Hi everyone, I'm currently trying to fire up LS engine with G4 Storm, engine turns, but backfires. Here's engine setup:
LQ4 cast iron engine block with Wiseco domed forged pistons, LS3 CNC ported cylinder head. Compression ratio is somewhere 10.5:1, Link G4 Storm engine management, running 8 injectors and 8 ignition outputs, injection mode is set to Sequenital, and Ignition mode is set to Direct spark. injector number 1 is connected to link output 1, injector number 2 connected to 2, etc. Same for ignition. Firing order set to 1-8-7-2-6-5-4-3. Trigger setup is set to Chevy 5-10
Now about problems:
1. engine backfires.
I know it is definitely timing or crankshaft sensor issue, but I have rpm fluctuation due cranking, it goes to 670-700 rpm and falls to 0, then again. Is it normal due cranking?
2. I don't have any readings in Trigger scope.
3. I have few errors at Analog Volt and Analog temp, but MAP sensor works, and readings are fine, also all temperature sensors readings are fine
I also afraid about fuel quantity, so does anyone can advice safe start-up fuel map?
All I need is to fire it up, to car reach the tuner
