Quick question (depending how you look at it.) So what is the difference between Syvecs S8, proEFI and Cobb/ Ecutek? So once you have Syvecs you don't need cobb or Ecuteck? I know alot of the guys seemed to be up grading to Syvecs on the High hp builds so is it essentially a different Ecu and Cobb or ecutek being a "tune" on the existing ecu? My bad i'm just a bit confused.
^^ The Syvecs is a replacement ECU. The Cobb / Ecutek is just a flash using the factory computer. The Syvecs gives you a ton more options when it comes to flex fuel and fine calibration. It's the difference in a set amount of fields (ecutek/cobb) vs the whole ecu (Syvecs)
