0280155710 EBL INJ correction offset?

Ok I'm trying to set up the injector correction offsets for my 0280155710 injectors and I can't find a definitive chart anywhere . There's a few on here but nothing absolutely conclusive. I'm also looking for the minimum pulse width as well. Anyone have these on hand?

can try zero low pw but usually not a issue with 22s

I looked at that thread but there's 3 different charts and it doesn't say which is the definitive one

I think if you end up pretty close on the offsets, you can tune around that with the rest of the fueling tables.

In one of the threads, I discussed how I was helping a friend tune some 19 lb Bosch-III's that we couldn't find data for. I ended up using the offsets from my 30 lb versions and it worked perfectly.

Basically, if you try a set of offsets, and you're able to tune for them, you should be good. I had one instance where I absolutely could not get a set of Bosch-III's dialed in (before I knew about this voltage offset thing), no matter what I did with the fueling tables. After I learned about it, I went out and found my 30 lb's which cross reference to a Ford Motorsport p/n with an actual Ford datasheet behind them.

you wouldn't have those tables on hand would you? Lol

I actually cataloged a bunch of Bosch-III's into a spreadsheet during a different injector exercise I was going through earlier on. Basically scouring the various message boards and internet sites.

I'll post it here later today.

You ate a gentleman and a scholar sir! I appreciate it. I think it might be a good idea to make a sticky with all the different injector voltage offsets for future tuners. That would ab an excellent resource
