Hi all, I installed and LSA on my 2015 Chevy SS and I have built a working tune that it seems to run decent with, but I have been deliberately keeping out of the pedal to get some logs and see where I need to go from here. The system is basic with:
- LS3 stock with stock exhaust, etc
- DW injectors 65lb/hr
- new S/C with ZL1 lid and stock pulleys
- ZL1 heat exchanger with bosch pump
- Still working on building the Air intake but have the stock maf with a filter on it.
I chose a minimalist approach to get it running to minimize variables but I spent a lot of time on the high octane timing table and looking at other database tunes to get something I think will be safe to start off with.
I'm using the 3 bar MAP on the S/C lid, but haven't done the breakout for the temp sensor yet (will do this week on holiday). I runs and idles nicely on this tune and at light throttle acceleration seems to do okay. I haven't taken it over 3000 rpm yet and very slight/part throttle to get some data.
I have an LC1 wideband I wll install this week as well so right now just using feedback from stock O2s as I gradually
So my questions:
1. When should I have it set to go into power enrichment mode?
2. Should I be tuning VVE on this car? Do I need to? I have an LS7 maf card that will be going in once I build my intake.
3. Whats the best way to test that I'm ready to get into the throttle? Having a wideband and safe timing are my present plan.
So my overall intent is to make it drive like stock off throttle, which it feels pretty much like that right now, then run safe under boost. I have no specific power goals, just want to maximize what I can obtain from the setup above with a balance tune (risk vs. safety) while retaining as much stealth/stock characteristic as possible.
Thanks in advance
