super eta ecu swap??

[crazys]

I am puting an i head with a mild 272 cam in my super eta, now my question is what do i do ecu wise do i have to swap in a i motor ecu and will that require a lot of work or what do I do??

[MR 325]

If you're swapping to an i head, you'll want the i intake manifold, wiring harness, and ecu

Good luck

I think the sensors for the super ETA are all the same so you should be able to simply swap ECUs.

[mikeedler]

you need the harness. different connectors for the ecu "I think "if i remember right.

[crazys]

so how hard would it be to install it all

[e9nine]

It is a plug and play swap from a super eta ECU to an m20b25 ECU

[crazys]

so all I do is plug the new ecu where the old one was

Any benefit to using the "i" ecu on a stock super eta? At least I could chip it. Nobody seems to make a super eta chip!

[nando]

well on a stock motor your rev limit would be too high. I'm not sure other than that.

Not worth it, a pure waste of time. Either you start saving up now for a 2.7i (search, there's a ton of info on it) or just swap an m20b25 motor in.

completely worthless. your power is missing because your cam is crap. along with the crappy intake and crappier exhaust.

Nice post.:roll: Without proposing any solution, this post only displays a lack of understanding with regard to Super Eta characteristics.

FYI:

Super Etas have the same exhaust as the i models. Part #s are identical including the cat.

The head has double valve springs, too. The intake must not be too bad, otherwise Korman wouldn't use it on their 2.7l stroker motors. They ExtrudeHone it, but that doesn't change the length of the runners. I am aware that the cam is not optimal for power production, but Korman uses the stock cam in all their "clean air" engines. A more aggressive cam can cause cars to fail emissions tests. They use a 272 in their competition motors.

I figured that the worst issue was the fuel and spark maps, which are biased toward lean operation and wondered if maybe the different ecu might make a little bit of difference. I'm not looking for a big power increase, just a little better drivability and smoother acceleration...

The Super ETA has the "i" head and intake already. It has a different cam and the ETA bottom end with super ETA pistons.

FYI: super eta heads are basically "i" heads with SINGLE valve springs and eta cams. Stock, the super eta's 127hp happens at 4800rpm - if you're looking for more power, you won't get it with this cam. There is a considerable difference between "i" and eta intake manifolds.
You can't just install an "i" ECU on a stock super eta. It would run like crap because the two engines are tuned for completely different power curves.

so I am doin g the full icam swap with the i intake will the ecu just plug right into my old harness or will I have to modify the harness
