6k rev cut, but commanding 7200

[taylork057]

Ive been having trouble with this one for two weeks now. The ECU will randomly cut fuel/ignition between 6200 and 6400. If it doesent, it will allow me to hit my target limiter. Boost cut is well above my boost pressure. I have been in contact with AEM and we are still working on it. Just seeing if anyone else here has ran into this problem before and if they resolved it.

Items Ive replaced-

Cam sensor and magnet
coils
plugs

Logs upon request.

Its a

DCR option b engine
Their "Race" port head
GT3582r
bc3 cams/springs
1000cc ids
Boost controller is wired into ems
no tip solenoid, wastegate and surge valve, all taken out.

so far on 19lbs its making 495 at 7200rpms(when it does work)

post up a .cal, it could be lots of things if you can post the cal file up and a log of a dyno pull (or street pull) when it happens
