Which stock GM vehicles use 42# Delphi injectors @ 59 PSI?
 

Need to copy the injector file because I am upgrading from 30# Accels (36# @ 59 PSI). Thanks in advance.

OK, anyone know where to get a 42# injector file?

http://www.marcintology.com/tuning/injectors.xls hope u hve excel

Don't have excel. Thank-you for the link though. I would just pull a file from the reference bins above, but, alot of guys tweek the injector settings in their tune & I need to start w/ the stock settings. Thanks again.

I believe the 2010 Camaro file can help you. They use 42# @ 58 psi.

Thanks, but, the injectors are 42# @ 43.5 PSI. So, now I'm scrambling to figure out if I can raise the flow rate table so that they'll run leaner. Thanks for the post, it is helpful. Was also able to open the xls file from Wntstogo100, but, it's a spread sheet that calculates flow rate from input variables. The program used only opens excel, it won't allow me to enter anything. Regardless, the tables need to be tweaked if there's even a chance to get them to work.

I have another thread asking if increasing the flow rate values will lean the now approx 50# injectors enough. As of yet, there have been no replies.

So download a copy of Open Office, its free and opens excel files and you'll never have a problem again!

just download Microsoft exel, it is also free :D

Math is your friend...

take stock injectors, divide by new injectors, boom, injector difference you need to multiply by.

Thanks for the replies. Finished all but WOT tuning yesterday. Injectors are tuned & working properly. Only A/F tweaking remains.
