p28 for LS/Vtec.

[GravisESRB]

will the p28-ECU be "plug n play" for my LS/Vtec setup if my car is OBD1?....and what ECU do u use for an LS/Vtec setup if ur car is OBD2.... thanks, peace!

You'll need the ECU that corresponds to the head you got. I'm not familiar with the p28.

yes u can use the p28 ecu. but keep in mind that u have to get it chipped for a dohc vtec setup. like GunNam said, use the type of ecu that'll correspond to the type of vtec head u have. obd1 vtec head = obd1 ecu (p28 or p72). obd2 vtec head = obd2 ecu, and so on and so forth.

if u have an obd2, for example, and u want to use an obd1 ecu u can just purchase a "jumper" harness that'll convert ur existing ones to obd1's.

hth.

Well the p28 is for the 5th gen civic (si?) with vtec so I don't think it would be right for your setup.

I would think you would have to go with GSR ecu (p72 for OBD1) or something like that. I'm not really sure though. I don't know much about ls/vtec's. Sorry

you can chip a P28 to run anything, im running a chipped P28 in my JDM H22..works great, but you do have to have it reprogrammed..peace

If you have a GS-R head and using a GS-R intake manifold you need a p72 to get the secondary runners to work properly. Otherwise a P28 will work fine.

There is a skunk2 obd1/ obd2 converter harness on ebay.

thanks all... i'm getting a OBD1 head, so i guess i'm gonna get the P28 reprogrammed with mugen specs....one more question, do i use the harness for the b16a1 head...or do i use the harness for the p28...peace!

if ur vehicle is obd1 equipped just plug it in and ur all done...don't forget to wire up the vtec solenoid to the obd1 vtec ecu.
