Throttle Controllers: How much do they actually affect your fuel economy?
So I have one of those iDrive throttle controllers installed in my 120 Series turbo diesel.
It's got a range of different options including 'performance mode' and 'adaptive mode', but one interesting mode it has is 'economy mode'.
Now, I've read a range of reviews that claim the throttle controllers have little impact on your fuel economy regardless of the settings, and I would have believed that, until last week.
So on average, I'm getting about 11.8/100km in my 120 Series turbo diesel, Ironman bullbar, 2-inch lift, 33 inch RT tyres, bonnet scoop, roof basket, for the modifications I've done to the Prado my fuel consumption isn't really that bad, I can't overly complain.
Last week when I filled up I decided to put the throttle controller to the test, I brimmed the tank with premium diesel and switched it to 'performance 9' mode, now from a technical standpoint all this should really do is make the throttle more responsive, it shouldn't actually make that much of a difference in terms of the fuel that's been delivered.
Drove the car in the exact same manner I otherwise would, used the exact same roads, tried to eliminate as many variables as I could.
The needle was starting to get to the three-quarter mark on my fuel gauge, I usually fill up at around three-quarters of the second tank purely because it's cheaper.
398 km and it cost me $105, the week before that I managed to get just over 500 km and it cost me about $110, and that was with the iDrive turned off.
So having it on performance mode and eliminating as many of the variables as I possibly could, I lost almost 100 and a bit kilometres for just about the same amount of money.
Is it actually possible that the throttle controller could have contributed to this? Or is there a more likely scenario?
Since I last filled up I'm now trying it on economy mode to see if that makes any difference, once again I'm going to fill up at around the three-quarter mark to make it as far as possible, will be interesting to see whether my economy fluctuates again.
