    whats up guys i have a 92 hb with a jdm b16a and am ruuning a p72 but i need the p72 for my other hb and am forced to use the p30 with b16a

    my ? is i was looking into the ecu out puts and there are two different outputs

    p72 p30
    A17 iab solenoid nothing
    b9 starter signal clutch interlock swith

    i was looking to see if either one had some were else to rewire it but it like the iab soleniod does not even on the p30 and there is no starter siggnal for the p30 and no cluth interlock on the p72 so what can i do to make this work

    please help

    seing as how your b16 doesn't have iab's anyways, i think you'll be fine ;) as long as they're both obd1 ecu's, the p30 will work better for your b16, it has the appropriate timing and fuel maps, the p72 is for the gsr b18, you should have swapped them a long time ago ;) b9 is the starter signal for the p30 and the p72. are you sure you weren't comparing the p72 pin outs to the obd1 jdm pr3 pin outs, because it doesn't have a starter signal at b9???

    as long as they are the same obd, there is 0 wiring changes.

    you sure about that? or it just feels slower b/c you can't rev it to 8.5k any more ;)

    p72 and p30's have close to the same redline... and the p30 shoudl give your b16 a better fuel and ignition map anyway...

    have you checked the timing with a light, or just moving it around? if your idle is surging up and down, sounds like it could be your iacv.
