Were there any differences in the programming out-of-the-box from GM between the LT1 and WS6 equipped cars? Would an LT1 benefit from having WS6 programming flashed? I can only assume there would be a difference in air ratios with the ram air and all, but would there be anything else?

 

I seriously doubt that there is a difference between the programming. IMO, it'd be more worth your time getting something from PCMforLess.

 

There is no differance, its the same car

 

yes there is... THE MAF tables are different for the Ws6

 

Thats correct...Ive seen this disscused on the lt1edit list several times.

 

Correct... to account for the different intake track losses experienced from the 2 very different intakes.

 

I stand corrected

 

Though, I am still trying to figure out about a pre-98 WS6 that is not an LT1. <shrug> The question threw me.

 

Being that I own a WS6 and have been using LT1 edit for 3 yrs, let me shed some light:

There is only 1 difference between the standard LT1 tune and the WS6. As someone stated above, the MAF table is different. It is actually curved LOWER in the WS6, I am not exactly sure why this was done, I'd have to work through the logic of it vis a vis how the PCM sees the MAF output. However, if you put the stock LT1 MAF curve in a WS6 car would probably run rich. Timing and everything else is exactly the same.
