I'm very new to all this, but I'm trying to understand what the car is doing and how to tune for it. I bought a 2002 WRX with the following mods:
-EJ22T block with ACL bearings, '05 STi rods, WRX heads; few other bits.
-FMIC (looks like a no-name, eBay type)
-COBB SF intake
-ACT 6 puck and flywheel
-Borla hush 3" cat back (I believe the entire exhaust is 3" catless, though)
-DW300 fuel pump
-Unknown injectors; I think they're stockers, but I'm unsure. I have some DW1300s ready to go in, but I need to get better at understanding tune, first.
-Colorado Springs, CO (elevation ~6500'), ~70ºF
The guy I bought it from put on some generic tune he found just to get it all running. From what I'm seeing, it's very close to stock in most ways and different in only a few areas (like the boost target map). I don't want to post it because I don't know where he got it; I'd hate to post some tuner's hard work for free on the internet. The MAF scaling table is identical to stock, which I believe it ought not be for an SF intake. COBB says you don't need to rescale the MAF for a 2002 with an SFI, but I found an MAF table for the SF intake on ROMRaider (link) but I think I need to do the MAF hack to get my MAF to read over 300 since the table I got goes to 488.86 at 4.96v.
I did my first log the other night with a WOT pull (3rd gear) from ~2200 to what was supposed to be redline, but the power cut out quite a bit at around 6000 RPMs. You'll see why from the log. I'm trying to wrap my head around what's going on, here, but I sure could use some direction. From what I understand, the ECU pulled timing because of knocking. Could this be caused by the MAF reading incorrectly? Too little fueling? Too much timing advance at that level?
