I have an OBD0 91 CRX with the PM6 ECU. Would it be better to get a PW0 or PR3 and disable VTEC, or convert to OBD1. I know OBD1 is a lot better for tuning but what does the OBD0->OBD1 conversion involve?

Thanks

turbo setup? OBD-1 is better, and AEM EMS is cheaper withmore features

Hoosier Daddy

Turbo of course. Built LS block...looking to get the most out of it (around 12lbs?)

I thought AEM EMS went for $1,000-1,500.

Thanks PHiZ.

So I'm going to have to buy new injectors?

PHiZ

here's the thing, and I freely admit that this is bad advice,hehehe
I'm not 100% sure.

I started to give advice, but then stopped. When I did this, we HAD a full OBD1 engine, and dropped it into the chassis. You're converting the engine itself.

You need an ecu x-over harness OBD0->OBD1
convert to 4 wire O2
New distributor
(new alternator??? dunno)

As for injectors, plenty of ppl run DSM injectors (peak and hold??) through a resistor box. So I don't think the ECU cares, as long as you have/don't have the resistor box for whatever application your injectors expect.

(I think that part sounds reasonable, right?)

How crazy is your setup? You might be able to get away with using turboedit, or if converting to OBD1 uberdata.

Thanks PHiZ, I'm running DSM's and of course already have a resister box. This is my setup:

B18a block bored .20 over.
JE Pistons
Eagle Rods
STR block guard
EF1 L28 cams
Skunk 2 cam gears
Skunk 2 intake manifold

I'm tryin to get the most I can out of this.

Definitely convert to OBD1! With and OBD0 PR3, you'll basically always have to run the setup in open loop since it expects to have twin 02 sensors up on the manifold. I was going to do this initially (OBD0 PR3) since I was only gonna drive my car at the track, but I find that I'm driving it more on a day-to-day basis, so OBD1 conversion it is. Additionally, there are a lot more features for OBD1 Hondata ECU's (nitrous control, 2 auxiliary outputs, disable knock sensor, eld, etc)

Something else they you may want to consider. The PR3 and PW0 ecus are getting more rare these days.
