    Default 522-205 injectors for Terminator Stealth throttle body.

    Long time reader, first time question. I've replaced the 80 lb/hr Terminator injectors with part Holley 522-205 205 lb/hr units. This is for a 1/4 mile bracket car. What changes do I need to make in the Fuel ICF to complete the swap? Reason for doing this is datalogs with the 80 lb/hr injectors show fuel flow at 320 lbs/hr before the 1/4 mile is over.

    I used the injector off times for the 171 lb/hr @ 30 psi settings from the following table: https://images.holley.com/205offtimes.png. Problem I'm having now is the engine won't rev much past 5300 RPM where it used to run to 7000 RPM. Fuel Flow in the datalogs shows over 430 lb/hr when the problem occurs. I'd like to make sure I made the correct injector software changes.

    The changes need to be made in the System ICF (Fuel System, Fuel Injector Information & Injector Off Time).

    My mistake. I meant System ICF, not Fuel ICF. Is it just the Rated Flow Per Injector (80 to 171 lb/hr), Rated Injector Pressure (43 to 30 psi), and the Injector Off Time like in the table I referenced?

    See post #2. Ensure those parameters are correct.

    I've attached the Global File and a datalog from a road test with the 205 lb/hr injectors. I think I have the injectors setup correctly. Hopefully someone has the time to look and confirm this for me. The problem I'm having is at WOT the fuel flow in the datalog is much greater than what's in the Base Fuel & Learn tables. I can't figure out where the extra enrichment is coming from. Look at the datalog at time interval 1.0 second. Thanks.

    Your Fuel System, Fuel Injector Information & Injector Off Time parameters are still not programmed correctly. In fact, they're all wrong.
