Thread: Disabling the weird Puma revvy thing.

There is a tech bulletin for this, it involves a software download to the PCM.
Only became an issue on the 2.2 engines.
Makes a big difference when it is fixed.
Hope this helps

LR now say it is normal operation and have taken down the bulletin,
But downloading the latest software to the PCM fixes it.

Does not sound like normal (correct) operation to me?

I am the same, mine does not kangaroo but it's also a 2.4.
The FBW is unresponsive to a degree to help reduce kangarooing over rough terrain. The engine over run when changing gears is a bit hard to understand, but on mine only happens in high range. It exaggerates the effect if I bugger the timing. However it seems just 1/4sec more off the right foot timing before change and you've overcome FBW changing.

Thanks, but which software? What is the PCM?

I can only speak from a test drive perspective (this morning)... but it was a long drive in a variety of traffic, highway, low speed, steep hills etc and I didn't notice any problem whatsoever. I did hear a little over-rev once or twice, but certainly nothing to affect the drive.

Cheers,

You're welcome to have a drive of mine and see what you think.

I really am quite curious as to exactly what you guys are experiencing. Obviously it is not a figment of your imagination, as you are not alone in your complaint. Hope I wasn't implying that I don't believe you... if so I apologise as that was not the intention.

I certainly would not say no to another drive of a Defender (but yours may be just a little far out of the way to justify the road trip).

No, I didn't take it that way at all, and the offer is genuine. It interests me that some do it and apparently some don't. If you were to drive mine smoothly through all gears and say at the end of it that you still didn't know what I was on about, then I'd probably stop whinging and go away and work on changing my driving style. But I doubt you would. Likewise I'd be interested in driving another one for which the owner claims there's no problem. Maybe this thing suits some driving styles and not others. It doesn't suit me.
