LS1Edit & Engine Displacement I have started to go through my setup with LS1Edit and I have a question about cylinder displacement. First let me describe my setup:
- Car has MMS programming.
- 3.91" Bore with a 4.00" stroke
- Stock C5 Injectors ( 26 lbs/hr )
In LS1Edit, taking the cylinder displacement a multipling it eight, it yeilds a total volume of 375 CI. WTF???? With the bore and stroke I have, I should have a displacement of 385 CI. Why in the world would Mike program the displacement to 375? The only thing I can think of is to accomidate the smaller injectors. Any one else have an idea?
I am currently installing SVO 30# injectors, should I also change the displacement correctly also?
TIA.

Re: LS1Edit & Engine Displacement There are a couple reasons
His math sucks. <img border="0" title="" alt="[Razz]" src="gr_tounge.gif" />
or
Fueling. Alot of tuners, despite the engine size just leave it as 346 and play with other charts instead, so it is not that important. It is a great quick and dirty way to adjust fueling though.

Would it be alright to set the displacement to the 'correct' size and the inejectors for 30# SVOs and then tune the MAF and PE vs Attack tables to achieve the desired A/F ratio?
