I'm getting the hang of tuning this thing, P59, 2005 CTS-V, LS2 SNS stage3 cam, .020 over bore flat top valve relieved pistons, H beam rods, 60# Deka injectors, sheet metal intake with a 90mm LS2 throttle body. I got the LTFT's down to +2% but my idle is really rough and a tad lean, I tried adding fuel at idle but it just wont idle unless its lean, I'm going to attach a recent log and file if someone could point me in the direction I should go I would greatly appreciate it.
2005 Cts-V 366 LS2 forged rotating assembly stock stroke, LPE TRG-002, JE Flat Top 4.009 pistons, Tick SNS Stage 3 Cam, LS7 lifters, BTR 7.450 Hardened Pushrods, BTR Dual .660 springs, Harland Sharp 1.7 Rollers, Katech oil pump, C5-R chain, Mantic Single Clutch w/Tick remote bleeder, Hurst short throw, 8.8 Torsen 4:10's, 31 spline DSS, K&N intake, mid rise sheetmetal 90mm TB, 1 7/8 OBX Long Tubes no cats, AEM Wideband, ATI Balancer, 160* Tstat, lowered on BC Coilovers, HP Tuners Pro
Get your idle timing a little smoother and it will want to idle better. Aim for 20ish degrees of timing at idle. Your park/in drive timing settings are weird and the high/low octane has a big difference in number for timing around idle. Also lower the over/underspeed spark correction to 8-10 +/- instead of 20 degrees.
I can't view the log as I'm using older software but it may take some more playing with the idle rpm and base running airflow too.

If you don't post your tune and logs when you have questions you aren't helping yourself.
You can give this a try if you want but you will probably have to add more base running airflow.

You are in OL. Your WB reading never changes. You may need to Transform the channel again or check the wiring. Something is not right since the NB voltage is showing rich up until the 10 minute or so time stamp then moves around a bit but again the WB does not change. Check fuel in CL with the LTFT+STFT math histogram.Originally Posted by 366LS6v
.Are you running a 3BAR MAP?

Yeah I missed that. But I can't view his log either.

Use the Beta version and you can view the newer logs/ tunes without updating to ver 5.xxx
Cool. Thanks

yes OL, had STFT off dialing in the LTFT and my wideband in the Scanner wasn't recording any data, but was reading a lil lean at cruise 15's on my gauge. I'm probably going to run this SD. I'll post a log before the STFT's got turned off.
3 BAR MAP is correct as well as the data is correct for the Sensor I'm using.
these logs are using the BETA version

your wideband is still not recording on the log. how do you have it connected?
