Custom o.s#5

[articSS]

i was wondering if there would ever be an option to add another table to control a second stage in COS5. Im sure im not the only one who would like to see this happen.:grin:

No, LS1 custom OS's will not likely be enhanced from what they are.

You could do it by intercepting the IAT sensor with the second stage. Second stage would open the IAT circuit giving you an IAT of -39degC. Then timing modifications could be done in B5911 & B5943, & fuelling in A0014. It would not give a lot of adjustability but some reasonable control. If you were only running the first stage for a small area of the rev range you could reverse this & run the iat intercept for the first stage, & the nitrous pin & tables for the second.
