I am wanting to run a 150 shot on my 6.0 ls6 just wondering what timing curve should i use in the msd ignition module. (right now i have curve 6 in it)

I'd try MSD's web site or tech line...Maybe even the N2O manufacturer

you want the msd 6010 box so you can program your own timing curve and nitrous retard,,, all the msd pills have 36* timing wot,, that is way too much for a normal lsx engine,,, put nitrous on to of that an you will be melting parts

Yep. You can't run those pills with the LS1 motor(and get it to run right/make power)....Let alone add nitrous to the mix. I don't know what the MSD/Edelbrock engineers were smoking when they came up with those timing curves...But I want some.


Get the 6010 box and program your own curve. Usually around 29-30* total timing with stock heads. Then pull 2* per 50hp sprayed via the Nitrous Retard function. It's simple to setup.

while i agree you shouldnt spray with that much timing, how do we know that it hasnt been researched to run more timing on a carbed ls1.

efi, fuel is sprayed in, only air is sucked into the motor.
on a carb, the fuel and air is drawn in.
this could very well make a difference in the timing setup.
on motor, i have played with curves, and different timing, and the car runs the same et/mph from 28-36 degrees.
ON MOTOR.
im going to use the retard for the nitrous to be safe.

The stock curve in the 6010 would spike the timing from 29 to 36 somewhere around 4800 rpm. It caused the car to break up. Then I dropped it to 29 across the board and it ran mint.

36 is too much from what I've seen.
