First...
No leaks from intake or exhaust, BLT to 30psi shows no leaks, all gaskets are in place and bolts are tight. Mechanical and base timing are verified correct. Fuel pressure is verified correct (43 hose off, 37 hose on) Compression is 195 across the board. Wiring is good, no shorts, no gremlins. Stock O2 is good, wideband is calibrated and working correctly.
Mods are in profile but the basics are: Built 2L, 9.3:1 (calculated), mild head port, stock size valves, composite HG. RC 1200cc injectors, Fuel Lab AFPR, Jay Racing PT341 pump, fresh stock fuel filter, E85. FP race manifold, FP intake, O2 eliminator DP w/3" cat, 3" exhaust. BC 272's, FP DSM GreenXl w/84mm cover at 24psi. IInnovate LC2, ECMLink V3.
Basically, I idle at 900 at 15.2-15.6:1 AFR and part throttle cruise nets similar AFR's, I'm fairly satisfied with that aspect of the tune. Acceleration at any throttle position (low or no boost) nets 10.4-11.1 afr's regardless of changes made to the SD map. Full throttle acceleration nets 11.5-12.5 until 7-8psi then climbs leaner until I hit 17:1 or leaner at full boost, again, this is regardless of changes made to the SD map.
Attached is a log. It's a long one (12 or so minutes) that shows idle, PT cruise, acceleration and WOT. I apologize for the length of the log but I wanted to make sure I captured all of the areas of concern.
Thank you guys in advance for any input you can offer. I've been analyzing and adjusting so many things trying to get this right and I'm simply not seeing things right any more... I'm sure I'm missing something but I can't for the life of me figure out what it is. Thanks again guys, I appreciate any info you can provide.
