What Cylinder Size do I use in LT-1 Edit
My car is still a factory LT-1 350, the stock program reads 44.041 cylinder size, but most peoples cylinder size reads 47.895 when they have sent them to me. I'm reading them in LT-1 Edit, what's going on here, could someone fill me in.
Thanks ...Rich |
47.875 multiplied by 8 cylinders equals 383 cubic inches. if you a 350ci LT1 ( stock displacement ) then 44.041 is correct.

BTW: this is one of the basic parameters I use to tune if there is a general lean or rich condition. It's OK to "lie" to the PCM. My current tune has a cylinder size of 60ci (for my 383).

My current tune has a cylinder size of 60ci (for my 383). Rich Krause U seem to be a man of knowledge. Why would you choose the cylinder size to tune for lean/rich as compared to your injectors or for that matter your MAF tables or even your injector offset vs. voltage? Just want ideas for myself.

From my experience the cylinder size doesn't make that big a difference in a MAF car - in a speed density vehicle it does though.
