hello, i am new on this. sorry for the dumb questions. what does the comptect esm do? can i run the SC without it? cause i dont have one. people told me i can get vafc , neo to replace it? why i need to get those to make the supercharger work? thanks

 

you need the ESM to hide boost from the ECU or it will throw a code. all it is, is a voltage regulator that is set at 2.93 volts. but it is a must if u run boost without the emanage or EMS.

 

so will the apexi neo do the same job?
