I replaced my trailing coil and it still, once the car has heated the tach bounces crazy. From 0rpm to redline. I also removed all of my haltech E6K connections to look for cold solder points.

Could it be possible that the haltech settings are incorrect (this never happened the two years I have been driving it.) Constant charge and set at 4ms. the coil appears to run extremely hot.

Any ideas? does this hurt the car since I think the trailing coils come online then off again continuesly when this happens? Would it be safe to just disconnect it when I hit the track and run without the trailings?

Thanks,
Ian

 

I assumed you logged and your rpm's are fine on the haltech side of it (the whole filter deal)

Try chaning your charge time to 4.5ms. Hitman recommends that for FC's

I can't remember what mine was set at on FC but my FD is 3.5ms.

Are you running after market ignition and what is your output edge set at?

Make sure toggle is on also for aux output.

Might get more help in the haltech section.

 

Thanks for your input. i am sure that the ignition should be set right. It was tuned by steve kan. but the problem exists now especially once warm.

I will try and set it to 4.5ms.
