I am going to use COS 5 pretty soon for a dry nitrous car - can anyone give me any help as far as fueling? Is there a way to calculate how much fuel to add in the VE multiplier for a given amount of nitrous? Seems to be a shot in the dark, but I'm not wanting to shoot in the dark LOL!

Also note this extra bit of information:
from this thread: showthread.php?16310-question-on-custom-os-0202005There's a bit of a trick with the NOS timing retard, it will only function when table B5956 has a multiplier value of 1.00, typically at idle / part throttle this can be calibrated to 0.0 from factory. I had completely forgotten about that, it was 6 years ago we did that OS

It's unlikely that there will be any updates/changes to the LS1 calibrations. They have been available for many, many years now and customers have created some pretty radical vehicles. We don't consider that anything needs to be changed for customers to achieve their tuning objective.

It worked on my LS1 for many years. Wished they had one for my L99.

Why do you want one Bill? Valet mode? IMHO I dont really see the point of a COS for the newer ECMs with a VVE table. The only reason I can think of for a COS is the dual fuel/N2O COSs EFILive has for the E38/E67s OR to extend the spark table past the 1.2 g/cyl for LS1 or 1.36 g/cyl for E67/E38s to better control it while under boost. The newer OSs dont even need that, you can scale the spark axis to whatever you like.

Whats the best way to populate the TPS map at the hard to reach, low TP high RPM area?
