Two things caught my eye, that I need help understanding.

The Legends stock injectors are peak/hold. The RL are saturated.
*Use Legend injectors for swap*

Oil filter. What shaft are you refering to?

Thanks man! This is a document I was working on for the last year or so, a little here and a little there. I busted my hand open sunday night and needed 7 stitches so I've been out of commision, but obviously I can still type. I decided to finish it up.

EDIT: DV8 You're right.

On the oil filter shaft I meant the threaded shaft the oil filter screws on to... I don't know what its proper name is :dunno:.

P.S.
PLEASE PLEASE if you spot anything that needs to be edited or additions that need to be made, please post them up. Also for Quaraxkad, please add this to the wiki... I would have like to format it a bit better with tables and what not and add a summary so my customer's can have a reference.

No, I had it right.... Legend injectors ohm out at 12-14ohms, which is saturated, while the RL's ohm out at 1-2ohms which is peak/hold.

I dont mean to argue. Legend injectors system is setup for peak and hold, there's a resistor box. They operate at 2ohms. When choosing larger injectors a peak and hold is what you look for. For saturated you need to eliminate the resistor box and probably switch to an EMS.
I emplore you to grab both Legend and RL injectors and check their resistance, you'll see the Legends are 2.0 and the RLs are around 11+

As far as I can tell, there is no resistor box for he RL, so they must be saturated injectors-hi impedence.


"
These Honda fuel injectors are solenoid-actuated constant-stroke pintle type consisting of a solenoid, plunger needle valve and housing. When current is applied to the solenoid coil, the valve lifts up and pressurized fuel is injected. As the needle valve lift and the fuel pressure are constant, the injection quantity is determined by the length of time that the valve is open (ie. the duration the current is applied to the solenoid coil). The injector comes with a filter cap, 7.3x2.2mm o-ring, cushion and seal rings at the top and bottom respectively. These seal rings also serve to reduce operating noise.

When self-diagnosis check engine light indicates code 16, there is a problem in the fuel injector circuit. The fuel injector must be replaced when the resistance is less than 1.5 Ohms or more than 2.5 Ohms between the 2 terminals of the injector. It must also be replaced if there are any internal leakages within the housing."

As for the oil filter shaft; is its apperance different? Legend filters fit mine normally. So I dont understand whats different.

My bad... Let me go back and edit.

Did you use the Legend oil pan by chance? The RL uses a different oil filter and when you try to put a Legend one on an RL it just slides up and wont catch any threads because the hole is larger in the filter.

From my build thread long ago, helps explain using RL injectors. For people like me who do better with pictures than words.
I want to use the RL injectors (High Impedence) instead of the LEGEND injectors (Low Impedence) so this is what I had to do. First thing is getting the RL injectors to fit in the stock legend wiring harness. Here are two pics of what is required.


here are the sides of the RL injectors. The one on the left i have already modified to fit the legend harness by shaving the side tabs.


Here is the front of the RL injector. Again, one on the left is one that has already been shaved to fit legend harness.


The wiring changes are super easy, so long as you understand how the injector ciruit works. This pic shows how the circuit works. The BLUE lines in the pic show wires that are to be CUT and spliced/soldered together.

Being totally honest, i don't remember, but I obviously must have changed because of that issue or related to something else. I still buy 8212 filters. What do you normally do after a 3.5 swap, just use the 3593 filter?

Taking nothing away, I guess swapping the pans is doable eh?

^ back when u did it, i would have done it as well, ah the good old days of having the NSX filter readily available.

Here's a preliminary wiki version. I'm not thrilled about the layout at the moment, it's a bit jumbled.

Genearlly when you see injectors with resistors it means they are not peak and hold. For the C32A injector, using an Autronic ecu , the ecu drives the injector without a resistor in low current mode. This indicates a saturated style injector. The Autronic ecu has internal current limiting, the factory ecu uses the external resistors for current limiting.
