I got a 93 ej1 vtec that I'm going to put a 2001 GSR motor my quetion is what ecu should I use?The one that came from the 2001 has the immobolizer feature,so I was thinking I could use an obd1 p72 or get my p28 chipped.

get a obd1 p72 or a chipped p28

[jvillagran2000]

get a obd1 p72 or a chipped p28
yeah that what I thought,the motor should run fine with an obd1 p72

[Dirka Dirka]

chipped p28 much cheaper and you'd get to play with fuel maps and your vtec setting. :goodjob:

Yes it will be fine, but you will have to do some wiring, to repin the dizzy, as well as add things like butterflys,knock, etc...

I just want my car back to 100% stock!

If I was going the P28 route,but I should be fine with an OBD2 P72 and just rewire the knock and vtec.

p28 all day

[EmminoDaGreat]

well if you go p28 you dont have to wire shit, except re pin a dizzy, since its obd2.... you can turn all that jazz off.. but if you use a stock p72 you need to do what I stated.

wow really so I would be better off using my p28,I might have to bring it your way to get it chipped or get it work.

[jvillagran2000]

I guess I forgot about the obd2 dizzy,I thought the obd1 ecu would be PnP.Is there any info on how to add those wires and repin the dizzy?

[EmminoDaGreat]

Everything that I've read says that the obd1 p72 works with out modyfing to many wires.But you do this for a living so your have more experience than me.If I run into a problem that I can't figure out I'll bring it by the shop...if thats okay :D
