Wanted EJ22 Manual ECU

Post by **TOONGA** » Sun Feb 24, 2013 6:28 pm

I'm after an EJ22 Manual ECU.

I do know some one in WA has one for me, but I can't remember who that was sorry.

The reason I want one is that mine is from a 4EAT 91 liberty and I would like to try the manual ECU to see if there is any difference.

for reference a 1991 manual ECU

Don't think it was me but you can borrow one of mine from a Gen2 manual wagon.

Anyone got one that I can keep?

Guy I have an Auto one and Im looking to try a manual one.

I just realised I never said what series or gen

Mine is a series 1 gen 1, I would say as the scan tool tells me it is a 90-91 4EAT ECU

Can't you just change the polarity on the auto/man ECU pin?

Im pretty sure Subarino would have done this, but it doesnt stop the scan tool from telling me it is from a 4EAT 90-91 model.

Like it does in this induction and fan noise enhanced video

Pretty sure?
Pin 20 on the second biggest plug or the third pin on the bottom row from the inside (next to smallest plug)end.
Should have no wire connected or measure 7v.

As per below, you already told us.. 91 is Gen1 and EJ22 was only available in the Liberty (unless you stole my blue car)

Nope not yet

and I would only "borrow" it for a very long time

I do know where there are 2 1991 ECU's but he wants lots more money than I have

for reference

the D5 is from the 1991 model and is in the manual sedan as well as the dual range wagon.

I can look in my collection after I get home.. if you like?

sounds good you will probably have one collecting dust and spiders.

Probably but I won't charge you any extra for the dust but depends on how big the spiders are though.. may have to put on a danger fee

I have a pair of brand new leather gloves you can use to shoo them away

Best you bring them then. I think the ECUs are in that box on the racking

Ok Ive Checked this plug and it has a wire attached that has between 0 and .06 of a volt running through it.

I have obtained what I thought was a manual ECU (this morning at the wreckers) Ive plugged it into the car and run the B10 scan tool and Im being told the computer is an 4EAT for a 90-91. (BOGGLE)

How do I get 5 volts to this pin? or 7 volts as Tambox stated (FSM says 5 volts for MT 0 volts for AT)

Cut the wire.
If it is earthed, about 0v, it is set for auto.
If it is open circuit, wire cut, it automatically sits at about 7v.
Changing the computer will have no effect as the other computer will be set as the loom dictates, auto.
Chop, chop into it:D

Post by **TOONGA** » Sat Mar 23, 2013 3:10 pm

Yeah I cut the wire 7 volts but the scan tool still indicates Im still running a 4EAT ECU. What other wires need to be altered? I checked b56 11 which if 0 volts is California mode , yet I have voltage and California is still on

Make sure the park switch wire is open circuit, or not 0v.
As per FSM, check the voltage on the TEST and READ connectors, to confirm auto or manual mode.
