Default Problem at Vtec

This is for a friend of mine.

Stock b16a SiR II
Garett/AiResearch T3 .42/.48 50 trim Turbo
Rank1Racing Short Tubular Manifold
TiAL 38mm WG, 7psi spring, dump into downpipe
2.5" Custom Downpipe
2.5" Custom Charge Piping
JohnnyRaceCar FMIC
1g DSM BOV
1g DSM 450cc Injectors
Walbro 255lph Pump

For tuning, the first setup was a P06 ECU with Uberdata. Second setup was JDM P30 ECU w/ AFC2 wired normally.

This was his very first dyno w/ uberdata:

This was his last dyno w/ uberdata:

This was his dyno w/ V-AFC:


The line goes haywire at VTEC.

He tried 2 different ECUs, so that isnt it.

Whats the problem?

Looks like the VTEC fuel maps are fucked.

that looks like its gonna run like ***, is it misfiring or running rough? Are the plugs ok, could be the boost blowing the spark out. Then again there are so many things it could be

appears to be uberdata rookie disease. its cured easily with practice and continued education.

I agree it's something with the tune, be it ignition or fuel.
