fabiangt79 Posted November 18, 2019 Report Share Posted November 18, 2019 Has anyone wired this toyota Vios with auto transmission 1NZ 1500cc engine? I am using a Fury ECU, factory ecu is still in place, links controlling the fuel, VVTI, ignition, and throttle body. I need some help on the wiring for the auto transmission to retard the ignition timing when I put it in D or R gear, plus shifting on the drive. Now the car jerks very hard because ignition time is too advance when engaged in gear and shifting. Can tech support or anyone advise how to wire in from gearbox to links fury, so it can retard the timing for smooth engagement and shfiting?

Adamw Posted November 18, 2019 Report Share Posted November 18, 2019 What type of signal does the transmission output to request torque reduction? Quote Link to comment Share on other sites More sharing options...
fabiangt79 Posted November 18, 2019 Author Report Share Posted November 18, 2019 I am guessing is a analog signal from the valve body of the transmission to the ECU when shifting for torque reduction, not sure yet but have to check and see. You have a solution already? Quote Link to comment Share on other sites More sharing options...

Adamw Posted November 20, 2019 Report Share Posted November 20, 2019 Need to know more about the signal from the transmission. It would be very uncommon to have an "analog signal". Generally older basic trans from the '90's will just be a simple on/off digital signal, but in later trans there are many other variations like frequency based or some sort of coded digital signal or CAN or multiplex/BEAN. These newer trans usually send the not just a torque reduction request but will also tell the ecu how much to reduce it by as well as timing the shift based on feedback from the ecu. So if you confirm how yours works I will advise if there is anyway work with it. Quote Link to comment Share on other sites More sharing options...
