Neither of your zip files are working for me guys

 

IFR 41.6673
small pulse threshold 3.996945
injector flow correction = 1.0

thats from a radix tune on efi live repository

 

PM me your email and I will send you the excel file.

 

I am fully aware of what is involved, just finished tuning the 72lb injectors in my returnless fuel system.... fun. Anyway, I was trying to clarify what injectors he had because I have allot of injector settings, as in I also used to have the multecII 43lb injectors as well as the settings that go with them............

 

Actually I just looked and in 04 the multecII injectors should work just fine with the stock injectors settings. Just change the IFR.

 

Technically no that is not right. Yes I am aware of how many people are running them by just changing the IFR and they are a nice upgrade because they are plug and play and whatnot but the fact is once you throw a different injector in and still use all of the other stock injector settings besides the IFR then the tune will be off because the error you have in your fueling now gets "baked" into the VE table which isn't right.

Sometime take a stock tune file from a truck with the stock 24lb injectors and then the file from a 3/4 ton with the 8.1 and see how all of the offsets and everything are completely different and we are only talking about only 5-6 lb/hr difference between the two injectors.


Obviously not every single injector is going to flow exactly the same but however if they did and ALL of the correct injector data is changed when swapping injectors and I am talking about going from 24s up to 60s nothing else should need to be messed with in the tune if the data is correct.


I know their are alot of people running the MultecII 43lb injectors with just the IFR changed and their application runs fine like this but if their is an injector avalible to upgrade to that has all of the info on them that would be the better choice.

 

I am in no way trying to get in a pissing match or persuade anybody from using these injectors I am just simply stating the facts about correctly tuning injectors that's all.

For me personally I would rather spend the money and go through the hassle of changing out injector plugs on the wiring harness if needed to go with an injector that had all of the info on them and that goes the same for a customers car or truck I am tuning. I do like to have my tunes be as "spot on" and as close to perfect as possible which I dont view as being a bad thing at all when someone is paying me and expect a good tune.

 

does anyone have any new info on these injectors? I will be safe with the IFR #'s generated in the excel sheet floating around?
