Built engine high RPM hesitatiom

[STE92]

Just recently completed breaking in my engine and started the tuning process. Having a weird issue at high rpm, bank 1 AFR goes lean 20, car hesitates for a second and continues. I was thinking hpfp going bad, fuel pressure deeps for a second and recovers doesn't affect bank 2. I get no codes, any help will highly be appreciated? I'm running on fumes

Well checked plugs...replaces map....new hpfp. Same issue.

Im just throwing out the ideas... Maybe swap knock sensors, see if anything is touching them, if they are torqued correctly?? I have no clue, just figure its easy to do... Good luck! I just know I'd be losing my mind

Man thats bad. Its an awesome build, but it could be literally everything. V8bait knows his stuff. So no doubt the tune is good. As there are no codes thrown I would just tear the peripherals down and triple check everything.

 

[STE92]

At this point is not much it can be... harness check out...also dme. Coils...injectors... spark plugs, even replaced some sensor...no change... things hasn't change is tune. Hopefully hear from him

 

[STE92]

Brother ty!!!! .... I checked my knock sensor and realized one was in the wrong spot. Swap it...just did a run and xlean!!!!!

 

[Slowagon54]

Hell yea! On a build motor it can be everything. There is so much you have to take care of. Glad to hear its solved

 

[STE92]

Man something so simple. Didnt even know there was a second spot the sensor fit... I'm glad is done and we can turn this thing up....ty so much everybody help and time

On the subject of weird things that can cause a problem...

The main power cable from the alternator under the IM near the HPFP.... if that gets left out of its routing path, I am convinced the EMI from it can affect the hpfp solenoid operation.

datazap.me

can yall help me out on my issue too lol
getting a "superknock cyl 6" code, but seems to be leaning out up top.
20psi im good but anything above 21psi i get this lean out/superknock.

things ive done or changed:
plugs are new gapped at 0.018, new NTK O2's, new Cam shaft position sensors, new crankshaft position sensor, BMP Aluminum manifold Port injection with 750cc injectors, PR coils, cleaned out vanos filters, new index 12s (coded correctly), upgraded from MSD80 to MSD81, new knock sensors, checked compression (all 6 cly are good).

things i havent done yet:
cleaned intake ports, cleaned vanos solenoids, and checked leaked down test.

plz let me know what yall think and give me more ideas i can do to fix this missfire/supcerknock/lean up top.
