I am trying to fin out what style injectors the PR3 ECU runs off of. Does it use saturated or peak and hold injectors. I am building an LS/VTEC and if I dont get RC injectors, I would like ot use Prelude injectors. I have been told that the 97+ Prelude injectors are saturated (High impedance) and they flow at a rate of 290cc/min and the 92-96 are peak and hold (low impedance) and flow at 330cc/min. I will be using these with a CRX Si harness. Does this mean that I will need the injectors plugs from either Prelude harness or will the CRX Si harnes injector plugs work? For those of you that went LS/VTEC, what ECU and injectors id you use?

 

If you're talking about the PR3 ECU that plugs into the 88-91 cars, it uses low impedence injectors. And the CRX harness will work. Most LS/VTECs I've seen use stock B series injectors.
good luck,
Jared

 

But what about the OBD-0 issue. I will be uing these injectors in an OBD-0 CRX and I have heard that you need to do a little rewiring when using these injectors in an OBD-0 car. Anyone know what I am talking about?
