Critique my spark map! Looking for safety
 
https://cimg7.ibsrv.net/gimg/www.mia...6ebf247462.jpg
Do you think this spark map is safe? And would you have any recommendations for me? I am going to get it remote-tuned eventually but I just want to go out now and do some driveability/fuel tuning for now

This is on a 99' NB with a t25 turbo
Thanks!

If boost goes up, timing should go down. You sort of flat line a couple times. It’s otherwise a good start. Don’t let your rows be random. Calculate what 2 psi is in kpa, and go up that amount every row. 28 at 100kpa, down 2ish every 2psi row.

Agree in re-binning your table. Button in the bottom left of the graph will let you change the values, and interpolate between them automatically.

Set the top row to be just above the highest boost level you ever plan to run.
Then space out the rows evenly.

Cool, thank you.
