F20C Fuel Injector Impedance/Type?
Do we have high impedance injectors or low impedance P&H, stock? I'm guessing high impedance, since it's what most Hondas run, and I don't recall seeing a resistor anywhere under the hood...

I'd say high impedance as well. I don't think any Hondas have run low impedance since the early 90's. But, I'm just guessing. You could always throw a multimeter on one of them. Low impedance tend to be in the 2-4 ohm range, high impedance in the 12-16 ohm range if memory serves.

The '96 H22A IIRC was the last Honda to run P&H with the resistor. If not, then it was '95 (know that one for a fact). Not sure about the F22 and H23 mills.
Greg, don't know about you, but I don't keep my manual up here at work.

If anyone has one out or is under the hood soon they can check.
If you have a voltmeter with an ohms setting you can check it. Pull the electrical connector to an injector and measure the resistance.
High impedance would be 12-16 ohms and low impedance 2-4 ohms.
I will check this weekend when I have a little time if no one has before then.

AEM says they are high impedence.
RC Engineering has not bothered to return my call or email so I don't know size, but their injector size calculator says we must be in the 410 range.
