SO here is what i discovered today. Previous owner installed the sr20det before i bought it. No idea who did original wiring. I have been running my Innovate lc-1 w/b to the sr ecu using the narrowband simulator. The car has ran ok for months on this but never felt good. Hard to explain the feeling, just something was off. So i went to testing the wiring near the ecu to find out the o2 sensor wire was grounded to the chassis somewhere. I then cut the wire( a few inches from connector of course) and spliced it directly into the narrow band simulator. Let me tell you the difference. Took it down an open street, first gear shreds tires, second gear rips them loose as soon as boost hits 14 psi, then holds between 15-16psi to redline. WIth this tune and e85 i really can tell a huge difference.
Just wanted to share this story.
TLDR : Check your grounds if you didnt install the harness. P/O jacked them up.
