Had my car undergo a complete engine diagnostics through the ECU the readings are as below:
All sensors and other components are proper :
Ignition advance 5.5
Calculated load 31.76
IAC throttle 12.16
opening postion 0.84
a/c pressure 1080 kpa
Engine Speed 883 rpm
Desired Speed 878
had tried again to manually to set this RPM to 1000 by turning the idle speed screw (wow the car felt so smooth when stationary) but after a restart/engine the ECU again set it back to 878 .
The consultant mentioned that the k series have this problem since its a 3 cylinder engine same as mentioned in the service center, no wonder in a years time wagon r has released 2013 version . also checked wagonr 2013 at the showroom this problem is not present in the new one including Stingray both doors when open from both cars are not vibrating
Please advise. There is no provision of manually changing the RPM since the ECU has some kind of password or something like that which prevents changes
to be made.
The word desirable RPM makes me think it should be editable.
Tired it a second time at home same issues.
Please advise. Do Any of you guys have any other solution. I know the solution is very simple JUST change RPM to 1000 but unable to make such a simple one.
