Hey all, I recently “finished” my 240 +T, and ran into a couple of issues along the way which I solved and it progressively ran better and better. However, it will still set the 1-4-3 code and I can feel it pull timing at anywhere above 2,800 rpm. I’ve done a lot of troubleshooting and am running out of ideas. So far;
Verified good fuel and injectors, brand new FPR, 93 oct
Verified ignition and cam timing, tested very advanced and very retarded on both, no change
Verified good ignition coil, (maybe plugs) and gaps at 0.28
Brand new knock sensor torqued at 15ftlbs
Only thing i might think of on this list is the fuel pressure regulator may not be working properly, although testing that i think requires buying a fancy gauge that may not yield me any useful fix
Current specs are;
13c with 1bar wastegate
Redblockpowered ecu and ezk chips
Bosch 0280155759 red top 850t injectors
A cam with adjustable gear
Sucky loud open downpipe but definitely free flowing
I have heard that possibly the pcv can spew too much back into the intake and lower the octane causing pinging/knocking? Don’t really think thats causing it that bad but its one thing I haven't really figure out a way to verify. If anyone has any experiences to share or ideas to try i’m almost at my end. I’m sure it’s something stupid obvious that I’m missing but have zero clue as to what is causing it at this point.
