Toyota Ecu Types

[camerondownunder88]

Hi,

Been doing some reading on Toyota ECU's and found there are a few types of ECU. Analouge and Digital.

 

The old Analogue ones were on the motors like 4K-E and 3t engine etc. It is the L-jetronnic made by Bosch.

 

Now later ones are the TCCS type which are digital eg. 4age.

 

Now I know the 7K-E injections was made later than 4K and the pin out is similar on the 7K one to the 4age one.

 

Can any one tell me for certain if the 7K ECU is of the newer TCCS type?

 

Also does anyone have the 7K-E manual handy I can get emailed?

 

Cheers

Cameron

PM'd you back. As I said forget the stocko/toyota ECU's and just spend a couple of hundy on an aftermarket unit.

Do it once, and do it properly. :P

 

I can send you a diagram for the TPS wiring, and thats about all you need toyota wise, provided you get a wiring diagram with your chosen ECU.

 

Oh and pull the idle control solenoid off and block it with a plate, more trouble than its worth. :)

7K-E's are a late 90's motor. Jetronic has been dead since the late 80's. You'll be able to tell by looking at the dizzy pickups. If it's a 24- 1/4 arrangement, definitely late model digital gear. If there's only 4 prongs under the cap it's a jetronic. I'm sure I've read running a 7K dizzy is the way to go for a late model programmable ignition on a K motor, so I'm fairly sure it'll be a TCCS item.
