Oil metering pump
Ok so im trying to decide on a full standalone and i know a lot of them cant control the omp on my s5. So i wanna hear your guys opinion, is deleting the omp and pre mixing a good idea or a terrible idea.

Personally I have an S5 TII in my s4 with a Haltech and I run premix.
The only downside I find is telling someone who asks" what are you puttin in there"?
I find it funny as you see people putting in Gas additives all the time..I guess we are Special.
Check with C Ludwig( Haltech Dealer) and see if any of the Ecus will control the S5 OMP off the Pwm circuit.( I hope that is the right term).

the better haltechs will drive it.. not the sprint
.. if you have a primitive ecu.. or swapping the s5 motor into the s4 car and s4 ecu ( or is running LPG mixer on a late engine )
.. then the standalone EOMP controller ( by jason dixon ) is intended to run from a spare TPS.. an ECU output TTL signal .. or an included map sensor and runs independent of any other system
he hand makes them hobby style and can be tricky to get hold of at times but the units do exist and do work AOK ( i done the trials and a lot of the research )
and i dont think there is an equivalent out there..
( well ,, beech aircraft made an equiv for aircraft 20bs after we started posting vids of the eomp inoperation )
PS
these are 5/6 wire stepper motors with feedback ,, most ecus run them in a moddified 4 wire stepper method.. this ties up 1 input and 4 outputs from most ecus.. hence you can see why the option isnt on any old ECU
.... the only thing that will run from a PWM ( TTL ) is jasons controller

Is the jason dixon one from australia? That one looked pretty sweet
Optional Extras : Spare Eomp Controller Handset
I think its good to have both. Premix for spirited drives and let the OMP do its thing for daily light duty stuff

Ya I'm pretty sure power fc can control the omp but I was leaning towards the aem ems 4 or the haltech sprint re as those two are much more in my price range. Can this external controller simply be added to any ecu or what's the deal with it.

as above.. it can run independently from its own supplied map sensor or from a TPS signal or from a TTL signal ( a mapped output from an ecu )
it uses 0-5 V as an input signal for the amount of engine load ( the input signal can be inverted at a menu selection )
and it allows the user to set the output scale during calibration,., allows the user to use an offset and allows the user to choose a decay pattern
ie .. set max amount ,, set min amount ,, and how long it hangs while you come off the load and spreads this across the range of input signals it will see
sounds complicated but is pretty simple., the offset and decay allow you extra oiling options for stuff like run in or aftermarket seals and you dont really have to learn to map it unless you wish to do so from your ecu
else.. it can run fully mapped off an aux output from an ecu
( takes up only one aux output from ecu instead of 4 and 1 input ,, and will probably run off the injector duty but i would expect mazda staging to make that a bit funky )
hmm .. it also can run the rx7 EOMP ( s5/s6 ) like the series 7/8 and rx8 EOMPs ( rx8 mode ) and thus eliminate errors/ deadband in the feedback senders
the tricky bit is tracking him down and sometimes there is await till he churns out a batch .. various evolutions out there as he struggled to find a case and wiring to suit etc
methinks he is currently trying to work something out to get around the rx8 self checks so that its handier for s1 rx8 owners

How much money does it cost to run the premix before doing your oil change (3000 miles)
I was thinking about pre mixing and just buying a case of whatever 2 stroke pre mix oil, but the main concern would be the cost.
Obviously not pre-mixing and using the stock omp is cheaper.

Im leaning towards just premixing and deleting the omp. It really doesnt bother me to add two stroke to my tank each time i fill up so and it gives me way more options on ecu's that i can run

no idea about ALS apex seals, in a t2, you should ask ALS.

Ya ive heard its just 1 oz per gallon of fuel. I mean all the other money im throwing into this car 6 dollars more for 2 stroke oil isnt gonna make a difference.

I'd think for just normal street driving with semi frequent spirited driving I'd use a similar amount.
Is using too much a bad thing ? I'd think too little would have worse consequences than using too much. I wouldn't know though.

I wonder if they have anyone representing them on here.

its nothing bad, if that's what you're wondering

about the worst consequences are blue smoke and plug fouling.
in the '80s 2 stroke dirt bikes we would run between 32-40:1 premix(roughly 4 ounces per gallon) but we also changed the spark plugs about every 40 hours, which translates to about 1000-2000 miles on the street. they would foul if we didn't change them periodically before then. the whole exhaust systems would also foul with unburnt oil but that is just how it is. 1 ounce per gallon has almost no ill effect, 2 ounces and above you start to see the results of oily exhaust and plug fouling.
i have never seen a detriment to using too much premix aside from cooking the spark plugs early, and of course people behind you reporting you for the smoke. but on the track smoke is perfectly fine unless you're laying a smoke screen for other drivers.
if we changed the premix ratios from even 32:1 to 40:1 you could instantly tell the engine was running hotter and the carb jetting was getting thrown off.

I'll do some research to see what I'd go with, I want something good but not super expensive.

opposite, it will make the car run rich because the ignition won't be able to burn the fuel and produce power. the only way you can run lean is by injecting less fuel, which is the ECUs job to calculate from the amount of air entering the engine(fouled plugs will not affect this calculation).
but there is no joy changing spark plugs in a parking lot on a hot day.

I might keep the power steering, just because I dont want a half assed power steering removal like my last car had, which was basically removed the pump and hoses, but nothing was sealed off. It never locked up or anything but I'm sure I could potentially have later run into problems.
It drove fine, it was only hard to turn at a stop , but if you have muscles its kind of a workout to drive with so I liked it. Lol
