New engine--need startup tune for break in..

[frodo84]

I am building a 383 to replace my existing 346, how can I derive a reasonable tune to start up and break in the new motor? Can I extrpulate a new tune, based on the increased displacement, cam, etc.? TIA for any advice...

Best bet would be to set the engine displacement parameter (785 IIRC), then follow the AutoVE tutorial.

Just make sure that if you have different injectors, that the IFR table is correct. Car should start up fine and be stable enough to start tuning. Like TA said.....read that tutorial!

I'm guessing B0104, mine is 708.2 for a 5.7L

{B0104} and for a 383 it's 785cc's.
