Tuning / Mapping
If the mapping table goes x rev means x injection ok thats clear...
but if i hold rpm steady and i adjust mixture rpm will rise or decrease not?
wich will result in falling in another cell value in the table not??
If you go steady 3000Rpm and i increase BHP the only thing we should notice is that i could lose a bit the accelerator not?
Also how much bhp is gained with a powercommander??
sorry for the amount of questions
Tks

It's a 3 dimensional table of RPM and engine load (MAP or TPS) which gives the required fuel correction.

If you are using a dynamometer they can automaticly hold RPM at a fixed point by varying the load. Bit more difficult if you are doing this on the
road.

By backing off the throttle to maintain RPM you will be changing the MAP or TPS reading, so you will move to another part of the table. You really
need to adjust the engine load to hold the RPM steady (i.e. find a suitable hill, apply brakes etc.)

sow in fact
Top gear and then use the air resistance..
i thought that the dynometer was just a Flywheel with x mass wich is accelerated. measuring the acceleration the revs and its mass, the torque should
be possible to calc.. and then with the rpm we have the horses..

Almost right, but they also have a brake so you can keep the revs constant for varying loads.
