jdm b16 with p72 ecu vtec problems

[junhonda20]

Hey guys i just got a jdm b16 sir II into my 95civic ex ... i used the ex harness to hook everything up to the obd1 p72... THE MOTOR IS RUNNING ok for i can see and feel but it's idle's rich and when i turn on the car it will surge at 1500 rpms until it warms up .... i also think that my vtec is not opening although i feel like the car has pretty good power.. I am a bit confused when it comes to wiring??? I read the i had to rewired the knock senser and some other things in order to complete the swap....... I REALLY DONT WHATS GOING ON HERE THE CEL NEVER SEEM TURN OFF... Thanks for the help......

wrong ecu, i think..you will need a p28

jump the CEL connector near the computer and follow the light blinking to find out what codes you have

 

[lsvteccrx]

actually your best bet is to keep your p28 and get it chiped to run your b16

 

[slammedcivic]

he doesnt have a p28 he has a p72.. he should get a chipped p28

yeah you r car has the gsr ecu, so it's looking for the secondary butterflies.
I concur about the chipped p28 for tuneability. That p72 is running integra fuel maps so that's why your car runs the way it does.

as fas as i remember the p72 will not throw a code for the secondaries if they are not hooked up.

Why not just chip the P72? It runs the exact same code, since it is essentially the same ECU plus a knock sensor board and secondary control.

A HELLL OF A DIFFERENCES !!!!!!!! ... my CEL is still on i think is because of the knock sensor..... but before the car hits v-tec the car cuts off or lag a bit then it just rips to red line...... any info ???????

why not just hook up the knock sensor?
