The programmer would code the logic before taking a 2nd sip of coffee. Compare this with the cost of designing the gearbox changes to mount a switch, drilling and tapping the switch hole in each gbox, purchase and fit a switch, wiring loom extras and fitting it - no contest in production costs.

Perhaps fit a switch to the low range switch circuit so that the engine ecu doesn't know its in low range, but as stated above, the throttle could use different mappings and thus this solution be unacceptable.

a 2 second think makes me believe that as anti stall is only in first low that there should be a switch on both the box and the case. bypassing the gearbox switch would be the way to go as if like the TD5 the Puma donk remaps the throttle for low range work disabling the case switch will also offload that feature.

Nope, the only switch on the gearbox is for reverse,

Yes, there are 13 different engine maps, 6 high, 6 low and one reverse,

making it auto can confuse it !

I have had my 07 for over a year now and have had it up and down in some very serious trails. The anti stall feature is brilliant! It does take a completely different style of driving though. Insted of using the accelorator, let the ECU do that, have one foot on the brake and one on the clutch. If you need to slow down a little bit then just ride the brake but if the obstical is to big to hit at 1000rpm speed then ride the clutch, the anti stall will still kick in and you can go as slow as you like. It does take a little practice as it is very easy to apply too much clutch and find yourself tearing backwards off the obstical usually at a great rate of knots

Believe me they did do their home work and it is a great feature just practice casue it is way diifferent to any other technique you've used before.

Cheers,

I"ve also found the anti stall works in reverse as well. When you have it in low reverse when backing a trailer, etc. If your just letting it idle along it keeps reving upand increasing speed. Again just a practice thing i guess.

I agree - but I have never owned anything else so I didn't have any habits to alter - I have got used to using the Puma anti stall by just using the clutch and brake and I totally rate it.
