evo to dbw

[LoganW]

Hello

I have a early model evo and am in the process of converting to DBW with a bosch e throttle.

The ecu is a g4 plug in for the evo.

Where im at is :

AN volt 3 - TPS main

An volt 4 - TPS sub

AN volt 5 - APS main

An volt 6 - APS sub

But im confused as i dont have a aux 9/10 to get positive and negative for the  e throttle.

How do i know if my ecu has built in ethrottle control?

Alright just checked in my ecu information and it is ethrottle enabled

If its a G4 then it wont have E-throttle.  When you say "early Evo", is it a Evo3 plug-in?

[LoganW]

yes evo 3 plug in, attached is a photo ecu info

Ok as i do some more research and correct me if i am wrong.

I need to use :

ethrottle signal 1 on aux1-4

ethrottle signal 2 on aux 2-8

e-thottle relay - aux1-8

 But the big thing i need to make this work is the external ethrottle module - E-throttle G4 - #G4RET

Yes.
You are right.
You  need external controller for plug in ecu to use dbw.
And do wiring as help file says.

Yes, that would be the suggested way to do it.  Getting rid of the idle valve will free up Aux 5/6/7/8.  You can use one of those for the E-throttle relay and one for signal 2.  Aux 3 is spare for Signal 1.

Alternatively if you have a bit of time up your sleeve you can return your ECU to head office in NZ, and it can be modified with some flying leads added to make aux 9 & 10 available to directly drive the throttle without the external module.
