Hello. I've been busy buying components for this 12A. So far, here's what I'm working with: 4 LS3 coils (7 wire harness) 2 160lb 1700cc Bosch injectors, high impedance BMW E36 TPS (3 wire) FC RX7 13B Crank Angle Sensor (4 wire) GM external mounted 3 bar MAP (3 wire) FD RX7 13B water pump housing/sen...

Ordered crank angle sensor from 86-91 rx7 to replace the distributor with.

Got the 12A and transmission today complete with all accessories.

Correct me if I'm wrong, but I believe the 12A motor has 2 rotors, and you desire to have 4 injectors. You hope that the injectors can be staged. AKA at low HP, you use only one injector per cyl, but then at high HP you use 2 injectors per cyl. Is that what you are asking? Well, yeah, whatever, I k...

I'm eyeing a 12a rotary engine and transmission locally and wondering if I could have multiple injector banks so I could have a large amount of fueling for cheap.

Does microRusEFI support multiple injector banks, if I were to use batch injection?

Yeah, my plan is to wire for the future cam sensor but deal with that later on down the road. I also got 2 awg full copper 650 strand welding wire, copper crimp lugs, marine heatshrink, and I'm about to redo most of the main +12V and ground feeds. Got 8 lifepo4 cells, which I'm making into a lightwe...

i mean, like, I can physically wire the four individual coils to microrusefi and set them as wasted spark in software, right?

So I've procured 4x LS2/LS3/LS7/LS9/LSA Ignition Coils with harness. They'll be mounted on the firewall. Here's the wiring for the included harness, an 8 way metri-pack 150 (right side): ezgif-7-5548268721ca.jpg 5 volt logic input straight from ecu. I'm just going to go wasted spark for now and just...

Got a Supra short shifter, 18oz weighted shift knob, and solid metal shift bushing installed. Solid and robust. https://uploads.tapatalk-cdn.com/20200308/2e8f48660cd4c669ae161f059a7cda96.jpg https://uploads.tapatalk-cdn.com/20200308/161bf30212f5e7aa9f8f02759acab883.jpg https://uploads.tapatalk-cdn.c...

Hello. I have started this thread to showcase and discuss my project, which will utilize microRusEFI.

Doing a 12A swap in my 1984 Celica GT.

Thank you all.

Any news now?

Any news?

Nice to hear, I've been checking this thread every few days to see if there's been progress, so it's good to see some.

Sweet! Keep us updated!

I can't guarantee that's your injector size, but I'm 99% sure it is. If you have any trouble with it, let me know and I'll tell you some other possible sizes, since they varied from year to year. I'm willing to be 23.2lb is correct though.

That might help. I dunno. Flow rate for yours should be 23.2lb/hr injectors.

Oh, I actually meant to say anti-lag. I sometimes accidentally get them mixed up. You know, retarding the timing so you practically turn your exhaust system into a pulse jet, spinning up the turbo without actually making power, so there's no lag.

Another really neat thing to integrate would be two step launch control. And yeah with what Jared said, that's where fully sequential ignition would be nice, with knock protection.

Another question that 34blazer brought up, is barometric correction or knock detection/protection planed at the moment? If not, how hard would that be to do? With the OEM dizzy setup, do we have individual control over the ignition timing of all 8 cylinders?

Haha yeah, I'm not expecting you to go the easy route, and I admire seeing people do the hard things for the benefit of others. I'll probably go with an external setup for my alternator, MAYBE, or at least expedite it with some other way. As for TCC/OD, I'd imagine you wouldn't want OD to always be ...

This might sound crazy but I feel like, if the chip supports it and it isn't a big deal to support it software-wise, what would really be nice is if there was support for fully sequential injection and ignition on up to 12 cylinders, WITH room for extra IO. Or at the very least, fully sequential ign...

Lol, that's what I was saying to do earlier.

The problem is, if you only have one low side driver left... You'll need three since the governor, TCC, and OD are all low side solenoids.

If I could go ahead and get a Frankenso, I'd like to do exactly what Jared is doing and go ahead and start. Use the factory stuff for testing and prototyping, then once it's reliable and we have stuff figured out for the most part, I'd go ahead and hardwire everything the way I want it. If anybody h...

the MAP is generally linear AFAIK, but the scaling is standard for every calibration I ever looked at.. The MAP on these trucks is a standard 0-5V 1 bar sensor, I think earlier OBD1 Chrysler engines used a standard GM MAP. Keep in mind the initial baro read and pseudo baro read to set the baro scal...

That's a good point, lol. Alternator is probably gonna be the noisiest thing though, I dunno.

I would avoid controlling the alternator with the ECU. The easiest, noise free way to do this is to use an old school external regulator. The volt regulator is kind of like a pulse, activating a magnetic field through grounding of the unit, keeps noise out of the ECU if you go this way and it lasts ...

Meanwhile, this is what I did Saturday. Best pass I could get out of mine.

1/4: 17.279s
1/8: 11.225s
Trap speed: 80.87mph
60': 2.691s

I'm sure with some better tuning it should see 16 second times, maybe.

My mouth is gaping open. Just read this thread. I had been going back here, refreshing it, hoping you were gonna reply, but I had no clue you were already well on your way to having it running! Honestly I'd like to thank you, this is a huge amount of encouragement for myself, and I'm extremely excit...
