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

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?
Yes the nitrous timing retard should be intsant.
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.Quote:

I havent had the time to fool with cos5 yet so i dont know how its gonna work. Im in the process of getting my iats down from the 230* range :muahaha:Quote:

I have a 4.8/t56 turbo combo with cos5 and a msd 2 step. i connected the msd ground activation with the nitrous ground activation and ran it through the clutch switch. i set the nitrous activation to pull timing and add fuel and activate a few hundred rpm before the msd 2 step. it all works pretty well but its sensitive to the correct amount of fuel added to really have a good bang out the exhaust.
