Marine Manifold and idle tune...
Hi All,
well...I'm stuck tuning idle for the moment as the rear diff is still in bits.
Anyone care to have a look at my current tune and a log?
Running 42lb Green top Bosch's and the Vortec 58lb's of fuel pressure (standard reg).
Any comments/advice would be greatly appreciated.

YOU ONLY NEED TWO TOOLS IN LIFE - WD-40 AND DUCT TAPE. IF IT DOESN'T
MOVE AND SHOULD, USE THE WD-40. IF IT SHOULDN'T MOVE AND DOES, USE THE
DUCT TAPE.
IF YOU CAN'T FIX IT WITH A HAMMER, YOU'VE GOT AN ELECTRICAL PROBLEM.

IMO
you need to fix you PE enable% {B3616} and PE AFR ratio {B3618}.
especially if you are FI.
Hummm
PE is not in the equation at the present as it's idle tuning in OLSD.
What where really after is some good insite into changing injector size and the effects of doing so.
I guess there's not to many people that have gone from the crapy Vortec poppets to a set of 42's.
Couple of things that interest me are the effects of the following parameters.
B4003
B4004
B4005
any takers?

Howard, idle tuning is not my forte, but I sent you a pm regarding trans. throttle kickdown tables.

These are the latest tune and log from this morning.
I realized yesterday that the TB% was at 0.4% so I adjusted it back to 0%.
