you may be able to, depends how your car is set up, each one is different.
Your SPS settings wont read on lemmiwinks mate, so whatever timing your set on, lemiwinks will still see 0.00 to start with.
Jabba use lemmiwinks when they get customers wanting timing increased from FMIC or DP or something.
I found it best to leave it alone, you will hit a small number where you will see huge CF's, so small incrememnts till your seeing 2/3's in the pull.
first time i read my ecu with lemmiwinks it read the timing as it was set which was -2.25 what jabba had set it at not 0.00. now set a +2.25 with the help of water injection
