Hey, a bit of a back story here: I've been sitting on tuning this car for a really long time. My 2nd or 3rd mod was buying DSMLink but I haven't been able to really understand what to do with it to support my mods.
I am going to post my current mods here so you don't have to look at my profile: 3" VRS Exhaust, Meghan Racing 2.5-3.0" DP, TiAL 38mm with Recirc o2 housing, MHI Evo3 16G ported, DNP Tubular Manifold, HKS 264/272's, DejonTool Full Intercooler and Hardpipes, Aeromotive FPR, 650cc's, Rewired 255LPH, DSMLink, GM3.3Bar Sensor, GM MAF in Blow-thru setup, AFX Wideband.
I have done constant additions to the car and they all feel about the same as it did before I put the stuff on. I can't really feel a difference since the 16g went on. I am about to upgrade to a larger turbo but I want to get the full usage of this 16g to prove I will be able to tune the larger.
A while back I followed the GM Bar Sensor Tuning Guide and it took me on a path of leveling out my STFT and my LTFT based on my boost levels. I also did the math and whatnot for my full compensation (~32%) and injector dead time. The car runs fine, but not faster.
The other day I was attempting to tune with my new AFX wideband. My wideband showed me at 9.0 during WOT, which means it was below 9:1. So, I added fuel thinking that I was running too lean. It just started cutting out, so I reduced fuel over 20% on 2000k-8000k and it ran better, it was around like.. 10-11. That's where I left off with this log, it doesn't make sense to me why lowering my fuel made me richer in my A/F. Did I screw something up? I should be looking @ 280-300hp on pump fuel with these mods right?
Thanks for your help.
