    Default 60 degrees commanded ignition timing

    For some reason the computer is commanding close to 60 degrees of timing even under full load . How my engine survived the 500 mile trip is beyond me with that kind of timing lol . Its a 2003 lq4 , with SD3 OS running N/A . I did a full reflash and it was still commanding close to 45 . I have no idea whats going on I have checked all the tables . I'm attaching my log files and tune . Any help would be appreciated .

    Also this setup is in a 2009 jeep wrangler , and I am running this tach emulator from novak adapters . I'm having a hard time getting it to work , I put in a pull up resistor as told by them guys . Changed the high/low tacho pulses to 3 as requested by them . Now they are telling me and I can't remember correctly what exactly they said but HP tuners has another setting which I couldn't find in efilive that says 'tach output' that needs to be changed to 'crank' . Is there anything like that . Once again thanks .

    I don't see anything in your .ctz file that would cause spark timing to go that high...

    try doing another full flash.

    I will try that , weird thing is the ecu wont start adding timing right away, it happens after about 10 -15 mins of steady cruising.

    How are you failing to speed density? Is there a maf hooked up at all?

    Still haven't resolved the issue , tried full reflash a few times. Tried the custom SD OS 3, 2 bar and 1 bar with same results .

    Also not related , I keep getting these codes . They only happen at a cold start after I put it in drive and idling . Once the codes are triggered the engine stalls and wont start again till I clear the codes . Has happened a bunch of times . Pissed a lot of people the one time it quit at a light during morning rush hour . Now I just kick it into neutral everytime I stop at a light and the engine is still cold . I did some searching and what I figured most people that have the problem are running FI setups and happens during boost . But my setup is N/A and it only happens at low airflow conditions.

    Two problems: MAP is out of bounds, MAP/MAF correlation is out of bounds.

    +1 what statesman said.

    Did P0106 just start showing up (or was it always there)...?

    Did P1514 just show up after tuning...? Check for this again after you fix P0106.
