Fouled spark plug?

[bjk_typhoon]

Driving home last night I recieved an engine code 45 (running rich). I have been having issues with getting my Ty to run right after my build. I am still in the process of getting my datamaster but I am fighting issues with getting my Phil Long 50#er chip to work correctly. I have been swapping between the Phil chip and an old ART Pitbull chip. I know I can back off my fuel pressure (currently set at 40psi) but I am fearful of KR under acceleration. Any way here is plug number 1 after about 800 miles. Do I change them out or not?

Re: Fouled spark plug?

If you are running an old ATR chip with the 50# injectors that is a problem right there.
Last I heard ATR didn't make a 50# bin.

It is probably dumping way too much fuel because the injectors are so much larger and the chip doesnt know the difference.

Believe it or not it runs better on the ATR chip than the Phil chip. Yes I know that there are issued that need to be corrected but on the Phil chip it loads up so bad it will hardly run.
