Bosch III injector offsets

I'm using Bosch III, 32# injectors from Injectors Plus in my 383 SBC.
The injector ID numbers have been removed.
I called Injectors Plus but they were unable to find the offset bias numbers for these injectors.
Anyone out there have any offset numbers for Bosch III, 32# injectors that they would share?
I would certainly appreciate it!

Ahhh... a subject near and dear to my heart!

Here's what I'm currently using on my 30 lb Bosch-III's. My guess is you can start with that as a baseline and fine tune from there.

In any event, do NOT expect to just change the injector constant and voltage offsets and then have it running perfectly.

Re: Bosch III injector offsets

I have seen these offset tables and the other posts in my research. Drive-ability is my main goal as this is a "Saturday night cruiser" only. I use is Rbob's EBL-P4 which is a system I really like for my application. Originally 36# injectors were recommended to me but I felt these would not give me the drive-ability I wanted. BLM's stay in an acceptable range (which obviously varies on any given day). I've just installed an AEM wideband but the weather has not cooperated as yet for new VE learns.
Thanks - I do appreciate the response!

Re: Bosch III injector offsets

I had a heck of a time finding something for my MSD 50's, that information seems to be classified or something.
