Hi Everyone, I have recently got my ECU tuned and everything is working fine. There were some idling problem at start but got rectified when I increased the values in the Idle Target table. My fuel consumption also seems a bit high even though I am not boosting and driving hard. I have a few questions to ask the tuners here to take a look into my base map and log to see what else can be fine tuned just to get a second opinion. I'm a newbie to aftermarket ECU tuning. Tips and suggestion from you guys are highly appreciated. 1. My Idle target is set to 880 rpm once the engine coolant reaches 70 degrees above (see picture) but the engine idles at 900 rpm above. Is this normal? 2. My throttle body has been modified to run mechanically without fly by wire function and I am using and external idle valve to control idle. How much do I need to open the butterfly valve gap when the car is off/idling? 3. Currently the overrun fuel cut is set to off when the throttle is released during cruising. Does this function effect the fuel consumption? Best Regards, Ragupathy Log 2017-02-19 1;53;16 am.llg IdleBaseIdleTarget.docx
