After each 1/2 hr of tuning efi your keyboard should pour gas on your hands and squirt carb clean in your eyes. Then it would be no different. Lol.

does holley have shift anticipation,mefi 4b's do and makes it easy to help control the shift into gear.this along with proper fuel smoothing and advanced timing.

If it does I haven't used it or needed to use it. It does have other Custom Idle Control settings that adjust for load but since it's not made for marine specific so they don't call it shift anticipation. I really haven't had to use it yet though because I didn't have any idle or shift issues on the ones that I've tuned.

My engine is 502 mag efi, that engine iac is so slow that it not help nothing. Late idle timing make engine idle slow, so you put more basic idle air in and engine idle good. When on gear, advanced timing with little bit more air gives more power to idle on gear

BINGO BINGO, works perfectly I also raised the Park up to 60,

We got it tuned great this past weekend. I was using a 32P bravo. I am putting on smaller pulley on blower and putting on the MAX5 34P prop for some speed tuning etc.

Bingo? I didn`t understand what Ksalmine was saying, so what did you do? .. more idle air, and or fuel mixture will never act fast enough to prevent a stall, only timing will. so enlighten me please

removed idle spark control, raised timing a few degrees and i set the iac stepper to fast. I also flattened out the fuel in the idle area.
