Possible issues from well known vendor's fuel pump upgrade. Mazsport

Sohn OMP
You describe what I have in place Sohn adapter, with an external container. And accessport for higher OMP flow rates.
I still like premix though. It's all through the fuel instead of just at the edge of the seals. The 2008 and earlier cars have 2 nozzles and they are angled out towards the side seals, ignoring the center of the apex.

You Read my Mind, I was thinking about this the other night, but just plain forget about it, is the Sohn OMP adapter still getting sold?? I would like to to it this way than having to mix oil with the fuel each fill.

far as I know it is, but someone PM'ed me the other day asking that very thing, and he said sohn wasn't responding to emails or something. Maybe he's on vacation.

btw, I think cruising and idling are the two points where the stock pcm programming wasn't injecting enough oil. So you skipped premixing when it was important with the old maps.

lower oil injecting point.
The JDM oil metering map have two points in them, where at I think it was at 2000 rpm, that the oil metering rate spikes-- high , like low in the map-- first few?? , like the spike was about the same feed rate as 5000 rpm, and it looked very strange??

Well I don't premix much and only on the track.
How come I can leave my car sit 2, 3 or 4 weeks at a time and never get a clogged fuel pump? I use the Yamha lube R
We still don't know if your gas station tanks have a bad sediment problem and it keeps clogging your fuel pump.
I don't recall people complaining form the MW, NE or West about clogged fuel pumps. I have only heard about the SE and FL area.
How come MM never has this problem? Slave Arm never had it either.
I wish you luck in finding the root cause.

Now, if you pick an oil that is more resistant to burning, does it migrate better around the housing? And if it does that very well, do you now have an engine that is starting to build up oil deposits that will slowly bake into carbon? And if you pick an oil that burns faster, does it leave less carbon but produces a less effective protective film?
Being as stubborn as I am, I generally make my decisions off what information I can collect and piece together. I might find that I am entirely mistaken on how to oil my engine by generally trusting Mazda engineering when mostly out of boost and then supplementing the system when I will be outside of the oiling system's design parameters for a greater percentage of the time. This morning I asked myself - "Self, if mazda engineers were so genius when they made the ecu that the AP is the mother of all management solutions, how did they fail so badly with the oiling system for the same motor?"
Then again, what's more likely? I'll underlubricate my motor and slowly lose compression leading to a premature tired engine or I'll pop a vacuum tube/bork a map point/break something vital and pop the engine.

If you didn't drive on the early flashes then you should be fine...
We know oil was an issue, Mazda corrected it with increased output on the later flashes and increasing the engine warranty.
We know oil is still an issue, Mazda corrected this in the 2009 by adding a third injector. We really can't cost effectively fix this in the older vehicles, so premix will be our solution.

ya, but I would not try going over 350 whp. It just seems like a good stopping point for power on the renesis. I'll let someone else try pushing the limits and seeing how long their engine lasts.

^ easy Jason, I have it
1. route vaccuum line underneath car
2. make sure there are no bends on the vaccuum line
3. remove fuel pump
4. put in new fuel pump
5. make sure it's clocked correctly
6. plug in vaccuum line
7. go race a corvette

i was looking for the instructions to make sure we can uninstall it tomorrow without any hickups. So we'll pull the pump out... but there's a brass vacuum tube that goes up to the front of the car. Anything I should anticipate?

Uninstall should be straight forward.
Remove seat and cover
Make sure you have less than 1/4 tank of fuel and the car is level
Make sure the fuel pressure has had a chance to dissipate....
loosen -AN connectors and remove FP regulator and hose and vac line from regulator
Remove vac line if wanted...or plug the engine end and leave it intact
Remove OEM fuel line connector
Use OEM tool or similar to remove retaining ring.
Lift up pump assembly a bit and disconnect the siphon line ( black/blue connector)
and the fuel level wiring plug
Remove pump assembly.....
Install new pump assembly....
