So my plan is to keep my car N/A right now. I have the exhaust and intake done, and I'm thinking of slowly gathering turbo pieces.

In the next few months I figured I would purchase the Rtek 2.0 (n326) and pull some fuel out in areas to get a little more power. Then I would look more into turbos...I have been reading over Aaron Cake's na turbo and he kept the stock ECU.

SOOOOO at this point my question is could I keep the Rtek'd ECU and add fuel to tune or do i need to get a turbo ecu/turbo pressure sensors etc?


thank you for taking the time to try and understand my incomplete thoughts.

 

You are better off going with turbo ECU and rtek when you add the turbo.. You'll need to get the matching turbo AFM and MAP sensors as well.

 

What is the actual difference? Aaron used a stock n326 ECU and a SAFC. I did not see him mention anything about changing the MAP sensor or AFM.

(I don't doubt you, just would like to know WHY its a better option) Plus I'm tight on monies

 

The NA ECU has no concept of boost. The NA MAP sensor cannot read boost. So essentially you are flying blind above 0 PSI. Not to mention the NA timing tables are probably pretty agressive for a turbo, especially if you turbo an NA engine that has higher compression. An AFC can't adjust timing.

Can you turbo an NA using an NA ECU? Sure. But you'll have much better results if you go with the TII setup.

 

^^^ Very Very true

 

Thank you for the replies
