Bosch 931 injector Info
Can anyone confirm which factory BIN is likely to have been used with the Bosch '931 LS1 injectors as I want to steal the Injector voltage vs Battery offset table from it.
Cheers,
Luke

Yeah I looked at those, I just cant seem to locate an XDF to go with the various BIN's that i have tried.

Try Dimentex24x7's XDFs from here http://static.moates.net/projects/0411/ with the 2001 VY Commodore bin from the bins thread (matching OSID).
Have you read the FAQ? For lots of information and links to significant threads see here: http://pcmhacking.net/forums/viewtopic.php?f=7&t=1396

Or download EFI Live trial version. It'll open a BIN file.

Ok cheers,
Had a look at those but I cant make sense of the table as it is voltage x vacuum x pulsewidth offset and the numbers are in the hundreds. Are they Nanoseconds?

Re: Bosch 931 injector Info
Edit: found some that make sense, and it looks like i may be able to use some of that and transfer it over to my $12p Injector Bias vs Battery voltage table.
Not quite sure which Vacuum range ill pick from but it might get me closer.

Re: Bosch 931 injector Info

If so, thankyou .
This info is not readily available. I have been searching on and off for days.
I have used the 40 KPA data from one of the VY LS1 Bin's and had to retune a lot of my VE Map to make it driveable again.
I will now compare your info to what I have put in before I do anymore datalogging/tuning
Im still on $12p but I was just looking for some reliable data on the Injectors I'm using as I was seeing a big change in AFR on the wideband when the Electric fans were cutting in and causing a voltage drop.antus wrote:Yeah its a different system. Which ones are you using?
funny how none of this seemed important back in the Kalmaker days... Im still learning
