had recently installed an ARB turbo timer, this is the second hilux i've had with a turbo timer, first one, on my 05 hilux, was a no-name brand and work perfectly. (was also 1/3 the $ of the ARB one). Now the problem i have with the ARB one is you cant lock the doors with the remote until the engine shuts down......kind of defeats the point of having one if you have to hang around and wait for it to stop idleing. Was installed at my local ARB dealer and when i rang him to see if he had wired it up wrong or if it was faulty, he said "yeah i know and the D40 Navara does the same, were looking for a fix....". Have others had this problem wiyh the ARB unit?
