Question on 42 lb/hr Marine Injector Values
For a N/A 6.0L, would it be safe to copy over all the injector values from a 6.0L radix tune? I'm thinking yes since the radix ships with the same injectors and they build no boost at idle. As long as the years and OS match, right? I'm sick of dicking around with the settings and trying to figure it out myself.

This is a very important piece of the puzzle IMO for returnless fuel systems... I know that I have a FP drop at WOT (verified with a mech gauge), causing my IFR number to be inaccurate, thus inflating the VE values, thus causing it to calculate the wrong Airmass, at least IMO.. I plan to do some testing with a electronic FP sensor and the aid of the attached spreadsheet which compensates for ACTUAL fuel pressure, instead of 58psi across the board.. Also redhardsupra did a really good write up on the affects of actual fuel pressure in regards to IFR and VE values... as seen here

The main thing is to make sure all of the injector tables are tuned other than just the IFR their is voltage offsets, min. pulsewidths, and so on. If injectors are changed on any vehicle and somebody just goes in and just sets the IFR table and calls it good then you are pretty much "raping" the tune because then the fueling error just ends up getting "baked" into the VE and then the airflow calculations are wrong. If injectors are tuned in right then their should only maybe be a very slight adjustment made to the VE table at the most.

The 42lb marine injectors are a very nice choice for an upgrade especially being plug and play for the trucks but I dont like the fact that their isn't much in the way of info out there on those suckers unfortunately.

Me personally no I am not running the Multec II 43lbers

Are these for your truck? There is a spreadsheet around to calculate the values to use for IFR at least.

Same idea as the sheet Corey posted. Sorry I didn't notice he posted one till later.
