Injector offset table for Lucas 42's
 
Chris has given me some links and such to injector offset but unfortunately at this point it is all greek to me.

I was wondering if anybody already has the table built I could take a look at to give me a good head start.

Thanks in advance.

I posted this table and it includes a conversion for the Ford 42#/hr injectors using the factory ford offset values, converting to LS1 values.

http://ls1edit.slowcar.net/injectoroffset.xls

it can be easily switched to calculate the offset for the Lucas 42's - you just need to change the offset values on the second page, and the first should update properly.

http://carprogrammer.com/Z28/PCM/Injector/injectors.htm

has a couple of offet value lists, in LT1 style.

I still don't understand it.
How do I know what to change the offset values to?

And did you mean change page 1 so it updates page 2? Page 2 has the complete table like it looks like in edit.

I use stock offset values for a 98.
I run a vacuum referenced feul pressure regulator.
45psi at idle and 55psi at wot.
I use 6.1 gms/sec flatlined across the table.
Works very good.
