No secondary injectors on S-5 Turbo.
Did a S-5 turbo swap into my 82 FB. The car has ran great has about 800 miles on the swap. The motor is J spec and the ecu is a N-374 from Japan. Anyways no power what so ever when you step on it or hit boost. Starts, idles, run great, Basically it runs like it would minus the secondary injectors. Checked for 12 volts at the injectors with the key on, they both have power.. New fuel pump Walbro 255 in line when i did the swap. Haven't changed anything. was driving it when it happened, turned a corner and went to get on it a little and nothing.
Where to look next? Are the secondary injectors supposed to come on a 3500 rpm or so. Can i check for a burned out injector driver.
Thanks.

3500 under load.
Put a voltmeter on the correct wire for one of the secondary injectors. Go for a ride. When under load the voltage should drop from a steady 12 plus volts to way under 12vdc when you hit 3500rpm and above. If it does not.......bad driver in the ECU.
