just what it says, what ecu will give me the best power gains. would i be able to use a obd0 vtec ecu and engage vtec from it?

 

none of them...either way your going to have to use an rpm acticated switch to activate vtec, unless u go obd1. The teg ecu is supposed to have the best fuel and ignition curves for the SOHC. So get a pg7 and rpm switch and go.

for a SOHC VTEC u got a few options

1- u can go OBDI conversion and use the right ecu P28

2- u can use a OBDO PR3, PWO B16ECU chipped but u will have a very high and dangerous redline ( u can chip these and make vtec kick around 4500-5000 etc)and change programs like Mugen, Toda, etc

3- u can use any OBDO ECU PR4, PG7, PM6, and use some sort of vtec controler (Apexi or Field's)


4- u can get a Zdyne 1 wire conversion ecu

5- or u can just get Hondata for the OBDO cars....

from all of them the Zdyne SECU or Hondata on the OBDO or OBDI will be the best

 

I'm using a automatic PR3 on my mini-me. I'm hoping that the less aggressive mapping of the auto ecu won't make the engine run so rich, and the rev-limit on the auto ecu is lower as well (7400 rpm, I believe). I haven't put the car on the dyno yet, so I'm not real sure how this route of engine management works out.

Of course, you have to run that STUPID twin oxygen sensor setup if you go PR3.

not unless u chip the ecu

Yeah, for now the car runs a little rough without the second O2. I don't know if I'm going to rechip it or just install the second O2.

 

if you can get your hands on a pr3/pw0, just use turboedit (www.turboedit.org) to chip it and lower the rev limit to acceptable levels and import some z6 maps. that way you have pretty much a p28 without the hassle of a wiring conversion.

 

Or you can go to pgmfi.org and download the latest version BRE which also supports pr3/pw0.

I've run the auto JDM PR3 DOHC ECU on my SOHC VTEC swap for some time. It run very well. I still have the downpipe for sale with proper O2 bungs locations.
