ECU Problem with my 1JZ
 

I recently purchased a Stage IIa ECU from 034 Motorsports, to control the amount of fuel going into the motor at low speeds. After trying to get it wired into the car we have found it does not control Spark. Does anyone have any ideas about piggybacking the Stock and IIa ECU's? Or is there another product you would recommend to control the fuel? Thank you for the help. :rolleyes2
