    Default COS 5 Nitrous retard for Anti-Lag

    Can the nitrous retard be used to help spool, by retard the timing while on a 2-step and t-brake? is there a max timing that can be pulled? min or max rpm engagement?

    I was thinking about this. Wondering if the 2step can be integrated to the N2O controls...

    Thanks

    IDK...

    the usual manner of COS5 usage is to modify fuel/timing when nitrous activates.

    I don't see why it couldn't. Hell you'll even be able to fine tune the fueling as well, which isn't possible with the MSD/Lingenfelter boxes. You could pull over 25 degrees, but you'd only need 10-14 on a typical build, imo. If you have the time why not give it a try?

    i dont have a 2 step yet, have heard the lingenfelter boxes have issues and msd doesnt do retard, which i wanted to make sure my idea would work before i drop 220 dollars on a msd unit.

    Well I bought the msd unit and tried to use this on cos3 using the iat table to retard timing, while this did work it looks like it takes about a half seond for the ecu to see the iat temp change causing a bog when i let off the 2 step due to only having 5 degrees of timing. Does COS5's timing features pull timing faster then this?

    perhaps it is the sensor itself which is slow not the ecu. I've heard of people wiring up a toggle switch that alters the iat signal instantly, can't recall if one of the circuits had a resistor inline.
