Replacement option for Oil Metering Pump
Only for those willing and able to do the work....
I found this product http://www.clarksol.com/html/oscPistPump.htm online and thought it would make an excellent oil metering pump. I figure I will try it when/should I ever need to replace my OMP. I thought I would share it since I hate seeing components ripped out of a RX7 and never replaced, and using premix probably isn't such a great solution for daily drivers. Will require creativity and planning to integrate properly, but should certainly be possible.

S4 or S5? To my knowledge, as long as you don't let the oil sludge up completely, the S4 MOP is more or less bulletproof. S5s have the ECU-controlled one that occasionally has issues.
Also, as someone who daily drive a FC with premix for 25k miles, it's really not a big deal. Adds maybe a minute or two to each fillup.

Like I said: "Will require creativity and planning to integrate properly, but should be possible." In other words it is not a direct replacement, it will be a custom setup. You would need to do some electronics work. Here, try this link: http://www.clarksol.com/html/pd-106PumpDriver.htm It is a driver board that converts constant DC voltage into pulsed DC. You would have to make something similar, except instead of the output frequency being changed manually it would change based on a signal from the ECU. See?

********&The pumps are typically powered with 120 VAC or 24 VAC 50/60 HZ. ************************************************** ************
Long extension cord?
To date, I've seen but ONE outfit that can *trick* the series five ECU from going into Limp mode if the original pump is disabled. One. Lotta talk, but only ONE success.

why not fix the original MOP? I'm pretty sure if someone wants to put the effort into it they can fix even the S5 MOP =P If you are going to put all that work into it might as well fix something thats made for the car right.

Here is one of the pumps. Notice the following:
"Supply Voltage - 12, 24, 110, 230VAC,
diode rectified
Frequency - 50/60 Hz
DC Operation: Optional model PD-106 DC driver board"
I wouldn't have posted it if it only worked at 120 or 24 volts, or only 50/60Hz AC. Please give me credit for some intelligence.

Look, I am not saying you have to or should use this to replace the stock OMP, I am just suggesting that if you need/want to replace the OMP, this kind of pump might be a viable option. Don't read to much into this. I just found the technology interesting (as I hadn't heard of it before) and thought that it would be suitable for this kind of application, at least for those who are capable of designing and fabricating things on their own.
Don't give me a lot of crap, people, I don't need (or deserve) it.

Below are expanded descriptions of features that are included with the S5 NA Stage 1 Rtek7 ECU Upgrade. Not all features listed are included in every version. Information on features listed by version can be found here.
MOP Removal:
On the S5 series, the oil injection pump (MOP) is electronic and controlled by the ECU. If the ECU detects a failure of the MOP it will enter limp mode. This makes removal of the pump impossible with the stock ECU. The MOP Removal feature defeats the operation of the pump and detection of pump failures (codes 20, 26, 27 and 37), thus allowing complete removal of the pump. Premix or the more reliable S4 mechanical pump can then be used.
CAUTION: This mod should not be used if you intend to continue operation of the electronic MOP.

One thing I've thought would be a very convenient product with regards to premixing would be an oil injection pump tied to the gas level sender.
Pull into gas station. Pop hatch. Push button. Electronic gizmo goes, "Hm... fuel level sender is here... that means... 12 gallons down. *inject 14oz 2-cycle oil with a little counter so you know it's working* Ok, fill up with gas now!"
All the benefits of premixing, with none of the mess (not that there really is that much).

I work as a machinist at a company that repairs big, simple, industrial electric motors that are designed to be repairable. You do not want to mess with something so small that probably isn't meant to be disassembled anyway, easier to replace.

I think if you could trick the ecu chip, you could just run a vacuum controlled pressure regulator with a return to the oil pan, then have to rig up a power inverter or get the DC option and personally I think it sounds like a big hassle...
However, it seems like a nice pump to use. And if you want to go even further, you could get a separate tank for the pump and run 2-stoke synthetic oil, like AmsOil, and get the burning benefit of the 2 stroke, and still run 20-50 for the eccentric shaft oiling and things.

As for giving you a lot of crap, surely you didn't think you could throw an idea out there without some sort of feedback, did you? I haven't seen anyone flame you in particular.

Ever watch the oil in a omp feed line as it fills up from the omp???? Even if he rpms are in the 2000rpm area and the lever on a series four is held wide open, what you see is a oooching of the oil up the clear omp feedline. It's similar to watching grass grow.
Oooching up the line is a better description than flowing up the line when talking about omp's.
In other words the flow rate is waaaaay, waaaaay, down on the totem pole.
Just a thought thrown out there concerning reality.
