just looked at the AEM web site for a ems, and they only have stuff 4 cars that are manual . anyone no were to find ecu upgrades for an automatic? thx.

The AEM EMS is fully compatible with automatic transmissions. You will probably need a harness for your auto ecu however because there is one extra plug on the auto ecu. I know AEM has a few universal harnesses, so that may be the one you need to use if they do not have a harness for your specific application.

just get an obd2a-obd1 conversion harness and chipped obd1 ecu, its much cheaper than the AEM EMS but can do just about anything the AEM can.

It's not that easy man. For manual, yes, but not for automatic. If you want to run an auto tranny off a chipped ecu you have to get an automatic obd2-obd1 conversion harness. I know of one guy who sells them, and they are not that cheap. I think it was $250 shipped to Canada.
And it doesn't stop there. The obd2 auto tranny is not compatible with an auto obd1 ecu, so you have to swap out for an auto obd1 tranny.
Factor in cost for parts and labour, and you might as well get the AEM unit, or just swap to manual if your going to change trannies anyways.
The best option for automatic trannies on a budget is the afc hack, or emanage. Depending on your needs, this may be enough, but they do offer substantially less tuning capability then the a full standalone.

ya, thats brutal.....$250 just for the harness is rediculous. Not to mention the performance lost with an auto tranny.
But the afc hack is a garbage method of tuning (i used to have a vafc2, now i use crome) especially compared to a standalone or a custom chip.
I didn't know you can't use an obd2 auto tranny with an obd1 ecu....why is that?
I would suggest using a manual tranny if you are serious about performance. B/c greddys emanage/vafcs are crap. And theres nothing like banging through the gears on a 5spd.

You cant use an obd2 tranny with an obd1 ecu because the transmission control unit for the obd2 is in the ecu, as opposed to obd1 where the tcu is in the tranny itself.
So when you run an obd2 tranny that relies on signals from the ecu, and your using an ecu that doesnt send signals, your transmission won't be able to shift.
One way around this I suppose would be to integrate the tcu into the obd1 ecu, but I'm sure you could finish 10 manual swaps before you figured that mess out.

awsome info yall, ya i would love to go manual,,something to think about 4 sure,best to gather all the prts first,,trannys no prob but then some of the others ,,,hmmmm pedals,clutch resivoir? for the fluid? is it a tough swap? i got some buddies bac down t.o way(george town that could give me a hand ,,lol id have to drive 15 hours thou,,lol thx

antrmo

well i called aem direc in cli. they said no such thing 4 an auto so lost cause i guess

antrmo

any other ideas,besides smart azz coments .lol

What are your plans for the car? If it's high horsepower then an auto to manual conversion might be something you should consider. I just did the swap and its not THAT hard. It did take me 4 weeks to finish though, but mind you I had no power tools, and the engine was in the car. Plus I didn't have much time to work on it.

If you have access to power tools and an engine hoist the job will be much much easier, but its not impossible to do without that stuff.
Normally its about a 10 hour job, so if your gonna get friends to help, do it on a weekend. Oh and make sure your friends know what they are doing. I had a friend help and all he did was break my lower balljoints. That pretty much set me back a week.

As for parts, I did the swap on an EK, and I had to get:
-clutch pedal
-master cylinder
-slave cylinder
-clutch lines
-manual ecu
-manual intake manifold
-manual iacv plug
-manual starter
-manual distributor
-transmission
-flywheel
-clutch and pressure plate
-shift linkage

I think thats about it.

If high engine output isn't in your future, and all you want is some tuning capability with your auto tranny, then e-manage should suffice. There are guys out there running emanage with turbo's at 10psi so if you aren't planning for anything crazy I think it would be enough.
