Vipec v88 with electronic throttle

[MichaelR32GTR]

Hello 

i currently have a vipec v88 wire in ecu in my r32 Gtr 

i want to get rid of the Hypertune 90mm cable throttle body and go Bosch electronic throttle - drive by wire

is the v88 capable of running electronic throttle control ?

 

also in terms of wiring can anyone help me  out on how the ecu and accelerator pedal and throttle get wired up

im going to run a Nissan stagea drive by wire accelerator pedal 

is it 3 wires from ecu to throttle body, then 3 wires from accelerator cable to throttle body ?

any help would be much appreciated

I'v just finished converting my S15 to DBW
Throttle body 6 wires and Accelerator Pedal 4 wires all ultimately to ECU, sensor supply 5v and sensor GND can be shared of course.

Throttle Body
1. 5v
2. Sensor GND 
3. potentiometer/signal 1  
4. potentiometer/signal 2  
5. Motor +

6. Motor -

Accelerator Pedal 4 wires
1. 5v
2. Sensor GND
3. potentiometer/signal 1  
4. potentiometer/signal 2

That all sounds straight forward

where does the motor on the throttle get is - and + power from ? Would a relay and a 12v power source be needed ?

 

or 12v and ground from ecu

thanks

There are quite specific instructions in the manual - worth reading all of it as it covers:

• motor +/- 
• a relay to provide the ECU with power for the above
• an Aux so the ECU controls the relay
• plus the accelerator sensor and TPS wiring
