Big n/a cam (don't know the exact specs)
Using 2 bar OS
IFR divided by 2 and stoich multiplied 2 by to work around PCM injector limit.
As soon as the wastegate opens there are lean spikes in the narrowbands in the log, the wideband agrees.
Any ideas on what could be causing this?

Am I missing something? The wideband reading just says 11.29 for me straight across the whole log
You need to change the AFR IVT terms also, cut them in half. Probably not your problem, just noticed it thuogh.

The customer hadn't pulled the signal and ground out to log the WB with my hpt interface, ignore the wb reading in the log posted. I'll put another log up with it working when he pulls the wires out.
Yeah, post a log with that + state where it happens, by frame #, so it narrows it down. I guess if it's a short log it will be obvious, but the more info the betterOriginally Posted by VodeAn
Not sure I can help, but the better you put the info out there the better chance you get a useful response

I am the vehicle owner. If there are any set up specific questions that may be needing answered I may be able to help.
Also we may be wondering if we could be seeing a magnetic field interference between the coils and injectors at higher RPM range. The coils were relocated where all 4 coils were stuck close together and mounted directly on top of 2 injectors on each bank.
Mechanical changes:
Found and fixed a fuel leak on the fuel rail
Moved coils away from injectors
The injectors were all on one circuit, now each bank has its own fuse
Cleaned the injectors, one was visibly dirty
Fixed 2 bad plug wires
Issues are gone.
