Dear Roby,
... how would you relate our pickup problem.
Dear Jairaj,
It's a fact that the torque delivery of this engine at very low RPM is horrible in this car. It stalls about just anywhere. The one and only Xcent review which bluntly has stated this (terrain handling, stalls on setting vehicle to move) fact is TAI. Others just skimmed over it saying the engine is not for enthusiasts, which is anyway the case with most of the cars in this class. The fact is that, a sedate driver too is caught in this problem in circumstances like this.
Being an owner of 1st generation i10 (1.2L), I can confidently say that it was better by at-least a factor of two. But the downside was that my i10 gave terrible mileage - perhaps it gave me just about 14 Km/L in the best of highway runs. Xcent gives me not less than 13 Km/L in all circumstances, and in highways it is consistent 18.74 Km/L. So they did something to the system (Gear ratio / ECU mapping) to extract this out. But what I lost in that is, the easiness to get out of such tricky situations.
If you look at this, it is the 2nd gear which gives up. Put it on 1st and you can actually be on that and drive up to about 40 Km/Hr. It is just that 1st gear which can take that engine RPM higher (Above 3000 RPM) on a demanding condition. Being in 2nd gear, Xcent just doesn't honour it. I've learned to push this to 1st gear when I know that I would need to fly off in the very next moment. If that means first slowing down to a speed where you can actually shift to 1st, it is worth the move. This car can be driven only this way.
Perhaps an ECU remapping might help, but service centre won't do it and will void your warranty. And if this is all about a taller gear ratio, then I don't think ECU remapping would actually help. Best bet is to get used to this, as I have now become. It is slowly becoming a normal routine for me, and I am starting to have my original i10 easiness back - but the occasional stalls leave me grinding my teeth.
Now another twist is that when the car is fully loaded, then this engine is quite underpowered for the load. But that mostly affects only highway speeds that I can attain, and overtaking vehicles. It doesn't seem to affect the initial take off much.
