Plug N Go Throttle Response

[tadpole]

There have been many threads regarding the slow acceleration response/hesitation after slowing down at roundabouts, intersections etc then trying to accelerate. Many have comented that it is an inherent characteristic of the Discovery and the hesitation cannot be eliminated.

I have picked up a brochure for a product called PlugNGo which is installed between the accelerator pedal and its control module without affecting the ECU. There are a number of settings available to improve throttle response.

Has anyone has tried this product.

The website is www.plugngo.com.au

Do you understand how these work?

Besides the fact I personally wouldn't trust a gizmo like that with the electronics in my D4

Or the fact their web site seems to think that Land Rover is one word (Landrover) :angel:

They don't appear to list a model for the D3 or D4 anyway. ;)

There may be some benefit if the throttle output response from the pedal can actually be altered by the plug n go device so that the vehicle sees more throttle earlier, but I do wonder if all it will do is make the throttle too touchy.
If tadpole is going to buy one I'd be curious to see what the results were.

The problem is not with the Engine ECU but the gearbox ECU - the pause is the gearbox staying in a higher gear and not changing down straight away - put the throttle down and the gearbox ECU thinks to there is enough power to stay in the higher gear but there is not and by the time it realises it needs to change down - that is the pause. Try driving in command shift and you realise it is not turbo lag or poor throttle response as it is not there.

One way to trick the engine ECU is to initially not to floor the throttle but go to 3/4 power - the gearbox ECU realises there is not enough power and changes down and off you go and can then use full throttle - no delay, full acceleration.

The PluNGo concept does seem an attractive simple product to overcome an annoying feature but I would never be the adventurous one to spend $350 on something I had significant misgivings about. I realy appreciate your input but was not about to purchase without supportive comment from this forum. If the solution was this simple I assume all vehicle manufacturers would change their software.
The website lists a significant number of vehicle manufacturers and I doubt they all need such a product.

You could try putting terrain response in "Sand" mode, so you get a much more responsive throttle that can also go to 110%, and also put transmission in "S" mode so it delays shifting down when you are slowing.

Sand mode!

Ok let's add some info....

The delay is not Turbo Lag...
Garry is in the money once it's moving..

The delay for launch is as described by the difference between Sand mode and normal.

It's based on a traction behaviour and a trans ecu behaviour. The torque output is controlled to prevent loss of traction and wheel spin - as Garry mentioned - FEED the power on and it will take off, stomp it and the vehicle steps in to prevent wheel spin..

Sand mode removes some of that control...


This stupid device that people keep coming up with CAN NOT remove the flat spot...
All I does is intercept and change the algorithm/ curve for the throttle pedal..

Put simply - making it MORE sensitive will make the lag WORSE...

I have found that if you clear the gearbox adaptations, the throttle (gearbox) is more responsive/removes the flat spot.

I would'nt use anything electrical unless it was Land Rover specific and a proven product(ie)LLAMS, BAS and DPL re-map, Traxide and so on.
