I posted this here because when most people go single turbo, they usually run a standalone and lose the omp. After many years I think I may have found a solution to premixing. I've been converting regular piston engines to LPG and also been installing a cheap valve lubricating system which is vacuum pulled from a plastic bottle or tank via a drip glass. Now they came out with a small electronic system which is software adjustable(mappable). It's a little expensive and I don't know all the details as of yet as to what ratio's it can be adjusted for injecting. For our rotaries I know that we premix 1:100 whereas for valves(piston) only need 1:1000 oil being injected. I personally hate premixing at the gas station, I never liked getting out(no self service here in Greece). Anyway, here is a link for the system.

Well smack my *** and call me Suzy...It's about ******* time someone made it!!! Although that works with the stock omp and pulls oil from the oil pan. Guess I could get a Sohn adapter!

lots of standalones have stepper motor outputs to control the OMP

Some of us have gone to using the OMP using a seperate oil tank using 2-cycle oil.
(1) uses clean oil made for this type of lubrication and burns cleaner than the normal oil.
(2) uses the stock OMP and ECU control that is reliable and does not cost more.

Obviously any decent ecu these days will run an electric OMP, but for those who have a microtech or ancient haltech, are looking at fitting a gas carb & dizzy or basic ecu, or running carb & dizzy on newer block it gives them an alternative to premix.

EXACTLY!!! I personally like my E6k and don't have any plans in switching it out for a newer one. That really is the last piece of the puzzle. Btw, I think this unit is better since you can add more oil for better protection. Let's say for the RX8, Mazda's flashes actually make it inject less oil which leads to a lot of engine failures, this thing is perfect!

here is a little peek
new code is developed to allow it to work from any analog 5 V load signal
also has a new rx8 calibration mode that will retro work with older EOMPs and those with faulty feedback wipers



the possible uses just keep stacking up-

mixer LPG fueled late model engines

s5 motor into s4 car without s4 timing cover and TB retrofit or a swap to s5 ecu

microtech conversions on late engines using stock timing cover and no premix

frees up all those stepper outputs and feedback inputs on the better ecus
( cheaper than optioning up to the ecu with more aux functions )

in development-
,, CEL cheat for stock rx8 , while having custom OMP rates ( and hopefully s5 given time )

digital PWM to analog converter, allows you to use the digital aux out on most ecus to 2d or 3d map the output

dave at speed one has done this already with a oil catch can.

mistral engines apparently also developed one also for their light aircraft rotary engine packages
i bet theirs is a bit more expensive though !

on a further note with the jason dixon eomp controller
,,mine is running now from a ( GM ) map sensor and has some new beta code revisions that will be unleashed soon
new modes allow for different styles of calibration ,invert, decay profile and trim if required suit other load sensors

also-
PWM to analog convertor is on the cards to allow you to 2d or 3d map from any aftermarket ecu and use PWM aux out to command the eomp with a single aux out wire

where can i buy this omp controller , been looking for something like this.

i'm ready to paypal , tired of premix.

http://eomp.info/

the website looks as if it hasn't been updated 2009

and does it have a feature that tell me if the omp is still pumping?

bumpstart

site is currently under revision, expect new vids and a clean up soon
contact jason via his email
sideseal22@yahoo.com

new units have a warning buzzer in them,,, they will not fail and inject no oil
,, if there is any faults the unit will stay in its last metering position
( which is always SOME oil )

currently some code updates going on,,, new calibration features and warning buzzer

Hey I emailed , but still waiting on a response shipped to florida how much

bumpstart

give him a couple of days to respond

1: this is his hobby, not his full time occupation, he is not a shop with people to pounce on your email
2: when you send , he is 12 hours ahead of you into the day ,, do you open mail when it arrives at 3am ?

i am working with him 2 or 3 nights a week to finalise some code and conduct some beta testing on new features we wish to include free for the orders already taken
there is currently about a dozen units going through in this batch
-rushing them will mean you will get one without the new features

given a week or two this will all be finalised
and those who have registered interest and or requested purchase in the last fortnight will be in on the latest revisions

BTW,,
stock map sensors and GM map sensor have already been proven on this device and we are also getting the documentation together to demonstrate the delivery curves when you select various map sensors
EG
i am currently using an N327 map sensor to get full delivery by 2 psi ,, and excellent definition in the vacuum scales

N318 map sensor in comparison is full delivery at 8 psi ,, and so would be set up in the menus with initial bias offset to be at a similar rate at mid scale signal
( else it will be very frugal with the delivery )


-----------
ATM we are contemplating doubling up the driver chip for more functions regards the CEL defeats for driving late rx8 OMPs
and also regards to taking BOTH the TPS and the MAP sensor ( or MAP and AFM )
inputs to average to make the 5V load signal in view of getting an even better 3D interpretation of engine load

this unit is potentially on the cards for next year,, stay posted
