I was wondering if a Haltech can control an electronic metering pump for an 89-91 RX7, and i think that the 93-95 use the same setup. Any information will be appreciated, thanks.

I thought the FC's were mechanically driven OMP unlike the FD's which were electronically metered.

the 86-88 FC (series 4) uses mechanical OMP, the 88-91 cars use electronic. as yet no the haltech doen't support it however it is in the pipeline for future software upgrades so we are told.

Andres,
Did you just use an 87 OMP, or did you use the whole front cover? Did T&R do it?
I'm seriously considering a Haltech, but premixing sounds like a hassel. How much do you premix? Can I put an early 2nd Gen. OMP in my FD so I don't have to premix? What are the advantages/disadvantages? When is this Haltech OMP software supposedly coming out? Thanks!

For most road cars you will mix 1-1.2 ounces per gallon of gas, this will yield a 100:1-128:1 ratio. It really isn't a hassle because you just have some little soda bottles filled with premix that you can fill up each time you come back from the gas station and then have them ready for the next fill-up.
Yes you can put an 86-88 mechanical OMP on your FD, just ask Andres, or T&R Racing. Or there are others who know as well of course
Advantage:
-No premix, just start and go.
Dis:
-You are burning 4 stroke lubricating oil from your sump which burns shittier and fouls things.
don't hold your breath for a computer that controls that dumb thing

same as andres. i use an 88 mechanical OMP. it will mate to the front cover with just ine extra bolt installed. runs perfectly well and eliminates the hassle of premix. i really like the haltech, but it was a bit too far from a stock car when you have to add premix everytime you fill up. plus, as someone said, the electronic OMP has problems. the valves are supposed to be one-way, but they go bad a lot and go both ways (switch hitters?). when this happens, you aren't getting the oil you should and there's no light or warning that they're bad. -gordon
i'll put it bluntly, the OMP weather it be controlled electronically, mechanically or by some martian mud monkey following you around in his UFO, is crap. it is only there as a make shift measure so you dont have to premix from the factory. Mazda reccomend you premix with a rotary engine, the OMP only came about for non enthusiasts who want the car as nothing more than a means of transport and dont see the whole rotary engine/performance side to it.
You are doing your engine a FAVOUR by ditching the OMP and running premix.
god do i love these posts. in other words, a real man uses premix... a real rotorhead lubes up his gas... sticks some fluid down the pipe... OMP's are the viagra of woosey 7 owners... yowzuh. ya gotta love it. -gordon

Exactly, i just have the external plastic casing from the heater unit, everything is blocked on it except the pipes which go up to the windscreen to demist it. air cond box is the same.
