Hi, this might be a stupid question but I bought my fd3s with the Power FC already installed. I have the Stock ECU, is it safe to unplug the PFC and put in the stock ECU and take the car for a test drive? The mods to the engine etc. are minor.

Thanks

 

What do you mean by minor?

 

exhaust. intake, and intercooler

 

no its not safe anymore

 

It depends on what your definition of a test drive is.
As long as it does not include full throttle it will be safe.
But if you have some other mods not mentioned, the car might not run as smooth.

 

Can't be worse than what I did. I ran full throttle a few times with more mods than that on the stock ecu, on one rotor.. And still pulled harder than my rx8..
