i need a little help figuring out what my injector settings should be... there 36# flex fuel injectors from a 09+ silverado. on a nnbs silverado the fuel system is returnless. which cuases the ifr table to be variable. now my 99 has a return system. i found a few spreadsheets that let you type in what all your settings are and what not, but even those are variable. do i just use those or is there just one number i need?
alright, im still having trouble converting the gen 4 to gen 3 injectors, the tables dont ecatly match up from a 2010 silverado to my 02 pcm. im just lost in the math.... we tried 41 like my spreadsheet showed but it was way lean. but at 34 ifr it was close. so im just a little confused. should the ifr vs voltage vs map be changed? if so where can i find those values if the 2010 tune doesnt have the same tables.
Go to the tune repository and search flex fuel and a few come up which might help you with your tuning.
