Programming the ECU of 4E-FE engine...

Hi people...
My engine is a 4E-FE with only 88hp... but I heard that the japanese version has almost 100hp... and that the difference is only the ECU... how can I can I copy the map of the japanese ECU to mine?

thank u!!

I'm afraid you cannot.

Only way is to source an ECU from a japanese car. Bear in mind that the japanese ECU will be tuned more agressively to suit their local fuel which is of a much higher octane rating than many other parts of the world. It will no doubt run fine on 91 octane, but higher is recommended.

How many plugs does your existing ECU have going into it?

I dont know yet..
I just know that the ECU has an eeprom... I guess that I have to disconnect the eeprom, reset it and insert a new map.. then connect the eeprom again in the board... shame that its not placed in a socket... it would be easier.I think its just that... correct me if I am wrong... well maybe it would be easier to buy the japanese ECU really.. :confused:

thank you very much! :)
But I wonder... wich are the specs of the Glanza's 4E-FE?
And I have to check the plugs of my ECU...

the 100bhp jap 4efe is the GI isnt it.

which has other things than just the ecu surely, 30bhp from just an ecu on a na? dont think so

either way, still alot for an na, especially a 1.3


100hp is too much for an NA?check the suzuki swift gti for example... its a NA 1300 with 100hp...
in europe the horse power of the 4E-FE is less because of the CO2 emissions...
that´s what I read on the net...

doesnt the 100bhp fte has different ecu, injectors, inlet manifold ?

"The first generation of 4E engines found in the Starlet GI, Soleil and Corolla models were produced from 1989 until 1996. The engine found in these two models produced 99 bhp (74 kW) @ 6600 rpm and 86 ft·lbf (117 N·m) @ 5200 rpm. this engine had more in common with the 4E-FTE, sharing the same throttle body, and slightly larger fuel injectors.
The 2nd Generation of the 4E-FE was introduced in 1996 producing less peak power: 88 bhp (66 kW) @ 5500 rpm, but with a slight increase in peak torque 87 ft·lbf (118 N·m) at 4400 rpm. The 2nd generation of the 4E-FE was essentially the same engine as the first but the intake and exhaust manifolds were changed along with a slight alteration of the ECU to reduce exhaust emissions."

the 100 bhp 4E-FE has a different inlet manifold then the 88 (or 75 bhp) inlet manifold. That 100 bhp manifold gave my 75 bhp 4E-FE 12 extra horsepower (on the crank, not wheelhorsepower). It's the same manifold used on the Corolla E11 (bug-eye model) 4E-FE that also has around 87/88 bhp. That Corolla uses the same ignition the 100 bhp does iirc from pictures I have seen.
100 bhp also has other injectors, and the ECU will not 'just bolt on'.

Why not:
-Install 100 bhp manifold
- Buy better fuel (high octane)
- Advance timing (let a professional do that) to avoid getting serious knock/detonation
- get a A/F check and adjust fuelling for better results.

BlackDrako:
The Corolla (European) only had the 4E-FE from 1992. That produced 88 bhp. In 1995 came a 'facelift' version, other grill, other bumpers and small other stuff. The 4E-FE from thet period (until 1997) had 75 bhp. The Corolla after that (bug-eye model) had around 87/88 bhp. That info from wikipedia is probably mentioning the Japanese home market?

:( 75 bhp?
It is worse than I thought...
So what can I do to improve my engine??
beside the manifolds?

:confused:

thanks! It helped me a lot! But I'm still confused... besides my english is not perfect..
If I am not wrong I need:

- different manyfolds
- different ECU
- different injectors (the pink ones I guess)
- and the GT loom... ? what is this?

I read this here in the forum:

"i had the exact same problem when i had a 5e in the starlet before turbo, iv tried to fit the 5e ecu and it did the same as you've described, fired up then died

turned out to be the immobilser cutting out cos the transponder code in the key didn't match the ECU. this problem was removed when i fitted the gt loom though"

Am I forgetting something...?

Marco:

The manifold you're talking about, it's the manifold of the G6?or the common 1.3 Corolla E11?
And the Corolla E10 (92-95) manifold is the the same?

thanks
