Hey,

Tell me what you think.

If we start with a blank timing map (because we want to or because we have no choice) would it be right\smart to tune as follow ?:

set base timing

set all map to 10-15deg

ramp run through all the rpm range (or part of it)

then add 5 deg

ramp run again (with det cans all the time)

see where you pick power and where not

where you did not pick power back 5 deg

where you did pick power add 5 deg more (on high rpm and boost we can use lower increments)

repeat

Of course with paying attention to knock and backing down a few deg where knock is present.

Fuel tuning as needed.

Practical ?

Slow ?

Inefficient ?

Dangerous ?

other prons and cons ?

Thanks

Elior

This is essentially part of the technique presented in our practical tuning course. You've skipped the steady state tuning part though which I'd suggest is essential if you are on a dyno as it builds the shape/trends into the table before you start performing WOT ramp runs.
