    first start tune idle issue

    Hey guys . Im hoping we can get a little help here .
    This is my first SD tune . We have played with small changes previously -bought books and SD tuning isnt really covered in any of them . So we are out in the deep water now .
    first start tune - car runs real rich and will not idle .Now will just crank . Im sure we are missing something? Any suggestions to point us in the right direction ?

    Do you have a dead head or return fuel system? I am asking since your injector data does not look correct. Since you are running on the VE table only, maybe you should look at a stock VE table and copy that for the first 105kpa and then smooth out from there. Your ve table is not good. Set your Power enrichment MAP enable to 85kpa. Delay to 0 rpm. Your spark table is like a max n/a table---boom. I would lower those 28/27/26 degree numbers to 12 for a start.

    If a return system, the ifr table should be the same across the board. Use the numbers for your injectors at the fuel pressure you are running. Yours is set up like a dead head system. The offset table should have the same numbers across as the 0 column. Check your min pulse numbers as well. These little things will give you fits.
