Injector update

[iso221]

Long time lurker first time poster, I have a question for the community I have a 2002 GMC 2500hd 6.0l I'm looking to update my injectors from 2 hole to 4 hole without doing a computer tune I've googled and googled and AI contradicts itself every search what part numbers am I looking for. Also it doesn't need to stay multec if there is an ev6 option out there that I don't need a tnne I am completely down with that. Thanks for your time

Why is my question?

 

Any change in injectors requires a tune. Unless you are going back with the OEM part number or a newer part number of that same injector.

 

Any size difference or type difference like the EV6 style injectors all have different injector data for them. And there is no EV6 injector that matches the factory 25 lb/hr size that your truck comes with. I've been messing with these trucks and tuning them for a long time and what you trying to do doesn't exactly make sense to me.

Because single shot injectors are ancient and multi hole injectors provide smoother running engines and sharper throttle response due to the fuel being atomized better..the best lead I have is a 24lb blue top injector almost everything matches up but the injector will put out about 26lb/hr which is just outside the gm threshold.figured id ask here to see if there was an absolute answer

While it may be true that multi hole injectors atomize the fuel better, it ain't going to make a difference on your stock truck. I have USCAR EV6 50lb/hr injectors in my turbo 6.0 foxbody with stock cam/valvetrain, I didn't notice a smoother idle or overall driving with just the larger injectors.

 

Even if they put out 26lb/hr at 4 bar pressure like you need, all of the other data won't be the same as the GM data. The offset vs volts, short pulse adder, min pulse width and flow rate data all need to match the injectors installed, no way all of that stuff would be the same.

If you would read instead of trying to flex your big bad fox body. I wasn't talking about larger injectors was talking about going from a single shot nozzle to multi hole nozzle. Which it's common knowledge that they provides better idle quality and better throttle response due to the better atomization. But hey if were whipping dicks out I noticed a huge difference in thottle response when I switched out my factory single hole injectors on my 88 fox body

Okiee dokie there bud, way to take things to the extreme.

 

I guess you missed the whole point and take things way to serious. I installed different EV6 style injectors that just so happen to be larger in my car running the same LQ4 engine and with a better spray pattern than the stock style injectors and I noticed no difference in the idle quality. Kinda was my round about way of saying that even if you put the same size but better style injectors in your truck, you will likely see the same thing. 

 

I'm sure you're great to have conversations with in person if that's how you act through a keyboard. One little things sets you off and now I guess my dick is all up in your face.
