ECU idea

[ricerrx7]

I've been thinking lately. Everyone complains that our ECU's are too dificult to crack and that the only tuning solutions are things like the safc and unichip. What makes our ECU so special? It just takes in and puts out signals. Couldn't we possibly take an ECU from an ecotec (or any other four cylinder car) that has tuning capabilities, figure out the wiring, then tune it to read our inputs and control our outputs? Then we would have full tuning capabilities, and could get an ECU cheap from a junkyard. What are your thoughts on this?

if you can make it work, that would be awesome

i know for my car, i can buy a 25$ jumper kit solder it in or pay someone like 75$ to do it, and the stock ecu will be ready for hondata, crome, neptune, uberdata. this is the route i will be going in spring when my turbo kit is finished

if someone stateside can figure it out, they would be legendary

what you don't realize is alot of modern computers are like that. not just the elantras. Modern ecus are all harder to crack to keep the engine "safe" and to keep it within operating parameters.

Why do you think people pay so much for hondata and stuff like that? its just a piggyback but it ACTUALLY works. The ecu just wants to continue doing what its programed to do and keep the maps and ignition and everything within its own specs. when it starts to see things outside of that it fights it and makes it go back.
As cars get more and more advanced the tuner is going to have to rise up as well. Then again there always is the better option of using a standalone, which is what i perfer.

No computer is uncrackable. It's just that not enough people have the want/ability to crack the elantra's computer. But with more popular performance cars (camaros for example) you can change the vehicles stock computer so it does what you want it to do.
Cypher what you are saying is correct, except that with other cars people have figured out how to change the values that the computer is looking for. If we could find an ECU that people have already cracked and know how to tune, then why couldn't we wire it into the elantra and have complete tuning capabilities?

[Cypher]

camaros differ because they are designed to make more power BUT i garuntee if you try to push out ALOT of horsepower on the stock computer it won't work. theres way too many variables to be comparing cars, especially a car with a big V8 to a car with a motor almost a 1/3 of its size.

different computers have different parameters and values programed into them. i wouldn't want to risk my motor with an unknown ecu. there is a way to crack it. its called a standalone its a tried and true method that anyone who wants to make power safely will use.

What about a megasquirt ECU?

I've never really read up on these, but it could be a possibility.

[Cypher]

thats a standalone, like i've been saying.

[05xd]

Megasquirt is a full standalone computer that you have to build yourself and input all the maps for fuel,ing timing and all that good stuff.My buddy has one on his turbo'ed accent.He said he will never do it again.Way too many variables you have to compensate for.If you have patience and alot of downtime for building and tuning,go for it.ONLY if you know what you are doin

[Cypher]

all standalone are that way. you must input all the variables for fuel pump voltage, map voltage, every little thing must be inputted into it but once its done you have limitless power.

[PSUsouthpaw]

So, perhaps we can find someone smart enough to know all these things to set one up for us.

[Cypher]

most hyundai tuners aren't that dedicated as to learn all that and do it. a MS is alot of work and takes quite a bit to learn well.

[KeWLKaT]

Well since ohio_beta has a beta2, im sure that if he realeases the info about the inputs, everything will be well :)

[06elantra]

them megasquirt are really good standalones... the MSII are even better im told (i know a lot of peopel on some Ford Forums that run them - and swear by them)

if ya can crack the stock ecu - which no doubt is possible, once you know the trick im sure, then power can surely be made.

if the stock ECU can be cracked, IMO (<--- note MY opinion) then you can get a power putting out ecu, that will still have all that extra 'standard' stuff to help your car run. hmm that didnt come out to well.. but i know what i ment at least...

[Jonny666]

I think the problem is we are attacking the ecu from the wrong direction..... the new ecu's are too smart to be overridden..... but it may be possible to make them override the stock settings to your advantage.

[TSmooth8403]

maybe this has been answered but what does shark racing and kdm use to reflash ecus?

[Cypher]

^not a damn clue.another way "around" the stock injectors is with supplementary (sp?) injectors such as what alpine does.

[PSUsouthpaw]

But do we really need more fuel, or is this more of an issue of ignition and spark timing?

[Jonny666]

we dont need more fuel for the most part. just fuel and spark control. the sup. injectors work fine for the turbo guys but its just more unneeded fuel for the N/A guys. I think its going to work out to be a combination of fuel pressure control for large adjustments with light air fuel tuning and some kind of spark miracle.
