I know it's been over. But I do want to know if a stock TII ecu from a S4, maybe remapped would control a 13B-RE with the twins on non-sequential or if maybe putting on a S5 turbo would work? I would like to avoid a stand alone, at least for a while. I've heard that the stock ecu can handle the 13B-RE as it comes from Japan with sequential turbos, but not very well. I want to know if non-sequential or a S5 single would work?

Thanks,

Hey dude,
The S5 ecu should work , if using a S5 turbo on the engine. If you want to run the twin turbos then I think you may have to use the stock Cosmo 13B-RE ecu, N390 with the auto tranny it came with. If you're interested plz let me know as I have one for sale.

would a s4 ecu work with the s5 turbo on the RE since that is what most s4 guys swap to is the s5 turbo on the 13BT?


Thanks,

I also wonder, does any of the S4 TII parts swap over? If i was to change out the CAS and what ever other sensors are on the RE for S4 ones, would that maybe make it compatible with a S4 with S5 turbo?

I am looking to buy an engine for my 3rd S4 FC and i would like the larger ports that the RE comes with but the economical and streetable stock computer with maybe a Rtech7 chip and/or an ApexI SAFC II.

Thanks,
J

The motor doesn't drop in.
A stock Cosmo ECU is not going to work properly.
A stock Cosmo ECU remapped to get rid of all the stupid electronics error codes might work but not very efficiently.
A stand-alone EMS is highly recommended.
The Cosmo 13B-RE CAS is the same as all FC3S CAS.

It sounds like you're trying to do this on a budget.
I don't recommend going this route.
You're going to end up with a lot of car parts laying around.

Thanks. Nix that then.

Not to mention the PITA time yo would have with the two different TPS sensors.

If electrical wires scare you, yes.
Cosmo motors run the same TPS as the FD3S.
They have narrow-range and full-range TPS' built into one unit.
It's easy to wire them to mimic the S5 TPS.

so lets talk about a TII ecu. I read alot about that but i havent read on one actualy running correctly, its all been talk and i heard this and that. I would actualy like to know how you would go about making it run right? because that seems to be a big draw to these engines but i cant find any solid info on it.

thanks

I would never do it that way myself.
I prefer Haltech EMS ECU's in this application.

but if you where going to do it that way, how would you go about it?

Rx_treme

if you want to do it cheap to get it running just drop in a s5 ecu and harness.. theres only a few small things you need to change it over to make it work.

thats what i was wondering whatthey would be i know you need the run the turbo's non-seq but thats about it

RETed

With the stand-alone?
I'd go Haltech.

With the stock ECU?
I would never attempt one.

i was talking stock ecu, what challenges would there be by using the stock ecu

Back up.


I have a guy which bought a 10th AE and has a comso dropped in the car.

This guy is a COMPLETE rotary newb!!!! I mean NEWB!
I told this guy he was stupid for getting the engine but it's too late.
He has no money for a EMS and needs it running soon.

So The TPS has kept us stationary/in holding position using the stock S4 ECU.

We're going to need to use an S4 TPS since it's a S4 car and ecu and harness.
I checked the TB and it is a bigger port as well so there goes my idea of using a S4 TB

He said the injectors were 550's all around. Is that right???? If so I assume the stock RE turbo will kill the engine quick using an FC ECU/fuel map.

Any way. Back on topic.
The RE TPS is a narrow/wide TPS and is 4 a pin.
Is it possible to use on a S4?


Also second option/maybe
Run as S5 so the TPS won't be a problem. BUT you now have the interior harness S4/5 problem.

If it's not possible to run the RE TPS then I guess we'll have to work with a S5 harness.

RETed

Cosmo TPS is identical to the FD3S TPS.
It has a narrow-range and a full-range TPS built into it.
You can just wire the narrow-range TPS to keep the S4 ECU happy.

Yes, the Cosmo uses 4x550 fuel injectors, all high impedence.

Good luck trying to get it to run.
