4efe or 4afe box + 4efte in a Corolla E11?

@Jay I am looking for the Glanza V ep91 loom wiring diagrams to swap them with the extra Corolla wires. Same for the fuse box. I will need both Glanza GTI and Corolla E11 diagrams. Can you help me find them?

@Jay I have a simple question. how come the Toyota ECU that comes with the either 4efe or 4efte cannot be mapped?

Toyotas of this era have the data stored on ROM (Read Only Memory) which means you cannot write new data to the ECU. To get around this is an expensive and specialized task, most often a daughterboard is added to the ECU containing the new tune.

That's how the JDM aftermarket ECU's have been built, JAM, TOMS, Mines, Sard, etc

At a guess I'd say you are looking the wrong engine loom.

Get a look at your engine ECU and grab the part number from it. More importantly check how many connectors are on it - it'll be either 2 plug or 3 plug.

*Bonus tip. Swap the 4efe oil pan with the 4efte so you have better clearance for the exhaust.

You would be using the 4EFTE sump anyway as you need the turbo oil return that's built into the front of it.

Ask him for a few pics of the setup showing PAS pump, oil filter, turbo and downpipe if he can offer them. These are all grey areas for you and it might help you understand what is needed.

I didn’t express myself properly. What I mean is that I am swapping the engine with the 4EFTE with complete loom, ECU and because they are getting the engine out from a half cut car, I will be able to get the Starlet fuse box with uncut wires.
As I will have to adapt the new fuse box to my Corolla, I will need diagrams. Same for the extra loom wires and probably sensors? What I’m trying to do is prepare the job ising the diagrams.
My 1998 4efe with electronic ignition might have a ECU with 2 connectors. But I guess that doesn’t matter anymore because I am switching them. I will get the engine running and when I will have the budget I will add my Corolla ignition pack and inlet together with the fuel pump and the piggyback to be tuned. I am not able to do the whole job together.

When doing the loom splice our local guru always said that matching the number of plugs on both looms made things a lot easier. In your case that could affect the man hours and thus the ££ involved.

Anyhow, I've attached the pinouts for the 4EFTE, I have no reference for the Corolla 4EFE unfortunately.

Now I could be wrong but I don't see the E11 4EFE on that page? Plenty of other random diagrams as I scroll down but still don't see it.

I opened a 89661-1A080 Corolla 4EFE ECU yesterday (I'm guessing it'll be close to your one) to compare it to a 4EFTE ECU (part number 89661-10100).

Unfortunately the Corolla ECU does not have the pins marked out on the circuit board like the Starlet versions do. Physically the boards are worlds apart. Bear in mind one wrong pin and you can damage something.

Can I ask what components are included with the 4EFTE? There are a few things you should ask for to make the swap easier.

You can see the pinouts listed on the board in the last pic. The Corolla ECU doesn't seem to have them.

Jay just when you've that open give it a good look over for any leaky capacitors, them big black 1s are prone on the celicas to fail giving allsorts off bother

It'a ep91 with 88k Km. It will be detached from a half cut Starlet. I am getting the complete engine with mounts, turbo, top mount intercooler, manifold, inlet, loom with ECU, wires and uncut fuse box and map sensor.

What else should I ask for to make the swap easier?

Things you'd be best off asking for from that Glanza:

-Ignitor & coil (your car has a different ignition system)
-PAS pipework (just in case the Corolla pipes don't reach the 4efte power steering pump position)
-They will probably leave the downpipe on the engine but ask anyway (it will make fabricating the exhaust a bit easier)

The bonus of inserting a 4EFTE is that a lot of the mechanical concerns are taken care of. The electrical stuff I don't know a huge amount about so can't comment too much.

Make sure you set aside a budget for freshening up the 4EFTE after you get it running - at over 20 years old it'll be due a few bits and pieces.

Definitely what parts usually necessitate replacement? I will not rettificate the engine tho. It has to be good. They’ll give me compression data.

Would allow for :

-obvious oil filter and spark plugs
-timing belt and waterpump (long overdue at 20 years)
-thermostat (they start to stick over time and can cause overheating)
-clutch (bound to be worn)
-any gaskets or seals that show signs of leak/weep (depending on what you find when the engine is in and running)

A lot of these are easier to access whilst the engine is out of the vehicle, best approach is to hope for the best and prepare for the worst :)

I'm not sure of the fuel pump specification on the Corolla, your tuner should be able to advise if more fuel is needed. I've always swapped the 4EFTE pump into the turbo conversions I've done here just for safety.

One fueling point to be aware of is that the Japanese 4EFTE is expecting high-octane fuel so you should run it where possible on the best super unleaded that you can access. I've run mine on Maxol super for years.

I was looking for the replacement parts and there are many timing belts, gasket replacement kits on the market. Do you guys suggest a few just to be sure I don’t buy crap?

Good suggestion. Problem is that here in Italy high quality octane gasoline is rare. We have V-Power Shell but hard to find.
