i just converted my car to a standard but i left my auto ecu in the car and i was hoping for some input. should i change the computer to the manual ecu or should i get a product like the S-AFC II to get the fuel maps id like for the car ? >>

Your auto ECU can handle the coversion, But reverse the swap and its a no-no. Unless you have modded your car at all the SAFCII wont do anything.

if you have a wideband 02 sensor and a dyno to tune the safc2, go for it.

i currently have one with my turbo setup and i have donw some basic tuning.

dont mess with it unless you know what you are doing.
