RT 4WD Auto Trans ECU Question

Does the D16A6 4WD automatic run a PM6? Or is it a PS9 like the EX sedan automatic?
I'm sure somebody has one, if they can take a peek that would be great.

Anyone know how to tell the difference between an auto and manual PM6?
What I'm really looking to do is the single wire vtec (have a Y8 head sitting around too) and still keep my A/C. I know it's possible to do that with a PS9 but they're not the easiest to find and a little beyond the price of the PM6.
Ideally what I would like to end up with is an A6/Y8 mini running OBD0 with two separate fuelmaps set up to switch between pump gas and E85. Although the easy and cheap OBD0 MPFI D16Y7 is looking better every day. The price I can get that motor for is less than the tuning tools I would have to use for a mini-me.

this is right out of the 90-91 civic wagon electrical troubleshooting manual
Now with that said the part numbers for the automatic and the manual trans4WD wagons ECUs are NOT the same as each other nor are they the same as the CRX Si or the Civic Si...also not the same as the manual trans Civic 4dr EX ECU but all of those are PM6 middle numbers. maybe the same programming or maybe close enough not to matter much.
Of course California emission car ECUs are different from others.
If you want, I can post the exact catalog part numbers for each.
So it looks as if I would have to find a PS9, give up A/C, or rig up and RPM switch. I think the best way to go would be picking up a good used D16Y7 and get the E85 tuning right. Then later finding the PS9 and building a good A6/Y8 mini-me and tuning it a second time.
I'm going to have to do something soon, I've noticed the D15 starting to smoke a little until it warms up to temp.
Help me help you....
specifically what is it you are wanting to accomplish?
what do you have now and what do you want to convert to?
keeping a/c?
is it automatic trans?
is boost is the future?
And having about 130-150 ponies under the hood would be nice too.
Well, I have a Y8 head and was going to put it on an A6 block. I have the head and I know a guy with a block for next to nothing but I would have to have it freshened up a little. It' one of the better mini-me combos. I was planning on keeping it OBD0 and running a moates two-timer. One prom for pump gas and one for E85. With it being OBD0 I was thinking about using the output for the auto tranny converter lock-up for vtec activation, I know some people use the A/C for this but I like A/C and plan to keep it. The auto tranny lock up is something that's found in the PS9 but not the standard PM6. I was thinking the ECU for the auto RT model might be able to do this as well.
Not looking boost or anything, I know boost guys love E85 and all but my thought is keeping my fuel money local instead of going to parts of the world that well.... You get the idea, keep it local. Anyhow I think I might just go pick up a Y7 and put the mini-me on hold for a while. I can pick up a good Y7 diry cheap and run it on a PM6 for a while. The two timer should still let me run E85 with some tuning, hopefully without changing the pressure regulator or injectors and only changing the injector duty cycle.
this blue box was though...
no because only the A/T models i've seen at the yard had it. mine doesnt (and i have auto belts)
thats where mine is also
