I did a swap a jdm h22a from a 93 Lude and the ECU they gave me with the swap was a P13. I just looked on hondata's website and they don't have a P13 ECU for the motor I have, they have a whole lot of others but not the P13. So I'm wondering if this is the right ECU and is the P13 an obd1 or obd2?? Cause I read in a post here that obd1 ECU for the h22 only read 1 O2 sensor, however my check engine light came on after the swap and the other day I had it scanned to see what the CEL was on for and it was code 41, which is an O2 sensor and I alredy have 1 O2 sensor hooked up. So I'm a little confused. First of all why doesn't hondata show a P13 ECU and why is the CEL on if I already have the 1 O2 sensor connected?
