henlamb Posted May 11 Report Share Posted May 11 Hi guys Just added a 2 wire idle control onto a 1uzfe with a Gen1 Ver4 seems to operate okay. Quick question, does the ECU generate a min duty cycle for the hold modes eg Idle Hot and Idle Cold? The lowest is 35% even though I’ve entered a value much lower than that?

Adamw Posted May 11 Report Share Posted May 11 What is the firmware code on the micro? I had a quick look in the D42LEXUS firmware and that has hard coded clamps of 5% and 95%. Quote Link to comment Share on other sites More sharing options...
henlamb Posted May 11 Author Report Share Posted May 11 Hi, yep that’s the code! Also does this mean the idle valve operates continuously regardless of throttle position in this “hold mode”? Thanks Henry Quote Link to comment Share on other sites More sharing options...
