LoganW Posted July 23, 2020 Report Share Posted July 23, 2020 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 Quote Link to comment Share on other sites More sharing options...
Adamw Posted July 23, 2020 Report Share Posted July 23, 2020 If its a G4 then it wont have E-throttle. When you say "early Evo", is it a Evo3 plug-in? Quote Link to comment Share on other sites More sharing options...
LoganW Posted July 23, 2020 Author Report Share Posted July 23, 2020 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 Quote Link to comment Share on other sites More sharing options...
mldc Posted July 23, 2020 Report Share Posted July 23, 2020 Yes. You are right. You need external controller for plug in ecu to use dbw. And do wiring as help file says. Quote Link to comment Share on other sites More sharing options...
Adamw Posted July 23, 2020 Report Share Posted July 23, 2020 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.
