2 step with stalled auto
I have a Yank 3200 on my 08 base model. This is my first auto car so I'm still learning with the auto. I've searched on google and on here and I only found one thread about 2step with autos on here and it didn't have a single reply.
I have a LNC-2000 from the last car I had. I never used the 2step just the timing retard for nitrous on my last car. So how would 2step work with the auto? Would I only be able to bring it up to my max RPM I can foot brake the stall to? I talked to one person who has a auto CTSV and they told me with the stock torque converter they can bring the 2step up to 4,000 RPM with no problems. I want to use the 2step that way i can have more consistent launches without having to look down and feather the throttle just go WOT once staged and watch the lights.

Best launch RPM for me with a stock TC was around 1,100-1,300.

That's what I was thinking when I was told stock and 4k. My car really wants to creep forward around 2200ish on the street.

I had a lnc2000 for a few months and it "worked" kinda. As far as consistency it was great. But for some odd reason I wasn't able to go as high as I'd like it to go. Say I had it set to 3200. In neutral it would get to 3200 and stay there but for whatever reason in drive it would stall up to the 3200 and then would cut down to about 2500. As far as fastest passes goes it wasn't there but for consistency it was great. I don't recall trying to go lower than the 2500 it was defaulting to though.

Yep works with an auto, you would only use the low rpm limit tho and tie it to a line lock momentary switch / can be with or without the line-lock, point is the 2-step is activated when you hold down the button and not when you let go! Easy !

So you do not change the converter stall with a 2-step, you are just limiting rpm by removing spark from coil packs while you have the "button held down" so you can just mash the vertical pedal on the right and have consistent launches!

2-step wiring
No splicing is needed. The Lingenfelter 2-step plugs into the main coil pack harness connectors for each bank with plug-and-play mating connectors.
On the Gen V engines (LT1/LT4/L86/L83) they no longer have the per bank connections so then our LNC-2014 connects to each coil with similar male-female mating connectors so it too is plug and play for the coil/signal connections.
You still have to wire in the activation part though (to a switch or other device depending on how you want to activate the 2-step).

This is the signal wire I was asking about.. The activation for 2step. I know most manual guys splice into clutch switch but where is a good splice for brake signal? And doesn't the lnc2000 wire for 2step ground activated?
