LS1 with BS3 won't start hey guys, I'm having some trouble getting my LS1 to crank with a new BS3 install. I've tried with a crank reference of 350, 355, 360, and 370. I have spark and fuel. I put new plugs in tonight. After laying on the key for a little bit it'll sometimes try to hit a little bit, but never quite fires off. I did a BAL and i'm getting a grey dot while cranking. In the IO Status screen I'm usually getting some "bad sync" events. I searched through the manual, on google, on here, and other forums and can't find any info on the bad syncs. Sounds like it may be an indicator of the issue. Any ideas?
Also, one weird thing i noticed, my TPS won't ready more than 55% or so. i pulled off the sensor and did a sweep lock to lock sweep. still 55% give or take. I haven't had a chance to put a multimeter on it yet. I don't see this affecting my start-up though. i set the flood control to 30% throttle temporarily.

where did you get the big file you are starting with?
i can send you one i was running on a bone stock ls1 if you email me mightym0use@verizon.net
but that wont make the ball turn green, thats an electrical connection somewhere.. i think

Im pretty sure the ball turns green, but i can check when i get home.
The other dot that shows up after pressing the B A L keys turns grey while cranking Is it supposed to turn green too?
