting quickly in adverse conditions in order to help avoid potentially dangerous situations.

The Prevost Electronic Stability Program electronically compares performance models to actual vehicle movement, monitoring wheel speed, steering angle, lateral acceleration, and yaw to help avoid loss of control and rollover. This new safety feature assists the driver in reducing speed, keeping the vehicle in proper alignment, and reducing the tendency for the vehicle to slide. It also provides improved stability—a safety advantage in high friction conditions involving curves, sudden lane changes, and obstacle avoidance maneuvers.

They are a decade or so behind the times, but who's counting.

I'm waiting for traction control also to control wheelspin from all my engine's power.

And all of this is for just an increase of $100,000 in the cost of the basic shell. Whoopee. I'll never have to worry about that.

The Lewster figured that he would go for the Prevost Land Speed Record in the picture.

But you are supposed to do it at Bonnevile, not at The Great Outdoors.

Go Lew!

That brings up an interesting point: What is the top end speed of a Prevost?
Has anyone ever had one flat out?:eek: Bayley???

Here's where the organic fertilizer is going to be spread far and wide.

My 1987 8V92 with 3.73 rear gearing would go 72 mph, at 2150 RPM. My current coach with a Series 60 has a theoretical top speed based on the tach at 2100 of about 84 mph. The difference between the two is the gearing both in the differential and the transmission.

I have heard guys claim triple digit speeds. Let the posting begin.

The highest (unverified) speed claim was from Dave Wall at Liberty Coach. (Will not name the driver).

Eastern Texas, flat land, no wind, 93 mph in an XLV.

Probably not the best way to get fuel mileage, however.

Put me down for 85 mph. Of course that was after I installed a High Performace ECM and had the Boost turned up on my Turbocharger. Probably up around 600 H.P. at this time. Usually drive 62.5 mph. Just like knowing I have all that Extra Boost !

What is ECM?

How do you turn up the boost on the turbocharger?

Does Prevost install a governor to limit speed?

Perhaps more knowledgeable will reply but I believe ECM stands for Electronic Control Module.

The Detroit Diesel has a DDEC brain, which is programmed with certain operating parameters. I purchased a DDEC code reader on Ebay, and it's very interesting what kind of information is in that computer. There is indications that there are several "governor" settings which limit performance.

Some of boosting horsepower is simply a change in programming of the DDEC, while others require actual hardware changes. For example, I actually downgraded my engine from 500HP to 450 at the suggestion of a good friend who is regional tech specialist with DD. That change required no hardware, but DD did indicate if I wanted to go lower, it would require injector changes to match.

Jim,

I wasn't going to say anything about your ECM, but as long as you let the cat out of the bag have you noticed any additional tire wear from fast starts?

Just be careful because in reverse you can develop excessive torque.

Jon, I have noticed what appears to be more black on the concrete. With the Tag up I dont notice any difference. I guess the additional weight on the drive axle doesn't allow slippage. I was told by the Technician that did the work for me to start using my "back up beeper" while in reverse. Guess the extra torque is what he was referring to.
