you should be able to i could be wrong, but the driver is looking for 12-13ohms of resistence, either with 2-3ohm injectors and the 10ohm resistor or the 12-13ohms through the sats.

in theory it should work.

People use saturated injectors in CRX's all the time. That is what you are talking about "low impedence wise" correct?

i have never done it and havent really paid attention to people doing it. i thought of it more in terms of not goin obd1 in an obd0 car, but using sats in an obd0 car with an obd0 ecu.
thats why i was a little gunshy about posting that it will definately work.

I personally wouldn't try to run saturated injectors on an ECU that's designed for peak and holds. Now if you're talking about running saturated injectors in an OBD1 converted EF, you can do that no problem.

i am going to play devils advocate, why do we run p and h on saturated ecu's? he hee

Honda ecus do not have peak and hold drivers, even the old ones with injector resistors.

It's very easy to run saturated injectors on a computer that came with low impedance injectors. Just remove the injector resistor and tie the 12v signal wire to the rest of the injector wires.

Because they don't make saturated injectors big enough.

Well not including the new Bosches (sp?) that is.

After hearing what Tony has to say, I guess back in the late 80s early 90s peak and hold injectors may have been more readily available?! I don't know why Honda would run a peak and hold injector on an ECU with saturated drivers. I figured they made more sense than that.

yep. he speaks the truth. 88-91 civic/crx guys do it all the time.

hmm. well here's some specs on the 2 types anyways

thanks a lot guy, i will just tie the 12v signal wire to the rest of the injectors wires. car is a 95 honda accord ex running stock ecu.

So why are some resources stating P&H on the 90-91 Integra, 88-91 CRX/Civic SI, 92-96 prelude SI and 03-07 V6 Accord?

If they had peak and hold drivers then they wouldn't have injector resistors inline.

What's the reason of using p&h injectors if they werent even current limiting them?

No idea, i'm sure it had to do with what was available at the time. Things have come a long way since the mid 80's.
