i have an apexi vafc (not vafc2).. i hooked it up exactly like the diagram and now when ever the controller is plugged in, for the first 2 minutes the engine throws no CEL and when you hit the accelerator it bogs down.. after 2 minutes the CEL turns on and rpms go high (2k).... i keep on reading online about some people leaving the VTM disconnected... idk if i should do this.. please help guys? this is the diagram i used..Here page 11 (also.. i have 2 map sensors... one of them doesn't do anything wether u plug it or not..)

i have a b16a2 engine thats been converted to obd1 and is connected to a p28 ecu... maybe the conversion is doing something..

 

i fixed it.... i disconnected the VTM and now the motor runs good at idle and no CEL... the only problem is that when you hit the gas hard.. the engine bogs down.. when you hit it gently then it doesn't... same thing as my other thread... if anyone wants to come fix it ill give you a working p06 ecu (the only thing of value that i currently have and some may want) and if you wait till the 15th of august ill pay you what you earned...
