Default Need a 42# table

Does anyone have a table for the 42# Lucas/Dephi injectors?

I am nervous about simply scaling the table as I believe the disk injectors have different response characteristics than the current pintle injectors.

As an aside, I was astounded today when I finally got a log with the 370 inch motor and my 30# SVOs saturated at 4500 at 12.5:1 and it went as lean as 15:1. Luckily nothing broke ...

I used that table for mine earlier today... no dice.

Got idle alright, but when I try to give it gas it gets WAY lean and sputters out...

Anything I should go look for?

ok, so I went back and took out some of the other stuff that I had done but left the injector table alone.

Looks like that took care of my problem, that injector table looks good from my end!

I used a slightly different table in the end. If you're going up to SVO 42's, then this table is close enough

ok I think I changed the right one is it under fuel control- flow rate vs. kpa. Then copied and pasted the above values into the slots . Is that correct?

Just curious....if the fuel pressure is stable , why isn't the number constant after it's converted for the proper pressure? Like 48.50? What's the factory constant for factory injectors?

stock fp is 58 psi . I may be wrong but i think the vacuum of the engine at different times changes the flow just a little.
