Default Precision 1000cc injectors No Start

I'm on crome, yes...I don't want to hear about better fuel management.

I had the map scaled for 450cc injectors with 10watt 10ohm resistors soldered in line and I've ran that setup for the past two years.

I just picked up some precision 1000cc injectors low impedance as well (2.4ohms the 450s measured at 2.6ohms) and I can not get the car to start. Figured maybe I flooded the cylinders so I pull the plugs multiple times and I can't smell any fuel no matter what changes I do to the fuel multiplier or the injector offset. I selected the correct injector and played with the offset, tried 0, 30, 48 and 60. Nothing, no start.

Yesterday I had the car running on the 450s for about 30 minutes.

I can hear the fuel pump every time I key on.

Any ideas to help out?

* figured it out...offset needs to be in the 110s as well as precision 1000cc injectors chosen on the injector selection table for precision 1000s to idle.

hello brother. I know this is a old post and i apologize for flaming it. But I recently just got rc1000cc and I'm having the same issue even with stock honda obd1 resistor box installed.. I was hoping you got it figured out and can lead me in the right direction.. its a long shot but I hope this message reaches you.
