I have search EfiLive, read Swingtans sticky's and used his settings, read RingRam's tuning doc, and every tutorial I could find for mafless tuning. I am still missing the ohhhhhh yeaaa! factor. I've been struggling with how the idle, air, and fuel tables interact. So there, I've got enough knowledge to be very careful.
My ride is a 55 Chevy with manual 6spd, LS3, Texas Speed cam(229/236 629/615 lift, hi-ram intake, stock injectors, 2" headers, and 3" exhaust.
I try to start 5 to 6 times also feathering the throttle to finally start. It starts to start then dies. It helps if I try very little throttle.
I know I will get some crap because of the many changes Ive made to each flash. Ive only done 8 flashes so I'm read to (an know I should) makes small changes. But one would have to know what they are looking at to make those changes. I just don't get what params to change based on the scan readings. Side note...when viewing a log I use to be able see the changes by moving a mouse across the dashboard graph but the vertical line does not display anymore?
Hopefully someone can decipher what I've. Once started the engine runs great except when I stop at a light then the idle stays high for a long time and sometimes will not come down at all.. I do have 2 wideband o2's installed but not connected to the V2 (can't figure it out). At idle they both read 11.7, driving they are around 14.5. but hard to monitor while driving.
I included a cold start log, the tune I flashed, a log after the cold start n flash, and an excel file showing the 8 tunes flashed and the setting changes.
Thanks
