Kitto Posted April 3, 2018 Report Share Posted April 3, 2018 Hello All Chatting with my tuner about E throttle.. Idle control came up in conversation when using E throttle. Now as i understand, normal E throttle setups use the throttle plate to control idle, does this completely negate the use of a 2 wire ISC solenoid or any ISC for that matter? My concerns with E throttle controlling idle is the lack of resolution, 1% of plate movement has the potential to bypass a large amount of air. He even mentioned one vehicle he had, 0.1% of throttle input was too much in plate opening. When the ignition switch is turned on, does the E throttle crack open X % to allow for base air bypass for starting and idling? IE, the factory ISC has a bleed screw that sets the base bleed air manually and then the ISC takes over for fine adjustment. Another question we both had was when selecting E throttle, is the option still available to use a solenoid valve for ISC rather than the throttle plate for idle? Sorry for all of these questions, i would be able to answer a lot of these if i had the ECU on power already but alas i haven't finalised my configuration yet therefore i haven't starting wiring. Trying to cover off all my bases - reworking wiring is something i certainly do not want. Regards, Quote Link to comment Share on other sites More sharing options...
Simon Posted April 6, 2018 Report Share Posted April 6, 2018 You are correct and the bigger the throttle relative to the engine size the harder the control get for idle over E throttle. It is a nice option to have a dedicated Idle solenoid particularly if its a smaller cc engine with a large throttle. ECU wise you can have E throttle and then all the idle control done conventionally. All the same idle control options exist on E throttle only.
