  1. crankshaft sensor came from Hummer H2 LQ4 engine
  2. thank you for the answer. I'm suspecting bad crank sensor, I removed all spark plugs today, disabled fuel and ignition and cranked engine for a while. I still don't have any kind of reading in Trigger Scope. Only thing I have is jumping rpm's reading, 800-0-800 and so on. I removed crankshaft sensor and tested it with multimeter, it pulls up to positive voltage when I putting wrench close to it, but when I'm taking wrench away from it, it stays pulled up. Is that symptom of bad sensor? Sensor is wired to Storm's ground out green wire, and +12 ignition voltage from relay. Maybe it needs +8 volts?
  3. 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 Thanks
  4. here's screens of ignition and fuel. for the first time we had to start engine with MAP disconnected, because we are using mercedes sensor, it needs calibration yet. we are at sea level and it shows 160kpa, instead of 101. but i was not able to calibrate MAP with engine off, does it requiers engine running for calibration?
  5. I'm currently at work now, I will post pictures of ignition table and master fuel map this evening, any advice would be welcome. I just need safe setting for engine break in period, until car reaches tuner.
  6. I have not changed any igniton angles, currently it has 45 btdc as default. should I change it?
  7. well, engine was started for the first time, but we don't had coolant system connected, so we shut if off immediately. now I wonder, what settings I need, to be on safe side, until engine break in period?
  8. Sorry, but I can't clearly figure it what will be connection with firing order of 1-8-7-2-6-5-4-3?
  9. I'm done with wiring today, only injectors has to be connected, and I also want to try fire it up for the first time tomorrow. which mode has to be selected in pclink software? sequental?
  10. What about wiring? I mean which injectors to pair for sequental mode? I assume, if firing order is 1-8-7-2-6-5-4-3, then ijectors are wired same way: inj 1-8 to channel1 and so on
  11. for injection, group fire staged, right?
  12. Yeap, I have just found it, Atom cannot control stepper motors. I'm gonna wire BMW 3 wire one instead. One more question: can I use MAP sensor from some other car? or it has to be aftermarket?
