Swapping ECU's?

[RacerFreakXXX]

Has anyone considered using a different ecu and just retuning it for the Yaris? Idk if it is possible for a street legal car but I have heard of people using other ECU's when they swap in a different engine or even when you want to use Hondata on your s2k, and using a RSX-S ECU.

What applies to a Honda does not apply to a Toyota in reference to the ECU. Its a good idea but unfortunately the ECU in our car only comes in our car. It not interchangable like some Honda/Acura ECU. This is the future: http://www.dezod.com/pd_apr.cfm

But we need something more plug-and-play...

IMO this is more than most people can handle. I dont think people here are going to have the knowledge to put together an ECU to run there car. Its an option but I think it down low on the totem pole.

The unit Im working on is as PnP as it gets. Not one solder, crimp, tap is necessary.

I totally agree. The current iteration of the DIYEFI is quite basic and only meant for super gurus... But this could be the basis for totally customized ECUs down the road... It's all a question of time really...

The problem is that standalones are becoming harder to PnP with newer ECUs. My Miata is simple, and for less than $500 I can buy a kit to assemble a fully programmable replacement for the stock ECU (Megasquirt DIYPNP). That's because the ECU runs the engine, and that's about it. The Yaris runs all sorts of shit through the ECU that's hard to replicate. Air bags, emissions testing, A/C, cruise control, immobilizer, etc.

You could build a unit that would control the stock timing and fuel without too much difficulty, but half the car still wouldn't work. That's why reflashes and interceptors are becoming more and more popular; it's hard to run anything else on a modern car.

I was thinking maybe swapping for a celica ecu, or mr2, or xb/xa... something of that nature. In all honesty I'm surprised no one has come out with anything for the yaris. I see at least 3 to 4 different yaris a day. It's also a perfect tuner car for a young kid who can't afford a 22k civic si, god only knows why they have become so expensive. Maybe one day someone will have something, lol.

In the case of the Corolla, you could swap ECUs with the Celica GT 1ZZ-FE. It has a slightly higher rev limit, and makes 5 more hp than the Corolla.

But all cars with the 1NZ-FE make the same power, so there'd be no difference.

In the case of Honda, they all have a K series motors, so the ECUs are compatible with one another.

I have seen someone swap a Toyota ECU into a Honda, but I think they used a Toyota engine as well, it was a weird swap on honda-tech.

But that dezod thing is not the future. I don't know anyone in their right mind who would shell out $1800 for something like that vs. an excellent standalone system which would even be cheaper. Just because it requires wiring, doesn't mean its impossible to do.

I could see the use for something like that on a more expensive/exotic car, but nothing like a scion or a toyota or honda

it depends what you want. If you don't want a straight on race car, having the ability to have the stock ecu still available is rather nice.

If you don't want a straight on race car

Thats when you just get a Greddy e-manage blue, that has already been proven to work.

Thats all that device really is is just an interceptor as well or so it seems.

I dunno, I just think it is silly, I can see spending money where money is needed. IE: name brand turbos, meth kits with failsafes, etc etc, but not something like overpriced piggybacks or .... backpurging piping when welding

Give us an example of a "excellent standalone system which would even be cheaper"

Everyday more & more Im coming to realize that this community will never grow. Im getting tired of people commenting negatively about products that they have no experience with. I dont understand why people think by commenting " don't know anyone in their right mind who would shell out $1800 for something like that" helps this community in any way shape or form.

There is a reason that Micro Image is our only vendor. And its comments like that. Why would anyone that has a business make products for us if every time someone says " it to expensive" "thats a waste of $$$" " it doesn't work" blah blah blah.

I'm glad someone said something.

Thx "Blu", Iv said it before & Ill keep on saying it.

I have everything in my shop/home to tune every brand of car short of a dyno. I have been doing this for a few years as just a side hobby because it is fun to me.

So if you are trying to ridicule me it will not work. It would be like me going into your thread and commenting on your turbo project and stating the obvious.

I am not going to have a who's dick is bigger than who's contest, but there are plenty of affordable management systems around. Theres Wolf, Haltech, Perfect Power to name just some ones that are under $1800, I am not talking about some $3000 Motec system.

You always think I am trying to prove you wrong, but I am not, I am just stating that if someone wanted to go out ad buy a piggyback system, they can get away with spending $150 on ebay for a blue, another $100 for some cables and whatnot for it, get someone to wire it for another $100, and then tune for like $300. $650 in total. Whereas you would need to spend $1800 on that unit, and then another $300 on top for them to tune it.

You make me sad cdydyjd
I am not Tamago
Don't think this is a special writeup, I'm peterpooping in the bathroom right now on YW


PS: The only reason that MI is the only vendor is because Garm monopolized the Yaris market, it's a smart move, and if that isn't clear to see then I do not know what is. Unless you come out with something major and custom and cool that you refuse to sell to Garm, then there will be more vendors.

i wish i have gotten those rates!

WTF? Tuned to get it's max power, since it has a conservative tune; but tuned to work properly? WTF?
