hey guys Im a newbie,and need some help.Im going to install a set of 42 lb bosch injectors on my LT1,Im using Tunercat and was wondering if the only thing that I have to change is the injector flow rate in the constants table to 42 to make them work.If so could someone let me know,or if not please help me out on this one.

If you're using a speed density computer, yes.
If you're using a mass air computer, then you'll need to change the injector offsets as well.

 

Im speed density right now with the stock pcm,but I plan on installing a supercharger,and hooking up the MAF in the near future,any idea what the constants need to be changed to?

thanks...Keith

 

Sorry, I've never seen offsets for a 42 before.

 

anyone else??????

I found the offsets for Lucas 42# injectors. Not sure if they're the same as the Bosch 42's or not...but I'm guessing so.

Check out Christian Millards site at http://carprogrammer.com/Z28/PCM/Injector/injectors.htm

 

The voltage #'s do not all match up with my 97.LT1 file. I have some voltage #s that that chart does not have (Example18.4) and it has some voltage #s that I do not have.

I need the offset #'s for 42 Lb lucas/delphi .009 injectors. Anyone know where to get thesE?
