Hondata

on the applications chart for the S200 it lists the P72 ECU - The 96 integra GSR has P72 ECU can it be socketed and used with the chip or is it different? the 96 is OBD2 so do I need a P72 from a 94 or 95 GSR?
or are they the same? its confusing when the number is the same.
will the JDM ECU's work on a US car same as a US ECU?

You will need an OBD-1 ECU. Some ECU's [the P75 for example] came in OBD-1 and OBD-2 cars. The OBD-2 ECU's cannot be used with Hondata.

the jdm unit is your best bet since the iabs have the correct polarity for usdm obdII cars.

which one would you recommend using?

it looks like the best JDM ECU to use would be the P72J because it has VTEC IAB and KNOCK ?? AM I CORRECT?

all the obdI jdm p72 have those, but avoid the automatic at all cost.

If I send you a virgin US P28 can you make it work with the IAB VTEC KNOCK and be hondata compatable? or better yet just tell me what I need to do to get it all working right, cus I can socket it and I will need to add my OBD2 to OBD1 conversion board anyway.
my other P28 took a crap and it was converted by hondata.
I hate that bad Idle crap that it has when its cold thats cus the IAB polarity is wrong or not even working right?

adding knock requires a knock board... unless you have a spare board your best bet is to start with a p30/72 ecu.

adding iab is easy for us though. iab does not effect idle stability in any instance i've seen. and the p28 already has vtec.

give us a call this week and we can set you up.

I think im gonna try to find a P72
