hello, been searching all morning for solid info. Is that 96 prelude with the obd2 p13 ecu run the 345cc peak n holds or the 280 saturates? The p13 obd2 is a rare one so i was not sure if this info was correct because of its on board diagnostics

1992-96 Prelude VTEC Peak and hold 345cc Same with that obd2 p13?
1997-up Prelude VTEC Saturated 280cc

if this is true... then using the obd2 p13 in your A4 is a bad idea right?

 

obd 2 motors use 290cc saturated injector. obd 1 use 345 peak and hold. there ya go.

 

im looking at many engine bay pics of preludes, all 96 and all of them have a resistor pack, whats with that.

I know this, however, that 96 computer thats obd2, its in cars with resistor packs in the bay. hows the obd2 p13 a saturated computer if the car has a resistor pack?

 

what engine code do you have? h22a4 runs saturated. h22a1 runs p & h. p & h use resistor pack to bump up the resistance so the ecu can read it. saturated injectors already carry the proper resistance.

 

lol, i allready know this, maybe im not being clear about what im asking.

1992-96 Prelude VTEC Peak and hold 345cc
1997-up Prelude VTEC Saturated 280cc

we both agree on this right? or 290cc whatever you said, either way.

we would also agree that 92-96 is obd1. and that 1997 and up is obd2. problem being in the last six months of 1996, they switched over to a obd2. The above statments may or may-not be true.

obd2 says saturated
96 says p&h

welp, ive got a 96 obd2. follow me?
back to my question, obd2 p13... is it Saturated or is it p&h?

 

you can check the resistance to be sure. obd2 should be saturated. resistance should be about 12 ohms across the terminals, peak and holds are 4 ohm. i do understand what you are saying, it's probably myself that is making this more confusing than it need to be.
i'm going on the fact that you said you HAVE this motor. resistance won't lie for sure.

 

I remember checking the part numbers on slhondaparts a while back, and I believe the part number for the H22A1 injector stayed the same for all years.

exactly what i should have done from the beginning, why didnt i think of that?
thanks for your help

 

i'm glad we figured out how to speak to each other......technically. next time we'll know
