I was just wondering if there was anything you can do to an s4 ecu to run the electrical omp from an s5 ? I know i had seen how to do it up here before but i cant seem to find it

Icemark

No.

and why would you want too???

jmkogut

Possibly because he has an S5 parts car. xD

Icemark said it, the answer is no.

I recommend blocking it off and premixing, or finding a replacement OMP and installing it, or rebuilding your existing OMP with an oring kit.

same here.

I personally run a self-rebuilt OMP + .5oz/ga. of premix.

Can't hurt to have extra lubrication.

Thanks guys i was jus wondering but i jus got a complete harness and ecu for an s4 so im gonna use that harness

jmkogut

OH. I see, you're an S5 running an S4 harness... I'm not that familiar with the differences, but I personally wouldn't try to swap generations like that. I'm pretty sure you're going to have shitloads of problems.

you do you know you can get a eomp stand alone controller right ?
So then you can run the S4 ecu and loom and this unit for the omp.

Not to change this particular thread, but what is the proper premix when using TCW3 2-cycle oil? I was told 1oz of oil to 1 gallon of fuel, but the bottle says around 1 oz to every 60 gallons. This makes more sense as the OMP setup burns almost a quart for every 3000 mile oil change.

dude go do a search for premix, its been covered 1000's of time.

the eomp varies the rate injected in regards to load and tps and other crap.

Look again. The bottle probably says 60:1. Thats 60 OUNCES of fuel for every OUNCE of mix.

1 ounce to 60 gallons is 7680:1 fuel to oil ratio. LOL

3k miles at 20 mpg gets you 19,200 ounces of fuel. If you burn a quart of oil (32 ounces) that's 600:1. Nowhere close.

To the OP: BTW, whatever you're doing sounds like a bad idea. Run what the car came with or go aftermarket.
