When I wrote the current tune for my set up I used the data from ID for the return fuel system. Naturally assuming that since I'm return now it was the way to go. The car runs and drives fine for the most part. I started thinking about the other guys that can use injector files and that they must have the returnless modifiers still. So just for S&G I loaded the returnless info into my tune. I didn't change the slopes or break point though.
Man, the car didn't like that. The STFT's went nuts. Bank 2 was ok, but bank 1 was max lean. When I revved it, it just shocked and sounded horrible. I went back to my old tune and it was fine again.
I still have the FRPS in place and I'm still using it. Why did it run worse with the returnless modifiers?
