Re: Spark Plugs with Two-Step
As soon as 4 bulbs are lit I get on it. 2-3 seconds I guess. It's probably my tune still needs help in that two step area then. Yes Ed it always shows lean on two step so I try to use converter flash to tune the two step. It is the riches part of the run, when the converter hits.

Re: Spark Plugs with Two-Step
Bobby, on Patterson's dyno we were able to load mine at 3000, I set it to 12.5-1, richest part of my runs as well. Looks like about 15-1 A/F sitting on the 2 step.

Re: Spark Plugs with Two-Step
Bobby this what I have been using NGK UR45. Mine are grey to white. On the 2 step same as you. You can run lean around the pits and return road cause you have very little load on the motor. With out fear of burning a piston. Somebody correct me if I am wrong still learning.

Re: Spark Plugs with Two-Step
With the EFI systems, you just type in any RPM you want and it takes care of the rest. I'm not sure who sells chips that go down to 3000. Don't have anything that low in the super stocker that's for sure!

Re: Spark Plugs with Two-Step
MSD makes an adjustable module which goes down below 2000 - plugs in like chip - I have mine set at 2800 for launch.
