OK first I would like to know who actually has a stand alone ECU in ther personal cars. I also belive that is the rev cut for the limiter, but not be able to raise it with the Emange ( I could be mistaken on that, I dont have any first hand knowledge with it). The reason I dont want to ggo to a full standalone at this point, is because I will be working witha 7age swap, so all that will change majorally from stock is the headside ( cams,sensors, ect) with a N/A build, olny lookinh to get somewere from 180hp to 200hp and the crank. So why should I invest that much in the ECU at that point , if I am not going forced induction and looking to get outragous numbers, all I would need to ajust is the fuel because spark is fairly set mechinical, and TVIS would most likely be from a Rpm switch. Besides my other option would be to use a chipped Honda ECU, and then convet the sensors and ignition system from that point.

Sorry but no that is not what I am talking about, I do not need a two-step rev limiter. I need a way to raise the rev limiter beyond the stock presest to around 8,000 rpm. So far what I have been thinking there is no piggyback that can do that. Does any one know about intalling a new crystal in the ecu in order to raise the ecu revlimiter? My guess that that that would mess with the stock fuel maps, but that should not be a problem with a good programable piggyback.

Getting back on subject, I dont think there is any piggy back that can raise a rev limiter, if there if please show me.

Hello, I was wondering if any one knows away to raise the rev limiter? I am looking possibly to raise it to 8,000 RPM. I have the 7AFE ecu. I am currently under way with a 7age project, I need i way to raise the rpms, other wise I have to complete my Honda ecu in a Toyota. I heard something about crystals or something, but I'm not sure what that is all about.

No offense but no one really never answered my question, I all ready know its a C52 trans and it should fit, but did you provide any other information? I didnt think so.

OK so the AE 92 Corolla GT-S comes with the C52 trans. Now in theory the C52 trans from the AE92 should bolt up to a AT200 trans with no shift cable problems/wiring/mounts. Now if any one has any actuall information of proof of this can you please replay.

Well seeing that no one can help with this question, I guess i will try a diffrent one. Does any one have anytpe of experince with using a Honda ECU for a Toyota

THis could be considered spam but I was searching on the site and could find little usable information.
I am currently building a 7age motor, ( Yes I know im sure someone is going to tell me " Your wasting your money go boost, ect" but im looking for a tunned daily driver/autocross car im not looking for tons of power and drag race, I'm looking for 180hp at the crank ). I will be running a compression ratio of about 11.7ish as of now. I was wondering if any one has real experience or input on a standalone ECU setup? I have heard MegaSquirt is the way to go, but that about it. I havent been able to find any details on install details, problems, wiring ect? Yes I am aware Mega Squirt comes with instructions.

well i pla on dropping some cash anyways mainly in part i can do all the rest my self the onlyt thing i would be paying for is machining work , i would have the head checked out, valves ect depending on what it would need, a slight polish, new cam(s), ajustable cam gears, for the block, slight bore, high compression pistions, balanced crank, still looking for a place for new conrods

new injectors, greddy emange, and the other things hear and there, so like i said i mainly would be paying for parts and machine work, i got pretty much every thing else labor wise covered. like I said i am also playing with the idea of 7agze, but idk about the oil cooler yet, i havent looked into that much yet but im guessing it would be similar to a turbo set up.

Thats why if you would use the same block of the 7afe u wouldnt have to worry about tranny or shift linakge problems just the intake and exhaust, and maybe a pully or 2

I would be willing to do a z swap, all i would have to do is run a oil coller then. I have a friend who has a 86 gts coroola he might be taking the engine out so i might be able to get that off of him. Im not going to lie I am kinda stuck on the idea of doing a 7age not that many ppl have it done, again im only looking to get around 180 hp at the crank if im going NA, or actually 100HP per Liter.

OK so heres the deal I just got a 95 ST , I dont have to worrk about emissions were I live Im still decideing what do do with my car. I want to make only around 180hp at the crank, but im looking to have as little custom fab work and also trying to stay away from jdm parts that would be hard to get( possiblilydo a 7age na bulid?). I would most likely be dropping the trans and engine at the same time( I have to to a rebulid on the trans). ANY info or imput would be cool, especially aftermarket or piggy back ecu help.

Why would the ECU think it has lower compression? That makes no sense if its a 7age the head cc would stil be around the same if anything it would raise, and besides i would either have the 4age pistons or the high compression 4age pistons.

I most likely would end up using the 16V bigport, I will be doing a engine rebuild with proformance parts. Liek i said im still working on the ecu aspect. Why wouldnt the stock ecu work, I mean the head will have have a effect on the ecu, but the stock ecu might be able to handle the engine inputs to a degree. The ecu can do thinks such as spark advance and such as aposed to fully custom ecu that is based on fixed data rather that liev data. This is getting of topic now, like I said if any one actually have information or experiance with the 7afe ecu. So can you not tell me "get the engine one or fully custom, ect" I'm just trying to get a guide line of actuall use or data. Any help would be great on the or actuall after market ecu setup, rather then tell me just to get one.

OK I plan on doing a 7age head swap, im only looking to get at least 180hp at the crank so it should be to bad but, I was wondering how the 7afe ecu is, I heard rumors of desoldering crystals to raise the rev limter, but my main concern is the fact that the ecu can handel the inputs, and still not sure about my sensor wiring yet. This is in theory right now, im still waiting on the gead and figured i should work on my ecu problems first and play with that before the swap.

I'd be boring it out to 82.0 MM. Im not going to do the 20V because im actually trying to be able to get parts locally from the dealer rather than having to get every thing from a 3rd pary or off the internet. Besides then if I would do the 20V then i would have to more fabrication work.

OK please dont spam me but this might have been asked before and I was looking in the site for the answers but not close to what I need. I will be building a 7A-GE motor to be put into a 1995 ST, so i dont have to worry abouut OB2. The head is going to be polished, new valves, springs, ect. The Block is going to be sleaved and bored slightly, high compression 4AGE pistions, forged rods, balanced crank. So basically im going for around 200 to 240 NA horsepower. Im still working aout the ecu issuse because I might be doing ITB's to so if got any suggestion that would be cool. But my real question is whould would be a good upgraded trans that is USDM and has little to no mods. I am trying to keep it somewhat USA OEM in regards to parts fabrication. I'm not sure but I'm can find what trans in in now( o yeah 5 speed speeds of course), but I have heard the C52 trans bolt pretty much right up. Any and all help would be cool.
