Replaced the SVO 39 lb Blue Giants with FIC custom injectors Ok, here is the latest and greatest. I got a set of custom flow matched injectors from Fuel Injection Connection fic.com. I spoke to Jon, the owner, and we went over what I really wanted and what my engine really needed. I wanted injectors that flow 39 lb hr @ 58 psi but they needed the EV6 connectors. He sent me a set of Bosch III rated at 34 lb hr @ 3 bar ( 353 cc), they worked out to about 39@58psi. Dropped them in, made sure all settings in the injectors tables were set to stock LS1 settings, plugged in the new IFR numbers and went out tuning.
Very easy VE tune and then touched up the MAF and done. AFR error at idle, cruising 0-3 and WOT is 0-1, an occasional 2% off, damn nice. Great customer service and super communication from FIC. 78-80 % duty cycle at WOT, spot on.
So, in a nut shell, don't over do it on the injectors and make yourself more work.
Attached is my tune, log and cfg. There is a couple of DFCO bumps but no biggie.
