Toyota ee90 2e to 4efe engine swap

[Hassan1991]

Thats right and you can ground it anywhere.

bro i dont understand !! if possible could please give me a schematic !! cause cooling system is the most important thing i want to be perfect please if you can !

[Hassan1991]

Wait....

[Hassan1991]

when Ignition is ON but fan is off as sensor is short. "Note" here switch is working as a sensor

sensor behaves open so Fan turn On.

[pwuser151220154381]

woow thanks so much !! i didnt expect a Proteus schematic !! damn ur the man !! thumbs up and again thanks alot !

[Hassan1991]

Again bhai never mention.

[pwuser151220154381]

No bro sharing knowledge is one of the greatest thing ive ever seen !! very few does that so hats off to you and everyone !!
btw what is the nominal operational temp on 4efe s ? on what degrees should the fan kick in !! i know that thermostat opens in 82 degrees Celsius !!

[Hassan1991]

Thanks a lot
Should be 85~90C at which engine operate.

hello guys. i was wondering does anyone have a pin out ecu diagram for 89661-10170 ecu? thank you very much for the reply

[Hassan1991]

[pwuser152615605741]

thank you. is it the same as the 10170 one? The car is an automatic transmission starlet. Car does not have a distributor, only 2 coils

[Hassan1991]

Your engine is late generation 4efe having Ignition coils.
In toyota auto and manual pinouts are similar. Just the difference is extra wires for auto.
Yes there about 3 gens of 4efe all have about similar pinouts depending upon no. Of pins

[pwuser152615605741]

many thanks for the reply. another question. i have in total 3 wires going to the ecu from the coils (excluding the 2no. +12v and 2no. ground wires). On each coil there is a solid yellow wire going to the ecu, as per the ecu diagram both wires terminate to pin 8 which says "G2 distributor). I measured each of those wires with the ignition ON and they carry +5V to the coils. The other two wires next to the yellow wires are +0V and one terminates to ecu pin no. 6 IGt and the other to pin no. 19 IDL as per the diagram you have sent. Could you please tell me which wires are IGT and which IGF? is there only one IGT pin for both coils? Thanks for your reply!

[Hassan1991]

never mention.
open the ecu back cover. Complete pinouts were written on the circuit board in these ecu's. On internet i never got my hand's on ignition coils generation pinouts of 4efe

ok thanks

hi bro; I have question. in corolla ee100 or ee90 there is a switch neer the a/c vsv that idle up for head light or ... seem to els for efi. i find it's wire and used it for els in my project(Swap 4afe on corolla ee100). but when i switch lights up this wire has no voltage.What u think. Do you think i am in right way?

[Hassan1991]

No.
VSV is a switch. Which leaks the vacuum when gets 12 voltages.
Just gives 12 voltages to vsv and rpm increases. Because it starts leaking vacuum from intake manifold.
While ELS is electronic load signal for ecu.
Which needs voltages to operate.

[byazdaani]

thank you ,plz look this picture. It use in ee100, near The front glass washer motor
Ther is two vsv, one for a/c and another for headligh idle up in carbi
Like els in efi
What do you think?

The white one connector link to ac amplifier,another i don't know,
I swap 4afe and look up for best source for els.

[Hassan1991]

You're welcome.
You can still manual use thi vsv. I had connected one with head lights in 5af converted to Efi.
I'm not too much in AC stuff but there's seperate pins for A/C amplifier in ecu you can try them.

[byazdaani]

thanks, swap 4afe on my ee100, i create her topic soon,no problem with AC, I want circuit els like factory. In fsm els branches from taillight relay.Your diagram in previous post is great.But i want to know best place for connecting wire for els
I think the wire connect to black vsv in pictures in previous post is best. Do you have picture from your circuit in your car for els
