Im just working on getting my idle right on my new diypnp.

I'd like to change the lower 4 columns on the spark table (currently 700, 1300, 1800, 2900) to add a 500rpm and 900rpm columns.

I presume to do this il have to remove to other rows, is there any preferred rows to remove? When i add the 900 row, is it just a case of selecting the 700,900and 1300 rows and let tunerstudio interpolate the 900 row?

Also how should i go about filling in the 500rpm row?

Thanks
Mike
