No issues and no CEL's. I would leave the first setting on E and turn it up to 1 first before you go any further. Luckily our cars have a pretty good security system and the engine is protected if it senses too much boost, too lean or too rich. I have used these for years on different cars. Had a JBD on my 335 diesel and then Racechips.
S2 setting makes much smaller increments than S1. Look at the screen shot of BCLK55 couple pages back. He is still in E/2 and did 350 hp and M5 worthy TQ numbers.
