Automatic RT4wd/ OBD1 compatibility question

I can't seem to find this topic covered, I searched first, really I did!
My question/topic of discussion: Is there any reason why the automatic transmission in my '91 RT won't work with a d16z6? I don't know how much of the tranny is electronically controlled, whether the extra RPMs will confuse it, etc. Will it work or no?
And, do I need an auto trans ecu in obd1?

i thought i should share my observation and maybe it will help.
wagon.....................................4ever...............
For the life of me I cannot remember the ECU setup he was running. I think he was running a piggy back with OE ECU. Maybe it was a Z6 ECU. You might dig up his thread. At least it's a place to start.
Good luck!
Think it's worth the obd1 conversion, or just keep the a6?
real science...?
But his is a manual tranny.
I want a Z6 myself. I don't know that I'm gonna have the money to do it the right way, so I may just do a replacement A6 or DOHC ZC for this year.
Where!?
Now it's in the back of my wagon. I actually paid $425 to include a complete rebuild kit, a spare head and intake manifold, and distributor.
This particular engine does have the intermediate shaft mounting holes drilled and tapped
We do have a local JDM distributor though. So that's the route I'll likely go.
No idea on the ECU sorry, but i very much doubt the ECU has any hold over the box apart from lockup.
I'll answer what I can. First, RPM's will not "confuse it". I get what you're trying to ask and I know enough about engine management to tell you that it's not a problem. Second, yes, OBD1 needs an auto specific ECU and a separate TCM.
The OBD1 automatics are partially electronically controlled. 96+ are fully electronic. I completely forgot everything I knew about the earlier autos except that they were stronger and better than later generations which were made to slip more for driver comfort.
Contrary to popular opinion on forums, Honda automatics are great. What limits them performance-wise is that they have four gears vs the standard five, and overall the long gearing just kills acceleration on our low displacement, high RPM engines when compared to a VTEC manual trans.
Yeah, I always wondered why nobody "built" their automatic to handle a whole lot of power. I wonder how much power a stock auto could take.
I guess what I meant about the "extra RPMs" is that the transmission shifts well before VTEC would engage (I think?). Did the newer, EC trannies hold shifts longer?
If you have the throttle all the way down it will go all the way to red line.
My friend had a auto 89 RT4WD turbo daily driver. It made close to 200 whp. It warped the head and then he sold it to me and I parted it out. But the auto held just fine.
What's to build? TCI makes a high stall converter and upgraded clutch packs. Most likely discontinued. I agree that there's no reason to use a Honda auto for a race-only application. But if it's a Toyota Supra then that's something else.

hi-lo gearing...
: )))
you can only kill me once...stop it
