BOSCH Fuel Injectors 0280155868

[mr.prick]

Does anyone have the settings for these injectors?
I found conflicting information on them,
anywhere from 36lb to 38lb and even 42lb. :nixweiss:
I've also read they are the same as BOSCH# 0280155811

This means they are 39.85/hr at 4 bar if my math is correct.

[mr.prick]

Link doesn't work.

It was an old url I had saved from LS1tech article.

The tech sheet said it flowed 34.51 at 43.5 psi, most of the aftermarket companies have flow matched sets that flow 36 lb at 3 bar, so it is often call the 42 lb injector for the lsx engines. The BOSCH# 0280155811 is know as the white top injector and was used in the the C5 for racing. The GM part# is 24508208.

[mr.prick]

So the offsets and flow rate will be in an ASA .tun
Now to find one. :sneaky:

I also found this on the ASA tune:

[mr.prick]

The .pdf is somewhat useful.
It shows the flow rating with N-heptane, which means the data is not perfect.
I got the script in that thread but I would really like to see an actual ASA .tun file.
The one I found does not seem to be right {B4001}.

Buy the DVD! :moon1: :pokey:

[mr.prick]

What DVD and why buy anything when all I need is an ASA .tun?

[joecar]

Howard is being tongue-in-cheek-funny...:hihi:...he's wearing flameproof undies.

[hquick]

Did you ever manage to get some more information on these injectors? I'm trying to use the same ones.

[mr.prick]

Yes I did and I added some stuff too.
This stopped the rich decel in open loop.

Ok, thanks for the data, I added a link in the "Collected" thread. :cheers:

[SirNemesis]

Thanks guys :D

[mr.prick]

P.S. :doh2:
The 12212156.cax needs to be used for {B9021}. (http://forum.efilive.com/showthread.php?9143-.cax-file-updates)

[monzaaddict]

what program are you using to open/read cax files? I am using windows xp and am getting a message that windows cannot open the file.

[joecar]

Use Notepad that comes with Windows (i.e. go Start->Run and enter in Notepad.exe).


To set Notepad as the default .cax viewer/editor do this:
in Windows Explorer (not Internet Explorer), go Tools->Folder Options->File Types and define a new file type for .cax and for Opens With specify Notepad.

[monzaaddict]

thank you.

These injectors are used in the ASA tune. The GM tables are available in the ASA tun...offsets etc.
There are both a 1998 ASA and 2000 ASA/World Challenge Corvette tune in the tune file repository - under Corvette ASA. (http://holdencrazy.com/EFILive/stockTunes.php ).
Good Luck. :D

Is this data correct for a 4th gen F-Body that has 58-59 PSI fuel pressure?
