When checking through all sensors are connect and no errors, everything is good. Car is a Rotary turbo drag racing only. For fuel I'm running 4x brand new 2250cc inj. Mechanical pump "no electric", I did wire the fuel pump rely to a led light, and it shows the light turn on as a pump would, and shuts off normal when ecu starts afterm a few seconds. Then when cranking light is always on. I noticed the injector ms stay at 9.33 during crank. Figured I would ask first as this is a new drag setup and first time running mechanical pump. Any experience with this before? Is it normal to read ms on LT10s with car off?

Also abnormal ms reading for my injectors. When I start the car, and it is just pouring fuel down, and fouling out spark plugs. I have my Idle and 1000-2000RPM screens set down to 1.5-1.8ms for the injectors but my readings for the injectors with the car running at idle show 3.5ms way to rich for the car to run correctly. I have went through all screens that would add fuel such as Air, Water, all of my AUX inputs and 0.00 out all additional fuel. Still no change. Is there something I'm missing when running high impedance injectors 8.Ohm and no electronic fuel pump. This is a drag car setup so I will not need driviblity corrections, I just want to be able to input my map screens the correct ms for injectors, and control the fuel correctly. Any direction would be much appreciated.

Thank you,
Mike

Check your %Stage. The primary injector time is multiplied by 1.that number to get the primary pulse width until the secondaries begin to fire, then primary pulse is reduced.
