So I Swapped my 07 VQ revup to my 03 Z which isnt a rev up.

Using an 03 ECM and the 03 Wiring harness.
Car runs but there is a bunch of codes that are on!
The is sluggish when it hits about 4k rpm
I was also wondering would it be better if i just ran a Stand alone instead of rewiring the whole thing. Cam angle sensors isnt plugged in.. Advise guys i need them!!!

 

you need the rev up ECU and most likely the harness as well. VVT on your original '03 VQ only works on intake valves. VVT on the rev up motor works on both intake and exhaust valves.

 

I know I need the 07 ecu And harness but I was wondering if thers another solution. Cuz the one u just said is a pain in the ***.

 

well good luck with it kid. this is what happens when you don't things right the first time.

 

Was looking into this with my car and my 6mt swap. You'll definately no way around it need a rev up ecu, rev up engine harness, AND new wideband a/f sensors or else you'll have a code since 03s use narrowband a/f sensors.

 

ok cool ill redo the whole wiring... thanks for the advice...
