96 OBD2 prelude S --> 94 OBD1 prelude vtec
I did an engine swap in my 96 OBD2 lude w/ 2.2 SOHC, and put in a 94 closed deck JDM H22A OBD1 engine. I reverted my car back to obd1 with the adapter harness, and am running a spoon p13 ecu. I'm wondering about this resister pack everyone talks about. Should I have used this?? I thought it was for going obd2 from obd1, but I have read a few posts that say it's the other way???
My car has been running REALLLLL rich lately and maybe that was the reason..
Anyone got any ideas?!???

I believe the 94 ludes use them. If you measure the resistance of the injectors you can tell if they are high or low impedance. Low resistance needs resistors.

If I'm not mistaken, the low impedance injectors are the saturated ones correct?? So I need to ditch the resistor pack if I am now using the peak/hold type injectors??? Can someone clear this up for me I dunno??

LOW impedance injectors are also known as Peak and Hold injectors. If you are running peak and hold (Low impedance) injectors, you must use the resistor pack or you will likely fry the injector drivers in the ECU.
