Default injector swap on tuned motor..

sup guys..well i had my crx with ls vtec tuned wit crome last month..the car had obd0 injectors and no resistor box attached and had my harness converted to obd1..i made 196hp/132tq incase u guys were wonderin..i recently swapped the injectors plus clips to obd1 and my car smoked a bit til warm..only started it twice n the second time didnt seem as bad..maybe due to new exhaust..not sure...but is there gonna be any issues with high/low impedence or my injector duty cycle??this is just a thought that ran thru my mind..thnx..

If they were obd0 civic/integra injectors, then they should have had a resistor box in place (these are low resistance injectors)

Then... if you installed obd1 civic/integra injectors AND took out the resistor box you shouldn't have any problems.

Either way, your ECU should see 12-13 ohms resistance from the injectors...

As long as the injectors flow like they should and the same cc then the a/f should stay the same.
