If I am running full sequential fuel, Should I be 1 squirt??

[redmist]

right now I noticed that my tune has fueling setup as 2 squirts per cycle alternating. I just started the car for the spring and am going over the tune and was wondering if I should have the fueling set at 1 squirt simultaneous??

This is on a fully sequential tuned port v8

i think it is pretty much up to you. i know when i had my ms1 my 351 windsor idled better with 2 squirts vs. 4 squirts. now i have a ms3x also with 2 squirts alt.

Would running it in 1 squirt help, or harm?? I like the idea of a simple single squirt, but don't know for sure. My understanding is that 1 squirt alternating is only available if I am true full sequential. Is that correct??

[racerron]

1 squirt is for simultaneous.

[kaeman]

according to the tuner studio ms manual, sequential should be set either 2 squirts alternating or 1 squirt simultaneous. (section 8.1.1)

[racerron]

right!

My understanding is that in "full sequential" one squirt is the forced condition; it doesn't matter if you have 1, 2, alternating, or whatever, set.

I run 1 squirt simultaneous on my fully sequential 4-banger, I tried to do that with the Toyota V12 and it just poured fuel no matter what required fuel was set to. Had to run it at 2 squirts alternating fully sequential, runs perfect. I won't claim to understand the nomenclature, I just go with what works.

When you are running sequential, you get one squirt per channel per cycle; when you're running semi-seq, you get two. Period. Doesn't matter what the settings are in the Engine Settings tabs.

The confusion comes in when because the AMOUNT of fuel in those squirts is still determined by the entries in those tabs. There has been some discussion here between Jean, James, and Phil about simply greying out those entries, and having TS do the math based on ONE squirt (seq) or TWO squirts (semi).
