Thinking of getting a stage 1 remap and trying to understand what will actually change. The tuners all say the same thing "more HP", "more torque", "more power", "faster response" and I get all that but how does it actually translate into the actual driving experience?
For example, using simple numbers and metrics let's say my unmapped 1.2 turbo petrol auto currently does this when driving normally with 40% throttle:
- changes from 1st gear to 2nd gear at 3.5k revs when it reaches 10mph (it takes 2 secs to reach 10mph)
- changes from 2nd gear to 3rd gear at 3k revs when it reaches 20mph (it takes 3 secs from 10mph to reach 20mph)
- changes from 3rd gear to 4th gear at 2.5k revs when it reaches 30mph (it takes 4 secs from 20mph to reach 30mph)
So that's a total of 9 secs to go from stop to 40mph.
Now, once remapped, it gains an extra 20 BHP and 40 NM torque. How will that change the way it drives?
1. Revs stay same but it reaches the gear change point at a lower speed (e.g. changes from 1st to 2nd gear at 3.5k revs but at 5mph instead of 10mph).
2. Speed stay same but revs lower to change gear (e.g. changes from 1st to 2nd gear at 3k revs instead of 3.5k revs but still at 10mph).
3. Both revs and speed stay same but the acceleration is faster (eg. now takes only 7 secs to reach 40mph).
4. Nothing changes but only need 20% throttle instead of 40% to drive it the same way (so more responsive).
5. Different combination of any the above (and what would this combo be?).
Hope this makes sense, any advice would be great as it'll be my first remap so all new to me. Thinking I might go with a Bluefin over a stage 1 as quite like the idea of being able to put it back to stock just in case.
Cheers,
