Who's runnig 2 step on their LT8s?
 

I know there's posts about wiring and setup, but I've been looking for videos on youtube and I can't find any. What I'm looking for is how how the 2 step actually behaves. I know they aren't spark cut (I could be wrong). So what I'm asking here is does anyone have a video of their LT8s running the 2 step. If possible could you send me the link to the video. I'm not looking fir wiring diagrams, I got that, and I'm not asking for your settings, I'm just look for a video of how the LT8s acts with the 2 step option. Any info is greatly appreciated.

Thanks man, that actually helps me out alot, it acts a lot better than what I was thinking, looks like I'm wiring mine up.

Do you have any screenshots of your tables for the 2 step?

Thats with no timing and only slight fuel under cut too.

how do you have your rev cut and rev lim set? because dont you have to have those set in order to run the 2 step, and also dies it build boost?

2-Step settings:
(13) Inp RPMlim 6500 (14) Inp AIRadd 0.00 (15) Inp Enrich 0.19 (16) Inp Timing +00

Gives me an easy 5-8psi... haven't held it more than 2-3 secs.

Regular rev limit settings:
(09) Opt REVlim 8500 (10) Opt REVcut 8620

Got ya, thanks man, idk how that will do on my car, but i got a base line now. I have a s4 T2 so my rpm setting will definitely be lower.

Hmm something not right, here are my settings. Idk if im too rich or not enough timing pulled, or what.

Rpm revlim 4000 (tach bounces at 4500)
Timining 0*
Enrich 4ms
Airadd 0

Also I think my presilencer is blowing out

Remember it's adding fuel based on that load point in your map. Around 4k might be rich already (spooling region) and then to add 4ms is too rich. Try my settings including RPM point.

I retarded timing to -20 and it seems about spot on. But now I need to get it out on the road and test it, if I have the timing set to 0 it does about 3 pops of fire and then sounds like its just sputtering, when I retarded the timing to -20 and keep my enrich at 4ms it got a nice rev bounce, if that makes any sense.

I made another thread about 2 step tuning and have a video on there.
