96 ae102 BT20v ecu

[Ae102Zzw30]

Ok. So it's been a long time waiting I'm finally ready to do a 20v swap. I'm going to purchase a full clip. So hopefully that will help me take care of alot o parts I'm going to have to replace. I'm going to be sending the harness out to dr tweak now I have to decide what I am going to do for engine management. I have emissions for a Few more years with this car in my state and want to be able to pass. For me to pass ill have to have a computer that will run obd2 from what I gather none of the 4age ecu were obd2. So my question is does anyone know of a good solution to this? I don't think they can remap and chip the 7afe ecu. So does that mean I need a after market piggyback like an emanage or unichip or mega squirt? Can I run one of those piggybacks in parallel with the stock ecu Or would It be smarter to try and run it off a Honda ecu? Is there any full standalone I could pass emissions with? Any advice tips or anything for the swap will be greatly appreciated.

I don't think we can help you much unless we know what car you have, what state you live in and what regulations you are trying to pass.
The 20 valves are illegal in the US so the more strict your areas laws are the more likely you are to be found out. For example if you live in California or some of the stricter eastern states that spend some time under the hood there is nothing you can do to give you good odds of getting by legitimately.
On the other hand many other areas just require you pass the sniffer and maybe inspect for gas cap, charcoal canister and a couple other things. In which case getting by should be easy. Some check for a CEL but as long as that works you are good.
Since you say you need OBD2 I can only assume your car is newer and runs OBD2. In which case any 4AGE will stand out as that much less legal since as you said none were made with OBD2.

Sorry I thought it might be picked up on from the title. The car is a 1996 Toyota corolla DX with the 7afe and a auto tranny. I am going to be doing either a blacktop or silvertop swap. I live in Connecticut. Are emissions are strict but nothing close to California's. they simply look for a cat hook up a sniffer on the tail pipe. Then they plug into the obd access port to do what they call an obd test. This is what I am worried about. I have some friends I can speak with about getting around it but I would rather just spend a small extra investment to have the car running right. Also the stock ecu for a silvertop or blacktop should be tuned to require at least the 97-101 octane that is available outside of America. Anyways this is the description of the obd test. "The inspector will connect a communication cable from the emissions testing equipment to your vehicle’s Diagnostic Link Connector or DLC. Through the cable, the emissions testing equipment will request specific communication protocols from your vehicle, allowing the testing equipment to verify whether or not your vehicle emissions control system is in compliance. Information is retrieved from your vehicle; nothing is uploaded or installed on your vehicle."

Also I'm not worried about the motor sticking out to an inspector they couldn't give a crap around here as long as its easy to hook up and it says everything is good they pass you most of the time they don't bother looking for a cat or even checking the gas cap. You can have a mean exhaust leak with barely anything coming out the tailpipe as log as the cel is off u usually pass

Lol totally wasn't paying attention to the ae102 in the title.

You want more power, you want OBD2.
20 valves aren't all they are cracked up to be, especially any more.
If I was you I would start looking at a 1ZZ or 2zz.
The cost of the swap will be a little more but in the end you will have everything you are looking for completely legal in every way and another 20 hp.
By the time you figure out a way to cheat the system your cost and trouble might just exceed that of a XZZ.

When I did my turbo 20v in my AW11 I went 20v just because the 2ZZ alone would have cost me another $3k. If I were doing the same swap now I would not look twice at 20 valves.

[Ae102Zzw30]

Well I guess that would also be a very valid reason to pull my 1zz out of my spyder with 45k on it and do a much Simpler 2zz swap on that. I would have the best of both worlds. Has anyone gone this route at all? I know the chassis doesn't differ much from the ae101 to 111 so I'm guessing the motor and transmission mounts would probably fit? Guess I might have to start a new thread new sub forum lol?

[yoshimitsuspeed]

Sounds like a pretty good idea to me. If you ever want more power you could throw a turbo on the 1ZZ or at that point a swap to 2ZZ should be pretty easy.
I have done some research on a ZZ into an AW11 and overall it appears to be one of the easier non 4A swaps out there. I doubt yours would be any harder.
