Hey guys I may as well get the most bang for Santa's buck and post here!

I got my truck running, 383 Vortec w/ old school Edelbrock MPFI and an EBL Flash II modified ECM. It fired right up.

2 odd codes, I am getting a 15. Odd thing is that I used the same sensor and wiring that I had pre-engine swap. I do not yet have any coolant in it because I was trouble shooting a little before filling it with antifreeze. The Dynamic guys blamed the plug or sensor.

Next is a 23, IAT but I don't believe that I have an IAT. The guys at Dynamic said to just flash it out because there is no sensor but it is a little weird.


Anyone in Mid TN familiar with EBL Flash and want to help tune? I have lots of beer :waytogo:
