Hey, I am trying to make a choice on which rtek to get. If this is able to work the way I think it does it should be the right choice for me. I just want someone that know this product 1st hand to clear up my misconceptions. I read that on the Rtek 2.1 for s4 N/a the fuel map is on a boost vs rpm table. Does this mean that the n326 pressure sensor will now be able to read boost, or can I possibly use the n318 pressure sensor in its place, even though I'm using the N/a ecu (which now has a map for boost)? Kind of like the idea of swapping out a 1 bar sensor for a 2 bar sensor.

 

You must keep the ECU MAP and AFM from the same car. If you are using an NA ECU, you need to use the NA MAP sensor.

If you have a NA to turbo conversion, it's best to change the ECU, MAP and AFM to the turbo versions.
