So when i installed my sohn adapter, i decided to test something out. I was interested to see if the OMP would read values above 60 on the oil injection charts.
Turns out , IT DOES.

After i installed my sohn adapter, i put a small amount of seafoam in the sohn tank and flashed the following oil injection charts.

Make sure you change the throttle position first row to 0 and the Engine Load % to 1 (I didn't do the engine load row, but this should ensure the OMP is at 100% operation at idle)

Let the car idle for about 30 minutes running through the seafoam in the OMP sohn tank. At this point you can watch the omp lines gets cleaned out, this is also a good way to verify your lines are not clogged.

Mine where clogged a little bit as the oil would start and stop moving through the lines, but after a while went full free flow.

Now let your car sit over night with sea-foam in the lines. In the morning fill the sohn tank back up with 2 cycle oil.

I left my OIL maps maxed at 100 just to see how fast it consumed 2 cycle oil. In about 40 minus almost 2 inches were missing from the OMP sohn tank.

Found out my omp pump works so good that when its maxed it , if i rev my engine i get huge clouds of white smoke.

Anyway for anyone interested in cleaning your OMP pump / injectors out this is a great way to do it.

Just don't go driving around or high reving with seafoam in your tank.

Note: you can add a little extra premix to the gas if need be to help with lubrication during process

 

Wait you idled the car for 30 minutes with Sea Foam instead of oil. So no oil was being put into the combustion cambers during that time?

 

at IDLE the default values are "3" and the rate the oil is injected into the engine is so small, it almost does not matter too much at idle.

It will not hurt you at all to idle with no OMP oil for 30 minutes at 900 rpm. In fact you could drive you car without the OMP at all, it just wont last that long.

The OMP is to prolong the life of the apex seals.

Many people are driving their RX-8 with clogged oil lines are they are not even aware of it. Mine were already clogged, but still functioning somewhat.

If it worries you that much, just idle till the lines are filled with seafoam.

When people do sea foam flushes, many of them don't even add oil in the combustion chamber. (Your supposed too)

 

Whatever floats your boat, but some oil is significantly different then no oil when it comes to what is going on inside the combustion cambers and idling for 5 or 10 minutes is a big difference than half an hour.

 

The centrifugal force at idle isn't enough to cause the apex seals to expand outward towards the housing. Better than driving around with clogged OMP lines, which many have. Also when you do this, your injecting all the old oil from the lines anyway and at a much higher rate. Takes about 10-15min to clear out all the old junk.

You don't know your OMP lines are clogged till you check, i am already starting to see why these engines don't last that long. Fans turn off too early when driving, inaccurate temp sensor, clogged oil lines, inaccurate oil pressure gauge, faulty coolant level sensor. The list goes on....

 

At idle the pressure of the apex seal against the surface is negligible. You could premix while you do this for extra safety.

Sounds legit, I will try this out over the xmas break.

 

That's what i did, added a little extra premix to the gas just to be safe.

 

Well you didn't include that in the original post.

Again, if you're on top of oil changes and the like, this shouldn't be an issue and if it were, I'd check the lines and replace or clean myself instead of this procedure.

 

That's the best way to do it, but yes i will include that in original post.

 

Any thoughts on mixing seafoam and 2 stroke? Clean the injector and the engine at the same time while driving around? Probably not but I am not knowledgeable about this.

 

Well if you did 50 / 50 mix, but it might weaken the oil a lot. So i don't think its a good idea under high RPM. Either way driving with OMP maxed out will get you pulled over as your car will be followed by large clouds of smoke. XD

 

Lol our local cops are pretty chill so smoke shouldn't be a concern. I believe even if we do a 50/50 mix, with the increased OMP flow there should still be enough lubrication going on in the housing. But my concer is that seafoam may wash the oil film, so may be a 3/7 or 2/8 mix. Also, I believe that seafoam need to sit in the engine for some time. So I guess that might work, but effective cleaning the engine as it does to the oil line.
But anyway, this is actually a good thought. I'll try this soon, I have VersaTune and Sohn. It's always a good idea to clean those lines. ​​​​​​

 

Wow, bird, so cute.

 

99 isn't always bigger than 60 😁

Be careful when editing values outside of the range of inputs the ECU expects. Sometimes it goes up.... and sometimes it defaults to a set value that can be way lower...

 

guess I saw you coming ...
