Hi,
I'm going to run Haltech Elite 1500 on my FC S5 engine and want to reinstall the OMP because my engine had too much wear by only running premix (I will still continue to run premix with OMP).
The other problem with premix without OMP is lack of lubrication if you are engine braking by letting go of the throttle with gear in.

My question is how the OMP operates in stock form, how much does it flow on idle and different loads and rpm?
I have not powered up the Elite yet and still need to put together the engine but I'm pretty sure there is no preconfigured map in the Elite for the OMP?
How have you configured it?
My power goal will be 550whp.

Thank you.

There is a pre configured map and settings in the S6 base maps. Use them.

Ok! Thanks!
I will check that out.

I'm currently working on setting up a Link G4+ to support the OMP in my FD, and running premix via the OMP using the RA OMP adapter kit and separate premix tank. Unfortunately, the OMP base map that Link provides for the S6/S7/S8 FDs is just 100% in every cell - not very helpful, but safe. If it's possible to somehow post that Haltech Elite OMP map here as guidance, it would be super helpful.

Thanks!

here you go, notice its position it uses a 0-5v sensor like a TPS. i would set it up so that it hit 100% at my target boost, which would be lower than 2 bar/kg, but i think you get the idea

Awesome, thanks! The Link also uses a 0-5V position sensor for the OMP, and it has a calibration procedure so you can get the correct calibration voltages at 100% and 0% of OMP stepper motor travel.

Hoping this OMP map should save me some time doing the obligatory logging & fine tuning since it's probably a better starting point than I have now. When I went thru this drill with my FC, which runs an AEM Infinity and has the same OMP setup with the RA adapter, AEM's base map was ridiculously rich - I had to religiously track my premix consumption and fuel consumption to figure out what my average premix ratio was (i.e., ounces oil per gallon fuel consumed), and then iteratively adjust the OMP map over the course of many months. It's still burning premix a bit on the rich side, but much better than the initial smoke show I started with!

AEM runs the OMP stepper motor a bit differently than the Mazda OEM ECU or my Link G4+ does, so that plus the fact that premix lube has a different viscosity and flows more readily than sump oil may explain why the AEM map was almost useless. AEM runs the stepper motor in a bipolar mode rather than the unipolar mode that Mazda OEM ECU or Link G4+ uses.

if i wasn't so lazy i would have attached the stock metering pump map, Arghx has posted it before.

Basically its Rpm based first and load second, and the other thing is that Mazda is running as little oil as possible up to some point, and then it goes "rich", they aren't running a constant ratio.
