Its true ....... and on the route I have chosen to go to CT I will be doing around 200 odd kms of dirt road through the Northern Cape also.....  |

Jah boet. And now that the temperature is in the 30s, I can have the top down in the Saab  --

Back to the topic at hand - if you are increasing the torque by remapping, what are the negative / unintended consequences for the drivetrain? Can the gearbox, clutch, transfer box etc. manage the increase in torque, or will it reduce their lifespan?
Secondly, by remapping an engine do you increase the operating temperature / cylinder head temperatures of that engine? That would be a huge no-no in a climate like South Africa, for me at least. I do have an intercooler from Allisport on order because the standard intercoolers are not suitable for our conditions, in my opinion. It may be fine and dandy remapping in the UK, but our ambient temperatures here in summer are 30+ celsius. My main interest lies in overlanding, therefore I don't want to compromise the vehicle's reliability. Sorry for the semi-hijack, Bruce, but I know you're have the same interests, so probably share the same conerns. |

Hi Rob, Definitely not a hi-jack and definitely pertinent questions. I too have the same interests. |

I've tuned many 2.4's in some very hot climates around the world.
The best case of temperature related problems have been in the northern territories of Australia, with 110's pulling very heavy trailers over hills etc. It would seem that the thermostat doesn't allow adequate amounts of coolant from the radiator, into the engine, and so the engine temp rises above safe limits, and the engine management then cuts power to stop the rise in temps from escalating. You can modify the thermostat to allow a higher bleed rate, which actually works well to control this, but maybe fitting an uprated coolant radiator could also be an option. CHT will always be higher on a remapped car, and it's the job of the cooling system to keep them down. However, I do take care that what ever remap I make, is tailored to the climate, fuel type, and work load that is appropriate for you. Drop me a PM if you want to discuss anything else.  |

If I dont change my driving style after a remap in theory will fuel consumption improve?

It should, but it would depend on whether you're doing short runs where the engine and transmission is always on warm up, or long runs. Difficult to put any kind of a figure on it, but it should be better.
Another point is I will always set limiters to not exceed safe torque limits, unless I'm told otherwise!  |

I'd say that means that it won't be tuned up to the eyeballs, so all the standard drivetrain bits won't break as soon as you put your foot down. By the same token if you have aftermarket drivetrain components, intercoolers , performance exhaust etc then I'd hazard a guess that you could have it tweaked up a bit more to gain the maximum benefit from those components and the remap.

There is no way you will be able to resist dicing with the GTIs at the robots. Ok, maybe not the GTIs, but most certainly the Cruisers! Bruce, all things being equal, your fuel consumption will definitely improve, especially on long distance runs since the engine is now operating more effeiciently. -- 2010 Defender Puma 90 + BAS remap + Alive IC + Slickshift + Ashcroft ATB rear 2015 Range Rover Sport V8 Supercharged

I feel I can add to this through personal experience.
Here the average temperature during the summer is 35-40 degrees C. I am running an Alive map, with iTg filter, and full Alive exhaust system. NOTE: I am running standard intercooler and drivetrain. After 20,000 miles in these conditions (after 20,000 in Germany, Austria and UK) I have had only one problem and that was where the rear diff was getting noisy. Everything else has been sweet as a nut. With the map I tend to drive at approx 20-30% throttle and it still pulls harder than when I was on full throttle with the standard tune. For this reason the Turbo will be working less and therefore intake temperatures will be less helping reduce the engine temperatures. Even towing 2.5 tons is no hassle. The temperature has never risen above half and the vehicle has never gone into 'limp mode' An intercooler is next on the list of things to do as I am conscious of the possible temperature issues. Especially with Roo-bar, lights and winch: Click image to enlarge I am now consistently getting 29mpg compared to only 26mpg without the re-map. I will never look back and won't be taking it off when I do my 15,000 mile overland trip next year. Glyn  :sheep:
