hi,

past few days my car start stalling. its more severe when i press on the clutch and either making a right or left turn. sometime when i turn on my light the rpm will drop from 1000rpm to 400 rpm then go back up to 1000rpm. anyone can help me with this issues? what do u guys thing?

 

If you car is stalling usually you need to recheck your idle% vs Target Table aswell as the options associated with it. And the advanced idle options as well but most of the time tuning the idle% vs Target Table will help you with your results for holding an idle when the enging takes on more or less load.

 

Yep. Follow the idle tuning procedure in the EMS manual. It's pretty simple to do and takes about 15 minutes at most. Once you've got the car idling well at normal operating temperature then you can fine tune the coolant enrichment for cold start and idle.

 

Guys! after a few days of painful brain storming, i think i know why my car is stalling, its after i install the HKS CIRCLE EARTH. do u guys think its possible that it will interfere with idling and stalling?

 

I wouldn't think so but it never hurts to try anything and everything but only one thing at a time. If this only happens when you try to turn your wheel or somthing you might be able to make it better buy richening up your trim tables in the advanced idle section so if it goes below tartet it will feed it more fuel earlier to help with the loading of the stearing pump and condenser. This will probably not totally fix your issue but it can make it better if they currently aren't setup to currently.

If you want hit me on pm and I will give you my email so you can send me your cal file and I will try to point you in the correct direction of things to try if I see anything is out of the ordinary. With Idle it could be alot of things such as even the Idle motor not responding fast enough so you might even be able to compair several things back to the base cal file to get you closer. Either way it can be done so it shouldn't be any issue for you. Let me ask you what size injectors do you have? If they are big you won't be able to idle smoothly at 14.7afr. I run 850's and my car idle perfectly but it runs 13.5afr at idle to do this otherwise it will surge becuase the duty cycle it to low on the big injectors. I idle at 900-950 rpm target.
