BEAMS 3SGE Redtop or 4AGE Redtop?
Should I really be this confused, or is it due to a lack of information?

if you use the automatic ecu/wiring, then you will constantly have a CEL on, but it will still run/work just fine

From the mouth of Tacoma's Toyota god (Rix86) You will need to change the wiring harness over. You can keep the computer in the auto though but I'd switch it over just in case.

LOL you can even ask Rix86 to help you do the swap. Umm but oh yea I forget he hates working on our cars least the turbo models. But I would listen to Rick and what he has to say. If it's 4age related he knows his stuff.

| You need to use the ecu and wiring harness for that motor for your swap. If you don't the ecu and motor/tranny will not work properly. It's important every time a swap is done that a matching ecu and wiring harness are used for that motor. I'm an auto tech student. Hope this helps. |

wow.... everyone just went right past my factual post and put up their own garbage....
the automatic ecu will run the engine fine if there is a manual transmission attached. however, it will throw a check engine light constantly because it will think there is a problem with the automatic transmission (which there is... it's not there).
yes, rick knows his stuff.. but he obviously doesn't know this.
i have seen this done on an even newer toyota..... I highly doubt any of you know a guy named shawn who used to have an ae102 (and at the time was a pioneer with it..... including many 7afe tricks that other corolla owners don't think will work..... he was the one who taught me how to modify the ecu because him and Tim, another oldschool guy in Tacoma that I'm sure none of you know).... he had an ae102 auto... swapped in the manual, made sure it ran fine, then modified the ecu for a higher rev limiter.
but... if you decide to not think outside of the box and follow all the other lemmings then you could easily obtain a full manual harness for cheap.... and if you really want to go outside of the box, then you can go with an upgraded ecu and actually learn something

Well thanks I love being insulted and belittled at the same time. Most of us don't have the time or money or knowledge to start playing with a 22 yr old computer. So we'll just be lemmings and do whats in our knowledge and budget to get it to run right then mess with the tuning stuff. But whatever insult me, my friend, and the rest of us just trying to help someone just so you can feel superior. thank you.

It was more of an insult that I posted a factual statement that it would work... everyone ignored what I had said and put up their own incorrect statement....
You say you don't have the time, money, or knowledge....
The amount of time you have to work on your car really doesn't matter. As long as you have some sort of bucket (at the very least) to move you from point a to point b... you should be able to work on your projects when you have the time. When I first got into mr2's I was in college full time and had a full time job. The time issue is just whether or not you can withstand taking a long time (little bit here and there) to put your car together.
it really doesn't take that much money to work on these cars. I built an ae101 4agze with e51 trans running on megasquirt for about $1500, including the cost of the vehicle. I'm currently building an ae101 4agze converted n/a converting to turbo, running on megasquirt and putting a new transmission into it at the same time... in the end will end up costing less than $1500 including the cost of the vehicle. My wifes 86 (which is a DD) has some aftermarket parts, an ae86 engine and is on it's 2nd trans... we have less than $1,000 into it including the cost of the car.
Knowledge..... everyone starts somewhere. I personally had zero interest in cars before I was 16 and didn't even start doing actual work to them until I was about 19 or so. I'm only 24 and I have a lot more knowledge than tons of mechanics. It all depends on your outlook to learning and, as I said before, looking outside of the box. Perfect example of this was my first supercharged car. I bought the engine knowing it had a cut harness -- to save money. I was told by a friend of mine that I should use megasquirt. (At the time, the V2.2 was the newest & greatest out there. DIYautotune didn't exist.... there wasn't a whole lot of support for these yet). So, not knowing anything about soldering or whatnot I bought a kit, put it together, wired it up, and it started the first time. All it takes is the want to learn it.
The only thing, in my mind, that you really NEED to have to work on a car is a good friend you can call if you get stuck with something because you don't know how to do it. I know you do, because you talk to Rick.

Well as a side comment, after talking to Rick about the messing with the stock computer to allow a higher rev limit, he highly recommended avoiding that because it messes with everything else and at that point a aftermarket ECU or fuel system meant to be tuned would be highly more advisable. I've got about $1350 into my MR2 including car costs but I'm using very very few old parts and all the important parts, bearings, pistons, rings, gaskets, alt, are all from toyota. Only thing aftermarket so far is adj. cam gears(made with the OEM outer ring) and the clutch. So anyways, yes alot of tricks will "work" but not necessarily at optimum levels or really appropriate for the intended use. Thats why I get mad when people refer to others using a way that will for sure work the way they want it and keep the cost low, as lemmings or followers.

rick is only partially correct about the ecu..... he either doesn't completely understand what happens (which i doubt) or he didn't go into full detail as to what happens...
my ae92 is the PERFECT example of the ecu mod. When I first did the swap, back about 4 years ago or so, this mod was pretty much unheard of and there were a few people that knew of it and how it affected the ecu. I took the car to a corolla meet where over 1/2 of those that showed up were long-time ae86 guys. There was pretty much hell raised about my car and about 9/10 of the ae86 guys were angry that I had done it (yes, actually upset) and told me so. They told me it wouldn't work, the engine wouldn't run right, the engine wouldn't last like this, etc etc etc.....
Same day I outran just about all of the ae86's.... and later when I went and dyno'd it I put down respectable numbers considering the condition of the engine (and some other problems that hadn't been smoothed out yet).
There is 1 problem that I deal with every now and then with the smallport running on the 4afe map electronics (and modified ecu). However, that problem is a cooling of one of th electronics causing them to fail (ignitor) and has nothing to do with the effect the electronics have on the engine.
the ecu originally had a 6700 rpm limit and now runs the 4age up to 7800 with no problems. the car still pulls harder than a stock bigport and hasn't shown any signs of excessive wear.
So, when people say that doing the mod causes problems.... they're not correct. My car is the perfect example, and I still get people telling me it won't work. I get (depending on how fast I am driving... faster yields much better results) at least 30mpg in the car as well and have exceeded 40mpg.
To recap, this mod has:
-not caused excessive problems
-been reliable
-not caused failure of other sensors
-dyno proven performance
-long term reliability
-good gas mileage is kept
