after some research done, i ve decided im going with either PFC or AEM EMS.
the only thing i need to know is how do i identify weather my SR is OBD1 or OBD2.
my s14 is 97 USDM kouki. HOWEVER, i dont know what year is my engine came from since the ppl i got it from is an asshole.( i was told it came out from a 97 JDM kouki,but i saw the cluster in the front clip is black faced which means it is OBD1 zenki i suppose??)
also im thinking since the harness in my car is OBD2, so i guess the sr i have is obd2??? or how do i find out ??☹
p.s. i saw PFC D-jetro requires Z32 MAF, but i think it is using a map sensor instead of MAF. can some one explain to me ??
thanks in advance guys.
BEST REGARDSSSSS
