I just bought a car that came with SiR ECU. What car is that from? Also will someone kindly list what P72, P28 mumbo jumbo stands for? Help a newbie out.

Also what does SiR ECU redline at, vtec crossover?

Thanks.

p72 GSR
p28 SOHC Vtec 92-95
p30 DOHC Vtec Del sol or SIR II What you probably have
Pr3 OBD-o SIR

 

SiR II is the JDM civic EK model...170bhp...redline is 8000rpm fuel cut off is 8600rpm

 

if it's a Teg SiR, then it's just a GS-R model. not sure if SiR is limited to a certain vintage that would tell u if it's P72 or P73. those are the different ECU's that come stock on the GS-R based on whether it's pre-98 or '98+ model. i'm not totally sure, but i think P72 is OBD1 and P73 is OBDII.

the other ECU types like P28, etc. are for other hondas.

 

Thas incorrect, the SIR II is the 92-95

 

just get an obd1 wirring harness and p28 chip
